Alternator Upgrade 2H

[sandcruiser]

Is there a way to improve alternator output for the one in my HJ60?

It works fine now, but I've just ordered upgraded lights (100/55 w/ Cibie) and will be installing upgraded reverse lights, and also driving lights (its dark here) as well as a 12v booster heater for my SVO setup, and the winch (which doesn't get a lot of use).... then there's the stereo (which does get a lot of use) and eventually I'll probably hook up the CB again....

Anyhow, I'm starting to doubt the sufficiency of my 2H's alternator. But that dang vacuum pump on the back makes it tough to simply swap in another alt.

Has anyone hooked up an Aux. alternator in a 2H? Or rewound the stock one for more power? Is there some other option that I'm missing?

I've already put LEDs in the dash, so that'll save me an amp. ;p

I'm planning LED's for the stock reverse lights and maybe the tail lights, so there are another 2 amps or so.

Anyway, just trying to plan ahead.... and still sorta trying to justify the notion of a hydroboost brake system (since my booster is going south anyway) cus that would open up some options for different alternators (and/or reduce the load on the stock alternator).

And on that point-- there is one single vacuum line besides the booster.... can one install a small (cheap?) electric vacuum pump to run that?

some vehicles, fords I think have a belt driven vacc pump, or I think I heard noises once about an electric vaccuum pump...

I know what you mean about the upgrade, presently my ol bj40 still has a stock alt on it, but I replaced it once ( and was very lucky that I found a cheap replacement, largely thanks to a kind cruiser horder...)
but when this one goes, I'll be looking into plain 24v alts and dealing with vacc issues some other way.

cheers,

Cummins use a electric vacuum pump.

Then find a heavy duty alternator. Easy for the 12v guys.

Not certain but isn't the unit from the HJ75 rated higher than the wagon unit? Mine runs the headlights, 4 spotlights and a big bull lamp also the sterio and amp.LOL.

Some Saabs, Volvos and VWs have 12V vacuum pumps for cruise control, etc but they are not of sufficient capacity to run a brake booster. Speedshops sell 12V vacuum pumps for brake booster use in cars with wild cam profiles, these might fit the need better, but they are quite spendy.

I recall buying a Euro-spec 40A alternator for my old 2H but the one it was to replace was a 55A Aussie-spec unit. If what you have, Steve, is the 40A unit, maybe you can get the 55A unit?

not sure of the output currently, but I'm thinking it would be good to start thinking about upgrades before they are actually *necessary*. An then there is the hydroboost... now that my booster is iffy.... I'm feeling the pull of the old "why not make a VERY complex solution instead of a simple solution?"

HA . ! my way.

Ok .. the factory 2H alternator gave for us 60 amp ( I thought after many and many years working with luck 50 amps ). So planning upgrades with your stock alternator maybe include a new small pulley and new wiring burshes and stator.

A good electrical shop can do this job .. in my case for about 150 USD I have actually a 90 amps alternator.

Off course small pulley more wear out. But who cares.

Other option for sure a electric vaccum pump .. in summit you con buy one up to 250 USD .. Auuuchhh ! and put any alternator that you want.

So here some friends with the same dilema, buy an Hyundai Galloper Alternator, with 115 amps and vaccump pump included, so you only need to make a new bracket.

Excellent. I think I can get a Hyundai alt pretty cheap-- the darn trucks wear out fast around here.... I'll look around. After I get the brakes fixed

To throw another option into the mix, and probably create a bundle of controversy::::
When the alternator on my 24V HJ61 12HT was not up to scratch, the auto electrician I took it too replaced the brushes, and then found that if he put a stator from a 12v alternator off a 2H, rated at 60A, then my alternator then produced 24V at 60A. Bit of a trick he knew about apparently.

Now; people with far greater knowledge than I, (who doesn't even know which part of the alternator is the stator - the thing that spins in the middle or the casing around the outside that does something clever) - say this is unlikely to be possible. But heck, it worked on mine.

Might be a line of enquiry, or the start of a massive debate! I'm just telling ya what happened to me fellas.
