Hoist Disassembly - BRADEN CH SERIES Installation Maintenance And Service Manual

DISASSEMBLY PROCEDURE FOR HOIST
1. Remove the wire rope from the hoist drum and align
the drain plug in the drum with the hole in the support
end plate before removing the hoses and mounting
bolts. After the hoist is removed from its mounting,
clean the outside surfaces.
2. To drain the oil, screw a short piece of 1" pipe into the
larger threads of the drain hole.
3. Use a 3/8" drive extension to remove the drain plug
through the pipe. If the drain holes were not aligned
before the hoist was removed from its mounting, the oil
can be drained through the fill/vent plug in the bearing
support by turning the hoist up on the bearing support
end.
4. Begin the disassembly by standing the hoist on the
end opposite the motor. Tag and remove the hydraulic
hoses that connect the brake valve and the motor
(manifold in the case of a two-speed motor) to the
brake release port.
5. Remove the four (4) capscrews and lockwashers
securing the motor and lift the motor off the hoist.
Remove and discard the O-ring installed on the out-
side of the motor pilot.
6. Remove the sixteen (16) capscrews and lockwashers
(20 in the CH185A and C2H185A models) from the two
(2) tie plates, and remove the plates.
