5. Lubricate and install the large o-ring (28) on the
outside of the piston.
6. Lubricate the mating surface and install the
cylinder (27) on one of the covers.
7. Lubricate the outer o-ring (28), the inside of the
cylinder (27), the shaft, and the shaft bearings
(23). Then, install the piston assembly (20) in the
cylinder (27). Add more lubricant on the inside
of the cylinder, above the piston, so the piston
moves freely back and forth.
8. Align the second air cover (7) and press it down
over the cylinder and piston. Use a 13 mm socket
wrench to tighten the bolts on each air cover.
Torque to 28–33 ft-lb (38–45 N•m). Torque the
first cover, then the second cover, then go back
and torque the first cover again.
NOTE: Check the shaft to be sure it moves freely
in both directions.
9. Lubricate and install new pilot valves (if removed).
Torque to 100–120 in-lb (11–14 N•m).
NOTICE
To avoid damage to the pilot valve, do not
overtorque.
