9n,2n starters-are any of them 12 volt??

I put the 2n starter on my 9n. It had worked on 6 volts when I tested it off the tractor, but not after I installed it on the tractor. I then powered the starter with a 12 volt battery and it works good. Rolls the engine over very well. Is it a 12 volt starter? maybe I still have a bad ground?

I found another starter, but the shaft was bent. I attempted to use another armature to make it work and it does, after some modifications. I think that the drive gear is to close to the end flange. Does anyone know the distance that it should be? I have about .48 from the end of the pilot on the flange to the front of the drive gear. Can I lengthen the shaft to get the right clearance? After playing with these starters all afternoon, I did not feel like pulling the 2n starter off the tractor to measure how far back the ring gear sits.

I can't help with the distance thing, but as for your first question, yes there are 12 volt starters available for the early N's.
 
But ya don?t need one. A good 6Vt. Will turn to beat the band on 12Vt. Don?t run it all day 😊
 
I had a BAD GROUND on my 1945 2-N...

Problem removed as per pictures....

Starters don't care if 6V or 12V. Many fellers switch their 6V batteries to a 12V and think that's all there is to do a 12V conversion. A 12V battery will jump a 6V starter fine. I suspect you have another problem like wiring all mucked up. First, are you trying to run on a 12V battery and conversion with your 2N or is it the OEM 6V/POS GRN system? Take the engine block starter pocket with the scalloped hole and lightly clean, mineral spirits works great (charcoal lighter fluid is same thing) and sand the face mounting surface so you have a good bare metal grounding surface. Gently sand, Scotch Brite, Krokus cloth, Emory cloth, #2 steel wool will work. Do not use a powered sanding disc. Clean the surface before mounting starter. Next, ALL 9N and 2N starter motors used a 1-WIRE unit fed to the armature. If you have a 3-WIRE unit with a solenoid, it's wrong -that is an 8N unit. It's important that you have the correct starter motor AND generator while we're at it. If unit is correct for a 2N, don't worry about clearances and lengths. If you are trying to use a Model A, Early V8, or 8N unit, then yes you will have issues. AND, don't waste your time trying to get a 12V starter -it's not necessary. Stay with the OEM 6V 1-Wire starter motor. If you have a 12V switch over job going on, it should have an alternator in place of the generator and the round-can cutout circuit removed. Get "WIRING PICTOGARMS BY JMOR" to see all the correct ways to wire these N's.

I have been attempting to get the tractor back to it's original 6 volt condition.
I will definitely have to clean the area around the starter mounting access hole. Hopefully, this is the main reason for the starter problems.

I had moved the ground cable location and had thought that the problem was resolved. I see that the starter hole will need some cleaning.

Going back to the OEM 6V POS-GRN set up is fine and will work just fine -it has for 80 years - but I seriously doubt your problem is the starter surface not being grounded. Did you paint it? What was like running before? Was the 12V a recent change? I'm thinking it s a wiring issue.

This is a dead tractor resurrection. I had removed the starter and painted the tractor and the starter. After installing the original starter, I could not get it to work. When I tried the motor test, it ran slowly and with a stutter type of movement. The 2n starter was on a parts tractor that I managed to get started using the starter, but only if I jumped it. Tomorrow I will attempt to get this tractor started again.
