I have a Massey Ferguson 14 HP tractor that I did "refresh" on 2 years ago/ I paid approximately $1600 to have the K321 rebuilt. That includes a lot of new parts and machine shop work. I have since been told that is way too much money for a rebuild. That may be true, I don't know. I spent the money and I am satisfied with the results and I am not going to dwell on the past. It's over, I can afford it. I'm not worried about it. There is an old saying around here...."Those that can do, those that can't, pay those that can." I am not worried about it. Now for my question. In my younger years (20s) I rebuilt a couple of small block chevy engines. They are pretty straight forward, nothing unexpected, and the engines were still running the last time I saw them. My point is, I do know how to use my hands and standard tools. I now have a chance to buy a K321. I would like to rebuild it myself. Are special tools required to uninstall or reinstall the balance gears or governor. Small block chevys don't have any of this stuff. If special, expensive tools are required, I will probably pass. I don't want to spend a lot of money on tools I will only use once. I have a mic, feeler gauges, torque wrench, and all the other regular tools a person might have. I know I may have to buy or borrow a ring compressor. I have watched you tube videos, but I have never found one that shows installing the governor or balance gears. Thanks for any help. Greg
