Looking for Suggestions and Perhaps some Photos please of Fitting a 24 Volt Alternator to a 7U D4. The Tractor has been Fitted with a 24 Volt Starter, but never Had any proper Charging Unit , still has the original Gear driven Generator Mounted which We assume is 6 Volt. Have seen Generators cut up and Made as Base for Alternator and And the Alternator mounted on top and driven by a couple of Vee Belts on a D7D 17A. Is there an Adaptor Base with Alternator available either in Aussie land or the US . Any help or suggestions Much appreciated . LJ

Hello LJ. I can take a photo of an alternator with adapter that takes the place of the generator. Pretty clean adaptation in my opinion. Coupled with a Lovejoy style coupler. I found one of an old 17A of mine. More photos tomorrow. JM

I believe this is the current preferred unit...
Try Florin Tractor, I think they have them. Not cheap though.

Hi Lance , Might be worth a phone call to Jim Davis auto electrical Toowoomba ..
He does electric start conversions for old cats , so may be in the know for alternator conversions as well .

Maybe it just me or I don't know the machine, but I think I could have a mount fabbed up and a alt from local parts store made and on in a few hours?

Belt alignment is the only critical thing here and it's not that critical with v belts,close enough is good enough.

One of the first things I did to the d3b we have is to put a GM 1 wire alt on it,fabbed a bracket to fit,no more dead batteries

Depends on what kind of installation you want. Lots of farmer built mountings but only a couple that are clean installations. I'd avoid the ones using Motorola or Leece Neville alternators. They seem to want a ransom for units and parts.

Lance-

Contact OzDozer. If I remember correctly he and a friend were working on an alternator adapter system to replace generators. Perhaps Mike Meyers might remember more.

This is what I did on D69U. One wire alternator, works great even at low idle.

I did this for a 9UD6 with a cable blade. It left the gear drive generator open to make an adaptor to drive a hydraulic gear pump for hydraulic controls to angle and tilt the blade. Speeds up the rpm of the one wire alternator to charge at a low idle. Does not affect the tightening of the belt which runs the water pump and fan for cooling.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
