13. Refer to the appropriate valve instruction
manual for lever/valve shaft orientation marks, and
slide the lever (key 27) into place; see figure 4 for
correct lever operating clearance. Clamp with the
cap screw (key 28, figure 9).
14. Rotate the lever (key 27) to align with the rod
end bearing (key 17). This connection can be aided
by carefully stroking the actuator off its up travel stop
with a regulated air source.
15. Apply sealant (key 77) or equivalent
thread-locking compound to the threads of the cap
screw (key 18).
16. Connect the lever (key 27) and the rod end
bearing (key 17) with the cap screw and hex nut
(keys 18 and 19). Tighten the nut on the cap screw
(see table 3).
17. Coat the bearing surfaces of the hub (key 29),
and cover (key 33) with lithium grease (key 76).
Install the bushing (key 31) and hub into the cover.
Secure with the retaining ring (key 30).
18. Install the travel indicator scale (key 35), and
secure it with the self-tapping screws (key 36). Then
install the travel indicator (key 37), and secure it with
the self-tapping screws (key 38).
19. Note the valve disc or ball position, and direction
of rotation. Position the travel indicator (key 37)
accordingly.
20. Replace the cover (key 33), and secure with cap
screws and washers (keys 34 and 63). If the holes in
the cover and housing (key 20) do not align, use a
regulated air source to move the actuator slightly off
the up travel stop. If hole alignment cannot be
obtained in this manner, temporarily loosen cap
screws (key 23), and shift the housing slightly.

1051 & 1052 F & G Actuators
SIZE 60 AND 70
CAUTION
To avoid parts damage, do not stroke
the actuator while cover (key 33) is off.
21. If a valve positioner is to be used, consult the
separate valve positioner instruction manual for
proper positioner installation.
22. Follow the instructions in the Turnbuckle
Adjustment section.
Changing Actuator Mounting
The actuator is normally positioned vertically in a
horizontal pipeline. However, four mounting styles
and four positions for each style are possible (see
figure 3).
Due to its weight, the Type 1052, size
70 actuator must be externally
supported if mounted in the horizontal
position.
Correct lever/valve shaft positioning is important to
ensure proper valve action. Consult the appropriate
valve instruction manual.
Style A is right-hand mounted, while style D is
left-hand mounted. In all other ways, the styles A
and D are identical.
Style B is right-hand mounted, while style C is
left-hand mounted. In all other ways, the styles B
and C are identical.
Use the following procedure along with figures 8
and 9, for key number references, to convert from
