Hi guys just inquiring for a frind if all
adelaide xu1's used only lucas
alternators or where some bosch in
particular 9-72 thanks, Gary.

Hi

My 10/72 Adelaide XU-1 has a Bosch alternator with Bosch external regulator. To be correct, the alternator should also have the 3 inch pulley. My reading of the parts catalogues conclude that all XU-1s used a Bosch/Bosch combination until the introduction of the Lucas alternator with internal regulator in 1973.

I would be happy to hear any other opinions. A lot of XU-1s were retrofitted with the later alternators which were more reliable.

Cheers

Bazza

Bazza, the earlier Bosch alternator with the external reg. was fair more reliable than the Lucas one. The later Bosch with the internal reg. was not very reliable (the early examples anyway), but I'm not sure any were fitted to LJs. I think they were more an HJ/LH thing.

Trust me, the Lucas alternator was a major pile of excrement.

I realise the turn of events, I was just disputing Bazza's claim that the Lucas was a superior unit to the Bosch, when everyone in the trade knows otherwise.

The Lucas internal reg alternators for LJ 6cyl and XU1 were introduced into production possibly around June/July 1972.
The new Lucas alternators may not have been used exclusively on the production line but alongside with Bosch alternators.

info that you do, can be a huge help

[73SUNBURSTEXYOUWON]

Hi all, coming in on this topic a little late reopening or confirming the can of worms. Just getting this right for me, my 4/73 Adelaide built XU, should it have an internally regulated Lucas alternator/ and what amp rating 45? SO the starter should be Lucas too?

Thanks

Jason

The correct information on xu1 alternators ....No xu1 received a bosch alternator after May 1972 which i have stated previously. cheers

I believe that the alternators where obtained quite a bit in advance, someone i know contacted bosch and was told that they where "apparently" fitted up to around the 10/72, i am talking on the Brisbane built car's, with that statement though, not Adelaide !

Mines a 5/72 and fitted with Bosch alternator which I believe to be OEM?

Can someone confirm the alternators for

Adelaide XU1 Lucas ?

Brisbane XU1 Bosch’s

And when did they change to internal regulators ?

During 1972 is when they changed from external reg to internal reg. Bosch did not make internal reg alternators at this time. Manufacture of Bosch external reg alternators ended in May 1972. AFAIK all LJ 6cyl Torana fitted with internal reg alternators were fitted with Lucas. My mate Pete's 8/72 Brisbane built LJ XU1 had a Bosch external reg alternator and I believe it was the factory fitted item.
