Replacement Cam Chain Tensioner Spring complete with copper sealing washer. It is recommended that the spring is replaced if its length has reduced significantly below 73.7mm. This is a much more cost effective option than replacing the complete tensioner assembly. Replacement of the spring requires only the 19mm hexagon headed bolt to be removed and the spring can then be replaced. A very simple job.
