Crankshaft / Crank Oil Seal Kit for Ski-Doo

This crankshaft / crank oil seal kit is a replacement seal set designed to reseal the crank ends on 700-series Ski-Doo snowmobile engines, restoring proper sealing between the crankcase and the outer engine components.

Good To Know

Q: Why do crank seals matter on a two-stroke? A: Leaking crank seals let air into the crankcase and cause lean running, poor idle, or even piston damage. Replacing them when you service the crank keeps the engine sealed properly.

Q: Are these seals reusable? A: No, crank seals are wear items and should be replaced any time the crank is out or a leak is found. This kit supplies the seals for the job in one set.

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