Good To Know

Q: Does this seal fit original Kawasaki crankshafts? A: This aftermarket seal is designed to match OEM dimensions for the 1500 engine platform. It is not an original Kawasaki part but is made for direct replacement fitment.

Q: Can I install this without splitting the crankcase? A: Seal replacement generally requires access to the PTO inner area, and on most 1500 engines this means partial disassembly. Consult a service manual for the correct procedure.

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