Crankshaft Crank Oil Seal Kit for Ski-Doo Legend 800 2003

Crankshaft / Crank Oil Seal Kit for Ski-Doo

This crankshaft and crank oil seal kit is a direct replacement sealing set built to keep oil where it belongs on 800cc Ski-Doo snowmobile engines, and it installs in the same location as the factory seals it replaces.

Overview

This crankshaft / crank oil seal kit is made for riders rebuilding or resealing the lower end of an 800cc Ski-Doo engine. The seals in this kit hold crankcase pressure and keep oil from migrating past the crankshaft bearings, which protects the bearings and keeps the engine running clean. It is aimed at DIY rebuilders and shops servicing high-mileage 800 series twin engines.

Built For Performance

• Seals the crankshaft ends to maintain proper crankcase pressure
• Keeps oil contained at the crank bearings to prevent lean-running air leaks
• Direct-fit dimensions for 800cc Ski-Doo crank applications
• Oil-resistant seal material suited to two-stroke engine heat and vibration
• Kit form includes the seals needed for a full crankshaft reseal job

Fits These Machines

• for Ski-Doo Legend 800 (2003)

On-The-Job Use

• Crankcase reseal during a bottom end rebuild
• Replacing leaking crank seals on a high-mileage 800 engine
• Routine lower end service on trail and utility sleds
• Shop repair of oil migration or pressure loss issues

Specs At A Glance

Good To Know

Q: Do I need to split the crankcase to install these seals? A: On most 800 Ski-Doo engines the crank seals sit at the outer ends of the crankshaft, but access depends on the specific engine layout, so confirm the procedure for your model before starting.

Q: How do I know the crank seals need replacing? A: Common signs include oil loss, erratic idle, hard starting, or a lean-running condition from air being drawn past worn seals.

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