OK l am about to receive my new starter ring gear and ask, do they slip on the back of the flywheel and the new brass bolts centre OR do l need to heat to fit??
I've never had to heat a T-ring gear to install it. They slip on and the screws secure it.
David, Tom is right but did you order new bolts Too??
Yes, the bolts need to be replaced every time. They are peened over to secure them. The ends must be ground off to remove the bolts.
The reproduction ring gears currently being sold have 1/4-24 threaded holes for the magnet clamp screws.
Both 1/4-24 and original thread 14-24 screw thread clamp screws are available. Be sure to get the correct screws.

Thank you, l did order the brass screws that were mentioned for this starter ring gear.
The ring that's in there now is missing 5 half teeth, funny thing, it always seems to be at the compression stroke where they go missing, must be hard for the poor little starter motor there.
The ring that is in there now is split between two screws..
David, all the wear is concentrated on a couple of areas on the ring gear since that's where the engine stops after shut down. It'll stop at compression on either #1 = #4 or #2 = #3 then possibly twist back some. You may keep on using a worn ring gear where some of the teeth are still there if you make a habit to move the car in gear somewhat before starting every time, but with a "T" that doesn't make sense since they're so easy to crank start = no need for a starter.
Or take your old gear and rotate it on the flywheel and get some more use out of the old gear.
Question! Do you still have to remove the engine to 'rotate" the ring gear or can you do it while it is still in the car?
You have to remove the transmission from the crankshaft in order to be able to remove the brass screws to rotate the ring. So yes, the engine should be removed.
Be careful removing the starter. The bendix drive and spring must be removed so you don't damage the magneto ring coils.
Some of the Repro Gear's are made with too big of I.D..
The I.D. should NOT have any movement on the flywheel.
If it does, then the pressure of the ring gear is resting on the brass screws rather then the flywheel, and the starter will create movement of the ring gear. It can loosen brass screws.
