Good To Know

Q: Do I need special tools to install this kit? A: Yes, pressing crank bearings and pulling the crank usually calls for a bearing puller or press along with a crankcase splitter. Q: Can I reuse my old seals? A: No, seals should always be replaced once the crankcase is opened, which is why this kit bundles them with the bearings.

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