Drive Belt Problems

[Steveenduro]

Hi. Last week I the drive (auxilliary) belt snapped on my 2000 Mk 2 1.9 Tdi.

The pulleys looked ok on quick inspection so I figured the belt failed due to age. Oddly, it was split down the middle.

Today, the new belt also failed in the same way. I spent a bit more time on inspection and found that the steering pump pulley had an outward bulge at the rim. I thought that this must have caused the belt to ride off pulley. I couldn't get hold of the pulley from stock and so have ordered one. In the meantime, I did my best to straighten the old pulley and replaced it with a new belt. I started the car and inspected belt/pulleys. I noticed that the belt was only half on the tensioning roller. The tensioner seemed to have side-side movement on the arm so I replaced the whole unit with a Eurocar part.

I now think that the damage on the PAS pulley was a result of the belt being forced of the pulley when the tensioner was misaligned.

It all looks a lot better except that the belt is still not central on the tensioner roller. Nothing as bad as it was though. It sort of lines up with edge of roller on left side, and sits on roller with a couple of mm spare on the right.

Is this ok? I could put a washer or two under the mounting lugs to centre it.

Has anyone else noticed this? Have I now sorted the problem or is another belt due to bite the dust?

 

Many thanks

hi steve

 

i had a similar problem with my passat, the tensioner pulley spring arm had come of its plastic sleeve and over the lower bolt. The alternater pulley failed and caused the problem, but on reassembly i noticed everything was out of line and so also replaced the tensioner with an extra washer the keep it straight and to stop the arm coming of its sleeve again. Everything has been fine ever since. Good luck and maybe keep a spair belt on board just incase

Thanks. The tensioner on mine has done 210,000 miles so I guess it was due replacement! I'll put some washers on to centre it up - can only help.
