Disassembly And Assembly - CM HURRICANE 5600 Manual De Funcionamiento

Using any grease or lubricant on the braking
surfaces will cause brake slippage and loss of load
control which may result in injury and/or property
damage.
TO AVOID INJURY:
Do not use any grease or lubricant on braking
surfaces. The brake is designed to operate dry.
When the hoist is disassembled for cleaning or repairs,
the following locations should be lubricated with approx-
imately 1 oz. per hoist of Molykote BR-2-S (Dow Corning),
Molytex #2 (Texaco) or TopMoly (Topsall) grease or equal
lubricant: gears, exterior of drive shaft, internal thread of
brake hub, surface of liftwheel bushings (1/2 ton unit),
bushings in the gear side plate and gear cover, internal
and external surfaces of handwheel bushings and rim of
handwheel cover. Be sure to thoroughly clean the old
grease from these parts before re-lubricating.
IMPORTANT: To assure long life and top performance, be
sure to lubricate the various parts of the hoist using the
lubricants specified above. If desired, these lubricants can
be purchased from CM (See Figure 8, page 8).
REPLACING LOAD CHAIN
To replace the load chain, remove the lower hook block
(656-17) from the chain. Disconnect the chain from the
loose end connector (656-7) and operate the hoist in the
lowering direction to run the chain out of the hoist. Feed
a length of soft wire up and over the liftwheel. Attach
the wire to the new load chain so that the chain will be
entering the center of the hoist frame. Position the chain
so that the first link to engage the liftwheel is an
upstanding link and the weld on all upstanding links will
be away from the liftwheel. Pull on the wire until the
chain engages the liftwheel. Rotate the handwheel until
the chain comes out on the loose side of the hoist.
Attach the chain to the loose end connector and attach
the lower hook block assembly to the other end of the
chain so that the lower hook is directly below the upper
hook.

DISASSEMBLY AND ASSEMBLY

The parts list and exploded view on pages 12 and 13
show the general arrangement and name of the parts of
the CM Hurricane Hand Hoist. These should be used
when disassembling and reassembling the hoists so that
all parts are properly installed.
1. To inspect or replace the brake disc, it is necessary to
partially disassemble the hoist. Remove the hand-
wheel cap (656-36) and the handwheel cover support
(656-35). Lift off the handwheel cover (656-34) and
slide it down the hand chain (656-31). Lift the hand
chain out of the handwheel (656-27) pockets.

WARNING
Remove the handwheel nut (656-30) and driver (656-
29) from the drive shaft (656-10). Remove the hand-
wheel (656-27), handwheel bushing (656-26) and
brake spring (656-25). On the 1 and 2 ton units,
remove the brake hub (656-24) and replace it if the
friction surface is excessively scored. Check the friction
surface of the brake plate (656-22) and replace it if it is
excessively scored. Examine the brake disc (656-23) for
wear, scoring, glazing and contamination. If the brake
disc is worn down to a thickness of less than 1/16 inch
or if it scored excessively, glazed or contaminated with
foreign matter, replace it with a new disc. On the 1/2
ton unit, the brake disc is bonded to the brake hub
(656-24) and as a result, it will be necessary to replace
the brake hub if the brake disc has to be replaced.
After the brake disc is inspected or replaced, reassem-
ble the hoist in reverse to the order given above and
adjust the brake (See BRAKE ADJUSTMENT, page 7).
2. To inspect or replace the liftwheel, chain guide or strip-
per, it is necessary to disassemble the hoist. Remove the
load chain (See REPLACING LOAD CHAIN, above) and
then remove the handwheel cap (656-36) and the
handwheel cover support (656-35). Lift off the hand-
wheel cover (656-34) and slide it down the hand chain
(656-1). Lift the hand chain out of the handwheel
(656-27) pockets. Remove the handwheel nut (656-30)
and driver (656-29) from the drive shaft (656-10).
Remove the handwheel (656-27),handwheel bushing
(656-26) and brake spring (656-25). Remove the brake
hub (656-24) and brake disc (656-23). Remove the
handwheel side plate (656-9) and the two spacers
(656-21),and slide out drive shaft (656-10). Remove the
stripper (656-6) and chain guide (656-5). Examine the
stripper, chain guide, liftwheel (656-8) and loose end
connector (656-7) for wear and damage.
If the stripper, chain guide and/or loose end connector
are worn or damaged they should be replaced. If the
liftwheel is not worn or damaged, reassemble the hoist
in reverse to the order given above. If the liftwheel is
to be replaced, continue to disassemble the hoist.
Remove the gear cover (656-1), end covers (656-4) and
gears (656-12). Remove the snap ring from the lift-
wheel gear (656-11) and remove the liftwheel gear.
Remove the liftwheel and replace it. Check the gears
and other parts for excessive wear, cracks and distor-
tion. Replace parts as necessary and then reassemble
the unit in reverse to the order in which it was dis-
assembled. Adjust the brake (See BRAKE ADJUSTMENT,
page 7) and install the load chain (See REPLACING
LOAD CHAIN, above). After the hoist is completely
reassembled, it must be tested for proper operation
(See TESTING, page 8).
3. To replace hook latch, grind off head of rivet and
drive it out. Remove and discard the latch and spring.
Attach the new latch and spring using the roll pin
provided in the latch kit.
