pfrederi 18,670 #2 Posted June 5, 2020 (edited) Welcome Remove the pin (Blue) You should be using a Clevis pin.. Remove the bolt in the center (Yellow) Look inside after that you should see some larger threads. Depending on age of PTO may be 5/8" NC or 7/8" NC or even 1"NC Get a matching bolt 4 inches or so long. Screw it in to the PTO and it will pull it off the Engine crankshaft. NEVER use any type of gear puller will damage the PTO. Why are you replacing it? If it is noisy bearing they are replaceable. Not working at all assuming you have power then the field coil is suspect ...also replaceable Edited June 5, 2020 by pfrederi 2 Share this post Link to post Share on other sites
