Took a few photos to illustrate what im explaining: Thats the breakage point, hard to see in this photo as its just a little crack but when you bent the belt it opens right up. You can see a stripe a few mm wide all along the right side of the belt which is a lighter colour, looks like it was rubbing at some point. Not sure if that and the crack are related but quite possible. Here you can see what I mean when i say the belt is pretty far over on the engine side. It's always been like that since I have the van. Last summer I tried moving it over to the left a few mm bit by bit with a screwdriver but it found its way back to that side in no time. Still, no contact as far as i can see. The part of the back cover which I said was all bent out of place is just under the clip in this photo. As you can see, its still far from straight but we bent it back so it stays far away from the belt. This is where I think it was rubbing. Photo is from the new setup. On the old setup there was contact between the wire and belt. The wire on the new tensioner still has a few mm of give if i get my finger in there are wiggle it, but it never reaches as far as the belt. Should be ok for now.
Na there are no arrows on it, I remember checking it when he told me that. For me it wasn't a proper explanation that the belt was on the wrong way round... so still no idea how the old belt died. Bit confused about which pulleys you mean, I didnt think there are any on the inj. pump belt? Both times i changed it (well, the first time was me watching someone do it) we just loosened the bolt on the crank coming from the camshaft, once the crank's loose the belt comes off. |

I mean the rear crank pulley and the fuel pump pulley. You won't find arrows as it's not directional - the belt I mean. I'd change the pump back to spec and keep an eye on things. Well spotted with that nick. Was only a matter of time before that belt would snap.

Just to push my point about the ACL having an 18 tooth pump, here's a link to a part that lists the pump for engine code ACL - btw this is the same group I bought the 20 tooth pump from and at that time they didn't list an 18 tooth pump. When I complained it was wrong their tech people didn't have a clue about this error.

Just to clarify in hindsight... Messing with the size of belts was unnecessary and a mistake. I was having difficulty getting the recommended belt to fit so got one a little bit longer. The problem lied in the way the alt was positioned. Somehow it wasn't perfectly positioned and the alt being taken on and off revealed that later. Point is, if the OEM part doesn't fit then you need to check why. The longer belt was a short-term solution however underlying issue should have been resolved at the time.

Old thread revival BUT I think I've spotted a problem here that might be the root cause. Junk, the bottom of your last photo shows the water pump sprocket. I'm pretty sure you've got the wrong water pump fitted! Looks like you've got the earlier water pump. If your engine is an ACL then it should be the same as the one in my photos. Notice the different sprocket? The old water pump position is adjustable to alter cam belt tension. The ACL's is not. It's position is fixed and the cam belts tension is determined with the tensioner pulley.

hey monster LT.
Its a couple of years ago now and I don't remember at what point in my long cambelt story I took that photo. In the end it went like this: -first paid a mechanic to change belts and pump -fuel pump belt broke unexpectedly and the front end (around the cambelt) was making a horrible noise like a broken bearing when the engine was warm -i decided that the mechanic I'd gone to had obviously scammed me but I was already out of the country, so I changed the cambelt and tensioners with a friend. The horrible noise went away so I assume it was the bearing from the tensioner. -six months later I noticed the cut in the cambelt which I posted a photo of. When I turned the engine it made a horrible squeaking noise which a friend reconed was a broken water pump. (I think this is when I took that photo) -we changed the cambelt and tensioners again, and this time the waterpump too. When we took it out it had the original 95 stamp on it, so the mechanic I had paid in the beginning of the story had obviously either not changed it or changed it for something from a scrappy. -we ordered a new water pump and got sent one with the adjustable positioner bolt and a different number of teeth (which we've been debating earlier in this post) and we fitted it -after reading your posts and losing some sleep I ordered another new water pump, to match the original, with correct number of teeth, and fitted it. And since then I had no problems. So in the end my cambelt came off and went back on again about four times in a year but at least we finally got it sorted.

anyway thanks a lot monster LT for your posts coz it's that which helped me figure out what was going on with the pump I had ordered.
Moral of the story is that a lot of parts suppliers incorrectly list 20 tooth water pumps as a part for the ACL engine but don't believe what they say, find an 18-toother!
