Sorry for this long post, but I am trying to be complete! Developed a PTO issue this past year. PTO was slipping under load and would not stop when disengaged. Replaced a broken pressure regulator spring in the PTO control valve body and now have good transmission pressure but the PTO still slipped and wouldn't stop. So we split the transmission last night. Found the PTO clutch discs worn out and coned, so they will get replaced. The PTO brake band is worn out and needs replacing, but can't get the countershaft bearing support casting & bearing off the countershaft. The snap ring was a bear to get off, so maybe we buggered the front edge of the snap ring groove? We can pry forward on the bearing support casting and drive the countershaft back with a bar and 5# hammer trying to get the countershaft out of the inner bearing race, but when the front of the countershaft/snap ring groove region gets about a 1/3 of the way into the bearing race, things stop and we can't get it to move any further. (We realize we likely have damaged the countershaft ball bearing with the pounding, so we plan to replace that as well.) We drove the bearing support back into place on the countershaft and inspected the snap ring groove edges for burrs and didn't find any. We again tried prying and driving the shaft through the bearing, and again things stopped moving about a 1/3 of the way in. Things are acting like the front of the countershaft is a larger diameter and won't pass through the bearing race. Maybe after 30+ years the snap ring has pushed up a shoulder on the shaft OD and needs to be ground off? Any ideas? We are stumped for now.

To remove front bearing support the countershaft is removed with it. Once the two are remove the counter shaft can be pressed from front support/bearing on a press. To remove/release counter shaft, remove rockshaft to gain access to snap rings and countershaft gears. A manual will describe process in detail. DW

It's been a while but I think another shaft is involved. Use two pry bars alternately side to side.
