Specs At A Glance

Good To Know

Q: How can I tell the lower chain case bearing is failing? A: Grinding, growling, or roughness when the shaft turns often points to a worn bearing. Inspect the races and seals once the chain case cover is off.

Q: Is this an original Arctic Cat part? A: This is an aftermarket bearing made to fit Arctic Cat models and cross-references OEM number 1702-179. It is not an original Arctic Cat product.

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