1. Remove the wire rope from the cable drum and
rotate the drum until the drain plug is facing down-
ward.
DO NOT
remove the motor hoses or hoist
mounting bolts until the drain plug is in the proper
position. After the hoist has been removed from its
mounting plate, thoroughly clean all the outside sur-
faces. Drain the oil as described in "Preventive
Maintenance".
2. Place the hoist on a stable surface with the motor
facing up. Use support blocks to limit damage to the
sight gauge and vent plug.
3. Tag and remove the hoses connecting the brake
valve to the motor and brake release port.
4. Remove the capscrews and washers securing the
hydraulic motor to the hoist. Lift the motor off the
hoist end plate. Remove and discard the o-ring that
seals the motor pilot.
5. Remove the capscrews and washers from the tie
plates, and remove the tie plates.
HOIST DISASSEMBLY
A typical hoist with a -01 cable drum and auxiliary
brake assembly weighs approximately 1,400 lbs
(635 kg). Ensure your lifting equipment is of ade-
quate capacity. Attempting to lift the hoist with inade-
quate equipment may result in personal injury or
damage to the hoist or property.
BRADEN recommends that the motor
ONLY
be
removed from a hoist positioned on end as described
above. A thrust washer located behind the input sun
gear may become displaced if the motor is removed
from the hoist while in a normally installed horizontal
position, and the over-running brake clutch and input
sun gear are allowed to slide out of position with the
motor. A displaced input sun gear thrust washer may
cause catastrophic gear train failure that could result
in property damage, injury or death.
A hydraulic gear motor and brake valve assembly
weighs approximately 120 lbs (54 kg). Use the prop-
er precautions when handling these parts to elimi-
nate the possibility of component damage or person-
al injury.
