Crankshaft Main Bearing for Sea-Doo GTR 215 1503

This crankshaft main bearing is a precision engine component built to support the crankshaft in Sea-Doo GTR 215 1503 models from 2012 through 2016, helping maintain stable rotation and proper oil clearance under load.

Overview

This crankshaft main bearing is manufactured to serve as a direct replacement for the bearing surfaces that carry the crankshaft inside the 1503 engine platform. It helps control radial and axial movement of the crank, which keeps the rotating assembly aligned at high RPM. Developed for riders and mechanics servicing Sea-Doo GTR 215 machines who need a dependable crankshaft main bearing rather than a compromised original.

Good To Know

Q: How many main bearings does this listing include? A: This listing covers one crankshaft main bearing, so confirm the quantity required for your rebuild before ordering.

Q: Should main bearings be replaced as a set? A: Most engine builders replace all crankshaft main bearings together during a rebuild to keep oil clearance consistent across every journal.

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