763 with bics mounted above your right shoulder. Bucket tilt works fine, but lift spool is stuck in valve body. Machine was loading a dumpster when the bucket dropped to the ground and wouldn't lift after that. About 10 years ago, resealed both tilt/lift spools (valve in machine) memory is a little foggy tho. What could make just the bucket lift spool stick? Tried prying on the linkage with the seat bar down, the linkage moves a little, but the spool doesn't move at all, stuck hard.
my best guess is the detent assy on the back of the lift spool is rusted and stuck. disconnect the linkage, remove the 2 allen bolts on the backside of the lift spool. from the front of the valve push the spool out the back of the valve. inside the detent bonnet there are 2 springs and 4 balls.
