Defcon5 Posted December 31, 2012 Report Share Posted December 31, 2012 I doubt you need a new pump Quote Link to comment Share on other sites More sharing options...
Pete Posted December 31, 2012 Report Share Posted December 31, 2012 Can I assume the belt snapped while the engine was running? Quote Link to comment Share on other sites More sharing options...

Pete Posted December 31, 2012 Report Share Posted December 31, 2012 I've known a belt to snap before whilst being removed for another reason, so just thought I'd best ask the question, but yeah, kinda like asking for a bandage for a cut on your leg and ignoring the fact your arm is hanging off.

Pete Posted December 31, 2012 Report Share Posted December 31, 2012 Cheers dude! I find when working with spanner bitches.....I mean apprentices, good visual examples seem to stick in their minds a lot better than blinding them with science, so I've got a million of em.

Derv Posted January 1, 2013 Report Share Posted January 1, 2013 I had a belt throw off due to a seized alternator freewheel pulley. No big deal as I have a big battery and no PAS, so got the car home ok. When the belt came off it broke the tensioner, so I had to replace that along with the alternator. I just used it as an excuse to renew the aging alternator really. Just a new pulley may have been fine. 1 Quote Link to comment Share on other sites More sharing options...
squishy Posted January 1, 2013 Author Report Share Posted January 1, 2013 (edited) Hey thanks for all the help and reply's.... Im still kinda stuck though, Im thinking its just the seized pulleys as they are tight especially the PAS pulley, also the ALT pulley gets about 2 spins outta a flick! the tensioner still looks like the original from 100k ago so im thinking thats a big cause to the belt sanpping, I would say the belt was only a few thousound miles ago but obviously installed by a monkey mech you never did the tensioner!Yes the belt snapped whilst engine running, I pulled away from stand still into a round about and boom heard something and then pas stearing failed, ther engine bay is unclean and some crap might of helped it twang along with the seized pulleys etcso what further damage could there be??oh yeah also my pump has not leaked or lost any fluid since this happened... Thanks again Edited January 1, 2013 by squishy Quote Link to comment Share on other sites More sharing options...
Pete Posted January 1, 2013 Report Share Posted January 1, 2013 Ah, I get you now, not the drive belt, the aux belt!! Quote Link to comment Share on other sites More sharing options...
squishy Posted January 1, 2013 Author Report Share Posted January 1, 2013 Ah, I get you now, not the drive belt, the aux belt!!Er yeah.... the aux belt, so this pas pump number where is it located behind the pulley the only number i can find is the one in top post but think thats wrong to Quote Link to comment Share on other sites More sharing options...
Pete Posted January 1, 2013 Report Share Posted January 1, 2013 You should be able to pick up a second hand one fairly easily, but I would think in order to get the part no. for the pump you'd need the pump off the car, a vid would be nice of how bad the pump is tho, as really in an ideal situation the pulleys shouldn't free wheel for too long at all when spun by hand.

scotty_82 Posted January 1, 2013 Report Share Posted January 1, 2013 Big difference right there Quote Link to comment Share on other sites More sharing options...
Pete Posted January 1, 2013 Report Share Posted January 1, 2013 Plus I wouldn't worry too much about part no.s as they tend to get superceeded fairly regularly anyway, personally as the belt is off anyways, I'd whip off the pump and have a general look at the layout of it, I've just looked at 'lupo sdi pump' on eBay and 3 have come up, different numbers on there but look similar if not the same, couldn't hurt to try one if your pump is indeed seized and if it turns out to be different then send it back no problem.

Pete Posted January 1, 2013 Report Share Posted January 1, 2013 I'd think lupoboz could help on that one, being a parts guru his system may have the belt layout on it, I know the merc and BMW/mini parts systems do. Quote Link to comment Share on other sites More sharing options...
Derv Posted January 1, 2013 Report Share Posted January 1, 2013 I would just change the pulleys and tensioner, get it running and go from there. PAS pumps normally sound horrible before they fail. Quote Link to comment Share on other sites More sharing options...

billyyoung Posted January 2, 2013 Report Share Posted January 2, 2013 (edited) My wifes car has done the same the teeth strippped on the belt , but she was on the carriageway at 70 when it happened . I'v had the rocker cover off and there has been contact between the pistons and valves the hydraulic followers on 3 and 4 have been damaged by the valve stems . I'v not had the head off it yet but I would imagine the pistons to be quite damaged aslo with the speed it happened at.

James827 Posted January 4, 2013 Report Share Posted January 4, 2013 I wouldn't drive an SDI without an aux belt, the water pumps driven off it! Quote Link to comment Share on other sites More sharing options...
Derv Posted January 4, 2013 Report Share Posted January 4, 2013 The water pump is driven by the aux belt? And the cam drives rockers? I didn't realise the SDI engine was so old skool. Every day is a school day. I need to get my head back into some SSPs! Quote Link to comment Share on other sites More sharing options...
