(Sheet 5 of 7)ASSEMBLY (cont.)1.Install stop (31), dowel (30) andnew preformed packing (29) inbody (32, Figure 14-108).NOTETo change pressure on springs, spacers must be changed.Spacer 5M3492 is 0.010 inch thick and will changepressure 2.01 psi. Spacer 7M1396 is 0.062 inch thick andwill change pressure 12.5 psi. Spacer 7M1397 is 0.036 inchthick and will change pressure 7.25 psi. Adding spacers willincrease pressure required to open valve and subtractingwill reduce pressure requirement.2.Install six spacers (28), spacer (27), springs (26 and 25)and piston (24, Figure 14-107).3.Install spool (23) and spring (22, Figure 14-106).4.Install new preformed packing (21) in cover (20).5.
