All about CAMBELTS

Post by Ian_Fearn » Wed Nov 23, 2005 9:11 pm

I want to change the cambelt on my Golf TD and am a bit confused as to exactly how i need to lock the camshaft in place and how i finally tension it.

Does anybody use special tensioning tools or locking tools?

A Turbo XUD with 75BHP? ER NO! Citroen had the sense to give their turbo diesels some grunt!

My son has a gadget he uses on these ricey racers he works on that just locks the cam gears in place that looks like an inch square box section, and then he pins the crank. Slacken tensioners, belt off, belt on, retension, lockers off job done. The only way it can be a problem is if there's an issue as regards the rotation of the tensioners as applies to PSA 16V petrol engines.
Failing that, Anders old trick of marking the old belt with white out and corresponding teeth on pulleys, mark same teeth on new and count the teeth between marks and fit so marks on the sprockets align is as simple as it gets and works every time.

I've never done a cambelt on a Golf [or a BX for that matter] but would the trick work of ........Cutting the belt in half [longways,obviously] ......then removing the half on the outside of the pulleys,putting the new belt half on and then cutting off the last half before sliding the new belt completely on. Dunno if it'd work on a car [BX or Golf or any other] but I've done bike engine cambelts ["Rotax" engines] like so on several occassions.

Jon, what about the final tensioning?

Its described in the Haynes as AAZ, mechanical fuel injection turbocharged.

The marks on the flywheel and engine are there to match up and i understand the part about the camshaft locking now....... BUT

How can i tell if i've got the automatic or manual tensioner?

Is there a spring on the automatic one?

Argh, I've heard scary stories about VAG dealership prices. Like a really scary amount of money just for a back box for a Polo... and if you want to refit the cover over the rear wiper if some batard has nicked it. Ouf.
