[AT] Stuck clutch JD 60

[Rupert]

hello Charlie,
	I wouldn't use compressed air as the piston can become a missile if it 
moves suddenly as the air decompresses. Besides the decompressing air 
would spread the oil all over the place.
	I would think the hydraulic pressure would have to be higher than 
combustion pressure to hurt anything. Hydraulic pressure will drop 
almost instantly when the piston starts to move.
