Product Details

In over half the motor mount bolts I have removed on the older diesel engine, I have found threads that are either stretched, galled, or stripped. This is partly due to the heavy vibrations of the diesel engine. If the threads are badly stripped I recommend you try to find a good used replacement motor mount arm. If they are either stretched of galled you MUST use a thread chaser to "clean up" the threads before reinstalling the bolt or you could end you with some real problems. The bolts can also become stretched.

To learn more watch Kent's Youtube video by clicking on the arrow in the center of the picture above. He will explain the problems, what causes them and how you can minimize future problems. See related products below to purchase new bolts, mounts and other tools that can help you when installing new motor mounts.  

Kent does not recommend using a tap. The teeth are to sharp and you can easily damage the aluminum threads if you do not start the tap perfectly. In order to use this thread chaser you will need to raise the engine and remove the rubber motor mount to give you the proper clearance to work.
