Ford 8830 pto

Have a Ford 8830, that the pro won"t shutoff properly.
When warm it would cycle properly, but when cold it would
take up to 20+ minutes before it would shut off. Revving up the
tractor would stop it quicker. But when warmed up it would
work properly.
Had into dealer , they replaced the break pads the hydraulic
pump ( the pressures were on the low side ), the shaft that the
clutch disc ride on was bad, and replaced. The clutch plates
were replaced, and some other linkages that were worn.
It worked much better, but still could take up to 3 or 4 minutes
to stop running when it was real cold. The only load put on the
tractor was a grain cart, and fert spreader.

A year later, it is now worse. It takes awhile to stop running
((after it is first started) but now it will not always shut off.
Sometimes now , I have to idle the tractor down in order to get
it to stop. But that does not work all the time.
Had it back into dealer. Everything is within range, (all on the
high side) .the only way to get it to work properly, is to restrict
the lubrication circuit. The problem then is that the hydraulic
restriction light comes on. Does anybody have a idea on how
to fin this tractor.
Thanks

What have they done to the valving that controls the PTO? Sounds lie it may be a little sticky.

First off, I hope you don't continue to starve the lube circuit to get the result you want. That would not be good. Second, I don't see how starving the lube circuit would make the light come on. Something is really odd there.

If the pressures are really OK, about the only thing I can think of that would cause this is warped clutch plates. How hard does the PTO shaft turn with the engine off? You should be able to turn it fairly easily with the engine off. If not, you may well have warped clutch plates.

About the only other thing I can think of is not enough end play in the upper PTO shaft, the shaft between the clutch pack and the rear upper gear set. If this end play is not there, that will cause the entire assembly to bind against the input hub.

What kind of oil are you running in it.

The tractor was opened back up, and everything checked out as it should ( according to the mechanic ). And the clutch plates were replaced in the first repair. They did replaced a feed line on the side of the tractor this time. The old line had a 5 mm oriface in it, the new was an 3mm oriface I did"t,t check how hard the shaft turns . I will check that Monday . I am not at home right now, ( at family for Easter).

They checked the valve out quite extensively. Thew were
thinking it may have been cracked, or bypassing somehow.
But they could not find any problem.
