Guy says his generator is giving problems making a squealing noise I tell'em to take it to the local Auto electric repair shop. The guy try's to sell him a new gen but its s one terminal gen the guy catches it. He ask if he could repair his old one he tells him he can convert it to 12V...

He brings me the gen all I can see wrong with it is the front bearing is locking up. I split it enoufh to see every thing looks good in it...
Question to get the brush plate off do Y'all remove the post in the brush plate were my finger is pointing.

It looks great for a 49 generator every thing in good shape the armature has never touched the field coils. He said it was still charging...

You don't need to pull the back end plate all apart to replace brushes. CLEAN UP THE ARMATURE AND COMMUTATOR, REPLACE BRUSHES IF WORN AND SINCE IT'S THIS FAR ALONG, REPLACE REAR BEARING AND BUSHING. Typical response from a shop guy who doesn't have a clue on 6V systems. Probably tried to sell you a an 8-VOLT battery too.

Saying it is a '49 generator really means nothing -it is the style that is important. The '48/'49 8N generators were 3-Wire/3-Brush, A Circuit design units with output rated at 11.5 AMPS and used a Voltage Regulator. The earlier 9N/2N, post s/n 12500 generators, were 1-Wire/3-Brush, A Circuit Design units with output rated at 11.5 AMPS and used the round-can cutout circuit. You can use one on an 8N with some minor external re-wiring. I can't tell if you have 1 or 3 wires. Also, don't always think because there is a 3rd Brush adjustment screw that there is a 3rd Brush in the circuit. Many were removed per a Ford 8N Service Bulletin that made your 3-brush into a 2-Brush unit. The only way to be sure is by an internal inspection like what you're doing. The shop guy has probably only dealt with the 1-wire units because that's about all they sell new/aftermarket today. When changing brushes on 3-brush gennys, inserting and reassembling the back end plate is tricky. First adjust the 3rd brush screw to the 'LOW' setting. Some use dental floss or fishing line to tie off the brushes, then when assembled, pull the loose ends thru to remove.

If you can replace the brushes with out removing this post you know sum'M very few know... That stud mounts one of the brushes to the end plate :shock: It comes right out I don't know why anyone would fight it. I don't know why you would need to hog tie the brushes either, with that post out it looks like to me you can install the end plate to the armature and slip it into the housing while feeding that post into the end plate...

Time will tell its apart, parts on the way...

The front bearing put up a good fight I managed to get it off with out breaking anything...

Yes, the terminal posts unbolt easily -access from the inside no problem so what is it you are asking? You are the resident 'shadetree mechanic' so no doubt have done this before.

Very few gens have came my way in my time on this rock. I thought it would be a good time for Y'all 6V lubbers to strut yer stuff... For-sure its not the same old my tractor won't crank, start, cuts off... The last gen I messed with was back in the mid to late 80's On HD's B circuit life was good they had a solid-state replacement voltage regulator...

You typed "You don't need to pull the back end plate all apart to replace brushes."

I took it as that post does not need to come out.

Well it does.

Guess what I discovered... the end plate was covered in dirt when I cleaned it I found were you lubricate the rear bushing. The others I have seen had a oil cup that's a no brainier I did not know it had a place to lube it on this one... I guess you learn sum'N new every day...

Its to EZ to tell someone to haul it off to a electrical repair shop let them work on it for peanuts I recon... I am not gonna get rich at it either :(...
 
" Its to EZ to tell someone to haul it off to a electrical repair shop let them work on it for peanuts I recon"

Yep.

The last time I got that deep in a generator was on my 40 Chevy pick-up, at least 25 years ago. That's when I discovered the magic of generator rebuild shops and money!!!

I tried my best to pass it off but it came back :(... I have sold all my good used starters and gens so fixed up starter and put it on the shelf it was for the luv of it not the money... I spec a gen is such a slow selling part its not worth the time to repair a generator and stock it..

How I made my first million not really but I sure made some good money in the 70's and 80's...

You only needed 3 engines, 3 transmissions, 3 starters, 3 alternators that covered most of the big three applications. You only needed to stock 3 tune up kits, 3 sets of brake shoes and pads. When you were slow you could build engines, transmissions, starters and alternators so when you got busy you had labor stored and ready to plug and play... It was EZ money you can not do that anymore you will get stuck with it and wait till ell freezes over for something to come it that it fits...

In the 90's I probably had 20K in parts on the shelf because it took so long to get some parts. Its not like today when you can get most parts the same day are at the least the next day...

Back to the starter/alt/gen repair shops the local one was dirt cheap I stayed on his arse to buy a new truck and build a new building and charge for his service to pay for them... Well he did and now I can not afford him... :( I am happy for him tho he's done good so good he does not have to work anymore he built his shop big enoufh he rents out to a garage and several other outfits...
 
Assemble the armature to the brush plate feed it into the gen housing while feeding dat terminal into the brush plate EZ as pie no hog tie'N needed... BTW the part number for the front bearing izzz
6203-2RS...
