Specs At A Glance

Good To Know

Q: Why do crank seals need replacing? A: Over time the rubber hardens and the sealing lip loses tension, letting oil escape and air enter the crankcase. New seals restore proper sealing and reliable engine operation.

Q: Is this an original Kawasaki part? A: No, this is an aftermarket crankshaft oil seal kit designed to fit the listed Kawasaki Drifter 340 Fan models. Always compare dimensions to the seals being removed before installation.

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