8N 6v Generator rebuild?

[Hammbone]

Does anyone know where I could find the necessary parts to rebuild a 2 brush 6v generator? All I have been able to find are the brushes and bearings. Are the field coils and armature still available anywhere, or am I wasting my time?

try a rebuilder.

since the genny are being repoped.. parts ARE available. expect it to be indian or turkey or china origin however.

I have not found a local rebuilder yet but I have not looked to hard yet. As far as the overseas parts, have you had any positive experience with this route? I guess I should have also asked if it would be worth it to try to rebuild or if I would be just as well off buying a repop? I had considered going the 12v conversion route, but the tractor has no problems firing up first crank on 6v so I don't see much advantage there.

I have parts from all 3, they work, not as nice looking as old tech ford.

Alright, I finally found the parts I need to rebuild the generator at a local auto electric repair shop. They tested the armature and turned down the commutator, and ordered bearings and brushes (Korea and Taiwan) and also a set of field coils (Canadian, little surprised there). I have everything torn apart and cleaned up except the rear plate and bearing. Does anyone know a good method to remove this bearing without tearing the end plate up? There isn't a way to get to it form behind that I can tell and the FO4 manual doesn't really go into detail on it (actually states that it has a bushing instead of bearing). Is there a special tool for this?

bozo that i am. would be using an "awl" and a hammer. and work my around the outside some. to point i could get some needle noose pliers on the old bearing to twist and pull it out.

screw driver will leave marks, but *shrugs*, my issue has been if i can get the "center" of the bearing out... ya got the outside, then the rubber (black) then the center metal ring. if i can work out the center metal ring / rubber. the outside of the bearing comes out easier.

==========
slide hammer... get a concrete / mansory anchor (butterfly types) that ya push together, and then push through hole. and then once pushed far enough through 2 legs spring out. find one that is small enough to go through center. and some how do a "slide hammer" job on it. *shrugs*

find a rod to fit in the bore, fill with grease. hammer ont he rod. should hydraulically push the bushing out.

That sounds like a potentially messy solution! I can see how it would work in theory, but I think finding the rod to fit may be a pita, unless you know of something in particular other than the armature shaft. I do like the slide hammer idea, I may have to rig up a setup like that. I'll let ya know what happnens, hopefully tomorrow evening.

never had stuff i need on hand, when i needed it. so have used awe / hammer. due to bore was to small for other stuff i have.
would be intresting to see what ya come up with, and if it works.

i know the stinking anchor bolts can hold up to a sledge hammer. (broke some concrete blocks) a few days ago, tearing out an old window. the flat heads on the bolts were rusted and no real way to get at them. so old sledge and pop the frame of the windows. the anchor bolts won though :/ thankfully no extreme major damage. just bigger holes, that needed bigger anchor nuts.

the armature should fit pretty close

if you have the slide hammer with a hook end with a lip that small it may work too.

hit it with plenty of penetrant first.
