Reassembly

1.Place the piston rod (29) flats in the vice with the air motor up.

2.Pull the exhaust valve poppets (26*) into the valve actuator (12), and clip off the top parts of the poppets (shown with dotted lines in the Cutaway View in Fig. 4).

3.Install the grommets (17*) in the actuator (12), place the inlet valve poppets (32*) in the piston, and thread the bottom valve nuts (21*) onto the inlet valve poppets until there are a few threads left before the threads run out.

NOTE: If you thread the valve nuts too far down onto the poppets, they will run off of the threaded part of the poppets.

4.Grease heavily and place the trip rod (31) in the piston, place the actuator (12) in the yoke (13), and place the well-greased actuator/yoke assem- bly in the piston, with the trip rod going through the center holes of the actuator and yoke and the inlet valve poppets (32*) going through the grommets (17*).

5.Thread the top valve nuts (21*) onto the inlet valve poppets (32*) until one thread of the inlet valve poppets is exposed above the valve nuts.

6.Install the toggle pins (15) in the yoke (13), place

the toggle arm (23) ends of the toggle assembly

(M)onto the toggle pins, and snap the pivot pin (16) ends of the toggle assembly into the lugs (L).

7.Measuring with the gauge (Part No.171818), create 0.125 in. (3.18 mm) of clearance between the inlet valve poppets (32*) and the piston seat when the inlet valve is open. See the Cutaway View Fig. 4.

NOTE: Adjust the distance between the inlet valve poppets and the piston seat by turning the top valve nuts (21*).

8.Tighten the bottom valve nuts (21*) securely by hand.

9.Align the holes in the valve nuts (21*) and the slots on the tops of the inlet valve poppets (32*), and drop the lock wires (22*) through the holes in the valve nuts and into the slots in the inlet valve poppets. Pull the lock wires down tightly, and bend the ends with pliers so that they cannot be pulled back out of the holes.

Reassembly CAUTION

Never re-use the old lock wires. They get brittle and will break easily from too much bending.

10.Grease and install the new o-rings (19* and 20*) on the piston assembly (27) and in the groove in the air motor base (28).

11.Grease and reinstall the vee block seal (10{) in the groove in the air motor base (28).
