Pug 306 tdi generator seizure problem

[crankedup]

Had new timing and generator belts fitted about 900 miles ago and the generator seemed to seize up. Impossible to spin the pulley wheel at all by hand once we got it off the car. Fitted a good used one and within 50 miles the same thing has happened.

Could overtightning of the belt have caused this?

Thanks for comment/advise.

I suppose it's possible, although unlikely. Doesnt it have an automatic tensioner ?

[crankedup]

Thanks for reply. Its my lads car so not sure if it has the auto tensioner, I will check. Just seems to weird that two alternators should give up within a couple of weeks of each with same problem.

[stevieturbo]

Perhaps. But if the replacement alternator was used...you have no idea of it's history.

It should not have a self tensioner fitted so long as its an XUD 1.9TD and not the 2.0HDI model, these cars are not prone to this fault so can only assume it's the Serpentine belt being over tensioned fit another known good unit and tension the belt to get a 90 degree approx twist on the longest run and you will be fine

You access the tensioner from the wheel arch. There is no feel for how much tension you are applying as you just wind away on the nut so it would be quite easy to overdo it.

Quite right and often referred to as the pendulum in XUD circles 2 6MM Allen headed bolts as I remember

Job was done by local garage, new timing belt and generator belt fitted. To late to complain as car has covered around 1k miles since fitting. Quite annoying when you pay good money for work to be done.

Don't be daft I run a garage and if I fitted an alternator that only lasted 1k I would be expected to replace it and I would no argument as many other garages would too you should have taken the car back before you touched it really

Hey, I run a garage as well, and as a minimum I would offer to fit the new alternator for free. It's no big deal,and for me the goodwill is worth more than the time.
