Displacement Pump Service
Reconnecting the Displacement Pump
NOTE: Before connecting the displacement pump to
the motor, check that a new copper gasket (39) is
inserted in the outlet housing (18).
1. Place the displacement pump in a vise, with the
jaws on the pump cylinder (101). Position the air
motor (1) so the displacement rod (18) engages
the threads of the connecting rod (102). Using a
wrench on the nut (109), screw the connecting rod
into the displacement rod until the pin holes align.
See Fig. 8.
2. Install the pin (112*) in the hole to secure the two
rods (17 and 102) together. Make sure the pin is
flush or below the surface of the rod (17). Screw
the motor (1) onto the cylinder (101) by hand. See
Fig. 7.

intake cylinder (110) onto the pump cylinder (101).
See Fig. 5.
5. Remove the pump from the vise. Reinstall the
mounting plate (44) and secure with the retaining
ring (43).
