Specs At A Glance

Good To Know

Q: Is this an original Kawasaki part? A: This is an aftermarket replacement seal that cross-references OEM number 92049-3737, and it is not manufactured by Kawasaki. Always confirm the part number matches your machine before ordering.

Q: Can I reuse my old seal during reassembly? A: Oil seals should be replaced any time the crankcase is opened or the crankshaft is serviced. Reusing a worn seal risks oil leaks and water intrusion that can damage the engine.

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