Tom, I assume you mean the Torque Amplifier.
There are three clutches in the tractor. A master clutch that is on the Flywheel, a TA clutch in the front of the TA unit, and behind the Master clutch, and finally a One way "sprague clutch" on the rear of the TA unit. Any of these can slip.
If the tractor slips its engine speed to ground speed in direct, or TA reduction, and if it has gradually gotten worse, it is probably a master clutch. A worn out TA clutch and a bad One way clutch combined will also slip.
If the slippage occurs only in direct (TA forward) and when it slips it seems to still pull as though it was in TA reduction, It is probably the TA clutch.
If it only slips when the TA is back, Reduction, and when it does it seems to just go into neutral instantly, or sometimes won't go into TA, just seems as though it is in neutral, it is the One Way clutch.
All of them require a split of the tractor, and (if it were mine) I would replace them all as well as their throughout bearings and pressure plates.(not on the One Way, it has none)
Hy Capacity company has quality parts. As does Kevin Meier Who frequents this site. Jim
