Farmall H new starter

RMOMN · Dec 11, 2014

I've posted on this before. I bought a starter off of this site for my H it works great except once in awhile maybe 1 out of 10 starts I have to rock the tractor in 5th gear, I hear a click then it will start. My questions 1) The ring gear is a little chewed up about 1/8" is that normal? 2)I measured the drive on the new and original starter. The new starter the drive is 1/4" higher in the down position then the old. I have tried to contact YT and have not heard back. What do I need to do to correct this?

There is a new style Clutch/ratchet drive for retrofitting (no machining) that fixes the majority of issues. If your starter has a heavy spring between the drive pinion, and the motor *flat wound spring wire) it is the old style. Jim

My 1950 6V H did the exact same thing, so I thought the say to fix it was go to 12V and give it more OOOmph. It did, it starts everytime, no more jamming on the flywheel. Only thing, it really WHAMMMs the flywheel, and that has never caused a problem, it has begun to worry me. No problem, just the WHAMMM! every time. I think something is gonna fail soemtime.

Smoothing the ring gear will help a lot. You can even put a bevel on the side opposite the side the starter gear contacts. Looking at the ring gear from the back the drive gear pushes on the right side of the ring gear teeth. I've done it with a file but a die grinder makes the job go much quicker.

Putting a new starter on a bad ring gear isnt wise just going to get worse if those teeth are bad they wont fix themselves bite the bullet and relace it.

Your problem is the chewed teeth on the ring gear. Ideally you would replace the ring gear, but that involves splitting the tractor and removing the flywheel to cut the old ring gear off. The new ring gear is heated and dropped over the flywheel.

Sometimes you can get away with reaching in through the starter hole with a file, and knocking down the rough spots on the bad teeth.

The reason a few teeth get chewed up is because the engine tends to stop in one place every time it is shut down.

Jim do you have a source for the drive you are referring to. The new starter has the same heavy wound flat spring as the original did?

Mkirsch - pardon my ignorance, and my apologies if this is a dumb question, but is this situation unique to IH engines? I'm assuming that it doesn't stop in the [u:cdd6574cfc]exact[/u:cdd6574cfc] same position each time, but close, right? Is that due to how the engines are balanced?

is there any way to avoid this situation? just curious.

thanks,

a 4cyl stops at one of 2 locations. It bounces back from compression. 6 cyl 3 places etc. Jim

One way to avoid stopping on the same spots is to ride the clutch as it coasts down.

I don't even bother to argue with my Farmalls anymore.
All of them.....I stick the hand crank in and turn the engine a little
before I hit the button.
