Graco P39LCS Manual De Usuario

1. If the air motor was removed, refer to the Supply 

Units Repair-Parts manual for installation instruc-

tions.

2. Use caution when reconnecting displacement 

pump. Place displacement pump (2) on tie rods (3).

3. Screw nuts (5) onto tie rods (3) and torque to 50-60 

ft-lb (68-81 N•m).

4. Pumps with 100cc, 200cc, and 250cc displacement 

pumps only: Install coupling (7), and slide coupling 

cover (8) down. Install clip (9).

5. Pumps with 60cc and 500cc displacement pumps 

only: Reinstall coupling nut and coupling covers on 

displacement rod. Slide coupling nut up and tighten 

using a torque wrench with a claw foot; see the fol-

lowing table for torque values.

6. Reconnect all hoses. Reconnect ground wire and 

reed switch cable (units with remote DataTrak) if 

they were disconnected. Fill wet cup (R) 1/3 full of 

Graco Throat Seal Liquid or a compatible solvent. 

7. Attach platen to displacement pump. Refer to the 

Supply Units Repair-Parts manual for instructions

8. Turn on the air power supply. Run the pump slowly 

to ensure that it is operating properly.

9. Allow 2 hours for the thread sealant to cure before 

returning the pump to service.

Be sure to use at least two people when lifting, mov-

ing, or connecting the pump. This pump is too heavy 

for one person. If you are connecting the displace-

ment pump to a motor that is still mounted (for exam-

ple, on a ram), be sure to support the displacement 

pump while it is being connected, to prevent it from 

falling and causing injury or property damage. Do this 

by securely bracing the displacement pump, or by 

having at least two people hold it while another con-

nects it.

On Premier models, ensure that the rod adapter (6) 

has not loosened during maintenance. Proper 

torque is necessary to prevent the rod adapter from 

loosening during the pump operation.

If the rod adapter (6) has loosened during mainte-

nance, remove the adapter and apply Loctite 2760 

(or equivalent) to the rod adapter and air motor pis-

ton threads, and then torque to 230-250 ft-lbs 

(312-340
