Lubricate the housing 18, spring 17, and guide

Service

NOTE: Refer to Fig. 9 for steps 17 to 22.

17. Lubricate the housing (18), spring (17), and guide

(16) with light, water-proof grease. Assemble the

housing and spring into the guide. Lubricate the

pin (19) and slide it into the housing. Slide these

assembled parts into the air manifold (20). Be sure

the pin (19) is aligned with the slot (C, Fig. 8) of

the air valve housing (5) before assembling the

rest of the air valve. Repeat for the other side.

18. Install the o-ring (15) on the retainer (14). Screw

the retainers into both sides of the manifold (20);

they should readily screw all the way into the

manifold by hand. If they do not, the parts are not

assembled correctly; inspect, and correct any

22.Reconnect the motor to the displacement pump, remount the pump and connect the air and fluid lines. Reconnect the ground wire before operating the pump.

misalignment. Now firmly tighten the retainers

(14).

19. Place the gasket (30*), cap (29), and gasket (53)

on the air manifold (20). Check the parts list for

your model for the correct gasket (30*) to use. Be

sure these parts are oriented as shown in the parts

drawing for your model.

WARNING

MOVING PARTS HAZARD

Do not operate without the air motor shield in place. Pinching or amputation of fingers or hands may occur. See MOVING PARTS HAZARD on page 3.

20.To install the shield (27), perform step a or b, as applicable.

a.For Models 220106 and 235525: Install the o-ring (26), lift ring (25), screws (24), lock- washers (23), air inlet assembly, and shield (27). Torque the screws to 12–16 NSm (9–12ft-lb).

b.For Model 237000: See page 22. Thread the tube (83) through the grommet (81) in the shield (27) as much as possible. Install the shield. Install the o-ring (26), lift ring (25), screws (24), lockwashers (23), air inlet fitting (68), and mufflers (76). Torque the screws to 12–16 NSm (9–12 ft-lb). Connect the tube (83) to the fitting (87).

21.Test the motor at 0.1–0.2 MPa, 1–2 bar (15–30 psi) before reconnecting to the pump, to be sure it operates properly.
