Specs At A Glance

Good To Know

Q: What are the signs of a bad crank seal? A: Common signs include oil leaking near the crankcase, hard starting, and a lean condition that will not tune out. A seal leak lets air into the crankcase and upsets the air and fuel mix.

Q: Can these seals be replaced with the engine in the machine? A: Most rebuilds are simpler with the engine removed and split, depending on which side the seal sits. Confirm the procedure for your specific year before starting the job.

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