PRODUCT DETAILS:
This crankshaft repair sleeve is designed for Yamaha 500cc personal watercraft engines including the Wave Jammer 500 from 1987 through 1990 and the Wave Runner 500 from 1987 through 1993. The repair sleeve restores the crankshaft oil seal surface area that becomes worn or grooved over time from normal seal contact and rotation, eliminating the need to replace the entire crankshaft assembly. A worn crankshaft seal journal will allow oil to leak past the seal lip, which in a 2-stroke personal watercraft engine can cause loss of crankcase pressure, poor performance, and potential engine damage. The precision-machined sleeve presses onto the crankshaft at the oil seal contact area to provide a fresh smooth sealing surface for the new oil seal during engine rebuild. The Yamaha Wave Jammer and Wave Runner 500 models are popular vintage personal watercraft that benefit from this cost-effective crankshaft repair solution during engine rebuild. Installing a crank repair sleeve during engine rebuild is significantly more affordable than replacing the entire crankshaft when the only damage is at the seal journal surface. Always use a new oil seal when installing the repair sleeve to ensure proper sealing between the new sleeve surface and the fresh seal lip. Verify your engine model before ordering to confirm correct application for your specific watercraft.
