Which Bearing Pullers Are Used in Truck Repair?Truck repair commonly calls for external jaw pullers, bearing separators, internal pullers, and hydraulic pullers. The right choice depends on whether the bearing is exposed on a shaft, recessed in a housing, tightly seated with little clearance, or seized in a heavy-duty wheel-end or drivetrain assembly.Use a puller that contacts the race being removed, stays centered on the shaft or housing, and has adequate reach and capacity. A controlled pull helps reduce the risk of scoring a shaft, distorting a hub, or damaging a reusable component.Controlled pulling starts with a stable, centered setup and the correct contact point.Why Truck Repairs Need Controlled ExtractionTruck bearings often sit in large hubs, transmissions, differentials, accessory drives, and support assemblies. Corrosion, press fits, heat cycles, and limited access can make removal difficult. Pullers apply axial force gradually, which gives the technician time to check alignment and stop before surrounding parts are overloaded.Common Truck Bearing LocationsWheel-end and hub assemblies: bearings, hubs, and related components may need dedicated hub tooling or a separator-backed puller.Transmission and gearbox shafts: exposed bearings may be removed with external jaws or a separator when clearance is tight.Driveline and accessory components: pullers can help remove bearings, gears, pulleys, and similar press-fit parts when the service procedure permits.Blind bores and housings: internal pullers with expanding collets are used where an outside gripping edge is unavailable.Choose an External Jaw Puller for Accessible BearingsA two- or three-jaw puller is suitable when the back of the bearing or component is accessible. Three jaws usually distribute force more evenly when clearance allows. Position each jaw behind a solid pulling surface rather than against a cage, seal, or thin shield.Jaw placement and center-screw alignment determine whether the load stays controlled.Use a Bearing Separator When Clearance Is LimitedWhen a bearing sits close to a shoulder and hooks cannot get behind it, a bearing separator can create a secure pulling surface. Fit the separator squarely behind the bearing race, then connect it to a puller or a suitable forcing arrangement. Do not use a separator on a surface that cannot carry the extraction load.Select an Internal Puller for Recessed BearingsInternal or blind-bearing pullers use an expanding collet inside the bearing bore. They are useful for components seated in housings where the outside edge cannot be gripped. Match the collet range to the bore and follow the vehicle or component service procedure for the correct pulling direction and support.When a Hydraulic Bearing Puller Is the Better ChoiceHydraulic pullers are often considered for large, seized, or high-interference truck components because they can provide higher, smoother extraction force than a hand screw. Capacity alone is not enough: confirm the puller span, reach, support arrangement, and component-specific service limits before applying pressure.Truck wheel-end and drivetrain jobs require adequate support, clearance, and inspection space.Set Up the Puller Before Applying ForceSecure the truck or removed assembly according to the applicable service procedure.Clean enough of the component to identify the bearing race and available gripping surface.Measure the puller span, reach, and bore or outside diameter before choosing attachments.Center the forcing screw or hydraulic ram on a suitable support point.Apply force gradually and recheck jaw engagement after the first movement.Safety Checks for Heavy-Duty Truck WorkWear eye protection and keep people out of the line of force. Inspect puller arms, threads, adapters, and hydraulic hoses before use. Never exceed the rated capacity, heat a component unless the approved procedure allows it, or continue if the puller slips, bends, or loads a thin casting unevenly.When to Stop and Change the MethodStop when the bearing does not move under a reasonable, controlled load; the jaws begin to walk; the center point starts to damage the shaft; or a casting shows signs of stress. The correct next step may be a separator, internal puller, hydraulic setup, press fixture, or specialist support, depending on the component and service information.Inspect the Assembly After Bearing RemovalAfter extraction, inspect the shaft, bore, shoulder, seal land, and removed bearing race for scoring, fretting, cracks, or heat marks. Clean the seating area and use the correct installation method for the replacement bearing. Pulling force should never be used to install a bearing unless the approved procedure specifically calls for it.How DNT Tools Can Support Truck Repair TeamsDNT Tools can help workshops and distributors evaluate puller configurations for truck bearing service, including external, internal, separator, and hydraulic solutions. For a setup question tied to your bearing size, access, and application, contact the support team with the component details.

Where Are Bearing Pullers Commonly Used?Bearing pullers are used wherever a bearing, gear, pulley, hub, sleeve, or coupling is press-fitted to a shaft or installed in a housing. The correct tool applies controlled force without damaging surrounding parts.Controlled pulling helps protect the shaft, bearing seat, and nearby gear components.Transmission and Gearbox ServiceTechnicians use jaw, separator, internal, and blind-hole pullers to remove shaft bearings, gears, sleeves, and housing-mounted components during transmission repair.Wheel Hub and Axle WorkHub and axle applications may involve tight fits and high loads. Use equipment rated for the job and support the assembly so the pull stays straight.Grip the fitted ring or a correctly supported separator, not the rolling elements or cage.Pulley and Gear RemovalA puller can remove pulleys, gears, and couplings when it grips a strong shoulder behind the component. Protect the shaft end with the correct point or adapter.Electric Motor and Industrial MaintenanceMotors, pumps, conveyors, and gear reducers commonly need bearing removal during planned maintenance. Internal pullers are useful where a bearing sits in a housing.Agricultural and Heavy Equipment RepairsLarge machinery often requires longer reach, greater capacity, and hydraulic assistance. Verify access and tool rating before applying force to a seized component.Clean access, stable support, and correct alignment reduce the chance of secondary damage.Match the Puller to the Access ProblemChoose by component diameter, reach, spread, available grip surface, and expected load. A separator or internal puller is often safer than forcing standard jaws into poor access.Use Controlled Force and Inspect the ResultKeep the forcing screw centered, increase force gradually, and stop when a component distorts or the tool shifts. Inspect mating surfaces before fitting the replacement part.For application guidance on workshop-ready puller tooling, contact DNT Tools.

What Bearing Puller Is Best for Transmission Repair?Use a puller that matches the bearing location and access: a jaw puller for exposed shaft-mounted parts, an internal puller for housing bores, a separator where no lip is available, and hydraulic force for large or seized assemblies.Controlled pulling helps protect the shaft, bearing seat, and nearby gear components.Start With the Bearing LocationIdentify whether the bearing is on a shaft, recessed in a case, behind a gear, or installed in a blind bore. The location determines the grip method before capacity is considered.Choose Jaw Pullers for Accessible Shaft BearingsTwo- or three-jaw pullers can remove exposed bearings, gears, sleeves, and hubs when the jaws can seat squarely behind a solid pulling surface. Three jaws generally improve centering where clearance permits.Grip the fitted ring or a correctly supported separator, not the rolling elements or cage.Use a Separator When There Is No Safe Jaw LipA bearing separator creates a supported edge behind a tight race. Pair it with puller legs or a bridge so force travels along the shaft centerline instead of through the cage.Use Internal or Blind-Hole Pullers for Case BearingsExpanding collets and bridge pullers are suited to bearings located inside transmission housings. Match the collet range to the bore and use the vehicle repair procedure for any special steps.Select Hydraulic Force for High-Load JobsHydraulic pullers help with large, corroded, or heavy-duty transmission components, but they still require a rated setup, stable support, and careful alignment.Clean access, stable support, and correct alignment reduce the chance of secondary damage.Avoid Common Transmission Removal DamageDo not pull on thin gear teeth, rolling elements, seals, or aluminum housing edges. Stop if jaws shift, the screw bends, or resistance rises beyond the tool rating.Check Before ReassemblyInspect the shaft, bore, race seat, and retaining features after removal. Follow the manufacturer procedure for installation force, lubrication, torque, and bearing preload.For application guidance on workshop-ready puller tooling, contact DNT Tools.

How to Bleed Brakes SafelyBleed brakes only after confirming the correct brake-fluid specification and the wheel sequence in the vehicle service information. Keep the reservoir above the minimum mark, work one bleeder at a time, and stop if the pedal remains soft or a leak is visible. A pressure or vacuum brake bleeder can make a one-person job more controlled, but no tool replaces the factory procedure for your exact vehicle.A clear hose and catch bottle help you monitor fluid and air during brake service.Brake Bleeding Tools ChecklistEssential itemsFresh, sealed brake fluid of the exact specified typeCorrect-size flare or box wrench for each bleed screwClear hose and a compatible catch bottleGloves, eye protection, absorbent rags, and wheel-support equipmentUseful upgradesVacuum brake bleeder for extracting fluid at the caliperPressure brake bleeder with the correct reservoir adapterFluid syringe or extractor for reservoir serviceService manual or approved repair information for sequence and torqueChoose Pedal, Vacuum, or Pressure BleedingMethodBest useWatch carefullyTwo-person pedal bleedingBasic service when a helper is availableClose the screw before the pedal is released; do not force pedal travel beyond the vehicle guidance.Vacuum bleedingOne-person fluid exchange and inspectionAir can appear at loose hose or screw threads, so confirm the source before assuming air remains in the circuit.Pressure bleedingConsistent fluid delivery and workshop workflowsUse the correct cap adapter and the pressure specified by the equipment and vehicle documentation.A hand pump, clear hose, catch bottle, gloves, and wrenches support a controlled setup.Before You Open a Bleeder ScrewPark on level ground, secure the vehicle, and support it correctly before removing a wheel.Read the required fluid type, bleed order, ABS notes, and torque information for the exact model.Clean around the reservoir and bleeder screw so dirt cannot enter the hydraulic system.Fit the wrench and hose before opening the screw; route used fluid into a suitable container.Step-by-Step Brake Bleeding ProcedureFill the reservoir with new, specified brake fluid and keep it above the minimum line throughout the job.Begin at the wheel specified by the vehicle procedure, not a guessed universal order.Apply the chosen method, open the bleeder only as needed, and watch the clear hose for bubbles and fluid condition.Close the bleeder before releasing pedal pressure or removing the tool connection.Recheck the reservoir level, then repeat at the remaining wheels in the documented sequence.When finished, set the fluid level correctly, clean spills promptly, and install protective caps.How to Keep Air Out of the SystemMost failed bleeding attempts start with an empty reservoir, an open screw at the wrong moment, or a loose connection that lets air enter or appear in the hose. Refill the reservoir often, keep the clear hose seated, and isolate one wheel at a time. Do not reuse drained fluid.ABS, Electronic Brakes, and Vehicle-Specific SequencesSome ABS, electronic brake, and brake-by-wire systems require a scan-tool routine, a defined pressure method, or a special sequence to move fluid through the modulator. Do not assume a conventional four-wheel bleed will remove air from every circuit. Follow the manufacturer repair information; when a required diagnostic function is unavailable, use a qualified technician.Keep the reservoir supplied with the specified fluid throughout the procedure.Troubleshooting a Soft Pedal After BleedingPedal still soft: Recheck the documented sequence, fluid level, hose connections, and visible leaks.Bubbles never stop: Inspect the hose and bleeder connection for external air entry before repeating the entire process.Fluid leak or damaged screw: Stop work. Repair the fault before testing brake performance.ABS warning or unusual pedal behavior: Follow the exact diagnostic procedure for the vehicle instead of continuing with generic steps.Final Checks Before Road TestingWith every bleed screw secured, confirm the reservoir level, check for leaks, and apply the brake pedal with the engine off and then as specified for the vehicle. The pedal should feel firm and stable. Do not road-test a vehicle with a soft pedal, a warning light, or any sign of fluid leakage.For workshop-ready brake service tools and application guidance, contact DNT Tools.

DNT Tools Support How Do I Choose and Use a Bearing Puller Without Damaging the Shaft? Choose a bearing puller by the bearing location, the available gripping surface, the required reach, and the force needed. Use an external two-jaw or three-jaw puller when the bearing is accessible on a shaft; use an internal or blind bearing puller when the bearing sits in a housing; add a bearing separator when there is little purchase behind the ring. Keep the forcing screw centered, pull on the ring with the interference fit, and stop if the tool begins to tilt, slip, or overload. Prepare the correct puller, safety equipment, and support accessories before applying force. What Is a Bearing Puller Used For? A bearing puller is a removal tool for press-fit bearings and similar components on shafts or in housings. Its center screw or hydraulic ram applies controlled extraction force while jaws, a separator, or internal collets hold the component. The aim is to remove the bearing without scoring the shaft, distorting the housing, or sending load through parts that should not carry it. For routine maintenance, a correctly matched puller is usually more controlled than striking a bearing with a hammer. It also makes alignment and repeatable removal easier to inspect. Which Bearing Puller Type Fits Your Job? External jaw puller Use when jaws can grip behind an exposed bearing, gear, pulley, or hub. Reversible jaws can support inside or outside pulling where access allows. Internal bearing puller Use for bearings seated in a housing, especially when the outer ring is the fitted ring and there is no external edge to grip. Bearing separator puller Use when there is minimal clearance behind the bearing. The separator creates a positive bearing surface for the puller legs or strong back. Hydraulic bearing puller Use for larger or tighter assemblies that need higher, more controlled extraction force than a mechanical screw puller can provide. Tool selection begins with access, geometry, and force requirements rather than a one-size-fits-all puller. Should You Use a 2-Jaw or 3-Jaw Bearing Puller? PullerBest fitKey consideration 2-jaw pullerTight or obstructed accessSet both jaws evenly and check that the pull is not off-center. 3-jaw pullerOpen, round components with room around themThree contact points generally improve balance and reduce the tendency to tilt. Neither design is automatically better. Choose the one that gives secure, symmetrical contact behind the correct ring without fouling nearby components. When Do You Need a Bearing Separator? Use a bearing separator when a jaw cannot get securely behind the bearing inner ring or when the clearance between the bearing and the shaft shoulder is very small. Fit the separator halves close to the ring, tighten them evenly, then connect the separator to a puller or strong back. This setup helps keep the extraction load close to the bearing instead of concentrating it on a thin edge. Do not use a separator that is too large or leave an uneven gap between its halves. A loose separator can slip suddenly under load. What Size Bearing Puller Do You Need? Grip range: The jaws or separator must reach the bearing diameter without running at the end of their travel. Reach: The legs must extend past the bearing and leave room for the crosshead and forcing screw. Capacity: Choose a puller rated for the likely extraction load, with a margin for fit, corrosion, and service conditions. Contact geometry: Confirm that the tool bears on the ring with the interference fit and not on the cage, seal, or rolling elements. Measure before selecting. A puller that is nominally strong enough can still be unsuitable if its grip width, reach, or jaw profile does not match the assembly. Controlled setup and alignment matter as much as puller capacity during bearing removal. How Do You Use a Bearing Puller Safely? Isolate the machine, remove guards as required, clean the area, and wear appropriate eye protection. Identify the fitted ring and select an external, internal, separator, or hydraulic puller that can grip it securely. Position the jaws, separator, or collet evenly. Center the forcing screw on the shaft end or approved support point. Apply force gradually. Recheck alignment after the first movement and keep hands clear of the loaded tool. Stop when the bearing releases, then support it so it cannot fall or damage nearby parts. How Do You Remove a Stuck Bearing? First confirm that every retaining feature has been removed, including locknuts, snap rings, collars, set screws, and covers. Clean exposed corrosion and recheck that the puller bears on the correct ring. If a mechanical puller requires excessive torque, do not extend it with improvised levers. Reassess the puller capacity and setup; a hydraulic puller, separator arrangement, or approved thermal method may be more suitable for the assembly. Which Mistakes Can Damage the Shaft or Housing? Pulling through rolling elements instead of acting on the fitted ring. Running the forcing screw off-center or allowing one jaw to sit higher than the others. Using damaged, bent, or undersized jaws, legs, separator halves, or fasteners. Applying impact to a loaded puller or continuing after the tool starts to flex, slip, or bind. Forcing removal before checking for hidden retainers, adhesive, corrosion, or interference features. Can an Internal or Blind Bearing Puller Remove a Bearing From a Housing? Yes. An internal bearing puller uses an expanding collet or adapter to grip the bearing from inside its bore, allowing a slide hammer or support bridge to extract it from the housing. Match the adapter to the bearing bore and follow the tool's specified grip range. This is the preferred approach when neither ring has enough external access for conventional jaws. Why Choose DNT Tools for Bearing Puller Support? DNT Tools can help you match a bearing puller configuration to your measured grip range, reach, access conditions, and service environment. Share the bearing dimensions, mounting position, and any access limitations so the correct mechanical, separator, internal, or hydraulic solution can be considered before removal begins.

Operate and use the transmission correctly and reasonably, and perform regular maintenance. DNT editor has extracted some maintenance methods from the Fast transmission repair tool manual for your reference:1. Check the oil level position. The oil level should be flush with the lower edge of the oil level observation hole and should not be 5mm lower than the lower edge of the oil level observation hole. Too much oil filling will cause the transmission temperature to rise and oil leakage; too little oil filling will cause poor lubrication of parts, and in severe cases, a burning accident will occur.2. Oil change cycle. The lubricant must be replaced when the new transmission travels 2000~5000km. The oil level and leakage of the lubricant should be checked every 10000km, and it should be replenished at any time. The lubricant should be replaced every 50000~80000km.3. Working temperature. The temperature of the transmission during continuous operation shall not exceed 120℃, and the temperature shall not be lower than -40℃. When the working temperature exceeds 120℃, the lubricant will decompose and shorten the life of the transmission.4. Working inclination angle When the working inclination angle of the transmission exceeds 12°, the lubrication may not be sufficient. A lubricating oil pump or cooling device can be installed to ensure good lubrication.In case of a failure, don't try any treatment to save some money, which may easily cause more serious failures. It is better to find a regular service station or repair shop, because there are special repair tools for gearbox repair. Take our Fast gearbox special repair tools as an example: Fast gearbox repair tools This set of Fast gearbox is specially designed and produced for Fast.

Because of commercial vehicle gross-weight and axle-weight regulations, drivers will occasionally need to reposition the 5th wheel or the trailer axles for proper weight distribution. This video explains how to slide the 5th wheel and the trailer axles safely and without damaging the equipment. After taking on a load, especially a heavy load, it’s advisable to axle-weigh the truck if possible before beginning the trip. Overweight fines are expensive and go against the fleet’s safety record. If, after axle-weighing the truck, you discover the drive axles are 800 pounds overweight, but the steer axle is still below its legal limit, you will need to shift that weight forward to the steer axle by sliding the 5th wheel forward. Generally, weight will transfer at about 100 pounds per inch. In this example, you will have to slide the fifth wheel forward about eight inches. If, after axle-weighing the truck, you discover the drive axles are 800 pounds overweight, but the steer axle is still below its legal limit, you will need to shift that weight forward to the steer axle by sliding the 5th wheel forward. Generally, weight will transfer at about 100 pounds per inch. In this example, you will have to slide the fifth wheel forward about eight inches.Where to lower the landing gearTo ease the strain on the driveline, you’ll need to lower the trailer landing gear to support the weight. Look for solid even ground upon which to lower the landing gear, then place wheel chocks around the trailer wheels. Crank the landing gear down to about two inches from the ground, then climb into the cab and deflate the tractor air suspension. The landing gear will settle to the ground, taking the weight off the tractor frame. As the suspension deflates, unlock the 5th wheel slider lock, then exit the cab to verify the locks have released, and to ensure the tractor is not dangling from the trailer king pin. With the weight off the 5th wheel, it should slide easily.It will help if you mark two spots on the ground as a reference for how far the 5th wheel needs to move. In this case, we placed a pair of gloves on the ground beside the tires as guides. Back in the cab, place the transmission in reverse, as in this case you’ll be sliding the 5th wheel forward. Release the tractor parking brakes and gently apply some throttle. After sliding the appropriate distance, set the tractor brake and exit the cab to verify the 5th wheel is now in the correct position. If the move was successful, re-enter the cab and re-engage the 5th wheel slide locking mechanism. Release the parking brakes and place the transmission in drive or reverse. Gently rock the truck back and forth to seat the slider locks.Verify the slider locks have engaged, then re-inflate the tractor suspension.As the suspension is inflating, set the tractor parking brakes. Exit the cab and crank up the landing gear and fetch the wheel chocks from the trailer. Before releasing the trailer parking brakes, do one more tug test to ensure the slider locks are fully engaged.How to slide a trailer bogeyNext, we’ll look at sliding the trailer bogeys.As with the 5th wheel, repositioning the trailer axles can help with weight distribution. If the trailer axles are overweight, sliding them back can transfer weight to the drive axles. Conversely, if the drive axles are overweight and the weight cannot be transferred to the steer axle, sliding the trailer bogeys forward can take some weight off the drive axles.Unfortunately, there’s no way to take the weight off the trailer axles before sliding them, as we could with the 5th wheel by lowering the landing gear. It’s advisable to check before loading the trailer that the trailer axles are in the proper position — that is, no more than 41 feet or 12.5 meters behind the trailer king pin — and that the trailer-axle slider locks are working and the axles can slideMost trailers have an air-activated release for the locking mechanism, and usually, the trailer parking brake must be set for the locks to disengage. Also, the trailer air suspension may deflate when the parking brakes are set. When the trailer is loaded, the locking pins usually will not disengage when you flip the switch. To disengage the pins, you may have to rock the tractor back and forth with the trailer brakes set.As with the 5th wheel slider, make the current position of the locking pins with tape, chalk, or a sticky note. Also mark the position you what to slide the axles to. Release the locking pins, and deflate the trailer air suspension.In the cab, release the tractor parking brakes, place the transmission in the direction you want to slide the trailer axles, and gently apply throttle. Be aware the slider locks may break free suddenly, so be ready to release the throttle pedal immediately. Set the tractor parking brakes, exit the cab, and verify the trailer axles are now in the position you want them to be. Since the locking holes are usually spaced four or six inches apart, you will shift about 250 pounds per hole for four-inch spacing, and 400 pounds for six-inch spacing.With the trailer axles successfully repositioned, re-engage the locking mechanism. The pins may not be perfectly centered on the holes, so you may need to rock the tractor back and forth to get the pins to engage. Do not venture out onto the road until the locks are engaged. If you have difficulty engaging the locks, driving slowly around and applying the trailer brakes can help. So does driving around on uneven ground. Gather up the wheel chocks, check for lock-pin engagement, and be sure the trailer suspension is re-inflated before driving to the scale to reweigh the truck.

Common Types of Automotive Tools list Automotive tools are many types, so many that it’s almost impossible to own them all. Your tool choices depend on several factors, chief among them necessity.

How to Maintain a Motorbike/motorcycle Lots of people get a little lazy about motorcycle maintenance over time. To keep your bike in good running condition, periodic maintenance is extremely important. Maintaining your bike regularly helps it to perform at its peak and ensures that you can enjoy safe, problem-free riding. A lot of the basic servicing jobs are easy enough to do yourself.Doing Specific Maintenance Tasks1. Check the tire condition regularly. You should change the tires when you notice a change in the way the bike handles, as specified by local legislation, or at the very latest when the tread is worn down to the wear bars. Under-inflated tires will overheat and may fail.  Over-inflated tires will give less than optimal grip.Ideally, check tire pressure before and after every journey. Commit to a weekly checking routine. Replace the tires if there is rapid pressure loss. Replace when there is about 1.59mm (2/32” or 0.063 inches) tread remaining all around the tire. Don’t wait till tires go bald. Always change tires in sets. Both tires go through the same stresses and rigors of road riding.2. Check and top up or replace engine oil. It lubricates your gears and engines; not changing the engine oil will cause damage to the engine. The owner's manual will specify how frequently the oil should be changed and this schedule should be followed.Check for any possible oil leakages. Carbon deposits thicken the oil, creating a drag in the movement of engine. Avoid running your bike on dirty oil. It will increase the consumption of fuel and drastically reduce the engine life. 3. Always keep the air filter clean.  A clean air filter helps your engine breathe, which directly impacts its performance and can contribute to a longer engine life.Always change the air filter at recommended intervals; increase the cleaning frequency in particularly dusty conditions.4. Adjust the clutch correctly as needed. It should have the right amount of free play. Don’t tighten your clutch too much – an over-tightened clutch may cause it to slip without your noticing. It also leads to increase in fuel consumption. Make sure you have the right clutch adjustments in place5. Service your engine regularly. Tune it up to keep the engine running like clockwork and reduce your fuel consumption.Clean the carburetor and maintain valve clearances. Clean out the carburetor, for every 1500 kilometers (900 miles) you travel. Clean the spark plugs and check the gap every 750 kilometers (450 miles) for an old / antique two-stroke motorbike and every 1,500 kilometers (900 miles) for a four-stroke bike. Spark plugs should be changed as specified in the owner's manual (or if a problem is suspected). It is critically important to use the correct spark plug grade and type.6. Keep the choke clean and have it replaced immediately if it is damagedMaintain the transmission system. If your bike chain is not lubricated, it may be damaged due to excess heat, and will wear out. This cumulative wear on all the separate links makes the chain loose, and more likely to fall off the sprockets. This can be very dangerous.● Provide regular lubrication, as well as cleaning and adjustment. ● Use paraffin to wash the chain. ● Use a piece of cloth and a soft brush to remove the dirt in the chain. Never use water to clean the chains, as that could rust the chain links. ● Wipe the chain with a clean dry cloth, once the dirt has been cleaned completely. ● Use your old engine oil to lubricate the chain links and the chain. Ensure that your bike’s chain has the proper tension and free play. Any variation will not power the rear wheel smoothly.7. Clean the bike regularly. Keeping it clean of dirt (and salt in winter) will not only make it look nice but will help with maintenance, too.[8] It also makes it easier to notice missing or loose boltExamine for any leakages from the battery. Keep the battery fully charged if the motorcycle is not used for long times and nuts.● Cover the ignition switch unit, ignition coil and silencer using plastic sheets, before you start cleaning the motorcycle.● Use a microfiber cloth to clean your bike. ● Avoid exposing your bike to direct sunlight; try to park your bike in the shade. 8. Maintain your bike's battery. Do periodic maintenance to ensure a long and trouble-free battery life. ● Top up the battery with distilled water, whenever required.● Examine for any leakages from the battery. ● Keep the battery fully charged if the motorcycle is not used for long time.9. Maintain your brakes. ● Keep both the brakes holding the tire properly spaced. Brakes becoming too tight, or too loose, can be very dangerous. ● Tighten the brakes as per your personal style and requirement. ● Replace the bike’s brake pads in the front if screeching sound persists; this could also be because of a lack of oil. ● Replace all the front and rear brake oil with recommended (DOT 3 / 4 / 5) specification. 10. Check the fork and fork oil.● Change your bike’s fork oil, for once in every 12000 kilometers. ● Check forks and spring for rust or damage. ● Adjust your fork according to your preferences and comfort.11. Check the sprockets. Replace them when necessary.● The usual wear-out limit for sprockets is 40,000 kilometers (25,000 miles). ● Change both the driving and driven sprockets, and the chain, at the same time. It's not recommended to change only one part.Following a Maintenance Schedule1. Check some basics on your bike every day, or every time you read. To perform this kind of regular check/maintenance, you should: ● Check the fuel level every day to confirm you're not leaking any fuel. ● Check all your fluid levels - oil, brake fluid and coolant, if applicable. ● Check the throttle cable play. Confirm smooth operation and that it returns properly to the closed position. ● Check steering lock and lever notches for any uneven feel or interference with the operation of any cables at full lock. ● Check brake pedal play, as specified in your motorcycle's manual. Confirm the wear lining indicator is within usable range. ● Check drive chain slack, as specified in your manual. ● Check your lights and horn. ● Check the clutch lever play. ● Ensure smooth steering movement. Make sure there are no restrictions. ● Ensure both bike stands return to their fully upright position. ● Check the correct inflation pressure in both tires. Make sure you have adequate tire tread depth and no cracks or splits. ● Adjust the rear viewing span of mirror if needed. ● Ensure kill switch functionality. ● Check brake hoses for chafing or leakage.2. Do weekly maintenance. Take care of these checks weekly or every 200 miles, whichever is sooner. ● Check oil level - does it require topping-up? Top up if so. ● Check your tire pressure with an accurate gauge. ● Check the battery. If it's not maintenance-free, then check the electrolyte level and top up with distilled water if necessary. ● Check the control cables. Lubricate as necessary ● Check the brakes. Pads and disks should be checked for wear and replaced if necessary. ● Check and top-up your fluids. ● Adjust the drum brakes as necessary. ● Do a full visual inspection. Check for loose nuts and bolts and spokes. ● Check for fork seal leaks and any other oil leaks. 3. Do a monthly check. Perform these tasks every month or every 1,000 miles (whichever is sooner). ● Check the spark plugs. Clean and adjust or replace;[12] anything other than a light/medium brown deposit may indicate problems. ● Check control cables. Adjust for free play. ● Check Idle speed. Adjust as necessary. ● Lubricate control lever pivots.4. Perform quarterly maintenance. Check these items once every three months, or 2,500 miles (whichever is sooner). ● Change the oil and filter. ● Change the air filter. ● Check wheel and steering head bearings and grease them. Replace if necessary. ● Check the exhaust system for leakage. 5. Do a semi-annual review. Check these items twice a year, or every 5,000 miles (whichever is sooner).● Adjust carburetor synchronization - if applicable. ● Check overflow pipes. Replace any that are blocked or missing.6. Do annual maintenance. Complete these checks every year or every 10,000 miles (whichever is sooner). Do all the above half-yearly maintenance tasks. Replace spark plugs. Check suspension linkages for play. Replace linkage, bearings, and bushes as necessary.
