VCCA Home Forums TECHNICAL - GENERAL Electrical - 6 volt '36 Starter Field Coil question

I understand that the '36 738G Starter is supposed to use 821522 & 523 Field Coils.

My Field Coils wrapping leaves something to be desired and I was unable to find the waxed cloth for re-wrapping. I picked up a new set of field coils which were supposed to be a cross match: Made in Canada 5901-0167 (a LH & RH version with the same PN). Upon closer inspection, the Canada version has about 9 layers in the coil and my old field coil appears to have 12-13 layers. I think the new Canadian field coils would only provide approximately 75% of the torque my old coils, right? I do not think the cross match is correct .... what are the Made in Canada 5901-0167 field coils for? (I am going to return them).

Has anyone re-wraped their old field coils? What material did you use? Would 'Liquid Rubber Tape' work as a coating to prolong the life of the old field coils?

You can get the correct field coil wrapping material from your local starter shop. If they don't have it in stock they can order it for you.

I did ask the local starter shop for the field coil wrapping material, but he did not have any on hand. I did not ask him to order some for me as they had the 5901-0167 Made in Canada replacement coils .... which do not appear to be correct for the '36 Master.

As a side note, I salvaged/reinsulated my old field coils with "Brush On Electrical Tape". This appear to work quite well in 'gluing' down the loose/damaged areas of the wrapping as well as providing a coating over the whole coil. The liquid rubber seemed to soak into the cloth wrapping before setting up. I also applied a small patch of canvas material and additional rubber coating over the area where the origian wrapping was cut (where outer edge of coil contacted starter housing, it had not yet shorted out). Time will tell wheather this is a good repair method.

Does anyone know what starter uses the # 5901-0167 Made in Canada field coils - similar in appearance but fewer windings than the 821522 & 523 field coils?

The starter shop that you visited appears not to be a fully stocked shop since rewrapping field coils is a fairly common procedure. The correct way to restore your field coils is to totally remove the old wrapping material and clean the fields. Then both fields should be rewrapped correctly with the right material. Your fix may or may not work over a period of time, but now your field coils are going to be even harder to rewrap in the future because of the "brush on electrical tape". Many starter shops that do a quality job won't even use that stuff. At any rate, rewrapping the field coils with wrapping material is easy to do. I've done many of them myself since the wrapping material is readily available by special order.

By the way, in case you are not aware, new field coils for your starter are still available as well.

Now come on dog, don't leave us hangin', just where would one find/order the new field coils for the older starters/generators?
And how about the feed through lugs and flat head pole screws?? They taint in McMaster Carr’s catalog or any other fastener supplier on the internet that I can find.

Denny....you are looking in the wrong places...those are speciality items so go to a starter repair shop instead. The field coils, pole shoe screws, the terminal studs, bushings, brushes, Bendix drives and yes, even the armatures for the older starters and generators, are all available through your local starter repair shop. None of these parts are a big deal and some starter shops even stock a few of the parts above. If they don't, they can order the parts needed from their supplier.

:) :grin:

Thanks JYD, I was just refering to the pole shoe screws at McMaster, obvously they wouldn't have specialized automotive parts.
Things must be a little better out there on the west coast, our local (Chicago suburbs) starter/generator repair shop is the only one that I know of that's left out in this area. I stopped there a few months ago to get a new brush cover/strap for a standard Delco AD starter. All they could come up with was an old heavly rusted bent up strap off the scrap pile. Tried to get a set of heavy duty fild coils from them, also NG. Taint like it used to be in the good old days good buddy!
If there are any electrical parts suppliers still around I would think they would use the net to market their products but I haven't found any there either. I had several sets of field coils and a half dozen screws and lugs left over from a few years ago but the guy I used to get them from is gone now. It would be nice to find a new supplier.
I'v got the same problem with water pump rebuilding kits, they dried up also, wish I would have stocked up one some of them back when I worked as a parts man for Chevy.

Actually, the parts you were looking for, like the cover band and the pole shoe screws for example, are readily available. The starter shop that you checked out could have ordered the heavy duty field coils and the cover band if they wanted take the time to do it. In fact, they get their parts from the same suppliers we do out here on the West Coast. You would be surprised at the parts that are still available for the older starters and generators.
