I replaced mine a couple of years ago and used my gas grill to heat the new ring gear and it worked well. Wife won't let me use the oven, after the melted plastic incident.

Tried this today . Worked great , ring gear fell right on . Thanks for the RV4 ride at Oshkosh about 40 years ago . Like you I have built many airplanes , starting with the RV 4 . Enjoy your arcticles in Sport Aviation

You’re welcome. Keep the dream going.

Vic, you're working too hard. Use a torch and focus the heat on the ring gear and it will fall off in seconds. I had great success using the same install technique you described.

I’m not comfortable using a torch around an aluminum flywheel. This is the recommended method.

First, a screw driver is not a chisel and should not be used as one. Second, why not use heat on the ring gear? Heat would cause the ring to expand allowing for fairly easy removal. Such a technique is normal in automotive ring gear removal. kzfaq.info/get/bejne/oMWjmsyFxpnLlas.html

sure, it looks a little easier if you are proficient with the acetylene torch

Perhaps all of you should read Lycoming Service instruction before you engage your keyboard: Service Instruction No. 1141A. This is done IAW with that, as are the many others I have done over the years.Second, if you looked more closely that was a screwdriver that is intended to be used as a chisel. It is solid steel all the way through, and belonged to my father-in-law. It's worked for more years than we have been around. No, you don't want an acetylene torch around an aluminum flywheel.
