FAQ 

1. Can the pivot be reused with light scratches on journal surface?
Minor scratches can be polished for reuse. Replace it immediately if scuffing, step wear or bending occurs.

2. Is 158-3416 interchangeable with 151-5966?
No. They differ in shaft diameter, length and locating shoulder, designed for different gear housing versions.

3. Why does the new pivot wear out quickly after replacement?
It is usually caused by blocked oil passages, excessive bushing clearance or misaligned gear mesh. Only replacing the pivot without repairing mating parts will lead to repeated failure.

4. Does it fit both generator and construction machine versions?
It works for the same engine model. Verify engine nameplate and gear housing drawing before ordering.
