Well, now you know haw my generator question from earlier turned out. Its shot. It was all original and gave good service since 1926.

What is the best way to release the 4 large screws that hold the field segments in place around the circumference of the generator?

Also any other sage rebuilding advice?

What numbers are the sealed bearing eqivalents?

Thanks all, Erich

Without the proper tools and gauges to reset poles in the generator,you will find your efforts/results are less than expected. Box it up and send it to Coilman . You will be very pleased when it returns.

That is dishartenting due to the fact that I just ordered all the parts....Any other thoughts?

Erich

If you don't already have it, get the MTFCA "Electrical System" book. With no experience working on generators, I fixed the one on my '23 touring. All it took was that book and some careful reading. Parts are available from all the usual dealers.

Erich,
You can do it yourself, but you do have to be careful, meticulous, and "enterprising" (to make up for not having the special tools and gauges --like using the drill press, or a press to hold the screwdriver to loosen & tighten the pole screws.)
The book really helps!!

Thanks Steve,

I have that book and it seems to me I should be able to do it. I am incouraged again. Any other input out there?

Erich

You might talk to Ron the Coilman and explain the situation. He may give you an estimate for rebuilding the generator using your parts. My experience has been that the first time I try rebuilding something is a learning experience for the second time I try to rebuild the same item (you might have to do it more than once). I also usually find there is some special tool required to do the job or that makes it MUCH easier. I know the $ amount is different but I think Ron was going to give me credit for the capicators I already had when I talked to him re rebuilding some coils.

Erich:

I can't speak for Ron but before you go any further - at least contact him. His work is so good I will warranty it myself. A really good rebuild is the END of your generator problems but a bad rebuild is the beginning all over again.

I do love to learn by doing. I also have learned it is usually good to listen to the voice of experience. Plus Ron is a great guy so I think Thats a great idea. Thanks again,

Erich

If you want it to last and work efficiently there's more to it than just replacing parts. And there's no way you can put in new field coils and get the poles aligned without the tool. If Ron can't help you, let me know.

Thanks Ken. I just dropped Ron a line regarding my situation. I do get a lot out of doing it myself, but the model T needs all the help it can get in the reliability department. The gen lasted 80+ years. It would be a shame if my redo lasted only a short time due to some "almost right" rebuild issue.

Thanks again, Erich

Send Coilman the parts too, I did. He does great work! I had the parts for 20 years and didn't ever find a way to get those four screws out.

I am a cheapie. I get used generators from swap meets. I try them out and if they work, I use them. Sometimes I can swap parts from one to another and make one that works. The only thing you need a generator for is the battery and lights. I very rarely drive with lights on, so if the generator goes out on a tour, it is no big problem. I have had very little trouble with the used generators I have gottem and they usually cost about $15 each.

Nothing ventured, nothing gained. You can always send it off to the coil man. Its not likely you will wreck anythiing beyond repair. Give it a shot and see how it goes.

Norman - I've never seen a generator for less than $35, good or bad, but mostly bad. I'll take 9-10 of your $15 generators! Three at a time will fit in a large USPS flat rate box.

Save a few of those for me too.....$15.00 is way easy on the budget..

Erich

Eric,I use one of those hand impact tools to get the pole screws out, you may needto grind out the places that they are staked with your dremel tool. I have never had a problem in rebuilding my own starters or generators. Find a shop that can put the armatures on a growler and check them. Go by the book like Steve says, take your time and you can do it, thats what the hobby is all about! Have fun ,KB

Well, my field checks out O.K. for no grounds, no opens, by ohm meter. Armature checks good too. I may be in for a less detailed rebuild than I thought. I will replace all the brushes, contacts, insulators, bearings, pinion gear, etc. and I may be in good shape if I go by the book. Thanks for the well wishes.

The two bearings are 6201-2RS and 6203-2RS. I sent you an email with other rebuild recommendations.

Thanks Ron,

Your help is always welcomed and appreciated.
