Good To Know

Q: Why replace the crank seals? A: Worn crank seals let air leak into the crankcase, which leans the mix and causes poor running. New seals restore the seal the engine needs.

Q: Do I need any special tools? A: Seal installation on these vintage engines typically calls for a seal driver or careful pressing. Check your service manual for the correct procedure.

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