Fixing up a 1955 Farmall 100. The generator does not have a label and I don't know the serial #. It's very rusted and I'm
doubting if I should have it rebuilt or try and find a Delco-Remy during that period. If I rebuild what do I put on the label for
a serial #?

Fair chance it is a Delco Remy 1100531 6 volt as used on Farmall 100, 200, 300,400,
350U gas and LP, and 1958-61 Cub LoBoy.

From what can be seen in picture you might be farther ahead to by a rebuilt but you might want to be setting down when they tell you the price. I have a B and I think it is same 6 volt generator and they wanted $250.00 for a remanufactured generator. I ended up putting a 6 volt alternator on it at less than half the cost.

Before you panic, use some penetrating oil on all the brush holder screws
& other fasteners & let it soak for a day or so.

The brush holders look to be in usable condition yet, & a good cleaning on
the rest of the unit should be in order.

Check electricals for shorts to ground & also continuity on field windings
& armature.

Clean the armature with fine sandpaper.

Check bearings/ end bushing for excessive wear.

I always shop Ebay first - sometimes only to get a part number.

Two advertised 6 volt generators both advertised as refurbished:

$99 and free shipping:

https://www.ebay.com/itm/Farmall-IH-M-H-HV-SM-Tractor-Rebuilt-6-volt-Generator-Delco-1100501-FREE-SHIP/132401617563?hash=item1ed3c05a9b:g:g08AAOSwHzBZnIWF


$195 + 18.85 freight:

https://www.ebay.com/itm/Farmall-Case-200B-211B-Tractor-generator-6-volt-Delco-Remy-300-350-400-1100531/231949100528?hash=item36013e65f0:g:AdsAAOSw9ENZpjY7

Then some used units in the $55 to $85 range.

In looking at the TC-52 Parts Catalog for International and Farmall model 100, 130 and 140 series tractors it could be either Delco-Remy part no. 1100501 or 1100531. It appears the only basic difference between the two is the length of the shaft on the front end of the armature as both are three brush units. Something in the location of the generator when mounted on the tractor to align with the pulleys and the drive V-belt which is powered from the crankshaft determines which model is required. The 1100501 has a 1 3/4" shaft while the 1100531 is shorter at 1 1/4". The best way to determine which you have it to remove the pulley and obtain a dimension of the protruding shaft and compare to these two part numbers at your generator supplier if you intend to obtain a re-manufactured generator. When I restored my 1953 Super C generator in 2005 I needed a new armature and brushes in addition to the labor and the total cost was barely on the low side of $100 with the new armature price being $67.50 at that time. The generator part no. on my late 1953 Super C was Delco-Remy 1100501.
You make reference to needing the serial number but what you really need is the Delco-Remy PART NO. as their serial number is related directly to the date of manufacture of the generator by year, month and day. In other words every generator of that part number produced on a specific day will have the same serial number. I discovered that tidbit of information when I did some in-depth research restoring the original Delco-Remy starter and generator on my Farmall 240 in 2014.
Hope this information if something that is useful to you and your restoration efforts, Hal.

Thanks for the detail. I visited JP Tractor Salvage today located in Fredericktown, MO. I was on the quest to pick up several parts including a period generator. He was very familiar with Farmall Internationals...he took a look at my generator and said it was probably the original. Asking about the ID plate, he said some generators did not come with ID plates and the holes in mine were for the regulator...not an ID plate. He simply said to have it rebuilt. I broke it apart tonight and the insides are deplorable...lots of rust. I know a guy who can rebuild it. I think I will soak the parts in Metal Rescue to remove and neutralize the rust before having it rebuilt.

Picked up my generator today. He had to replace the armature due to the bearings carving a notch into the shaft and also had to replace the casing as it was badly rusted. Did a beautiful job...no rust and painted. Unfortunately, I didn't tell him that I wanted to keep the generator period.. When I got it home I examined it and he apparently used an old casing, from probably a Buick that was stamped 12 Volts (he did wired it for 6V). Ugh. My fault for not letting him know. I'll install it and get it running. Very disappointed. https://www.youtube.com/watch?v=pTOx2jUqem0&t=2s

If he replaced the armature and the casing, as well as any of the wear parts, he really didn't rebuild your generator as much as he sold you another rebuilt one. There isn't much/anything left of your original generator. Of course considering how bad it looked, that probably couldn't be helped.

You could use a little spot putty to cover up the 12V stamp, and blend it in. Then nobody would ever be the wiser that it wasn't "period."

What a great idea. The font on the stamp is so small, I think I can just file it off. Thanks.
