D. Ensure that the octi-cam (1) is in the correct
position with respect to the stop screw holes as
shown by (Figure 11).
E. For standard-rotation assembly (clockwise to close)
rotate the body (50) 40 – 45˚ counterclockwise (if
viewing the bottom of the actuator), or clockwise
(if viewing the top of the actuator) as shown in
(Figure 12).
F. Press the two pistons (40) simultaneously into the
body (50) until the piston racks are engaged and
rotate the body clockwise (if viewing the bottom of
the actuator), or counter-clockwise (if viewing the
top of the actuator), until the stroke is completed.
G. To ensure that the piston (40) teeth are evenly
engaged, fully compress both pistons (40) inward
and measure the distance from the edge of the
body to the piston (40) face on each side, shown
as dimension “A” in (Figure 12). If a different value
is obtained on each side, remove the pistons and
repeat from step 2d.
H. Temporarily install the position indicator (19) onto
the shaft (60) to determine whether the correct
stroke is obtained, Verify that the slot in the top of
the position indicator (19) will rotate a minimum
of 4˚ beyond the 90˚ vertical centerline of the
actuator body (50) and a minimum of 4˚ beyond
the 0˚ horizontal centerline of the actuator body
as shown in (Figure 13). If the proper stroke is
not obtained, remove the pistons and repeat from
step 2d. Once the proper stroke is verified, remove
the position indicator (19).
3. End Cap (30, 31) and Spring Cartridge (17)
Assembly, (Figures 14 through 16):
A. For spring-return actuators, insert the proper
quantity of spring cartridges (17) according to the
pattern shown in (Figure 14) (referring to the total
number of springs). Insert spring cartridges (17) as
shown in (Figure 15).
B. Apply grease to the end-cap o-ring seals, using the
recommended o-ring-area grease listed in (Table 2).
Fit the end-cap o-ring seals (14) into the groove in
each end cap (30, 31).
C. Fit the end caps (30, 31) onto the body (50),
verifying that the o-ring seals (14) remain in the
grooves.
D. Insert all end-cap screws (13) and hand tighten.
Complete tightening by following the sequence
indicated in (Figure 16), using torques listed in
Table 4.
