541 Loader/backhoe clutch drags at working temperature

When first started shuttle, dual range & 4-speed shift fine. The longer I use the tractor the more the clutch drags when shifting. I have some grease in and behind the pilot bushing. The clutch disc or pressure plate isn"t hot from slipping, just normal engine heat etc. It shifts decent hot at idle speed (pressure plate is rattling when depressed at idle speed). Set engine at 1500RPM and gears won"t slow down to shift. Not even the synchronized shuttle. The synchronizers will drag & try to move the tractor but not stop the gears. The input shaft has twisted splines behind clutch hub but I think the disc is floating OK. I do have a replacement used input shaft for next split. I"ll probably split it this winter.
Anything I maybe missing?
thanks, Dennis....
 

Dennis,

Are you sure you have the release sleeve

on right, it goes with the bearing to the rear.

you have to know the SN on that series of tractors, later serial numbers had a conventional cross shaft and throwout bearing, that type went together in a conventional manner, bearing toward the fingers. The early, the throwout yoke that you are refering to goes with the bearing toward the yoke (rear). mEl
 
Hi,
Approximate ser# 6165268. It has the early ball pivot & fork. Release bearing would look backwards to a truck mechanic. Coil spring holds solid end against pressure plate fingers (spins with pressure plate). Bearing end towards fork (Free travel end).
I was pushing dirt yesterday and it works great for the first half hour or so. The seal between torque tube & 4-speed has failed so I"m running the rear overfull to keep torque tube full for now. SAE 90w in both. I"ve wondered if the 90W could hide the problem when its cold. The allen head drain plug is also removed (allen head above torque tube drain plug). I"m assuming the allen head is to keep oil in the boxes on a steep grade.
I think you guys would say it works perfectly cold.
Thanks for helping me, Dennis...
