Hey Brad...I think there was a thread over on ST several years ago by now where a guy was having issues with gear wear and they eventually found the gear on the cam was ground incorrectly. That's IF my memory isn't jacked up. May be worth a search over there just to verify what I recall.

Also, you can change the bushing without a taking it apart. The best bet for that bushing is to just eat the money for the correct bushing tool and buy the undersized bushing. The tool then installs the bushing and sizes the I.D. at the same time and you don't have to worry about the bushing being loose. I fought that for awhile. Then I bought the tool and stopped using the pre-sized bushings.
