Review Rating: Sort By:

Reviewed on

This is an interesting part. It is very soft steel, and subject to bending. I bent the original by backing out the adjuster screw too far, then tightened it against the gear. Bad. the new part was perfectly straight, and worked wonderfully upon installation. Installation meant splitting the crankcase, but not as big a deal as one might think.
