NOTE: The two end castings each have an arrow on

them. Make sure that the arrow points toward the fluid

outlet. The arrows will point up when the pump is

completely reassembled and sitting on its two bases.

21. Reattach the six flatwashers, the six lockwashers

and the six nuts on the six tie rods. Tighten each tie

rod by holding the nut at one end of the tie rod and

turning the other one.

22. Tighten the nuts on the six tie rods alternately in

a criss-cross pattern so that the pump goes together

properly. Do not overtighten.

NOTE: When the tie rods are tight, there will still be

small gaps between the body assembly and the two

end castings.

23. Reinstall the inlet and outlet check valves and

manifolds as described in the reassembly procedure

in the Inlet and Outlet Check Valves Sections.

AIR-VALVE:

(Figure 6)

NOTE: To ease in reassembly, lay the body of the pump

on its side so that the air-valve plug is facing up.

CAUTION: The ball valve must be removed if the

pump is placed in this manner.

NOTE: Two special tools are furnished with the

pump. They are used when removing the air valve.

These are the air-valve plug tool for removal of the

air valve plug and the air-valve sleeve extraction tool

for the removal of the air-valve sleeve.

Disassembly:

1. Remove the air-valve plug (37) from the body of

the pump.

NOTE: Use the air-valve plug tool to ease the

removal of this plug.

2. Remove "O" ring (34) from this plug.

3. Remove the push rod (36) from the air-valve plug.

4. Remove "O" ring (35) from the push rod.

5. Pull out the spool assembly, consisting of the

spool (32) with the five seal rings (43), one air-valve

cushion (29) and the detent assembly (33). Remove

the five seal rings from the spool.

6. Remove the sleeve (31) with the six "O" rings (44)

by using the air-valve sleeve extraction tool.

7. Remove the six "O" rings from the sleeve.

8. Remove the second air-valve cushion (29).

9. Clean and inspect all parts. If any kits are used,

use all parts that are supplied in the kit. Replace any

other parts that are worn.

Reassembly:

1. Place the first air-valve cushion (29) into the air cavity

with the flat side down. Make sure that it is not cocked.

2. Place the six "O" rings (44) on the sleeve (31).

3. Insert the air-valve sleeve wih the six "O" rings

into the air cavity.

NOTE: To ease the process, apply a little general-

purpose grease to the "O" rings on the sleeve.
