Disassembly
NOTICE
Hydraulic oil will discharge
when hub is removed.
NOTICE
It is very important to record the
measurement of the piston sleeve
position before further disassembly.
Proper piston sleeve position
ensures that the bucket will close
before the piston sleeve reaches
its internal stop. If improperly
positioned, the piston sleeve will
bottom out against the ring gear
causing damage to the gear teeth.
