Good To Know

Q: Will this rim work on my chainsaw? A: This rim is compatible with any saw that uses a 3/8-inch pitch chain and accepts a standard spline drive sprocket rim.

Q: Do I need to replace the clutch drum at the same time? A: No, you only need to replace the rim itself if the drum is in good condition; the rim is separate from the clutch assembly.

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