Specs At A Glance

Good To Know

Q: How do I know if my crank seals need replacing? A: Rough running, oil weeping at the crank ends, or a fouled plug on one side often point to worn seals. Replacing them during a rebuild is the sure way to rule them out.

Q: Do I need any other parts to install this kit? A: Plan on fresh gaskets for the case covers you open and check the crank bearings while you are in there. Proper installation calls for seating the seals squarely and lubing the lips before assembly.

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