6. Insert the displacement rod (7) into the top of the

cylinder (11), being careful not to scratch the cylin-
der. Insert only until the packings are in the cylinder.

7. Lubricate the o-ring and apply thread lubricant to the

cylinder, then reinstall the cylinder in the outlet
housing (16).

8. Install the ball (2), guide (22), o-ring 12), and ball

stop pin (5) in the intake valve housing (13). Place
the intake valve assembly in the cylinder (11). Apply
thread lubricant to the locking ring and cylinder (11),
and screw the ring onto the cylinder.

9. Reconnect the displacement pump to the reciproca-

tor by performing the reverse of the disassembly
procedure on page 12. (F
