I had my cam belt, water pump and roller/tensioners replaced yesterday. The mechanic told me that the rubber seal on the cam belt pully located on the crank is split, will fail soon and cause the belt to slip, etc, etc.
I haven't lhad a chance to look at this and the haynes manual doesn't show any pics of it. Is there a rubber seal that could cause this? Seems a crappy way to design an engine and I don't feel llike giving him another £200
The way this guy was talking, it sounded like the cam belt pulley was built like a harmonic balancer. I would expect it to be a solid chunk of metal that slips onto the crank and is held in place by a key. Granted the only engines I have worked on are ford and chevy v8's and they have timing chains intead of belts.
i dont remember any rubber ring between my crank pulley and the crank sprocket. I may be proven otherwise but i WOULD have noticed cause it took me about 3 hours to manhandle those bunch of arse vauxhall spline bolts from the crank pulley.
The pulley is one part even though its has technically got two pulleys together. and it does join to the crank sprocket with opffset holes, yes, so it can only go on one way.
