Manual cam chain tensioner with constant tension Function and benefit: Maintains constant cam chain tension to address the limitations of automatic and hydraulic tensioners, keeping timing stable across operating conditions. Why customers need it: Prevents timing drift caused by backout or slippage of automatic tensioners when the throttle is closed suddenly at RPM, reducing the risk of timing misalignment. Key advantages: Consistent tension independent of throttle input Reduces the possibility of cams going out of time Helps prevent bent valves and potential engine damage Compatibility and usage: Designed to or upgrade standard cam chain tensioner systems in engines that use a manual tensioner; verify compatibility with your engine model and installation requirements. Material and build: Aluminum alloy construction for strength, durability, and lighter weight. Performance attributes: Reliable, steady tension across RPM ranges, contributing to improved timing stability and engine longevity. Design notes: Compact aluminum alloy design that supports durable, longterm operation. Use scenarios and applications: 1) Track or performance riding where rapid throttle changes occur, requiring stable timing. 2) Engines with a history of timing chain tensioner backout or slippage, to reduce risk of valve damage. 3) Engine rebuilds or performance upgrades where a reliable manual tensioner improves timing consistency and overall reliability.
