Hi,has anyone else had this problem? Whilst doing my usual engine check yesterday on my 84 Turbo, I noticed some small pices of damage to the inner edge (engine side) of the belt.Not on the sprocket side but the outer corner if you see what I mean! There are about four nicks spread over about 6" of belt but not all round.The belt is no where near the edge of the sprocket.The belt is only 6 months old and only done about 2000 miles.I asked Steve at SJ if it could be the belt being too tight but he said no,so the only other thing I can think of is physical damage from the road. Anyone got any other ideas? Needless to say I have ordered a new one!

Cheers Paul.

Could be a number of things mate. A stone or some sort of foreign body got flicked up there. One thing to do is hek to see if the belt moves backwards and forwards on the sprockets while the engine is running and then check it again with someone depressing the clutch.

I had a quarter of an inch tear in mine last year only spotted it when I checked the alternator belt tension. It just so happened to be in line with the alternator at the time. What ever did it was no longer around but I was lucky to spot it.

Strange you mention, but my cambelt has a small chunk out of the outside as well. I can only assume this was damage caused by something travelling through the tensioner with the belt.. It's inevitable when working on the engine, that you lose a nut or something occasionally.

I'm going to change it once the car is able to be driven to my local specialist!

Thanks everyone for your input but the odd thing about my damage is that it not all round the belt so that really rules out rubbing and I have checked and nothing is close to it.Also the there are several little bits missing over a 6" section,it doesnt really look like road damage more like the belt is starting to break up!!! I have booked it in for a belt change and trying not to use it in the meantime, at least I will save on petrol!

Also,pardon my ignorance, Troy, but why should the belt move while depressing the clutch,I havnt checked that yet?

Cheers Paul.

When you press the clutch pedal the release bearing is pushed up against the diaphragm of the clutch assembly. The crank end-float clearance is taken up before the clutch starts to disengage. Now the end-float of the crank should be only a couple of thousandths of an inch and should not affect how your belt runs on the pullies but, if the crank thrust bearing is worn, that is the bearing up against which the crankshaft is pushed when yo put your foot on the clutch pedal, it will move further which could affect the run of the belt. That way it could lokk fine when running normally but not so good with the clutch disengaged.
