then unscrew 1.5 turns.
2. Lubricate the inside bore of the body and valve stack
components with oil.

(item 1H) first then Glyd Rings (item 1E, figure 2) on both
ends of poppet set (item 1G, figure 2). Allow the valve to sit
approximately 10 minutes to allow each Glyd Ring to return
to its original position.
4. Insert bushing (item 1A, figure 2) into cavity, taking care not
to misalign the part in the bore. Be sure that orientation of
bushing is as shown in figure 2.
5. Insert O-ring (item 1C, figure 2).
6. Insert seat spacer (item 1F, figure 2) into cavity taking care
not to misalign the part in the bore.
7. Insert O-ring (item 1C, figure 2).
8. Insert poppet set assembly (item 1G, figure 2).
9. Insert O-ring (item 1C, figure 2).
10. Insert seat spacer (item 1F, figure 2) into cavity taking care
not to misalign the part in the bore.
11. Insert O-ring (item 1C, figure 2).
12. Insert bushing (item 1A, figure 2) into cavity, taking care not
to misalign the part in the bore. Be sure that orientation of
bushing is as shown in figure 2.
13. Insert spring (item 1D, figure 2) into valve plug (item 3, figure 2).
14. Screw valve plug (item 3, figure 2) into cavity using a 7/8"
socket wrench until bottomed out. Then, loosen 1.5 turns.
15. Insert set screw (item 9, figure 2) using a 5/32" Allen wrench.
Tighten until flush with valve plug (item 3, figure 2), then
tighten 1.5 turns.
16. Electric valves only: Torque solenoid stem to 15-20 ft-lbs
[20-27 Nm].
17. Air actuated valves only (follow steps a through g):

plug (item 18, figure 2). Torque plug (item 18, figure 2) to
15-20 ft-lbs [20-27 Nm].
b. Insert pin (item 22, figure 2) into plug (item 18, figure 2).
c. Apply Loctite 222 to threads of spring guide (item 25,
figure 2) and install into cylinder (item 20, figure 2).

[,70-,90 Nm].
18. Torque valve plug (item 3, figure 2) to 32-35 ft-lbs
[43-47 Nm].
19. Install three O-rings (item 13, figure 2).
20. Mount the poppet valve (item 41, figure 1) in the orientation
shown in figure 1. Before installing socket head cap screws
(item 42, figure 1), apply a small amount of grease to threads.
Torque to 6-10 ft-lbs [8.1-13.6 Nm].
CONTROL VALVE REASSEMBLY
1. Mount the multi-port assembly (if equipped - items 50-56
and 61-62, figure 1) using five socket head cap screws (item
53, figure 1). Torque to 10-12 ft-lbs [13-16 Nm].
2. On older versions without externally adjustable "B" side
relief valve, install ball, guide and spring (items 36, 37, 38,
figure 1) through the bottom of the body (item 34, figure 1).
3. On newer versions with externally adjustable "B" side relief
valve, install ball, guide and spring (items 36, 37, 38, figure
1) through the top of the body (item 34, figure 1). Then install
set screw (item, 75, figure 1), copper gaskets, jam nut and
acorn nut (items 70, 71, 76, figure 1).
4. Install O-rings (items 44, 45) and mount the manifold (item
