Home made puller, center hole is tapped 3/8-16NC and the outer holes are 5/16" on 2-1/2" centers ( 1-1/4" on either side of the center hole ) Two 5/16-18NC bolts thru 1/2" sockets ( 3/8" drive)

Also, see that black collar in the back. That has a set screw ( from the factory with a 1/4-20 locking nut on the top ) to hold it in place. Loosen the set screw and then with punch, loosen the the collar by tapping it. That collar is on an eccentric ( it's obround) and in the tightened position, it keeps the PTO bearing & PTO in place. I'm not sure which way to tell you to loosen it since it depends on who put it together, it can be tightened in either direction. Pick one and if that doesn't work, try the other way :mrgreen:

Have you removed the mechanical PTO? ( that must be done first ) Line up the cutouts in the pulley with the set screws ( tapping on the button with a hammer allows you to slowly put it in position ). Then using a high quality 1/8" allen wrench, loosen the set screws and remove them. Factory send them with TWO set screws in each hole. ( six total )

Thanks Jeff, A picture tell a thousand words. I pulled the clutch off of my 107 it had a broken bolt. I got a doner clutch from parts tractor. Parts tractor bearing is like new and mine is worn so I thought I would swap them. As of now all is back together. Mabe tomorrow I will try your puller. Thanks oldiron29
