All valve control rods are adjusted basically the same way. This

procedure covers SPRUNG/UNSPRUNG valve control rod.

control lever is in neutral (off) position.

NOTE

Normal control valve plunger travel is 9/32 in. (7 mm).

Remove cotter pin (Figure 8, item 2), straight pin (Figure 8, item 5), and clevis (Figure 8,

item 6) from control valve plunger (Figure 8, item 1). Discard cotter pin (Figure 8, item 2).

Loosen jam nut (Figure 8, item 7). Turn clevis (Figure 8, item 6) clockwise to shorten

valve. Have assistant move SPRUNG/UNSPRUNG lever between SPRUNG and

UNSPRUNG mode. Measure distance of plunger travel.

Adjust clevis (Figure 8, item 6) so plunger (Figure 8, item 1) travel distance is correct

(9/32 in. (7 mm)).

When proper adjustment has been made, coat threads of rod (Figure 8, item 3) with

sealing compound primer and sealing compound. Tighten jam nut (Figure 8, item 7)

against clevis (Figure 8, item 6).
