Question about belt tensioner pulley

hugo_nz · 03-04-2019, 05:29 PM

Hi folks,

Quick Q: has anyone replaced the tensioner pulley? Is it possible to replace the pulley on it's own or does the entire tensioner assembly have to be replaced? Mine is making a lovely chirping noise...

You have to buy whole tensioner assembly($60). You can do it yourself and you can also replace the belt and iddler pulley. and check for leaks from OFH.
