Looking at the LJ Parts Catalogue, it appears that the Bosch alternators for that period are the same on the 6 cylinders. 35 amp 13.5 volts. The "Generator Assembly" has a different part number to the others, but that would be because it includes the larger pulley. The only additional individual components mentioned specifically for the XU-1 are the pulley, 2 braces (instead of 1), and a bolt with extra length to accommodate the extra length.

Assume they'd be similar except maybe detail changes that xu1 had.
Jump up to 55 amp if you as they all bolt up the same

Hi Baz, i forgot to ask could you please tell me what the part number for the 9/72 xu1 alternator is mate ? Gary.
The part number for the "Generator Assembly (Bosch) XU-1 eng.) is 2820452. That is largely irrelevant, because the part number would only appear on the spare part packaging.
I can only assume that the original would have had the zinc plated fan and black pulley.

Hi Tony
The casing changed with the LJ - no longer had the black plastic grill thing on the back

Baz, would you possibly know the part number on the sticker, Like the 9 120 060 661 ect, by any chance mate ? Hope that's not being a pain, thanks Gary.
9 120 060 679 is the correct one. Mine has the same number but ends with 677. I was on it when I got it and it works fine.

From my memories from back in the day there were 2 different alternators fitted to Holdens.
One was Bosch the other was Lucas.
Without the knowledge of the rivet counters back then, I could find no reason for which was fitted to what.
But working at a mates Service Station from the mid 70s I changed many of them.
Always used Lucas Exchange alternators.
Was a big thing when the ones with the inbuilt regulator came on the market.
Also rebuilt a few myself.
Be very careful removing the bearings especially the rear one.
You dont want to move the slip rings at all.
If you do you will more than likely break the wiring to the rings and render the unit useless.
Check the diodes.
Best to remove one leg of the diode from the circuit before testing.
Should be 9 of them to test.
1 faulty one will cause dramas.
