Good To Know

Q: How do I know if my jackshaft bearings need replacing? A: Grinding noise, vibration, or rough rotation from the chain case area usually points to worn jackshaft bearings. Inspecting the bearings and seals during chain case service helps catch wear before it damages the shaft.

Q: Should bearings and seals be replaced at the same time? A: Yes, replacing the bearings and seals together in one service job saves labor and helps prevent leaks that would otherwise require reopening the chain case. This kit provides both so the job can be completed in one pass.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
