Ford 1710 PTO

I have a problem with the pto not staying engaged. I replaced the bearing and seal, everything went back together fine. With the engine off the pto shaft will turn either direction. I can engage the pto and turn the shaft only one direction. Then start the engine with it engaged and it will work for about 5-10 minutes. The pto will handle is still up and if I disengage the clutch and try to engage the pto and it will barely engage and then pop out. If I lift the mower the pto will engage and stay engage. There is no movement back and forth with the shaft and about a 1/32 movement up and down.
It is a Diesel 12/4 gear 2wd synchro. The pto speed is set by the rpm I don’t know if that’s multispeed. I have a service manual and I cannot find anything on this type of problem. The shaft slide’s in with a slight turn and fits into a pilot bearing it the rear. Can anyone help me with this?

i'd check the engagement collar and fork and make sure it is actually fully engaging the pto..if there is a detent, and I imagine there would be.. check that as well.

Ok found the problem. There is a spacer on the end of the PTO shaft that will fall off when removing the shaft. The upper case under the seat has to be removed to install the spacer. Removing the upper case is not hard to do it's just there are several bolts and nuts holding it it place.
