Reconnecting the Displacement Pump

1.Make sure the coupling nut (10,11) and the coupling collars (12) are in place on the displacement rod. See Fig. 6.

2.Use at least two people to hold the displacement pump while another reconnects it to the frame (see the CAUTION in the removal procedure above).

3.Position and orient the displacement pump (3,4) to the frame (5) as was noted in step 6 under Disconnecting the Displacement Pump.

4.Position the displacement pump (3,4) on the tie rods

(7).

5.Screw the nuts (8) onto the tie rods (7) and torque to 81–89 N.m (60–66 ft-lb).

6.Screw the coupling nut (10) onto the rod adapter (13) 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 (18) 1/3 full with Graco Throat Seal Lubricant or compatible solvent.

8.Reconnect all hoses.

9.Replace the two guards (15) and the thumb screws

(14)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.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 11.

11.Before returning the pump to production, relieve the pressure and re-torque the packing nut (2) to 136– 149 N.m (100–110 ft-lb). The must be performed after the pump has been cycled a number of times

Disconnecting the Air Motor

1.Relieve the pressure.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 11.

2.With the bleeder type main air valve turned off, disconnect the air hose from the air motor.

3.Remove the thumb screws (14) and the two guards (15) from the sides of the proportioner.

4.Disconnect the air motor (2) from the frame (5) as follows:

CAUTION

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.

5.Note the relative position of the air motor’s air connection to the frame. The air motor must be returned to its original orientation.

6.Using an adjustable wrench (or hammer and punch), unscrew the coupling nut (9) from the rod adapter (13). Do not lose or drop the coupling collars (12). See Fig. 6.

7.Hold the tie rod flats with a wrench to keep the rods from turning. Unscrew the nuts (8) from the tie rods

(6). Carefully remove the air motor (2) from the frame.

8.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.

Reconnecting the Air Motor

1.If the connecting rod has been removed from the Air Motor Stud as a part of servicing, be sure to use thread adhesive when reinstalling the connecting rod on to the Air Motor Stud.

2.Make sure the coupling nut (9) and the coupling collars (12) are in place on the rod adapter (13).

3.Use an overhead hoist to position the air motor on the frame in the same orientation as noted in step 5 of disconnecting the air motor. (see the CAUTION in the removal procedure above).

4.Position the air motor (2) on the tie rods (6).

5.Screw the nuts (8) onto the tie rods (6) and torque to 81–89 N.m (60–66 ft-lb).

6.Screw the coupling nut (9) onto the rod adapter (13) 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.Reconnect the air hose

8.Replace the two guards (15) and the thumb screws (14) onto the sides of the proportioner.

9.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
