hello brickies!

I read the forum a lot but dont post much, but after what happened today i thought it would be worth sharing my experience.

Was driving on the french motorway and the engine cut out while driving and wouldnt start again. Managed to get the van off the road with the help of some friends and we opened up the engine cover to find the timing belt broken and hanging free like the undone belt around my jeans at the end of a long day.

Thats the timing belt at the back by the way, the one for the fuel pump. The f'ed up part is that i got it changed in a garage 2000km ago, the belt is so new its still got the text on it.

Has anyone had this experience before, a new belt breaking on them? We were wondering if something might have gotten caught in the fuel pump, creating tension which broke the belt.

Advice on what might have happened and how to check it appriciated, as are similar experiences you may have had.

Its an LT35 TD from 1995 (LT 1)

on closer inspection today we saw that 7 of the teeth were ripped off the belt next to where it snapped, looks like there was a moment of great tension.

spoken to a few people, heard a few different opinions about what might have caused this:

-the mechanic who replaced the belt didnt do the pressure properly
-the diesel pump got stuck somehow, causing the belt to be pulled very hard
-the belt itself was of shitty quality. Its a brand ive never heard of 'SKF'. one observer pointed out that these belts should have metal thread running through them (inside the rubber) to give strength, whereas this one is just rubber.

skf are decent stuff, if it’s stripped the teeth something has most likely locked up, I would check to see if the pump rotates, if it’s just the fuel pump belt fit another and turn it over a few times by hand before starting it, it could quite easily be a faulty belt but it’s not very common

Presumably the fuel pump is driven by the camshaft etc, you need to check this out too.
Pumps are self lubricating via diesel, if there is a leak it could have run dry.

The main cambelt in front of the engine run the camshaft, and the camshaft in the other end run the dieselpump. So it is 1 of 3, 1 the diesel pump has got stuck, or is harder tu turn, 2 there has been mad a mistake when the cambelt was instaled, to hard or to loose or 3 there has been som fault With the cambelt.

SKF was the mother Company when Volvo was founded and is/was the leading roller bearing produser of the world. SKF means Svenska Kulelager Fabriken= Swedish Rollerbearing faktory. Volvo is latin for "I am rolling"
