sion adapter, as shown in Figure 12.

CENTRIFUGAL MECHANISM
Centrifugal mechanism (624-212) is furnished in kit form
which contains the centrifugal mechanism, spacers and an
Instruction Sheet. The Instruction Sheet provides complete
details on the installation of replacement mechanism.
To install the replacement mechanism, a press-on tool as shown
in Figure 13 will be required. The press-on tool is not included in
the kit, however, it may be ordered from CM – order centrifugal
mechanism press-on tool part number 28598.
When installing the replacement centrifugal mechanism, the
spacer is placed between the rotor shaft shoulder and the cen-
trifugal mechanism as shown in Figure 13. Using a slow-acting
press, apply pressure to the press-on tool and press the mech-
anism onto the shaft until it sets against the spacer. To prevent
damaging the mechanism and/or spacer, the force applied to
the press-on tool press the mechanism onto the shaft should
not exceed 3000 pounds.
FASTENERS
Models WE, WB, WF and WH, tighten motor housing cover
screws (624-106) to where they have a minimum breakaway
torque of 48 pound inch.
Models WJ, WL and WR tighten motor thru bolts (624-140) to
where they have a minimum breakaway torque of 50 pound
inch.
The liftwheel gear nut (624-139) should be tightened to a seat-
ing torque of 85 pound feet.
LOWER HOOK BLOCK PIN
When removing or installing the lower hook chain block pin
(624-764), 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" diameter for Models WB, WE, and WF and 3/8"
diameter for Models WJ and WL) and it should be placed on
