Alternator help

[dogruffracing]

My alternator pully let go damaging the shaft last monday, ive been into GSF and Euro who say there is none of my alternator type in the country! gsf said they could get a replacment that was not Bosch but it turned up and was wrong, my local factors have supplied 5 alternators so far and none have been right cars been off the road 8 days and ive been hiring a van thats costing a fortune, i really cant believe i am having these many issues on such a common car, the alternator is hard to get as it has a clutch pully on it and is 90 amp this is because my cars the peasant model with no air con and this is supposed to be rare according to the GSF gimp

1998 audi a4 1.9tdi 90

Bosch alternator numbers
bosch 028 903 018 fx 03
KC . 1413 - 90A
042

When GSF cross ref the numbers they supply the wrong alternator if they do the same with the pully they get the right pully....... oddly


Any ideas?

Thanks

So 028 903 018 FX is what is on the car now? If it is, this is already a replacement unit as 028 903 018 FX is the VAG replacement number for the original 028 903 027 S (Bosch) or 028 903 027 T (Valeo). It is a Bosch 0 123 320 048 or a Valeo 436449, trade number NA440. They tend to be supplied without the pulley from Bosch which must be purchased separately but Valeo come with the pulley however this tends to be the incorrect solid type which causes belt flapping and tensioner failure.

Hi. I've had/got two 1.9Tdi's. One 1997 afn engine, no aircon. One 1998 AFN engine witn aircon. Both had fitted 028 903 028. I replaced the former when the pulley bearing failed. The replacement took some finding (two specialist Audi breakers didn't have one, but had thousands of others... and knew it was important to get the right one). Eventually found one on e-bay. As Crasher suggests the one you have may not be original - I would use the car details to get the number of the original alternator (from Audi? or Crasher?) and any subsequent suitable replacement numbers.

Just a thought, if you're not able to find a new one you could try a breakers yard. If you manage to fond the correct alternator you can have it rewound by an auto electrical specialist. It'll be as good as new when you get it back.
