Hi to alls
Would anyone happen to know the American supplier(s) of this specific alternator for the Jaguar MK2 with power steering?
Sold by Limora : https://www.limora.com/en/alternator/503627/

My best regards

I don't have an answer to your question, but I wonder if it has been converted from one of the diesel engine alternators that have a vacuum pump on the back.

 

Thanks Peter
My problem is that Limora won't tell me the name of the supplier.
I installed this alternator, but it only worked for a very short time.
It seems the regulator might be the issue ?
I would like to know if the regulator can be removed and replaced.
Only the supplier could tell me that!
My best regards

Given the price, they should replace it without argument.

 

Are there not any markings on it to identify who might have made it? If not can you find someone locally who rebuilds alternators and take it to them?

They can probably fix it and tell you what it was originally at the same time.

 

It looks very similar to the one I used as a DIY solution. That came from a Vaxhaul Astra 1.7. I believe the alternator is a Hitachi. It looks like the one sold by XK's/Moss

You can probably take it to an alternator rebuilder and they can match up the regulator.

 

Hi Jagboi64

Would it be possible to send me a photo of your DIY solution with the Hitachi alternator for Opel
My best regards

Version 1: In this version I used the vane holder for the vacuum pump to fit on the shaft of the alternator. Into that, I cut a slot and used the original coupling between the generator and the PS pump. That didn't last too long unfortunately, as slack opened up and the coupling came out of the slot.

Version 2: I made an adapter that fitted into the end of the PS pump (post 13 in the thread linked above). I took the portion of the vane holder and turned it down in my lathe to a cylinder. This piece had the internal spline to fit on the shaft of the alternator, so I needed that spline fitting. I made a mating hole in the adapter that was slightly smaller than the diameter of the vane holder diameter

. I then heated the adapter and froze the vane holder t get enough clearance to assemble them, and quickly pressed them together. When they came back to room temperature, the outer portion was shrunk on the to centre and doesn't slip. I put the setscrew on as a "belt and braces" approach, but it wasn't necessary. Heat shrinking two shafts together is actually one of the strongest ways to join them. It's torque capacity is double compared to if you took the same two shafts with the same interference and cold pressed them together. So far it's holding up well.
