9.

Align the holes in the valve nuts (24*) and the slots 
on the stems of the inlet valve poppets (32*). Drop 
the lock wires (25*) through the holes in the valve 
nuts and into the slots in the stems of the inlet valve 
poppets. Pull the lock wires down tightly, and bend 
the ends with pliers so that they cannot be pulled 
back out of the holes.

10. Take the assembly out of the vice so that you can 

move it around for steps 11 and 12.

11. Grease and install the new o–rings (13*, 18*, 103*).

12. Install the new u–cup packing (16*) through the bot-

tom of the air motor base, with the lips facing toward 
the bottom of the pump.

13. Slide the displacement rod (29) down through the 

packings, and lower the air motor piston (34) into 
the air motor base (28).

14. Clamp the air motor upright in the vice by closing 

the vice jaws below the flange.

15. Carefully lower the air motor cylinder (35) straight 

down onto the piston assembly (34). Tighten the six 
screws (9) holding the air motor cylinder to the air 
motor base (28).

Never re-use the old lock wires. They will get brittle 
and break easily from too much bending.

To avoid damaging the cylinder wall, lower the cylinder 
straight down onto the piston. Never tilt the cylinder as 
it is being lowered.
