Starter: Rebuild or Purchase

The starter on my Farmall 100 has given up the ghost. Opinion: Should I attempt to rebuild or purchase an after market for approx. $110 ?
 
pretty hard to tell when we cant see the old starter. could be as simple as a set of brushes and bushings.
 
I have had good luck replacing brushes cleaning he commutator and bearings but if the armature is shot different story

There was a large posting on this identical subject not long ago in Farmall-IH section.
IMO better to rebuild if your starter is rebuild-able. Many of the new ones are made in China and real junk.
 
They are nothing more than an electric drill motor on steroids. Three common issues: Broken drive pinion/mechanism (new improved style is available), worn out bushings controlling the centeredness of the armature, and worn out brushes. We can help you rebuild it, or find a real Auto Electric shop. Here in St. Cloud MN, that would be Red's Auto Electric. Jim
 
I would rebuild over buying any day if possible.

If not comfortable doing it, send to someone that is referred here.

@Jim, does the improved starter drive fit this starter?
 

Johhny, I had my 450 starter rebuilt twice this year, (both times my fault, or helper). While I cant say it was cheap I can say it was done correctly and with a couple days turn-around. They were also free with their information, which helped me a lot.
I toyed with a used/salvage starter, but decided the chance of getting one as bad as mine, or worse, wasn't worth it.

I don't "get" electrical (you cant fight what you cant see) so doing it myself didn't seem like an option I wanted to try.
Good luck
 
I had my starter repaired for $50. He made a mistake and I returned it. There wasn't a charge for the second repair.
 
Rebuild the one you have.

Don't forget the brush springs. If they have been overheated they will lose their tension. An inexpensive part to replace as long as it is all apart.

I have had good luck with Auto Electric Specialists in Minnetonka.

I've had some experience with those $110 aftermarket starters. Please, rebuild the original if at all possible.

The end cap was cracked on mine so I went for a '' new '' one. Less than one year later I ended up taking the end cap off the new one and put it on the old one.........

I disassembled the starter and hopefully you can see the photos (I seem to have trouble getting them to upload.) The armature looks good, no burn spots or pits. No movement in the bearings, brushes are worn, but still have some wear on them. The field coils are dirty and look awful (but not sure how clean they need to be). I did get some sparks from the exterior switch on my last attempt. It looks pretty simple...can believe that's the problem. ID: # 1565 (letters INH below I think). On the armature is the word stamped "REBUILT" and the numbers "818002." My email is [email protected] if you can't see the photos.
 
Measure the bushings in several directions across their diameter. .oo2" max is OK. Pur new brushes in it, Make sure the
springs are good. Polish the commutator bars (round and round only) with 400 grit. Put a dab of grease down the end frame
bushing. and on the other bushing. Not excessive!!. Blow out the crumbs and try it again. Jim
