Club 80-90 Forums

Having just suffered a cam belt tensioner failure, resulting in cam belt losing its teeth and piston/valve contact, bent valves etc. I am about to fit a replacement cylinder head assembly.

Can anyone advise how tight the new cam belt should be, is there a tool for tensioning it and measuring the tension ?

cheers

Found this BUT it just might make your head explode after you have read it a couple of times,,,,,,

I have allways worked to the rule of:-

"when you can just twist the bet through 90 degrees along it's longest run thats about right"

I have never had a belt fail on me after using that (that includes Ducati's using Renault clio cambelts too!!)

I use the 90 degree rule on fan/alt belts... never had a belt fail..

My engine uses the newer style pulley which has the tension indicator built in. You could use possibly use one on your engine or just have a tweak on my belt to see if they feel about the same.

I should have mentioned it's when you can just twist it using only your finger and thumb not your whole hand/pair of pliers/other!

Thanks for all the advice,
head is on all ancillaries fitted.
