1.
Make sure the coupling nuts (K, L) and
the coupling collars (M) are in place on the
displacement rod. See Fig 3, page 15.
2.
Use at least two people to hold the displacement
pump while another reconnects it to the frame.
3.
Position and orient the displacement pump (C,
D) to the frame (E) as was noted in step 7 under
Disconnect the Displacement Pump, page 19
4.
Position the displacement pump (C, D) on the
tie rods (G).
5.
Screw the nuts (H) onto the tie rods (G) and
torque to 81–89 N.m (60–66 ft-lb).
6.
Screw the coupling nut (K,L) onto the rod adapter
(N) loosely. Hold the rod adapter flats with a
wrench to keep it from turning. Use an adjustable
wrench to tighten the coupling nut. Torque to
196–210 N.m ft-lb).
7.
Fill the wet cup (U) 1/3 full with Graco Throat
Seal Lubricant or compatible solvent.
8.
Reconnect all hoses.
9.
Replace the two guards (R) and the thumb
screws (P) from the sides of the proportioner.
10. Turn on the air supply. Follow the procedure for
starting the pump on page 11. Run the pump
slowly at first to ensure proper operation.
11. Before returning the pump to production, relieve
the pressure and re-torque the packing nut (B)
to 136–149 N.m (100–110 ft-lb). The must be
performed after the pump has been cycled a
number of times

Be sure to use an overhead hoist when lifting,
moving or disconnecting the air motor. This air
motor weighs 145 lbs. and is too heavy for one
person to handle. A lift ring is provided on the
motor for this purpose.
4.
Note the relative position of the air motor’s air
connection to the frame (E). The air motor (B)
must be returned to its original orientation.
5.
Using an adjustable wrench (or hammer and
punch), unscrew the coupling nut (J) from the rod
adapter (N). Do not lose or drop the coupling
collars (M). See Fig. 6.
6.
Hold the tie rod flats with a wrench to keep the
rods from turning. Unscrew the nuts (H) from the
tie rods (F). Carefully remove the air motor (B)
from the frame.
7.
Refer to the separate manual supplied for air
motor service. Be sure to look at the model
number stamped on the air motor and use the
appropriate manual for service and reference.
