In stock IN STOCK


Automatic timing chain tensioner for Moto Guzzi big twins with timing chains. Spring loaded tensioner has a large blade which applies steady pressure to the chain, resulting in less chain whip and more accurate cam and ignition timing. This unit has been given many different names over the years.

Helpful tips: Unit mounts to the front main bearing retaining bolts, it only fits one way; a third hand is helpful during installation but not required; the upper end of the plastic blade rests against the inside of timing chest; snug up the lock nut on the pivot prior to operation; finally, there is no need to plug the holes left by the original tensioning device.

These automatic tensioners have been on the global market for several decades now and are known to perform reliably in excess of 100,000 miles. Can be used as a replacement for original Guzzi automatic tensioner, part number 30057810.
