Troubleshooting & FAQ
How do I know if this bushing fits my engine?
Confirm your model is listed in the Engine & Model Compatibility table. The most reliable method is to verify that your original part number matches one of the cross-references in our Part Number Matrix.
What are the signs of a failing chain wheel bushing?
Symptoms typically include grinding noises during engine start-up, the starter motor spinning without engaging the engine, or inconsistent starting. A visual inspection during a starter rebuild may also reveal obvious wear, cracking, or deformation.
What is the difference between this and an OEM part?
This is an aftermarket part designed to be functionally identical to the OEM version. It is manufactured to the same dimensional specifications and from comparable materials to ensure equivalent performance and durability, but at a more accessible price.
How often should this part be replaced?
There is no standard replacement interval for this bushing. It is a wear item that should be inspected during any starter service or rebuild and replaced if it shows signs of wear, damage, or excessive play.
OEM vs. Aftermarket?
