Good To Know

Q: Do I need to replace this bearing during a top end rebuild? A: It is good practice to replace the wrist pin bearing whenever the piston or rod is serviced, since these small bearings wear with use. Always inspect the wrist pin and connecting rod bore for wear before installing a new bearing.

Q: Will this fit both the EXT 340 and EXT 440? A: This bearing is listed for 1971 Arctic Cat EXT 340 and EXT 440 models running the Kawasaki engine. Confirm your engine and serial number before ordering to be sure of fitment.

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