1Open prime valve, (ref# 34) in order to release pressure from the material side of pump.
2Remove pressure control knob, (ref# 74) and pull P.C. stem, (ref# 77) out to internal stop, thereby releasing hydraulic pressure.
3Disconnect outgo tee, (ref# 33) from outgo swivel, (ref# 30) on the outgo valve.
4Remove outgo valve from machine by turning counter clockwise.
5Invert valve and secure upper part of valve, (ref# 29) in vise.
6Remove lower half of valve, (ref# 23).
7Remove crush washer, (ref# 24), seat, (ref# 26), ball, (ref# 26), cage, (ref# 27) and spring, (ref# 28). Clean and inspect all parts for wear. Replace any worn parts.
8Apply Teflon tape to threads of outgo upper body.
9Place spring, large end first, into outgo body. Spring should fit into slot machined into tunnel.
10Place cage onto spring, with open end up.
NOTE: Cage should be open so that it drags down the sides of the tunnel during installation. If closed too much it will trap the ball and cause pulsation in spray pattern.
11Place ball into cage.
12Install seat, beveled side down to ball. Seat should fit snugly into outgo body. Press on seat to ensure it will compress until it is flush with outgo body. Release slowly to ensure the parts do not dislodge themselves.
13Place crush washer on seat. Replace crush washer if badly crushed.
14Thread outgo lower onto outgo upper until finger tight. Tighten 1/2 turn with wrench. NOTE: Teflon tape or pipe sealant should be used.
15Attach repaired valve to machine, installing a new crush washer, (ref# 21) following steps
SPECIAL NOTES:
♦To check the ball for wear, place against a new seat and check sealing edge against a bright light.
♦A used seat may be checked in a similar manner using a new ball. Replace used part if light pass at sealing edge.
