MAINTENANCE (CONTINUED)
DISASSEMBLY AND ASSEMBLY
The parts illustration and list on pages 12 and 13 show the general
arrangement and name of the parts of the CM Bandit lever hoist.
These should be used when disassembling and re-assembling the
units so that all parts are properly installed.
DISASSEMBLY
To replace the liftwheel or stripper, completely disassemble the
unit: remove the chain (See REPLACING LOAD CHAIN, page 8) and
then remove the following: Cotter Pin (26), Castle Nut (36), Twisting
Spring Housing (20), Twisting Spring (19), Hand Wheel (18), Twisting
Spring (17), Hex Head Cap Screw (27), M6 Hex Nuts (23), Lever
Handle Assembly (15), Cam (16), Change Over Gear or Overload
Assembly (14 or 14L), M8 Lock Nuts (25), Brake Cover Assembly
(13), Ratchet Disc Assembly (12), Disc Hub (11), Lever Side Plate
Assembly (8), Guides (6), Stripper (7) On the gear side, remove the
following: M8 Lock Nut (25), Gear Case Assembly (1), Spur Gear
Assembly (34 or 35), Drive Shaft (2), Drive Shaft Washer (22), Load
Gear (3), Top Hook Shaft (21), Upper Hook Assembly (33).
ASSEMBLY
Prior to re-assembly, check all parts for excessive wear, cracks
and distortion. Replace parts as necessary and then re-assemble
the unit in reverse to the order given above. The cam (16) should
be positioned as shown below (use Figure 9 - Cam and Change
Over Gear) when reassembling. Handwheel (18) should be rotated
clockwise 90° - 135° before being engaged onto the drive shaft
(2) splines. This action will load twisting spring (17). The above
assembly steps should be maintained to ensure the free chain
mode works properly upon re-assembly.
Figure 9 - Cam and Change Over Gear
GEAR TIMING
When assembling gears,
they must be orientated with
the timing marks orientated
as shown. (use figure "Gear
Timing") Note: For 1.5 tonne
units, orientation of pinion/
gear assemblies A and B are
not relevant providing the
timing marks are orientated as
shown and one of each (A & B)
assembly is present.
REPLACING LOAD CHAIN
To replace the load chain, remove the lower hook block and chain
stop from the chain. Move the directional lever to the neutral "N"
and pull the old chain out of the hoist. Feed a length of soft wire
through one side of the chain guide and over the liftwheel until it
comes out on the other side of the chain guide. Attach the wire to
the end of the new chain. Position the chain so that the first link to
enter the chain guide will be an upstanding link and the welds on
all upstanding links will be away from the liftwheel. Pull on the wire
until the chain engages the liftwheel. Turn the free chaining knob,
while pulling on the wire, until the chain comes out of the chain
guide. Pull the chain through and remove the wire. Attach the lower
hook block to the chain that is directly below the upper hook.

RECOMMENDED SPARE PARTS
To insure continued operation, it is recommended that one ratchet
disc assembly (12) for each CM Bandit lever hoist in service, be
kept on hand at all times to replace worn brake discs.
Alterations or modifications of equipment and use of any
parts other than CM Bandit lever hoist repair parts can lead to
dangerous operation and injury.
TO AVOID INJURY:
Do not alter or modify equipment. Do use only CM Bandit
provided replacement parts.
