Product Description The RLG00009/C Tensioner is a critical “set-and-forget” component that automatically adjusts as the timing chain stretches over time. In the newer J-Series engines found in the Hunter 350, this tensioner prevents the “ticking” or “clattering” noise often associated with a loose timing chain. The suffix “/C” denotes the latest technical revision, which features an improved internal spring and ratcheting mechanism to prevent “back-slippage,” a common cause of timing noise in earlier production batches. As a genuine OEM part, it is built to handle the high thermal cycles of the long-stroke engine while maintaining consistent pressure on the chain guide. Key Features: Automatic Adjustment: Eliminates the need for manual timing chain tensioning throughout the life of the chain. Latest Revision (/C): Features reinforced internal components to ensure silent engine operation and long-term durability. Oil-Pressure Assisted: Works in tandem with the engine’s oil pressure to provide dynamic tensioning during high RPMs. Anti-Kickback Mechanism: The ratcheting design ensures the tensioner only moves forward, preventing chain slack during engine shutdown or kickback. OEM Reliability: 100% original Royal Enfield part, ensuring perfect bolt-on fitment and timing accuracy.
