block (21).
8. Place spring retainer (16) over lower end of displacement rod
(6) and packing spring (15) over spring retainer (16). Place
new piston ball (17) onto piston seat (13) and connect piston
seat (13) to displacement rod (6).
9. Insert cylinder (12) over packings and connect to pump block
(21).
Cylinder gasket (22) and packing spring (18) must be
in plae before connecting cylinder to pump block.
Attention
10. Insert connecting rod (5) through coupling nut (4) and thread
connecting rod (5) into displacement rod (6) (from #11, 155-
559).
11. Hold the air motor piston rod (3) at the wrench flats and
thread coupling nut (4) to secure the pump to the motor (from
#12, 155-559).
12. Using the stanchions, the stanchion nuts (1) and washers (2),
secure the pump assembly to the bottom of the unit.
13. Replace the two halves of the shield assembly . Secure the
two halves to each other with screws and secure the entire
assembly to the plate (11) with the four screws.
