Generator/alternator for my d6 9U

More
17 years 1 month ago #6797 by ttman4
My tractor has a homemade looking plate over the spot where a generator would normally go.
I been thinking about adding a generator there at some future time. Poking round I saw where some of you guys had rigged up an alternator & bracket above the generator, using a rear mounted drive pully to drive the alternator.
Looked like a neat idea.
Anyway, me without an existing generator, what/where be a good place to start looking for something to mount there. And what kind of $$$ for a generator.
If an alternator is rigged up, then I guess a non functioning generator could be used?
Or any other thoughts to rig up a charging set-up?
Right now I can charge up my battery for my starting engine & it lasts quite a long time, surprisingly. But I got some other modifications I'm playing round with that I'd like to have some charging ability for.
thanks

Which way you go for some kind of "charger" will depend on what voltage and amperage you need. If all you need is keeping the 6 volt bat for the starting motor charged and a few lights, then the stock generator might be the cheapest. The next most common thing probably is a stock 24 volt generator from the direct electric start option package. I have heard of folks finding or having 6 volt generators converted to 12volt by an automotive electrical shop.

If you need 12 volt for some reason and still have the pony starter, they function quite well on 12 volts instead of 6.

there are kits for gear drive alternators in the same hole as the standard generator and as you saw modified generator frames with a long shaft inside can be used to drive most anything, but usually a Delco 10SI is chosen.

I would stay away from the 1 wire hookups since they seldom excite on a slow turning engine unless you race it up to make the alternator go. It's not too much trouble to wire up the regulator plug to a switched source of battery voltage for the #1 or R terminal. the #2 terminal (on the right as you look at the back of the alternator) can be connected to the output stud with a short jumper.

If you don't want an ignition switch, you can use an oil pressure operated switch to turn the alternator on when oil pressure builds up an off again when the engine stops.

D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time:D

Here is what a lot of us did up here, Ttman: Gutted the old generator, put
bigger brgs in the output end and usually shortened up the old gen. case.
On my 9u, we then hung a double pulley on it so we could an alternator &
a AC pump. No changes for the starter on the pony....just lay off of the
button. The 12v system made it real easy to plumb in all the comforts of
home....heat, air, lights, radio.....:)

Thanks CC.
I now use a 12volt battery for my pony that I hook to a charger every so often, & that does OK most of the time.
But I'm trying (thinking it out & scheming) to rig up a charge system for some other 12volt needs....ie:
(soon as I got my set up finished I was gonna update my thread from about a month ago when I was having thermostat & too cool coolant problems)

I been setting up my veggie oil fuel system & bout got it all going & bugs worked out. This thing does run good on veggie, but the trick is heat.
After I got my heat regulators (thermostats) fixed I got heat, but I need to rig up some additional oil-fuel heaters....glowplug-in-oil heater, or something.
But that's a different story.

Anyway, I need to find an old gear driven generator that I can rig up & then mount alternator or something onto.
Unless someone has other idea of how I can come off the gear drive with something else to turn things.
Thanks. Gotta run.

Ahhh 98j, just now posted mine & there you was:D
Your pics, this is what I was thinking about. But I don't have the original generator to gut. I need to find one somewhere. Anybody?

(if I got AC on mine, then I'd want a spa, wetbar, hot tub, chaffour driver.....:D :D )

You mite try General Gear and Machine in Boise Idaho for and old generator.
There web site is www.tractorparts.com If they do not have one they may tell you where to find one. We have a similar setup like 98J and it works very well. You should be able to locate one without to much difficulty I would think.

Hi ttman4,
The D4 & D6 share the same generators and housings but be aware there are two versions. The4F6980 is a two gear (higher speed) unit and the 4F6978 is a single gear drive.

The Cadillac version is the direct coupled alternator with lovjoy flex coupling drive. They have the motorola flange mount pattern which is also available to mount the Delco 10si. These are a bit pricey unless you can find one used.
