Handwheel to Bracket Assembly
The handwheel is always installed on the same side of the
bracket as the actuator . To install the handwheel assembly,
proceed as follows:
A. Insert handwheel shaft (41) through appropriate
bracket hole and onto lever arm (37) and install clevis
pin (39) and retaining clips (40).
B. Install handwheel bracket (42), lock washers (44) and
capscrews (43) and tighten firmly.
C. Rotate the handwheel subassembly onto the shaft
(41) far enough to allow alignment of the holes in
the handwheel pivot (46) to align with the hole in the
hand wheel bracket (42) and install pivot pins (45)
and tighten firmly.
D. Rotate the handwheel to the disengaged position.
Note: The disengaged position is achieved when the
handwheel shaft is fully visible in the slot on the end of
the handwheel.
E. Connect an air supply to the actuator and apply 20
psi of air pressure to fully extend the actuator shaft.
F.
Rotate the handwheel until the groove in the lever
arm (37) just makes contact with the lever arm pin
(36).
G. Measure the distance as shown in Figure 24 and
install handwheel stop subassembly as shown in the
Reference Table of Figure 25.
Note: Install stop collar (75), spacer (73) and stop (74) in
the correct orientation and secure cap screw (72).
H. Install end cap (51).
I. Replace bottom cover (19). side covers (56) and base
cover (28).
Minor Adjustments
In some instances it may be required to shorten or lengthen the
rod end bearing (94) to obtain the shut off desired, espe cially
with lined valves. Simply loosen lock nut (93) and holding the
actuator stem on the flats provided, rotate the shaft to extend the
shorten rod end bearing (94) then re-tighten lock nut against the
actuator shaft.
CAUTION
CAUTION
WARNING
DANGER
Extension of the rod end bearing is limited to approxi-
mately 3/8” using this method for adjust ment. Further
extension could prevent sufficient thread engage-
ment for satisfactory performance. Should more
than 3/8” be required, lever (33) is not on the correct
shaft spline. Refer to the appropri ate Section of this
Instruction and change as required.
