Crankshaft Main Bearing for Sea-Doo RXT 260

This crankshaft main bearing is a replacement engine component for the Sea-Doo RXT 260 1503, built to support the crankshaft and keep rotation true under load.

Overview

This crankshaft main bearing is made for the Sea-Doo RXT 260 1503 and serves as a load-bearing surface that keeps the crankshaft spinning on axis inside the engine cases.

Good To Know

Q: How many main bearings does my engine need? A: The count depends on your specific crankshaft layout and service manual, so verify the required quantity before ordering. Many rebuilds replace all main bearings together as a set.

Q: Can I install this without splitting the cases? A: No, main bearing replacement on this engine requires case separation and careful measurement of clearances. Have a qualified mechanic handle the installation and torque specs.

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