When I was restoring my 1958 TR3A from 1987 to 1990, I noticed that my ring
gear on the flywheel had a few teeth that looked a bit feeble, so I bought a
used flywheel from the late Dave Geller, removed the good ring gear and put
it on my original flywheel. I had to warm them up, first to get them off,
then to re-mount the good one on my flywhheel. I have never had a problem
with this new old ring gear in the last 11 years (60,000 miles).
