Crankshaft Oil Seal Kit for Sea-Doo SP 580
This crankshaft oil seal kit is a direct replacement sealing set for the Sea-Doo SP 580 personal watercraft, built to reseal the crankshaft ends and keep crankcase pressure sealed on the 580 engine.
Overview
This crankshaft oil seal kit is made for the Sea-Doo SP 580, covering the 1989 through 1996 model years. It provides fresh crank seals so the engine stops drawing air or weeping oil past tired seal lips. It suits owners and shops resealing the 580 two-stroke engine in the SP hull.

- Fits the 580 two-stroke engine used in the SP runabout

Good To Know
Q: When should crankshaft oil seals be replaced? A: Replace them any time the engine is apart for a rebuild or when a leak-down test shows the crankcase will not hold pressure. Worn seals can pull air and cause a lean running condition.
Q: Do I need to split the cases to install this kit? A: Crankshaft oil seals sit at the ends of the crank, so installation usually requires removing the engine and opening the case on most two-stroke PWC engines. Have a service manual on hand for torque and reassembly steps.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
