13. Clean and inspect all parts. Inspect displacement rod's (6)
and cylinder's (12) chrome for grooves, dents or worn areas.
Replace if hard chrome is damaged. Inspect valve seats and
replace if cracked or worn.
Reassembly Procedure
1. Insert upper packing set (19) into pump block (21).
Peak of "V" packings must point upwards on
reassembly.
Attention
2. Insert upper spring (18); small end of spring must go toward
the packing set.
3. Insert spring retainer (16).
4. Place new lower packing set (14) over piston seat (13).
Peak of "V" packings must point downward on
reassembly.
Attention
5. Replace spring (15), spring retainer (16) and ball (17) on piston
seat (13).
6. Thread piston seat (13) back onto displacement rod (6).
i
use Loctite (Part # 426-051) on clean threads.
7. Insert displacement rod (6) assembly through upper packing
set (19) in pump block (21).
8. Place O-ring (20) on end of cylinder (12) and thread back into
pump block (21).
i
Lubricate all O-rings before assembly (EasyGlide,
Part # 0508619).
9. Insert new ball (11), ball cage (10), and new Buna O-ring (9)
into foot valve (7).
Ball cage pin (10a) to be in lower position unless
i
pump is to be used for heavy block filler, roofing
materials or inorganic solvent-borne zinc coatings.
10. Place new Teflon O-ring (8) on cylinder (12) and then install
foot valve assembly (7).
It is not necessary to overtighten foot valve and
i
cylinder into pump block. O-ring seals perform
sealing function without excessive tightening. Full
thread engagement is sufficient. The foot valve
(7) may be rotated back up to 3/4 turn from full
engagement for convenient hose position.
11. Insert connecting rod (5) through coupling nut (4) and thread
connecting rod (5) into displacement rod (6).
12. Hold the air motor piston rod (3) at the wrench flats and
thread coupling nut (4) to secure the pump to the motor.
13. Using the stanchions, the stanchion nuts (1) and washers (2),
secure the pump assembly to the bottom of the unit.

14. Replace the two halves of the shield assembly (10). Secure the
two halves to each other with screws and secure the entire
assembly to the plate with the four screws.
15. For siphon hose attachment, it is critically important that the
thread of the siphon hose fit snugly into the foot valve with
the hose assembly couplings Teflon-taped and sealed to
prevent air inlet leakage.
