Good To Know

Q: Do I need to split the cases to install these seals? A: On the 1999 Summit 600 the crank seals sit at the outer ends of the crankshaft, so they can often be replaced without splitting the cases, though case-splitting is required on some rebuilds. A: Confirm the seal position for your specific engine before starting the job.

Q: How do I know the crank seals need replacing? A: Common signs are oil weeping at the crank ends, poor idle, lean running, or a crankcase that will not hold pressure during a leak-down test. A: A leak-down test is the most reliable way to confirm the seals are the cause.

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