Easy to apply excessive belt tension with the VW type of tensioners. When I replaced the belt on my 924 long ago. I made the belt too tight and it was screaming. Even the cam was making a sound.

I used VWs belt tension recommendation which was to turn the belt 90 degrees. I thought it had to be hard to turn but they want it rather easy to turn to check tension.

What a mess.. 2 things from my experience.. The thing with overtightening the belt is a bit a miracle.. It is just a bit while tightening and then you need to turn the engine over two times to check tension.. I ****ed 2 bearings with an overtightened belt and you will hear the bearings scream and get very hot if it's too tight.. Also I had to machine down the yoshifab tensioner plate one millimeter to make the belt run in the middle of the tensioner pulley cause mine started also to eat out the belts rim..

Missed your replies.

So far there has been zero damage to the belt itself with the tensioner barely tensioned. Guess the spring-loaded mechanism doesn't do much.

To wit, I do not like the way the belt rides at the moment. Machining down the tensioner side 1mm seems like a good idea. I'll have that done the next time the engine is apart.
