(18)from the intake valve housing (21).

4.Unscrew the cylinder (15) from the outlet housing (5), note its orientation and carefully pull the cylin- der off the pump. Remove the o-ring (6) from the outlet housing.

NOTE: It is important to replace the cylinder in the same orientation as both ends are NOT alike. Failure to install correctly may result in failure of pump or premature seal wear. For instructions on how to verify correct orientation, see NOTE in step 7 on page 16.

5.Loosen the packing nut (14), then pull the dis- placement rod (1) and connecting rod (8) out the bottom of the outlet housing (5).

6.Secure the flats of the displacement rod (1) in a vise. Unscrew the coupling nut (7) from the dis- placement rod. Remove the connecting rod (8) and attached parts.

7.Place the flats of the piston mounting stud (13) in a vise. Loosen the jam nut (9) and unscrew the adapter (10) from the piston mounting stud (13). Set the connecting rod (8) aside. Remove one cotter pin (12) and the ball stop pin (11), taking not which set of holes it is in. Then remove the ball (16).

8.Unscrew the piston stud (27) from the piston mounting stud (13). Remove the piston packings (29, 30), glands (28, 31) , shims (35), and washer (26).

10.Inspect all parts for damage. Clean all parts and threads with a compatible solvent before reassem- bling. Inspect the polished outer surface of the displacement rod (1) and inner surface of the cylinder (15) for scratches, scoring, or other dam- age, which can cause premature packing wear and leaking. To check, run a finger over the surface or hold the part up to the light at an angle. Be sure the ball seats of the piston (27) and intake valve housing (21) are not chipped or nicked. Replace any worn or damaged parts.
