PRODUCT DETAILS:
Direct replacement crankshaft main bearing for the magneto side of Yamaha 500cc personal watercraft engines covering the Wave Jammer 500 from 1987 through 1990 and the Wave Runner 500 from 1987 through 1993. This deep groove ball bearing replaces the original MAG side crankshaft bearing in Yamaha 500cc 2-stroke engines where the magneto flywheel assembly mounts to the crankshaft output. Manufactured to specifications for proper fit and long service life in the demanding marine environment where saltwater and high RPM create extreme bearing loads. The crankshaft main bearing at the magneto position is critical for maintaining correct crankshaft alignment and proper magneto air gap for reliable ignition timing. Yamaha Wave Jammer 500 and Wave Runner 500 models were among the original mass-produced personal watercraft and their 500cc 2-stroke engines are popular for restoration and continued use. Always replace crankshaft bearings during engine rebuild to prevent premature failure from worn bearings that can lead to crankshaft damage and total engine failure. Confirm your engine model and part number before purchasing to verify proper fitment.
