Mk 1 Tdi Alternator Type?

[Alanuk]

Hi All,

 

I bought a replacement alternator some months ago on ebay when I noticed the charge warning light flickering, I have not seen this warning lamp for some time now but I have started to hear the "flat battery warning sound" in the morning now that the colder weather has taken hold. I have done the usual voltmeter tests and all appears well (14.3v with engine running) but the battery is due for a change as its about 4 yrs old and I plan to replace the alternator at the same time.

 

I have been looking at the Wood Auto web site to see if the unit I have bought is the correct one, the part number of the replacement Bosch unit I have is: 0 123 505 011, it seems to be in good condition and I was going to buy a new regulator/brush set for it before fitting it, I have the usual ghia extras fitted including the heated front screen so I assumed that this was the correct replacement being the 120A version.

 

If anyone could please advise me if I have the correct Bosch alternator for this car it would be very much appreciated.

 

P.S build date was 12/06/98.

 

Thanks in advance.

 

Alan.

Thanks for the reply zorgman, I dont understand what you mean by "checking the free clutch" can you tell me what this is please?

 

I believe this model should be fitted with a 120a alternator but there are a few different types with very different price tags, does any one know what type of 120a alternator it should have and if possible a part number?

 

Thanks again.

Hi Alan

 

I think "zorgman is referring to some of the alternators have a sort of clutch on them! I cannot see the need for one.

 

But I think most of the replacement alternators are Lucas ones, but have a look at this link, and to be sure put your reg in

the tdi's have a clutch on them. to check put small screwdriver to hold te fan then see if one way you can turn the pulley other way you cant, thats the clutch.

something to do with a mod that was done years ago for the bottom pulley on crank, ill find out for you.

check this out its with all tdi's from 90hp up including yours

Nice link, very much appreciated, thanks Radiotwo,

 

I think we are certainly getting closer....but I was trying to find a bosch part number for the alternator which was originally fitted to this vehicle, all the same I am really thankful the help you guys are giving me, its just that I cant find the correct part number for the Bosch alternator which would have been originally fitted.

 

Is there anyone out there with a copy of TIS or similar which states this info?..... It would seem that there are a number of differing posts relating to starting/alternator/battery problems to say that we could be on to something here...is it possible (because of the price differences between alternators (and they are quite vast) could point to the wrong type of alternator/batteries fitted to a lot of older Mk1 Shalaxies as/when they have had similar failures?...as soon as the winter approaches I start to experience low battery/starting issues, it definitely coincides to when I start to use the on board electrical extras such as the front heated screen....I know what some may reply "Stop using the heated front screen" but please don't be silly as that's not really the answer is it!!

 

I have searched long and hard but I cant find anything which states the correct part number of the Bosch alternator for this type of vehicle.

 

Thanks again, please I welcome any relevant comments.

Hi again

 

I am not 100% sure what you are wanting to do !

 

I get the impression you have a alternator and you just need to know if it the right one ?

 

Other than this clutch thing as long as it is the correct hand and all the bolts line up (and the same size pulley) which could make a difference then don't worry

 

as been said you need a 120 Amp output and as long as the battery is good then there is no problem what alternator you fit.

 

the only thing to test when on the car, is that it is putting out 14.5 volts and no more.

 

Just going back to the Bosch number, do a search on google, and you might be able to compare numbers.

You are quite right, why is it that some Bosch alternators listed for this car cost round
