what alternator is this?

[Stevewedd]

1974 Lightweight. Re-egined to a Rover 3.5L V8. I don't know if the alternator was then swapped out or not. I have this. No makers mark or serial number.

The local motor factor has exactly this model in stock but left-handed bracket, with no ability to identify the code for the wrong one so that he can order the right one.

What do I have? Maker, part number if anyone knows, please.

Looks like a fairly typical Lucas 17ACR alternator.
It is easy to change it from Right hand to left hand, it is a simple matter of unfastening the 3 long bolts and turning the front cover. They are available in pretty much anything from 45 amp to 80amp just depends on how much you feel you need.

Thanks, Neil,

More questions than answers.

The body on mine (and on the wrong one from the factor) is cast steel and can't be turned as you suggest.

All for sale on Ebay are ACR17 or ACR18 ('make sure you buy the right one etc'). Is ACR17 left handed and ACR18 right handed by any chance?

My factors supplier says that to supply what I have is a special build-to-order, non-refundable £160 order, compared to off the shelf on eBay for around £55, deliver tomorrow.

I hope that you can see the ebay offer compared to what I have.

I posted this for someone the other day;

To me it looks more like an A127?

As Neil says, you can usually swap them from RH to LH if they are the 3 bolt type, but beware that some have 4 bolts so you need to make sure you buy the correct one if ordering from Eblag etc. That one you have pictured is possibly ACR and opposite handed so its worth asking if they can supply the correct one.

You can buy ACR15, ACR16, ACR17 and ACR18. I believe they share the same body but are different outputs...?

My mistake, I had a V8 with an 80amp A127 alternator, sourced from ebay.
The scruffy item in the pictures is yours and despite your concerns it is possible to turn the front cover on it. However yours is inoperative so you want to replace it. On the V8 the alternator was mounted in various different locations, on either side of the V
If you need a right hand unit, this is s possibility.

Agreed its a A127. Extremely common and the cheap ones off e-bay seem to work OK. Pay around £70-90 for a UK supplied one You can also get a regulator and brushes for about £30 if the bearings are good, yours looks a bit old so I'd just get a new one. That Craddocks one looks as good as any.

I suppose there aren't any suppliers over there for the ubiquitous Delco 1-wire alternator? I actually buy mine locally from a diesel and auto electric specialist. My last 65-amp cost under $80 with tax, but that was several years ago and pre-Covid. I've been using them on everything, from a 1968 SIIA to an assortment of Volvo 245's. Can't beat 'em with a stick for price and ruggedness. Land Rover adapter consists of a high-strength bolt, and a cylindrical spacer faced off to the correct length to align the pulleys. In fact, when the Lucas on my SIIA packed up late one night, I once did an emergency midnight replacement using a spacer hacksawed from square stock and drilled by hand up the center (it's only about an inch, so no challenge) with the old Black & Decker. I've used nothing but for decades. Can't fit them to a modern computerised plasti-car, though. The computer has a Midol Moment if it doesn't sense the correct dainty replacement in the circuit.
