cam belt help

My twinnie is supposed to have had a belt & tensioner change 6K-ish miles ago (just before I bought it)...there is a receipt from some east-end 'specialist', but looking through the gap in the cam-belt cover and turning the engine over slowly I can't see any writing on the belt anywhere...would have thought this should still be visible after only 6-8K miles. On this basis (unless anyone can tell me how to check the condition of the belt and tensioners easily) I am assuming that it wasn't really done. How big a job is it for the reasonably competent home mechanic....do I need a dial gauge to get TDC, is there any other issues I need to look out for. I've looked at the workshop manual CD and various websites that detail how to do it step by step, but was looking for any real life experience of how to make it simple. Local independents quote between £300-450, and as I suspect most of that is labour I'm hoping it's something I can tackle myself

Re: cam belt help

best real life experience is here

camlocks are a must, dial gauge I guess can be done without, but useful to have if not got one already. Should be easier on a 166 as the engine looks tiny in there, on a a 145 it fills the bay. Camlocks can be got off ebay or loaned from eb spares if you get the bits of them IIRC

Re: cam belt help

You'll also need the adaptor for the dial gauge that screws into No1 plug hole, unless you make up some sort of bracket and extension to the plunger yourself.

Re: cam belt help

We do the job regally and the reason the labor is so expensive, and I do agree is, is that it is a horrible time consuming job, donít get it done on the cheap. Cam locking tools must be used (tipex marks on the covers show the job has been bodged), the adapter and a dial gauge are required.

By the time you have bought to tools etc you may as well get some one to do it for you.

However if you have been sold the car with these jobs done you should go back to the people you bought the car from.

Re: cam belt help

unfortunately the car was bought privately. The guy had had a replacement engine fitted and the supplier who fitted it (some alfa breaker in Camberwell) gives a receipt saying "changed oil, belts (cam & tensioner)". Looks genuine enough, but not very detailed, ie does that mean the cam and tensioner belts or the cam and tensioners?...I suspect that I'll get little re-dress from trying to chase them up!

Re: cam belt help

changing the belts is not really that tricky on the 166 twink (easy enoguh that even i can manage it!)....cam locks will set you back about 20 squid (you can borrow mine if i can find them!), dial gauge about 20 squid (again, i've got one kicking about somewhere) and the parts will set you back about 70 quid IIRC. Set aside a saturday and take your time....trickiest bit i found was getting the wee nut back on the back of the balance belt tensioner!

That is a very kind offer.
