MUDDY DOUGLAS Posted July 29, 2007 Share Posted July 29, 2007 I have just put on a new aux belt onto my disco. Travelled about 200yds and it was all chewed up. Any ideas as to what I did wrong Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted July 29, 2007 Share Posted July 29, 2007 I reckon you didn't check that the belt was correctly on all the pulleys. One more point, if you changed it - why? If the old one was broken you may have a siezed tensioner bearing which will chew up any belt you fit. Though it will normally take more than 200 yds.

BogMonster Posted July 29, 2007 Share Posted July 29, 2007 The alternator bearing can also seize, though usually you can't start the engine if that happens! Quote Link to comment Share on other sites More sharing options...
MUDDY DOUGLAS Posted July 29, 2007 Author Share Posted July 29, 2007 The alternator bearing can also seize, though usually you can't start the engine if that happens! I have recently had a new alternator, bearings on that are fine, also have had new tensioner also bearings ok. I have ordered a new belt for 2morrow but the guy in the shop said I may have fitted against the directionof travel. I will check next time to see if the belt has any arrows. I am a new member and think this is a great site.thankyou everyone Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted July 30, 2007 Share Posted July 30, 2007 Fitted against the direction of travel? Since when are these belts directional? Really, some of the idiots the have in shops nowadays. Quote Link to comment Share on other sites More sharing options...

I wasn't aware of the belts being directional either and AFAIK there are no arrows on them... But I will have a look later just to be sure Quote Link to comment Share on other sites More sharing options...

Might be worth checking to see if all the pulleys are aligned. Where did you get the new alternator and is it a genuine or pattern one?

MUDDY DOUGLAS Posted August 3, 2007 Author Share Posted August 3, 2007 Cheers Countax Yeah looks as though ther is a 1mm disalignment on the alternator. Filed same off mounting bracket and its sorted Cheers Charlie Quote Link to comment Share on other sites More sharing options...
Roverdrive Posted August 3, 2007 Share Posted August 3, 2007 IMHO a misalignment of 2mm is FA! M8s alternator sits on an angle compared to the other pulleys without any problem. Mine is not as bad, but can't be considered either straight or in line, and has had the same belt for the last 3 years or so. Certainly more than 200 yrds worth! There may well be a direction in which the belts are laaid during construction, but I have never come across instructions for directional fitting. BTW are we talking of V belts or serpentine? Knew I shouldn't have had that last beer or three. Quote Link to comment Share on other sites More sharing options...

Roverdrive Posted August 4, 2007 Share Posted August 4, 2007 Yes by the time I had engaged the dog clutch driving the brain, there had been FAR too much typing to delete, especially at the speed I type. Think the bottle of red after the beer might have had something to do with it. If it is serptentine, then something is out of line as you say.
