Track Drive Shaft and Chain Case Bearing/Seal Kit for Arctic Cat Bearcat 660

This track drive shaft and chain case bearing and seal kit restores the driveline of your Arctic Cat Bearcat 660, replacing worn bearings and leaking seals in the chain case to keep the track drive turning smoothly through 2003 to 2006 model years.

Overview

Good To Know

Q: Do I need to drain the chain case before installing this kit? A: Yes, the chain case should be drained and the cover removed to access the shaft bearings and seals during installation. Refill with the specified lubricant afterward.

Q: How do I know if my Bearcat 660 needs this kit? A: Noisy or rough rotation at the drive shaft, play in the shaft, or lubricant weeping past the seals all point to worn bearings and seals. Confirm the exact year and model before ordering.

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