Re: Caledonia Preston
It appears that when they changed the cambelt and tensioners at its 72000 mile service last year they had to remove the auxiliary belt and tensioners etc to gain access. when they put it all back together there is pretty strong evidence that they re-installed the top auxiliary pulley with the mounting bolt cross threaded, hence the pulley was at an acute angle compared with the rest of the auxiliary pulleys. there are also marks on the bolt head that appear to suggest that rather than use a spanner or socket, it was done with an air driven type wrench. like the ones that are used by tyre fitters. The bolt was found sheared and hanging on by a few threads. As a result, the car has shredded 4 auxiliary belts because the top pulley was trying to force the belt over due to it being at an angle of 2-3 degrees.
There is also evidence that the crankshaft auxiliary pulley had not been installed correctly and this has had to be replaced; as well as the large aluminium bracket that bolts on to the side of the engine and hold the cam belt tensioner, alternator, power steering pump etc. Both auxiliary tensioners also had to be replaced.
I am so grateful that I discovered Heath Road Garage in Sandbach, even though it is a 30 mile trip there for me. They are extremely competent and give the customer a lot of confidence.
