Lost the old belt whilst driving. ONes bought matched for engine were very long, and made constant rubbing. so bought shorter ones, and no just rubs on full lock as mentioned

Well unless the new belt is longer than the old one, It is just coincidence

Normally yes, I'd agree with you. Just seems huge co incidence no issues until change belt and on first drive it rubs

Mounts have worn, The rubber has gone squshy, Its why you haven't had any issue until now. The engine is moving around.

This is assuming there isn't a bolt lose on one of the mounts or something.

First mount I'd check would be the drivers side chassis leg one, Then the two gearbox ones (under car and on the passenger leg)

Oh and this isn't checking into corners, this is full lock at about 10mph

How many mounts are there mate? 2? I take it the other on is tucked away under the inlet area?

being honest here, my alternator is quite close to the body of the car and ive thrown it into corners and its never had a problem. check all the mounts are properly tight as it should have some movement but yours might be moving a bit too much

Not looked how its held on mate, played about with otherside for long enouggh, but never rmeoved it to see the otherside.

Would be one way around it then,there's alot of play in the alternator its self, I'm not sure whats normal, but easily moves from side to side

i had a similar problem, solution was to grind a bit off the back of the alternator mount which brought it closer

Just not sure why I only have this problem now? Literally nothing before in the last 6 months of driving this xe

I had four ribs on my Alternator pulley, I've found the M-TEC engine mount gives the most clearance away from the chassie.

Happened to me when I had a multi v belt engine, only thing that I ever thought would sort it is either cutting a couple of ribs off the pulley and getting a slimmer belt or fitting v belt pulleys. Pain in the arse either way

Belt broke last week, so bought new one. With new one fitted pulley was grinding on chassis leg.


So I bought a smaller belt, to bring alternator forward a bit, now idles fine but with any cornering it's hitting the chassis.


Anyone have ideas? Have adjusted alternator pulley as much as I could when I was fitting the belt
