B25 Primary chain tensioner
« on: 26 March, 2019, 18:08:05 »
I have a worn primary chain tensioner on a B25SS, I have ground down the chain wear grooves and have it nice and smooth again with about 1 mm taken off and 1.5mm still there, so my question is:- does anyone know if this ok to use or would the original top surface have been hardened and this is now on softer metal.
Thanks in advance.
