TLicense Posted May 24, 2005 Share Posted May 24, 2005 Sometimes on start-up, and occasionally when revving the engine whilst not in gear I get quite a high pitched metallic sounding squeal that lasts very briefly. If it wasn't for how metallic it sounded I woul straight away think belts, but it just doesn't have that rubbery eeeuuuurrrcccchhhh noise. When revving, the squeal stays for as long as I'm accelerating the engine. As soon as I lift off it goes. Other than that drives like normal. Is there anything else, other than belts, that may do something like this? Link to comment Share on other sites More sharing options...
Gordon F Posted May 24, 2005 Share Posted May 24, 2005 Can sometimes be a dry bearing at the front of the power`steering pump. Fire some WD40 in behind the pulley and see if it goes away. Link to comment Share on other sites More sharing options...
absz Posted May 24, 2005 Share Posted May 24, 2005 how about the idler on the belt tensioner Link to comment Share on other sites More sharing options...
Ian C Posted May 24, 2005 Share Posted May 24, 2005 It may actually be a slipping belt... Just early stages of it, i.e. it only manifests when the belt has to accelerate all the pullies. Fancy seeing you here absxxxx, I just mentioned your name in another thread -Ian Link to comment Share on other sites More sharing options...
Jake Posted May 24, 2005 Share Posted May 24, 2005 I had a very similar sounding problem to that, Tony. It turned out that the crank pulley had sheared. Most of the time it was going around ok because of the friction between the centre of the pulley and the outer ring. Obviously it was only when it was slipping that it made the squealing noise.

Jake Posted May 24, 2005 Share Posted May 24, 2005 There is always that, Mr Grim Reaper Changing the crank pulley is no biggie, is it? Unless you're unlucky enough for the damn thing to fall off. I bet that's messy! Link to comment Share on other sites More sharing options...
Ian C Posted May 24, 2005 Share Posted May 24, 2005 Well, I've done mine twice, it's a biggish job as you should take out the rad, and it needs a specialist service tool - a HiLift jack handle Plus a decent impact socket for the nut and a real good T-bar for the jack handle to go over. Manual gearboxes are great, stick 'em in 1st and get someone to stand on the brakes as you hang off the end of the jack handle. An accessory drive belt is still easier though. -Ian Link to comment Share on other sites More sharing options...

womble Posted May 24, 2005 Share Posted May 24, 2005 Changing the crank pulley is no biggie, is it? Unless you're unlucky enough for the damn thing to fall off. I bet that's messy! The outer ring came off mine and judging by the state of it when I discovered it upon my undertray (imagine my shock / perplexment !!) it had been off for quite a while, the belt had worn groves into the rubber of the remaining inner, how it didn't come off when the inner shed the outer I'll never know Link to comment Share on other sites More sharing options...
TLicense Posted May 26, 2005 Author Share Posted May 26, 2005 Right, Just had a good peer around, and yup, my rings split. When I've got the air-con on and rev the car the lower pulley goes for a wobbler. Not good. The good news is it only does this when there's that extra bit of loading on the pulley, and it seems to be fine under all other conditions... but then it's just a matter of time until it goes Pete... Soooo, the car's going to quality repaints on Tuesday, so hopefully I can sort something out. Link to comment Share on other sites More sharing options...
Jake Posted May 26, 2005 Share Posted May 26, 2005 Ah well. Good job you found it before something nasty happened. Link to comment Share on other sites More sharing options...
TLicense Posted June 3, 2005 Author Share Posted June 3, 2005 OK so the car's currently being re-sprayed, which means I've got a few weeks before this becomes an issue again. I'm struggling to find someone who is a)willing and b)competant enough to do the job. This may mean I have to do it myself. So, in terms of parts, just the lower pulley yeah? The accessory belt is only a year old so maybe not worth bothering. Now does this pulley carry the cambelt, or is that seperate? If it does I'll replace the cambelt at the same time. Is it a nut or a bolt that holds it on? I'll probably get replacement for that anyway as it's bound to get buggered when it's being taken off. Any other suggestions?

Ian C Posted June 3, 2005 Share Posted June 3, 2005 Wow, Jake the angel of death stuck home Glad you spotted this early and didn't listen to me The cambelt runs off a cog behind the crank pulley so it's left alone -Ian Link to comment Share on other sites More sharing options...
b_have Posted June 3, 2005 Share Posted June 3, 2005 Tony, Its a large (22mm head) bolt that is torqued to about 240 lb/ft. Can be tricky to crack loose but don't use heat as you are close to the cambelt and front crankseal. I made my own SST to hold the pulley and another to pull it off the crank. You will need a BIG torque wrench to refit. Link to comment Share on other sites More sharing options...
TLicense Posted June 7, 2005 Author Share Posted June 7, 2005 Cheers boys, So Belt off, impact wrench the nut off, pulley off, new pulley on, torque the new nut up, belt back on, tea time yeah? Doesn't sound particularly trick. What's the bother then? Is the problem just getting the nut off? Link to comment Share on other sites More sharing options...
Ian C Posted June 7, 2005 Share Posted June 7, 2005 You could say that, yes You might want to remove the radiator - more hassle and mess in the short term, but beats having to replace it if the impact socket slips off at full gngngngng power. The difficult bit is winding up the slack even with a manual. How the auto boys do it is beyond me -Ian Link to comment Share on other sites More sharing options...
womble Posted June 7, 2005 Share Posted June 7, 2005 Just spoken to the gut that did mine a few months ago and whilst the nut is quite tricky to get off due to space limitations the hardest bit by far was removing the pully which had seized on. As mentioned earlier do not be tempted to use heat as this can easilly damage the oil seal that sits buhind it. Link to comment Share on other sites More sharing options...
Ian C Posted June 7, 2005 Share Posted June 7, 2005 A pulley remover should be used to take the pulley off, and a handy hint is to put an expendable bolt into the bolt hole for the pulley to press against, as it will dig a divot out of it -Ian Link to comment Share on other sites More sharing options...

absz Posted June 7, 2005 Share Posted June 7, 2005 Ahh tricks of the trade eh guys, tricks of the trade. Cheers, no tricks i normally do it the long way, but its much easier. all you need is a 2 poster hoist. a workshop heavy duty compressor,1"1/4 drive commercial air gun, and a aircon re-gas system as i remove both coolant and aircon rads to allow for work space for the huge air gun i use. and not forgetting the pulley removal set. its just to easy my way Link to comment Share on other sites More sharing options...
