shaped projections of the end cap fit into the ends of the inner guides
4) Insert four end cap bolts with four flat washers through the holes in the end cap.
5) Push down on the end cap, compressing the springs enough to start threading
the bolts into the actuator body.
6) Tighten each bolt a little at a time until the end cap is fully tightened down onto
the actuator body.
7) Torque the bolts as follows:
a) 51.5 in.-lbs. for the 4-inch (smaller) actuators
b) 117.5 in.-lbs. for the 9-inch (larger) actuators
8) Repeat the previous 7 steps for the other end cap.
