Good To Know

Q: How do I know if this bearing needs replacing? A: Grinding noises, oil weeping from the chain case, or play in the driveshaft usually point to a worn bearing and seal. Replacing both together is the standard fix.

Q: Will this fit other Arctic Cat models? A: This kit is listed for the 2003 Mountain Cat 900, so confirm your model year and driveline layout before ordering.
