ASSEMBLY INSTRUCTIONS
HOOK OR LUG SUSPENSION
Models E, H, R, RR, E-2, H-2, R-2 and RR-2.
Assemble the dead end bolt and block through the suspension
adapter as shown in Figure 19.
Figure 19. Hook Suspension
WEATHERPROOF HOIST
Check to see that the control station, gasket, neoprene grommet,
cover gaskets, motor housing and gear housing gaskets are in good
condition and in correct position when reassembling.

GEARING

Models JJ, LL, RR, JJ-2, LL-2, RR-2, RRT and RRT-2 have a special
Liftwheel Gear (627-303) and Intermediate Pinion (627-325).
If the gear train in these hoists is disassembled, the following steps
must be observed in order to properly orient the three parts when
reassembling:
1. Assemble liftwheel gear to liftwheel NOTE: These parts have
their splines keyed in such a way that they will go together only
one way. See Figure 20.
2. To install the intermediate pinion, align the arrows that are
stamped on the pinion and liftwheel gear so they point toward
each other.
3. Check operation of gear train by rotating the pinion four (4)
complete revolutions; liftwheel gear will turn one (1) complete
revolution and the arrows will again be aligned as shown. If the
arrows do not align or there is binding between the gear teeth,
repeat the above steps.
4. For gearing lubrication instructions, see page 15
Figure 20. Non-Circular Gearing

FASTENERS

Models A thru H-2 tighten motor housing screws (627-108) to where
they have a minimum breakaway torque of 48 pound inch and the
brake attaching screws (627-253) have 50 pound inch (5.649 Nm)
minimum breakaway torque.
Models J thru RRT-2 tighten limit switch attaching screws (627-220),
brake attaching screws (627-253) and hexagonal brake stud (627-
265) to where they have a minimum breakaway torque of 50 pound
inch (5.649 Nm). The liftwheel gear nut (627-305) should be tighten
to a seating torque of 85 pound feet (115 Nm).

LOWER HOOK BLOCK PIN

When removing or installing the lower hook block pin (627- 764),
care must be taken so as to prevent damaging the pin and/or hook
block. These pins are tapered groove pins and as a result, they can
only be removed in one direction. To remove the pin, a V-Block, drift
and hammer (or slow acting press) are required. The drift should be
the same diameter as the pin (5/16" (7.94 mm) diameter for Models
A, A-2, AA, AA-2, B, B-2, C, C-2, F and F-2; and 3/8" diameter (9.52
mm) for Models J, J-2, JJ, JJ-2, L, L-2, LL and LL-2), and it should
be placed at the small end of the pin. The small end of the pin is the
end opposite the end on which the 3 grooves are visible. Place the
hook block in the V-Block and drive the pin out using the drift and a
hammer or slow acting press.
To re-install the pin, the parts must be arranged the same as they
were when the pin was removed. To do this, use the small end of
the pin as a gage. First check the holes in the hook block body and
determine which holes is the largest. Place the hook block body in
the V-Block with the larger hole on top. Next, check each end of the
hole in the lower chain block (627-775) and determine which end
is the largest. Place the chain in the slot of the chain and insert the
chain block, with the large hole on top, into the hook body. Align
the holes in the hook block body with the hole in the chain block
and insert the small end if the pin in the hole. Push the pin in by
hand until it stops and then use a hammer or slow acting press to
drive the pin into position so that the end of the pin is flush with the
outside surface of the hook body.
Use of improper lower hook chain block pin as well as improper
installation of this pin can cause the pin to break and allow the load
to fall.
TO AVOID INJURY:
Use only CM supplied, special high strength lower hook chain
block pin to attach the chain to the lower hook block and install
the pin as directed above.

REMOVAL AND INSTALLATION OF LOAD CHAIN

Improper installation (reeving) of the load chain can result in a
dropped load.
TO AVOID INJURY:
• Verify use of proper size and type of hoist load chain
for specific hoist.
• Install load chain properly as indicated below.
USE ONLY CM STAR (H) GRADE LOAD CHAIN AND
CM REPLACEMENT PARTS. USE OF OTHER CHAIN
AND PARTS MAY BE DANGEROUS AND VOIDS
FACTORY WARRANTY.
