Hello fellow V8 friends.

So, id like to try to twin alternator my 3.5, to increase my output on tickover more than anything i think.

I have a 3.5 Disco with mulitbelt from cover.

I know glyn lewis does a bracket for the serpentine engine, and i could look at fitting a serpentine front end to my engine when i eventually strip it down for a new cam (at some point in the future)

however, if i could sort something in the meantime it would be nice.

I notice the water pump has a V spare which must be for the aircon pump fitted to some models. what i cannot guess is where or how the aircon pump would mount, what the belt arrangement is etc etc.

i was just hoping someoe might be able to cast some insight or betterstill provide some pictures of the belt setup on an aircon V belt model.

thanks in advance!

Hi mate

I did actually spot that online myself, but thanks for taking the time to find it and post it!

Yes I can see that there's some kind of compressor mount which appears to have a built in tensioner aswell.

I was hoping someone would have an engine in front of them so they could take some close ups!

Cheers

BTW the belt tensioner is not built in, it is a separate part.

Just had a quick look in Haynes, early Range Rovers had the alternator mounted where the air con compressor is on the later models. I think there is a mounting bracket rather than the cast aluminium arm that supports the compressor. So I would suspect you need to search for an early 3.5 alternator and mount but be aware the early alternators were not particularly pokey, the biggest was a Lucas 20/25ACR, 66 AMP.

KEV!

Thats superb, thanks a lot for those pics, and the info!

Yes, i was aware that the early alternator was on the drivers side, to be honest i wasnt sure if this early engine had a different front end though, ie, would it fit a 3.5 EFi model...?

Anyway, your motor looks exactly the same as mine, just with added bracketry, so if i can find something similar, like you say, i could be onto a winner.

The AC tensioner looks the same as the water pump tensioner from the pic you provided, makes sense. Also the AC pump mount look like i could pick up an alternator mounting there, looks similar. I am currently using Lucas 70amp which is original spec for my Disco, i get these from Euro Car Parts for about £38, another one of those would do the job nicely.

Anyway best get searching for range rover parts then i suppose.

Thankyou sir

No worries Mate. Mind you, have you seen the price of a belt tensioner?

I have indeed! I was looking a while back cos the bearing has gone in mine basically. I pulled out the cap, rinsed and regreased and machined a cap to fit in the end. I now run the belt really loose so an not to overwork it.

Could be a problem when it comes to fitting an alternator!!

Anyway, work in progress

Well, it should keep you out of trouble for 5 minutes!! Once I get mine fixed we should hook up, you're not that far away really. You ever get across to N.Wales for a spot of laning?

I'd be interested to see how you get on with this. I've been looking into it myself recently, I'll keep you updated if I make any progress!!!

There's a comp and bracket that I've spotted, just need the time and effort to collect it!

Any progress on this?? I've picked up an sd1 alternator, sd1 bracket, and an air con pump bracket as well. One day I might find time to see if any of it fits!!

No but thanks for updating the thread.

I have a couple of aircon pumps and brackets watching on eBay at the moment, mainly to remind me that I eventually need to buy one. Not had the cash available recently to delve I to a new project like twin alternator so haven't even made an attempt to start.

It will happen when I have time and money to throw at it!
