300tdi 100 Amp Alternators

OK everyone... I have my 300Tdi apart to replace the timing belt, get the cooling configuration back to stock instead of the mess the previous owner had in there, and other various stuff... and noticed that my alternator is looking pretty worse for wear. I think most of this was due to the many times I spewed oil and coolant out of the engine trying to get to Alaska last year.

So the short story is I am trying to find the 100 Amp alternator that will fit on a 300Tdi. There are many threads speaking of an Iskra that fits, as well as other strange combinations. But it doesn't seem like any thread has the info you would need to order one.

In the end... does anyone have a *part number* for something that fits? Doesn't need to be LR, just something functional.

I've been pondering the same thing for a spare. I see that there are 3 part numbers out there:
AMR5245 97-98 disco
AMR4248 94-96 disco
YLE101113 ????
But I don't know what the real differences are. Is it just pulleys? I hears the Yle one replaces them all. And something to do with heat shields....but I don't know. So sorry not much help, but I would like to know the answer to the question too. That's all the info I have so far.

Well mine doesn't even have a heat shield, so I guess that's all bonus at this point.

The Iskra fits, it's a 100 amps unit, cost around $180 brand new from supplier in FL. If I remember well the ref is in the old thread, but in case it's not I can retrieve seller, price and ref. I did had to swap pulley from old Magnetti, you'll need an impact wrench.

Yea me too on no heat shield with the current alternator. As I read it was a 3 bolt or 4 bolt mount on the heat shield but I really don't know what that refers to. So to the point I really don't get what the difference really means.

I think I understand that the smaller 4x mm pulley uses a 1580 mm long belt compared to the stock 1600 length. But I can't confirm that with part numbers and dayco cross reference. I have read that the belt should be smaller with the small disco pulley but looking up oem part codes and their actual lengths just yields the stock lengths, so again it doesn't seem to be conclusive. I imagine it will work with any stock belt.

Argh. Again I don't know. It seems like you can make anything stock disco work....

Am replacing the alternator on a 300 TDI in the shop and received the replacement today from Dingocroft in UK. It's manufactured by Denso IT - Part DAN 008 12V 100A 06M MSY63341-3210. There is no heat shield, but if the old shield and hardware from the factory unit won't fit am going to have a machine shop make the mounting studs and shield for this new unit. I think without a shield the heat from the exhaust will slowly fry the wires. It also worries me about not shielding the back where the diodes are typically located which are know for being heat sensitive.

Hope this helps.

There are lots of high output alternators. I can't imagine that there aren't several that fit. You should easily be able to find one that fits the mounting foot, puts out 200 amps at 1750 rpm and costs about $300.

I'm looking to upgrade to a 100 Amp alternator as well. Any recommendations for where to source a new Magneti Marelli that fits the 300tdi?

for posterity, I looked into this as well for my 2.8. The 2.8 comes with a Bosch 60A alternator and the vacuum pump is attached to the back of it, which is a constraint for substitution. Pendy told me if I wanted to go this route, look into seeing if the 2.8 block has the fittings to allow a 300tdi mechanical pump to it, to free it from the alternator. I have yet to pursue this, but if anyone else knows, I'd love to hear about it.

We have a 100 amp disco unit with prototype heat shield.

PM for pricing as I won't have it until tomorrow.

For 200TDI the alternator conversion is an easy must to upgrade to 169, 200, or 220 amp output.

What's recommended if you plan to run a dual battery set up? Is 100 AMP sufficient or is 120 AMP more appropriate?

I think I want to go with a Premier Power Welder when I get the three hundy in. They are spec'ing 190 amp alternators. Is there any alternator for this motor that could provide that current?

Doug, do you have a part number? Will the AMR2938 (120 AMP) work for a 300tdi? Is there a part# that won't work with the 300tdi? Can a petrol alternator be used for diesel and vice versa?
