Crankshaft Oil Seal Kit for Arctic Cat ZR 580

This crankshaft oil seal kit is a replacement seal set for Arctic Cat ZR 580 snowmobiles built between 1993 and 1997, sized to seal the crank ends on the ZR580 engine and hold crankcase pressure where it belongs.

Overview

This crankshaft oil seal kit fits Arctic Cat ZR 580 models from 1993 through 1997 and is built to seal the crank ends on the ZR580 twin. The crank oil seal kit keeps oil in the case and air out, which is critical on a two-stroke. Anyone rebuilding a ZR 580 bottom end will want this crank oil seal kit on the bench.

Specs At A Glance

Good To Know

Q: Do I need to split the engine case to install these seals? A: On the ZR 580 the crank seals sit behind the case halves, so yes, the case usually has to be split to press them in properly.

Q: Can I run the engine with a leaking crank seal? A: A leaking seal leans out the mixture and can burn a piston, so replace the crank oil seal kit before riding again.

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