Tension reliever manual primary chain adjuster
Twin Power continues to add to their growing line of aftermarket parts and accessories for V-twin motorcycles. The newest addition is this tension reliever manual primary chain adjuster, designed to eliminate previous issues with keeping the primary chain at the right tension.
“An overtightened primary chain is known to cause premature failure of the engine, transmission and primary bearing as well as to cause other complications,” says James Simonelli, Brand Manager for Twin Power. “This problem plagues 2006 Dyna and 2007 and later Big Twin models. These motorcycles came equipped with an automatic ratcheting primary chain tensioner, which is the culprit.”
Twin Power has developed a solution, which keeps the problem of overtightening from occurring. It replaces the stock factory adjuster, allowing a proper primary chain adjustment of 5/8–7/8 inches of free play when cold. It is machined from 6061-T6 aluminum and hard anodized for durability.
It also features a 4140 steel adjusting screw and heavy-duty nylon 6/6 shoe. 100% made in USA and easy to adjust, it uses stock mounting hardware. For use with 34-tooth sprockets; the chain adjustment and tension check will require the removal of the outer primary cover.
