Tools Required:

• 

 5/16” Socket Wrench

• 

7/16” Socket Wrench

• 

Snap-Ring Pliers

CAUTION:

 Before any maintenance or repair is attempted, the 

compressed air line to the pump should be disconnected and all air 
pressure allowed to bleed from the pump.

1. 

 Insert the smaller end of the air valve 
assembly (item 1) into center section 
(item 5) until fully seated. Install 
retaining ring (item 6) in groove on air 
valve assembly.

2. 

 Install backup O-rings (item 20) on to 
surfaces of center section (item 5).

3. 

 Slide washer (item 18) and inner pistons 
(item 19) on to ends of shaft.

4. 

 Slide diaphragms (item 21) on to ends 
of shaft. 

5. 

 Install outer pistons (item 22) on to ends 
of shaft.  Tighten to specifi ed torque (50 
lb-in).  Over-tightening could damage 
outer piston.

6. 

 

Install four (4) ball check cartridges 
(item 15) into manifold (item 13). NOTE: 
The cartridges must be installed in 
correct orientation. Align grooves on 
cartridge with ribs in manifold. Cartridge will be fl ush with end of the manifold if installed correctly.

7. 

Install four (4) manifold O-rings (item 16) on to ends of manifold (item 13).

8. 

 Place upper screw boss in manifold (item 13) in-between the fl anges at the bottom of the center section 
(item 5).

9. 

 Place the center section-manifold assembly between two liquid chambers (item 12), taking care to align 
the large bore on liquid chamber over the diaphragm and the two (2) small bores over the manifold.

10. 

 Place in a vise and carefully press assembly together. Take care not to pinch or damage sealing O-rings.  
There should be a consistent 0.05” gap between the center section (item 5) and liquid chambers (item 
12).

11. 

 Fasten liquid chambers (item 12) to center section (item 5) and manifold (item 13) using (22) #10 screws 
(item 10).  Tighten fasteners to specifi ed torque (35 lb-in). Over-tightening fasteners could damage 
center section.

12. 

 Press muffl er element (item 9) into muffl er cavity (near air inlet) of center section (item 5). Hold muffl er 
element in place using one (1) #10 screw (item 10).

13. 

There are two mounting options for the base assembly (item 23). 

14. 

 Install one (1) NPT plug (item 14) into one (1) inlet port of the manifold (item 13). Install one (1) NPT plug 
into one (1) discharge port on manifold.
