Crankshaft / Crank Oil Seal Kit for Polaris Indy XC 440

This crankshaft and crank oil seal kit is a direct-fit replacement set for the Polaris Indy XC 440, restoring the critical crankcase seal that keeps oil where it belongs and contamination out of the bottom end.

Specs At A Glance

Good To Know

Q: Do I need to split the cases to install these seals? A: On most Polaris twin engines, crank seals can be replaced by removing the clutch and ignition side covers, though full case splitting may be required depending on the seal location.

Q: Why replace crank seals on an older Indy? A: Worn seals let air into the crankcase and cause lean conditions, erratic idle, and possible piston damage, so replacing them during a rebuild protects the engine.

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