repeated several times to assure small enough diameter has
been achieved to insure proper assembly.
15. Apply lubricant to inside of (9) tube and carefully slide (9) tube
over the (72) wiper and (71) “W” packing or (76) packing set,
and onto (6) outlet body. NOTE: Once the (9) tube has cleared
the packings, a rubber mallet may be used to drive (9) tube
into place.
16. Apply Loctite nickel anti-sieze to threads of (10) connecting
rods and assemble three (10) connecting rods to (15) inlet
body.
17. Assemble (15) inlet body and components to (9) tube, aligning
three (10) connecting rods with holes in (6) outlet body.
18. Assemble three (12) nuts to (10) connecting rods, securing
assembly. NOTE: Tighten (12) nuts to 60 - 70 ft lbs (81.3 - 94.9
Nm). NOTE: Draw (12) nuts equally together and then tighten.
TROUBLE SHOOTING
No material at outlet (pump continually cycles).
Check material supply. Disconnect or shut off the air supply
and replenish the material. Reconnect.
Material on one stroke only (fast downstroke).
The (21) lower ball may not be seating in the (22) ball seat (see
lower pump disassembly). Remove the ball from the seat, clean
and inspect the ball and seat area. If the ball or seat is dam-
aged, replace.
Material on one stroke only (fast upstroke).
The (27) ball may not be seating in the (28) ball seat (see lower
pump disassembly). Remove (27) ball from (28) ball seat, clean
and inspect. If the (27) ball is damaged, replace. Check for worn
or damaged packings and seals. Replace the packings and seals
as necessary.
Material leakage out of the solvent cup or material appears on
the pump plunger rod.
Relieve the pressure in the pump and tighten the solvent cup
until leakage discontinues. If this procedure does not aid in
stopping the leakage problem, the upper packings may be
worn (see lower pump disassembly). Replace the packings as
necessary.
