Injector Puller
At DNT Tools,we sell a range of injector removal tools for removing seized and stubborn injectors. Injectors stuck in engines has been an ongoing problem in the automotive sector since the common rail diesel was created. The reason injectors seize is because of galvanic corrosion which occurs when aluminium (the cylinder head of the vehicle) comes into contact with steel (the injector) in a wet environment, this form of corrosion makes the injectors almost impossible to remove meaning more high capacity equipment is needed to remove the injectors such as pneumatic pullers.
Types is recommend following:
Injector puller removal has been an issue in the automotive industry for many years, the problem tends to be due to the injectors seizing. This happens because of galvanic corrosion which happens when aluminium, which is usually at the head of the vehicle, comes into contact with steel, which is the injector, in a wet environment. The form of this corrosion will make the injectors almost impossible to remove and will result in high capacity equipment being used to remove and dismantle injectors, this could be a Hydraulic Injector puller or pneumatic injector puller
How do you use an injector puller?
Injector pullers are essential as they are what injects fuel into the vehicle cylinder, due to their continuous use, they can be prone to breaks, cracks and other physical wear, with this in mind, you may need a new injector puller if your engine is rough, your accelerating slow, misfiring or their issues with mileage or leaks. Fuel injectors help to remove injectors that are needed for testing and cleaning as well as replacements. You will need to select the puller attachment then slide it onto the injector using a screw or slide hammer, this will safely remove the injector. Once the injector has been pulled you can remove the old seal with a screwdriver. In order to fit the new seal you will need to use the assembly cone on the tip of the injector, then slide the new seal onto the cone, you can then use the sleeve to slide the seal onto the injector.
How to use a diesel injector puller?
First open the bonnet, then find the valve cover on the engine, remove the bolts using a wrench then pull the valve cover from the engine. Next find the injector fuel lines that supply the injector, screw into the engine near the injector, the injectors will all have their own supply line. You can then remove the nut that keeps the supply line to the injector in place, then pull the fuel supply line out of the engine with your hands. You will then need to find the injector hold down which will be held in place with two bolts, you can remove these bolts and pull the injector away from the engine. Hold the top end of the injector and pull it out, you can then replace the injector should you need too.
