Actuator Assembly Instructions

ACTUATOR ASSEMBLY INSTRUCTIONS (CONTINUED)
12.Place the rack cap (5) ( Figure 21 ) bore side up on the table and coat the edge of each bore with STP Oil
Treatment. Install the rack cap seals (14) ( Figure 17 ) in the rack cap.
Figure 17.
13.Reposition the actuator on the table mounting flanges down, and the lower tubes facing away from the assembler.
Rotate the pinion shaft to allow 1” of the rack to protrude from the top of the actuator body. Install the rack cap with
the oil port positioned to the left hand side of the actuator opposite the bottom oil port located in the tube cap as
shown in Figure 21. Attach the rack cap to the actuator body using the socket head bolts (22) ( Figure 21 ) and lock
washers (26). Torque the bolts to 90 ft-lb. in the sequence shown in Figure 18.
Figure 18.
14.Reposition the actuator so that the pinion shaft can be rotated with no obstacles. Rotate the pinion shaft to ensure
that the racks move freely. Also make sure that the key ways point 15° past "straight up” toward the rack cap and
15° past "straight down” toward the tube cap at each end of the 210° stroke. If the assembly does not perform all of
these functions correctly, it must be disassembled, cleaned, and reassembled.
15.Re-center the actuator pinion in the actuator body by tapping on one end of the shaft with a rubber mallet. Install the
roller bearing (9) ( Figure 21 ), over the pinion shaft and inner race, and into the actuator body. Repeat this
procedure for the other bearing.
