SPendrey Posted May 30, 2012 Share Posted May 30, 2012 Hello, Last week the Aircon made a lovely squealing noise, but only for a few seconds, then went quiet. The next day the belt gave up and took the auxiliary belt with it! No problem as I always carry a spare aux belt. Anyway, to the point... I bought 2 x ERR2215R (Bearmach) replacement A/C belts only to find they're so tight to fit that I gave up! They are 4PK1322, which looks like the correct length according to a few sites, but it is shorter than the original on my '95 300TDi. So, any idea why the shorter length is used? Also any idea what the original length was, the old belt is so shredded there we no markings to be found. Thanks, Scott Quote Link to comment Share on other sites More sharing options...
Boydie Posted May 30, 2012 Share Posted May 30, 2012 Silly question but have you fully loosened the A/C belt tensioner? The three bolts need to be fully backed off before the new belt will fit, and yes, if the A/C belt goes it invariably takes the main belt with it, when mine went it also tore out the cables to the electro-magnetic clutch causing me expecnce to buy a second hand compressor Quote Link to comment Share on other sites More sharing options...
SPendrey Posted May 31, 2012 Author Share Posted May 31, 2012 Yep, tensioner is out of the equation. That's one of the odd things though, it almost looks like the 'replacement' belt eliminates the need for a tensioner because it's so tight!

Niamh Posted May 31, 2012 Share Posted May 31, 2012 2 x ERR2215R (Bearmach) replacement A/C belts only to find they're so tight to fit that I gave up! They are 4PK1322 Well I've looked at the one in our stock drawer, ans it's an ERR2215 marked 4pk1325 Niamh Quote Link to comment Share on other sites More sharing options...
SPendrey Posted May 31, 2012 Author Share Posted May 31, 2012 Thanks Niamm, I guess the 3mm isn't going to make much difference, but maybe just enough to pop over the edges of the pulley. Anyway, still much shorter than the previous belt on there. Cheers. Quote Link to comment Share on other sites More sharing options...
Niamh Posted May 31, 2012 Share Posted May 31, 2012 How would your length bee without the idler pulley? Niamh Quote Link to comment Share on other sites More sharing options...
SPendrey Posted May 31, 2012 Author Share Posted May 31, 2012 Which is the idler pulley? The 1322 length would fit without slack if I could only get it over the edges of the pulleys! I found out the Australian spec Disco uses a 1360 length belt, so I'm going to get one of those and allow the tensioner to take up the slack. No idea why the normal belt doesn't fit, but there we go!

Disco1tdi Posted May 31, 2012 Share Posted May 31, 2012 Are you sure that you've taken the right route, with the belt? Mine's got loads of deflection around the tensioner. (It's a 1322 belt) Quote Link to comment Share on other sites More sharing options...

Boydie Posted June 1, 2012 Share Posted June 1, 2012 Thats a thought - are you trying to route the belt outside the idler pulley, it goes on the inside. Quote Link to comment Share on other sites More sharing options...

Disco1tdi Posted June 1, 2012 Share Posted June 1, 2012 That's a relief... I was braced for being told mine was on, all wrong... :-) Quote Link to comment Share on other sites More sharing options...
SPendrey Posted June 4, 2012 Author Share Posted June 4, 2012 A pic, if it helps?.... Mine is just like yours... except mine has a hand trying to show the belt being just a little bit short! Quote Link to comment Share on other sites More sharing options...
SPendrey Posted June 4, 2012 Author Share Posted June 4, 2012 Anyway, the aircon will take a back seat now as the head gasket went this weekend! :-( Quote Link to comment Share on other sites More sharing options...
Boydie Posted June 6, 2012 Share Posted June 6, 2012 It doesnt look short, it is supposed to go there and the idler presses against it -- check out the diagram Quote Link to comment Share on other sites More sharing options...
SPendrey Posted June 6, 2012 Author Share Posted June 6, 2012 Which is why I pose the problem... I just can't get the belt over the edges (the raised lips if you like?) of any of the pulleys when it is in placed on all the others. It certainly sounds like 1322 is the right length, so maybe there's a 'technique' for getting it over that last edge and onto the pulley. I may also look for a 1330 (or something similar) to resolve the issue and use the tensioner to take up the slack. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted June 6, 2012 Share Posted June 6, 2012 I've not tried an aircon belt, however when fitting tight belts I put it onto the largest pulley last (although for convenience I would in this case put it over the aircon pulley last). Once belt is around all other pulleys get it as far around the last pulley as you can and then turn the pulley (and mpossibly the engine) and it should pull itself on. This might work for you, apologies if you have already tried this. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted June 6, 2012 Share Posted June 6, 2012 .... you could also try removing the idler pulley, put the belt in place, then put the idler pulley back on with the belt already around it .... there should be enough slack to allow that... shouldn't there?

SPendrey Posted June 6, 2012 Author Share Posted June 6, 2012 I guess that's the lower small pulley? I thought I'd try that, but couldn't get it to move off the centre pin/bolt. Anyway, as the head gasket is now gone (I think), I have Mr Les Henson visiting this week, I'm sure between us we'll manage to get it back on somehow! Fingers crossed.

CwazyWabbit Posted June 6, 2012 Share Posted June 6, 2012 Yep, that's the one. I'm sure between yourself and Les you'll work it out I was looking at the parts diagram the other week and I'm fairly certain that it's just bolted into one of the normal timing case cover holes.... Btw do you think your head gasket went due to the aircon belt breaking the serpentine belt thus leaving no water pump? Quote Link to comment Share on other sites More sharing options...
SPendrey Posted June 6, 2012 Author Share Posted June 6, 2012 No, I don't think so. I suspect this is something that's been just creeping up on me! When the aircon belt went I was about 200 yds from a safe place to pull over, and the engine had been running for all of 2-3 mins, so not hot. I placed a spare on there which kept the water pumping round for the 2 miles home. It had then been running fine since, so as I said I think this is just age and load at the time (caravan in Exmoor).

CwazyWabbit Posted June 6, 2012 Share Posted June 6, 2012 Well I hope all goes well with the repairs Quote Link to comment Share on other sites More sharing options...
SPendrey Posted June 11, 2012 Author Share Posted June 11, 2012 I am pleased to report I wasn't going mad... Les agreed with me, the belts are too short. However, we can't find a valid reason why?! So now I need to find someone selling 4PK1330 or thereabouts, I did buy a 1368, but that's way too long. Quote Link to comment Share on other sites More sharing options...
CwazyWabbit Posted June 11, 2012 Share Posted June 11, 2012 Here's one, bit pricey though http://simplybearings.co.uk/shop/p650126/526K/1335PK+Major+Brand+Poly+V+Multiple+Ribbed+Belt+Allow+2-3+Days/product_info.html Quote Link to comment Share on other sites More sharing options...
Niamh Posted June 12, 2012 Share Posted June 12, 2012 Someone hasn't put spacers ubder the aircon pump have they? Quote Link to comment Share on other sites More sharing options...
