(320) onto the air cylinder (319). Make sure that
o-ring (318) is in place on the cover. Grease the
o-ring.
15. Align the air port hole on the air cover with the
front of the pump. The hole should align between
the fluid port fittings on the fluid cover (311).
16. Spin the tie rod screws (312), lock washer (304),
and plain washer (322) into the air cover (320).
Tighten in a cross pattern only until snug.
17. Lay the pump on its side to tighten the tie rod
screws (312) in a cross pattern. Torque to 160
in-lb (18 N•m).
18. Attach the air valve assembly (323-326) to the air
cover (320). Tighten so that the air fitting faces
