Model T Ford Forum: Forum 2015: More Loose Parts :-)

I realize that T flywheel ring gears aren't press fit, but how loose is too loose? The one i pulled off my flywheel at least required me to pull on it to take it off, this new replacement one, not so much. I would think that by having it this loose, it would put a lot of stress on those puny magnet bolts that hold everything together...Thoughts?

You have to heat and hammer them to install them. I would think that if you were able to pull one off by hand, you got a problem somewhere.

I've never had to heat and hammer one to install it. But I've also never had one that wasn't snug. I haven't had any problems with the 4 I've installed in the last 4 years. Others results may vary!

I've had a new one loose but can't remember if that loose, all I did with that one was loc-tite and several drill and tap locking grub screws around it.

Tyrone,

I've never heard of such a thing.

For what it is worth I understand that Model A flywheel gears have to be heated to install. I have never done one on a Model A but am working on one. Not so much on Model T's. I have never had to heat a T flywheel starter gear to install it and I have lost track of how many T gears I have installed. YMMV.

Most anything but the T would be heat-shrink fit ring gear and tack welded, on any car.

I measured at least 0.012-0.015 in some places, not happy with the way this fits at all. Not sure if i should send it back and order a new one from a different vendor and see what happens, or try to fix this one. Chances are the vendors all get the gears from the same supplier.

Look for burrs where the gear goes on, might be what is keeping it from going on.

Mark, go back and retread his original post and watch the video. His problem is opposite of what you're thinking.

I have never used a new gear. Don't use a starter enough on model Ts. But every original gear I have worked with was a snug fit. No heat, usually no hammer (maybe just a tap or two), but definitely no slop.
Yours is too loose.
Most other cars are heat and shrink to install tight fit. Of course, most other cars don't have magneto bolts to also hold it in place. But too loose would eventually shear those brass bolts.
Drive carefully, and enjoy, W2

I bought a new ring gear recently and it slipped straight on, I don't remember it being that loose though. Haven't gone any further with it so I might check how much clearance I have.

Sometimes Ford used out of spec parts in production by finding a matching part that fit, so this flywheel may have been made too small from start? Or maybe the repro part is wrong, do you have more Ford flywheels to check how it fits there?
I wouldn't put it together with such a loose fit.

Does anyone have the spec? It would seem easy enough to measure both the flywheel and the ring gear and determine which is wrong, if you knew what they were supposed to be.

Frank, I'm not sure about a T ring gear, but over here all that is needed is to heat the ring gear a bit, drop it on, and let it cool. Tack welding is totally not required. The only ring gears that are welded that I have seen were on fly wheel flex plates for automatic transmissions. That being said, that was many years ago. Maybe different now? Dave

David, I agree, a lot of modern ring gears are fitted that way, a few are still tacked, it was old school stuff, I can even remember you could buy ring gear pieces to repair once.
