I am trying to collate all of the info on the forum on Holden alternators into one thread. There is no shortage of info on the LC and LJ Toranas, (although not all of it can be correct) but I can't find much at all on the bigger cars.
First of all, I cannot find any proof that any Torana built after Jan 1974 has ever been fitted with a Lucas alternator, even though they are in the parts books and workshop manuals. This flies in the face of a few "elderly" gentlemen that I have contacted who seem to remember them on L34's and other early LH's. My L34 has a Bosch, but it is missing the 3 inch pulley so it may have been replaced. Eyepeeler's has a Bosch with the (very rare) original pulley.
So if anyone can provide proof of a Lucas being factory fitted then please post it up.
I am also chasing part numbers from original Bosch alternators. At this stage of my investigations, I believe that early 1974 should be around 9 120 060 805 (55amp) and October 1975 is 9 120 060 847 (40amp), which also runs into 1976.
It would be great to get confirmation and photos of alternators fitted to A9X, UC (inc 4 cyl) and all models in the LH-LX range.
