Torgue amplifier 8111

Yes, set pressure at 12 bar at 1500RPM and expect it to go to max 14 at 2200
Your parts diagram is different from mine, maybe a later tractor.
I think part 5 is crownwheel gear for the planetry gears whose holder is part 12, all part of the TA

As i said the tractor before i split it goes ok on lo speed and when i put it on hi speed, it goes, but for while and back to lo speed. If the plates in the drum of the TA is worn, i think the tractor will not work on lo speed.If they are wotn i think the tractor will stay.Before i split it i goes uphill with 9 tons lorry and it goes with no problem.
What do you think. Have i to chech the plates or to put the new pump, and to beleive that the problem will disapear.

Had this problem. When garage split tractor they found wear on the inside of a bushing which was allowing the oil to escape under presure, hence pto and torque problems.Perhaps someone here with more knoledge coul describe parts better. Torque pump was fine. After fiz pto brake is still not perfect. During the diagnostic stage we removed one plate from pto pack as garage thought they were tight. could this contribute to lack of break.

This that you said should be behind TA pack, which press the Drum with plates.I must remove pack with plates. When I remove tha plates, on the pack there are big circlips, are they under pressure or not. Is it easy to assemble then it?
