7010 slippage. Power director or torque limiter

I have noticed using my 1980 7010 power director for 4 hrs straight disking when heading home up hill 4 high fast it acts like a truck does when the clutch is worn and slipping. Push button on floor for slow does it also but not as bad. In field disking in 3 low fast up a hill it seems fine.

Thanks cory

Fluid good.
Will check pressure

Yes everything works as it should.

Next time it slips stand on the brakes HARD and make the tractor stop moving. If your power steering quits......it is the torque limiter slipping. This must be done at full throttle.

Look under the bellhousing and see if it is dripping any oil.

You have to completely stop the tractor to test steering.        MACK

....yes because the tq limiter drives everything. If PD was slipping when travel stalled the hyd pump would still work and P/str & hydraulis would function. If limiter slips at travel stall,you are not turning hyd pump so no pwr str or hyd function

I have a feeling that the engine won't stall because something is slipping to cause your original issue?? Does the engine rev up during your "slippage? Sadly, I might be one of those that need a drawing, but I "think" this one I may be on the right track with the engine dying?? Those are sharp looking tractors BTW,hope you can resolve the issue :-)

Check the oil level on the dipstick under the seat with the tractor sitting on the level and after sitting overnite. Check BOTH SIDES of the dipstick.     By your own description you just wrote.... " It just acts like someone pushed the clutch pedal in as I'm discing".   So, did the power steering still work while this episode occurred  ??????  The correct answer to that question is key to a proper diagnosis.

So have you stepped on the brakes to stop forward travel yet? What did you find out?Hydraulics work or not?

2300 rpm in field with plows up I stand on brakes to bring tractor to a halt and power steering does not work.

Get new clutc disk ,belleville washer check rear main seal and what else?

Thanks cory

Yes obviously flywheel forgot.

I tried looking up the pressure plat on agco books got the part number but when I google a new the oem part numbers dont match.

23 spline 12" with 4 pads or with 6 pads?

It's not a 20 spline correct?
