A generator queery

The TC-26E Parts Catalog for A and B Farmalls is on the Cub Manual Server - www.cleancomputes.com/Cub/index.html. This should be of some help for you. I have the Owner's Manual, just not scanned and uploaded yet.

Have a look at the parts catalog.

Also, might I suggest that you get the Owner's Manual, the TC-26E and the Service Manual for the A at Binder Books. They have reproductions of the originals and are of excellent quality. I cannot give you any info on the manuals offered here in the market place as I have no experience with them, however the Binder ones are the authentic manuals.

Hope this helps..

Also Bob M, gave you some top flight advice. His wiring diagrams are used by Cubbers and other Farmall enthusiasts regularily.... :-)

I think your wife has a real good idea there. And besides, having a tractor with personal family history is the best kind to have, and it helps that your wife is supportive of it as well. Some would call you a very lucky man indeed!

I would have the Generator looked at and rebuilt if needed (besides just the bushing/bearings) and if you use a full fledged 3 or 4 wire Voltage Regulator (to replace a 2 wire cutout relay and light switch field controller if it had that) you get better control/regulation then using the light switch type control. HOWEVER, if originality is an issue and if it had the light switch type of field control, I would get a brand spanking new switch. If it uses the light switch type field current control (versus a VR) I would either insure the old 2 wire cutout relay is working fine or replace it also. Dont forget to Polarize the new Generator!!!!! !

Many of those Delco bearings n bushings are readily available from generator repair shops or even NAPA.

Hows the ammeter look and work?? If any doubt, I would get a new one.

Hows the Ignition/Kill switch??? Again, if any doubt, I would get a new one also.

The generator ball bearing is available at any starter/alternator shop - the same ball bearing is used in nearly all Delco generators and alternators built thru the mid-80’s – about $10. Likewise the starter shop can press in a new commutator end bushing for you.

Good luck – nothing looks better at a green tractor show than a Farmall!!
