I am getting ready to replace a ring gear. I have reviewed the archives but still have two questions:
1. Rather than heat the existing ring gear to remove it, could I simply
cut it in two places with an angle grinder?
2. I read an earlier post by Tom Endy on this subject. He has always
been on my "experts" list. He said"
"One other thing I have done is after the gear is mounted four evenly spaced holes are drilled and tapped through the gear to accept a set screw long enough to anchor the gear to the flywheel. The set screws are then installed with Locktight.
I had a starter gear try to "walk" off the flywheel. It came forward to the edge of the mounting flange and jammed the starter. I was able to affect a repair by tapping it back into place through the starter mounting hole a little at a time as I rotated the engine. I then went around the circumference with a sharp punch and tried to distort the metal in front of it every few inches. So far it has held during the last 4,000 miles".

I had always assumed that the gear butted up to a ridge that determined the correct position but apparently this is not so. When installing how do you determine when it is properly lined up? Seems to me that there is not much time to fool around with this if you are trying to install a hot gear over a frozen flywheel.
Many thanks A'ers
