Graco L200CS, ti10396a, ti10392a, ti10720a Steps 14-21 apply to 500cc displacement pumps only

Repair

9.Lubricate seal (18) and install it on the bottom of cyl- inder (17). Slide intake valve housing (19) onto prim- ing piston rod (24). Ensure smooth surface of valve stop faces displacement pump intake. Screw hous- ing onto cylinder.

10.Lubricate priming piston rod (24), then slide assem- bled intake valve onto rod. Ensure packing nut (33) goes on rod first. Push valve assembly up rod, stop- ping before it reaches intake valve housing (19).

See FIG. 24.

11.Hold valve body (32) steady with a wrench while using an adjustable wrench to tighten packing nut (33); see the following table for correct torque. Use a rubber mallet on priming piston rod (24), to drive valve assembly up to stop.

Displacement
Pump	Torque
60cc and 100cc	43-47 ft-lbs (58-63 N•m)
200cc and 250cc	71-79 ft-lbs (96-107 N•m)

12.The intake seat (20) is reversible on the 200cc and 250cc displacement pumps. Inspect both sides of seat and install it with the best side facing into hous- ing (19). Push it into housing until it seats securely. Lubricate seal (21) and install in the bevel around the bottom of the seat.

For 60cc and 100cc displacement pumps, install intake seat (20) so large beveled side faces down toward pump intake.

13.Lubricate threads of intake cylinder (22). Use an adjustable wrench to screw intake cylinder into intake valve housing (19). Torque intake cylinder; see the following table for correct torque. This will also torque intake valve housing (19) and displace- ment pump cylinder (17) into outlet housing (2).

Displacement
Pump	Torque
60cc and 100cc	213-287 ft-lbs (288-387 N•m)
200cc and 250cc	345-435 ft-lbs (466-587 N•m)

Steps 14-21 apply to 500cc displacement pumps only.

14.Slide rod guide (19) onto priming piston rod (24) ensuring the end nearest valve stop goes on rod first.

15.Slide assembled intake valve onto priming piston rod (24) ensuring packing nut (33) goes on rod first. Push valve assembly up rod, stopping before it reaches rod guide (19).

16.Hold valve body (32) steady with a wrench while using an adjustable wrench to tighten packing nut (33). Torque to 71-78 ft-lbs (97-106 N•m). Use a hammer and a brass rod to carefully drive valve assembly further up rod until it reaches the stop.
