Crankshaft Main Bearing for Sea-Doo

This crankshaft main bearing is a replacement engine component that supports the crankshaft inside the 1503 engine used in the Sea-Doo GTX LTD 230, helping maintain smooth rotation and proper oil clearance under load.

Overview

This crankshaft main bearing is built to replace a worn or scored bearing in the 1503 engine found in the Sea-Doo GTX LTD 230. It supports the crankshaft journal so the rotating assembly stays true at high RPM, which helps reduce vibration and protect the crank from excess wear. It suits riders and mechanics rebuilding or refreshing these 2017 to 2019 watercraft.

Good To Know

Q: Can I install this bearing without splitting the crankcase? A: No, crankshaft main bearings sit inside the crankcase, so the engine must be disassembled for replacement. Proper torque and clearance checks are needed during reassembly.

Q: Should I replace all main bearings at once? A: When one main bearing shows wear, the others usually share the same hours and often need replacement too. Inspect all journals and bearings before ordering just one.

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