install the bearing and washer (keys 4 and 43) into the housing as shown in figure 6 or 7. 5. Secure the mounting yoke to the actuator with the cap screws (key 20). Tighten the cap screws to 25 N m (18 lbf ft) for size 20 and 27 actuators and to 102 N m (75 lbf ft) for size 75 actuators. 6. The index mark on the valve shaft must be aligned with one of the four index holes on the end of the actuator hub (key 6). Consult the appropriate valve instruction manual for lever/shaft index mark (hole) orientations for various positions. Then, slide the actuator onto the valve shaft. 7. Bolt the mounting yoke to the valve with the mounting bolts provided with the control valve. For Type 9500 valves, bolt the mounting yoke to the valve with the cap screws and flat washers (key 36 and 38, not shown) supplied with the actuator. 8. Apply Lubriplate MAG-1 or equivalent lubricant (key 35) to the wall of the cylinder (key 8), to the cap screw (key 19), and to the O-ring (key 17) as shown in figure 6 or 7. 9. Install the spring (key 7). Then, attach the piston (key 3) to the piston rod (key 5) with the cap screw
(key 19) and sealing washer (key 11). For size 20 actuators, install a flat washer (key 23) with these parts. Tighten the cap screw to 81 N@m (60 lbf@ft) for size 20 actuators, 136 N@m (100 lbf@ft) for size 27, and 176 N@m (130 lbf@ft) for size 75 actuators.
Note Before installing the cylinder cover (key 2) on Type 1066SR size 27 and 75 actuators, adjust the travel stop set screws (key 12) for 60-degree rotation using the procedure in the Adjustment section. This adjustment will allow easier installation of the cylinder cover.
10. Install the cylinder (key 8) and the cylinder cover (key 2), for: D Type 1066 Size 75, secure them to the actuator housing with cap screws (key 16) as shown in figure 4. D Type 1066SR, secure them to the actuator with the flat washers and hex nuts (key 30 and 31) as shown in figure 5.
