Just got a 1250 running that I picked up as a parts tractor, turns out it's in better shape than my 1886 & 1455. Anyway the case of the gen gets hot to the touch, seems to charge normally at around 3-5 amps, no noises, turns over good. The case of the motor seems to produce it's own heat around the coil attatching screws, around 130-150 degrees. Is that normal?

Thanks

Actually I have the same issue as well with my 1050. I just had the gen/starter rebuilt, and after I installed it and found that it was still really hot. I called and asked the guys that rebuilt it if that was correct. They said that this do run hot. It charges OK and starts OK now that I have had it rebuilt. \

Enclosed type generators have no cooling fans and therfore are designed to run hot.

Excerpt from: Delco-Remy Motor-Generator Brochure No. DR 9626 states: In-Part:

"Enclosed units are designed to operate at frame temperatures from 225 Degrees F to 250 Degrees F, which is considerably hotter then the hand can stand."

Source: My copy of the 1966 Bolens Service School booklet.

So apparently this is normal. However it also warns about hard starting heat damaging to the starter. Should wait a couple minutes between starting attempts to allow the starter/generator to cool off.
