Still don't know how to repair and maintain Sinotruk D10B diesel engines? DNT has a look~

With more and more truck models, engines are becoming more and more "sophisticated", which requires truck drivers to strengthen daily maintenance, extend the life of the engine, and reduce use failures. This issue of DNT editor brings you the precautions for the maintenance of Sinotruk D10B diesel engines.Operation precautions:For the safety and comfort of driving, be sure to perform daily inspections on each component of the diesel engine before use. If any abnormality is found, you can go to the maintenance service station for repair.Before starting the diesel engine, check whether the oil level, coolant level, etc. meet the requirements to ensure safety.When starting the diesel engine, if it fails to start within 5 seconds, it should be restarted after 15 seconds. After starting the diesel engine, it should run at idle speed for 2 to 3 minutes, and the oil pressure should be higher than 100kPa. When the coolant temperature is not higher than 60℃, do not suddenly run at high speed and high load, otherwise it will affect the reliability of the diesel engine. Before stopping a loaded diesel engine, the engine must be deloaded and slowed down, and the idling time must be no less than 5 minutes. During the running-in period (3000km), the diesel engine should only be operated under medium load.

Why are truck repair tools made of carbon steel?

Carbon steel is often used as the material for large vehicle maintenance tools, mainly because it has many advantages in terms of performance, cost, and processability, and is particularly suitable for heavy-duty maintenance scenarios that bear large loads and large torques. The following are the specific reasons:1. High strength and good rigidity Carbon steel has good mechanical strength and rigidity, and can withstand the impact force and high-strength torque commonly seen in large vehicle maintenance, preventing deformation or breakage. 2. Strong wear resistance During the maintenance process, tools often come into contact and rub against metal parts. Carbon steel, especially medium carbon steel and high carbon steel, have strong wear resistance after heat treatment (such as quenching and tempering), which prolongs the life of the tool. 3. Easy to process and shape Carbon steel has good machinability and is easy to carry out: Forging (such as wrenches and sockets) Turning and milling (such as maintenance tools) Heat treatment and surface treatment (such as chrome plating, blackening, etc.) 4. Excellent heat treatment performance Carbon steel can obtain the required hardness and toughness after quenching and tempering, and adapt to different working conditions. 5. Low cost and easy to obtain Compared with alloy steel, stainless steel and other materials, carbon steel is cheaper and more widely available, which is conducive to controlling manufacturing costs, and is particularly suitable for low-end or mass production. 6. Various surface treatments are available Although carbon steel itself has average corrosion resistance, it can be treated with nickel plating, chrome plating, blackening, phosphating and other surface treatments to improve its appearance and rust resistance, taking into account both function and aesthetics.

Causes of crankshaft oil seal leakage

Nowadays, the weather is cold and windy in winter. If people don't take good care of their bodies, they will have problems. Not to mention the car outside in the wind, sun and cold weather, oil leakage is also very common. The following editor will share with you the reasons for the crankshaft rear oil seal leakage. Let's take a look~① The crankshaft oil seal did not use non-petroleum-based lubricants during the press-fitting process, which caused the oil seal to loosen or even fall off after the engine was used for a period of time (for example, some engine manufacturers use engine oil instead of relatively expensive non-petroleum-based lubricants to reduce manufacturing costs).② The parallelism of the rear oil seal press-fitting surface to the rear oil seal seat mounting surface did not meet the technical requirements of the assembly drawing, causing the rear oil seal lip to be unevenly stressed and deformed. After the engine was used for a period of time, the oil seal lip was deformed or even the entire oil seal was twisted, causing the oil seal to be damaged and leak oil.③ The engine has been in use for a long time, and the rear oil seal has naturally aged and cracks have occurred at the lip, causing oil leakage.Although the oil seal is small, it has a great responsibility. Once the oil leaks, the engine may lack oil and wear, and the leaking oil may also have certain hidden dangers, so check it frequently. How to install the crankshaft oil seal?①First, use 2 M12*1.5*40mm hexagon socket bolts to fix the guide shaft to the front section of the engine crankshaft, and tighten it with a hexagon socket wrench;②Then install the crankshaft front oil seal on the guide shaft, and the guide shaft plays a guiding role;③Install the pressure plate on the guide shaft, and use a movable wrench to turn the nut so that the pressure plate presses the oil seal into place;④Remove the special maintenance tool, and the crankshaft front oil seal is installed.If you are interested in this aspect, you can contact us at any time

Don't stop when the truck stops. These maintenance can't be stopped. Tanaka transmission repair tool

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. It is made of international standard steel and processed with humanized design concepts. It has high strength and can be used twice as many times as ordinary steel without damage.

Fast Gearbox Repair Tool Manual - Common Faults and Troubleshooting

Fast Gearbox Repair Tool Manual - Common Faults and Troubleshooting: Overheating of the Transmission.The long-term operating temperature of the transmission should not exceed 120°C. If this temperature is exceeded, the lubricating oil will deteriorate and the life of the transmission will be affected.Due to the friction of the moving parts, the transmission will generate a certain amount of heat. The normal operating temperature is about 38°C higher than the ambient temperature. The heat is dissipated through the transmission housing. If the heat dissipation is not normal, it will cause overheating.Before looking for the cause of overheating, the oil temperature gauge and oil temperature sensor must be checked to ensure that the reading of the oil temperature gauge is correct.Generally, overheating is caused by the following reasons:1) Improper lubrication. The oil level is too low or too high, the oil grade is wrong, or the transmission working angle exceeds 12°.2) The driving speed is usually below 32Km/h.3) The engine speed is too high;4) The airflow around the transmission is blocked because the transmission is surrounded by the frame, floor, fuel tank and installed between the large bumper assembly;5) The engine exhaust system is too close to the transmission;6) The ambient temperature is too high;7) Overloading and speeding.

Truck Tips: How to adjust 5th wheels and trailer bogeys

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.
