DISCHARGE VALVES & VALVE SEATS
Disassembly
1. Loosen the 2 (M8)locking nuts about one turn.
2.Then remove the 2 (M8)flange nuts.
3.Grasp the discharge manifold with 3 fingers on the underside and tap with a soft mallet to remove.
4.Valve assemblies will remain withthe manifold. In- vert manifold anddischarge valve assemblies should fall out.
5.Inspect discharge valves for wear of ridges. (Spheri- cal valves must be replaced when worn.)
Reassembly
1 . Place retainer in manifold chamber.
2. Next insert spring into center of retainer
3. Place valve over spring with spherical side down.
4. Next insert the valve seat
5. Position manifold back onto pump.
NOTE: Exercise caution when inserting cylinders into manifold toavoid damaging cylinder
6. Replace flange nuts onstuds and hand tighten both sides. Then torque each side to 125
7. Hand tighten locking nut.
- CAUTION 1 When restarting the pump,checkto see that there
is no cylinder motion as this will cause premature failure of the cylinder
end the cylinders.
PUMPING SECTION BE2
Disassembly
1 . Remove discharge manifold as described above.
2.Slip cylinders out of inlet manifold.
NOTE:Identify cylinders so they will be replaced in their original position. (Front to back.)
3.Remove cotter pin, nut, and washer.
4.Next remove piston retainer, spacer, and piston assembly.
