Reassembly
1.Place the piston rod (29) flats in the vise 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 lower valve 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
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
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.
