This is required to ensure the shaft (19) is shouldered on
the shaft bearing (8) and to ensure free operation of the
valve.
M.
Loosen lever capscrew (49) and slide lever (34) so it will
shoulder against the shaft bearing (8) and tighten capscrew
(49).
Note: if the actuator cylinder (38) has been removed
proceed to step N. If it has not, proceed to Section 11,
Actuator Stem Adjustment.
N.
Determine the desired actuator action and replace actuator
cylinder (38) on the yoke (33) and secure in place with four
capscrews (36) and lockwashers (37).
O.
Proceed to Section 11, Actuator Stem Adjustment.
10.3 Handwheel Reassembly
A.
Place the valve so the position cover (11) is up.
B.
Remove Truac ring (50) and handwheel washer (51) from
the handwheel powerscrew.
C.
Insert handwheel powerscrew with lock (52) in place into
the appropriate hole in the yoke and screw in clockwise.
