For future reference, use a bearing splitter to spread the load over a wider surface of the gear when pressing it off. I consider stovebolt timing gears to be a one time installation piece- - - -it's risky to try to reuse one that's been installed before. The timing gear I'm going to use on my roller cam engine will be honed to be a snug slip fit and retained with a bolt and a heavy flat washer, since I'm planning to tinker with the cam timing with offset Woodruff keys.
