420236501 Timing Chain Tensioner Guide for Sea-Doo RXT X 260 1503 2010-2015

Timing Chain Tensioner Guide for Sea-Doo

This timing chain tensioner guide keeps the timing chain aligned and tensioned on Sea-Doo 1503 engines, and it cross-references OEM part number 420236501.

Overview

This timing chain tensioner guide is a direct-fit replacement component for the 1503 engine used in Sea-Doo RXT and RXT-X 260 watercraft. The tensioner guide maintains proper chain alignment and tension so camshaft timing stays accurate throughout the RPM range. It suits riders performing top-end rebuilds or replacing a worn guide on a 2010-2015 machine.

Specs At A Glance

Good To Know

Q: Does this guide fit both the RXT and RXT-X 260? A: Yes, it is listed for the 1503 engine found in the 2010-2015 RXT and RXT-X 260 models. Confirm your engine displacement before ordering.

Q: Should the tensioner guide be replaced with the chain? A: Replacing the guide alongside the timing chain is common practice during a rebuild to avoid premature wear on new components. Inspect related tensioner parts at the same time.

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