1456 slippage

I got a 1456 that i thought the clutch was bad so i replaced it. turned the flywheel with new disc and pressure plate. i got the clutch adjusted properly. this is not my tractor. well when i got done i started it up and thought id try to make sure it hooks up. i put it in any gear and hold the brakes it only pulls the engine down just a little and my foot is off the clutch pedal. im thinking that it was not clutch issues at all now. i took a pressure test at the bottom of the mcv valve and reads 300lbs when the torque is ahead and back. the tractor slipps whether the ta is ahead or back. i also had adjusted the torque along with the clutch. i talked to the owner and he said that the tractor free rolls down hill with a load behind it. i had every valve out of the mcv valve and the all move easily and no scoring. What else can i try? do you think the torque could just go out that fast? I did make double sure that I do have free travel at the clutch pedal. The tractor acts the same way as it did before i put the new clutch in it. isnt it unusual for the high and low side of the torque to go bad at the same time? im just wondering if i got something other than the torque that bad. Thanks for any help you guys can give me. Joe

Not sure if this could be the case, but I have a hydraulic assist clutch on my 1466. Wondering if this device starts to weaken or malfunction if it could impact the full engagement of the clutch.

Sounds like the TA is hatched.

The rear lock up clutch is out of the TA, as is the one way clutch. Just gotta take it apart again. JimN

When the flywheel was resurfaced was the PPA mounting surface also machined to the correct distance to the friction surface? Pressure Plate Assemblies are usually shipped with spacers under the levers. Did they get removed?

It is unusual for the TA to fail on both sides at the same time. Does the pressure drop off as you shift between high and low? Does it drop off when the clutch is released and the dump valve is pulled open? When the MCV was reinstalled, did you happen to use a gasket for a non TA equipped tractor?

You might check and be sure you bon,t have something wrong in the rearend.Your pressures are OK so odds are that both the low & high side would both fail without one of the 3 pressures being off.

Thats a bit on the high side for pressures but ya can live with them . Like Owen said are you 100% sure that they machined the step on the flywheel wright with a step hight of 1.938 inches . Now i do not know just where ya got the clutch from but here again like Owen said are you sure that ya took out the shipping stops . are you sure that ya got the disc in correctly . Now it is possible that the T/A is total toast . But in all that i have done i have never run across one yet . I have only see one tractor that could walk thru a T/A even with 400 lbs pressure for lock up and it was not a Farm Stock one .

I wonder if some of these guys read your whole statement before they start typing. If the tractor free wheels down hill its over running the sprag and the torque is not locking up. The sprag might be the only thing locking up enough to pull tractor and wore enough to slip. If the torque is left in dd until it slips by that time the sprag is shot also. That is why the torque needs to be used roughly 50% of the time of its life in either dd or in ta.
