John Deere B starter question

WaltT · Jan 21, 2022

I am rebuilding my existing starter, but how does the field coil actually connect to the manual starter button?

Does it just sit against it or is it supposed to connect somehow?

Not enough heat was my soldering issue, went with propane torch and solved the solder not sticking problem, starter is now operational.

that brass field end has to be fitting in the slot on the stud. then it gets soldered. but u have things screwed up there.

Thanks for this info about that slotted screw, but besides from being beat up a little, what was screwed up?

you got to get that copper connection straightened out and fitted in the slot. it even looks too short unless u cut it off. i would have got
it in place first then tighten the nut then it would put pressure on the stud making a good contact then solder it.

Your starter should be a 6v 1107942 (mounted under the tractor) or 1107445 (mounted above the fly wheel) on the starters tag (if attached)depending on the tractors model year The leads coming from the coils to the stud need to be seated DEEP in the studs slot and soldered. Usually there is 2 coil leads that fit in the studs slot. You may need to widen the slot for the leads to fit. In some cases the nut is not used on the stud for clearance for the armature to spin correctly. Make sure the bottom of the stud does not extend inside the starter beyond the field windings. There are many variables doing the task you are doing to ensure there are no shorts keeping the starter from operating.

Thanks so much, that makes a lot more sense. I had purchased a 12 volt conversion for my starter (1107942) but it was thicker than the original 6 bolt system, so it did not work. I have the 6 volt coil ordered to replace the original but at least now I know how it hooks up, as my last set of could did not have any info about how that fits.

New coils are in now, but do I solder the long lead to the L-shaped lead to make htis work?

Walt, check out the link below to a recent thread about soldering a starter stud.

It's a different style, but the principle of soldering the field leads to it is the same.

You will also notice the pole shoes have a long lip on one side and shorter lip on the other side. Make sure they face the same way when installing. Hopefully you noticed the way they were facing before removing them. If not you will figure it out.

If I did not notice how these came off, do you know how to determine which goes where?
