Crankshaft bearing LEFT for the YAMAHA® PW series (square taper)

This left crankshaft bearing is intended for overhauling Yamaha motors with a square-taper axle and sits on the left-hand side of the housing. The precise groove cut in the outer ring holds the supplied O-ring and reliably seals the motor housing against moisture and dirt – for a smooth, long-lasting drive.

Ready to install & complete

The matching new O-ring is already included: together with the deep-groove ball bearing you get everything for the bearing change on the left-hand side in one set.

Compatibility – motors with square-taper axle
