AC to ACR conversion

Seems to line up to me. It's the Lucas version as opposed to the Ford version which has a screw terminal. I'll double check it's not ever so slightly wrong and I'm stressing the belt. I only fired it up briefly to test so far as we have snow.
 
Peter: I'm leaning in the direction of replacing the 11 AC with the 127. If I understand correctly, the only serious issue is increasing the size of the main alternator cable? I've looked online and there are several "127 alternators" on the market. Is there a specific one that you recommend for this application (1972, 3500 auto)? The alternator in this car is mounted on the right hand side of the engine/ the left side if you are facing the car from the front. Is this considered a "right hand" mounted alternator? You had posted directions and a schematic of your car's electrical system earlier. I have this info. Thanks, Drew

Replacement Alternators
 
Be a good swap then Drew. The handed problem on the old ACR is not much of a problem, as they can be changed very easily anyway. So if you did get the wrong one it's no big problem. Don't know about the newer type as we have not used one. Our P6 is a Mk2 so the alternator charge cable goes to the starter terminal. We just added a second cable to reduce the load on the single one fitted. We have been preparing race and rally cars for forty years, so have got used to finding solutions to problems fitting things where they were not meant to fit. See how you go.
 
I swapped my 11AC for an A127 and found it to be pretty straight forward. It bolted straight in and the pulleys lined up ok, the only thing was that there was not enough adjustment on the bracket to tension the standard belt. I was going to look for a shorter belt but found an old MGB bracket in the garage so I cut it in half and cut the end off the Rover bracket and welded them together. This gave me the extra adjustment and I could keep the standard belt.
Its the left hand one you need and it was cheaper than the voltage regulator for the 11AC.

Hope this helps

Dochie: Which A127 did you purchase? I've gone on line looking for "Lucas A 127 Alternators" and several show up. Of course, none have an application for a Rover. Thanks,Drew

The alternator I fitted was from apdtechnologies priced at £49.99.
Put A127 into ebay and it is the first one to come up

Exactly it's nuts to replace an 11AC or 4TR when this is better in every conceivable way unless it's a show car where originality is key.
 
Not having worn bearings the car sounds somewhat different.... Surprising how much noise it made.

My original post was to fit an ACR to a 4 pot NOT a V8. The pulleys will not line up on a 4 pot if anyone is thinking of a conversion.
