17. Place cylinder (17) sideways in a vise with soft jaws.
18. Lubricate seal (18) and place it on bottom of cylin-
der (17). (Cylinder is symmetrical so either end can
be the bottom.)
19. Slide displacement rod (1), piston assembly (T),
intake valve assembly (R), and priming piston rod
(24) into cylinder (17) from bottom until mating sur-
faces of rod guide (19) and cylinder (17) meet.
20. Put intake housing (22) upright in a vise, making
sure it is off-center so there is a sufficient clearance
for priming piston rod (24) to be lowered through
housing. Insert intake seat (20) into intake housing
(22) so the flat seat is facing up. Lubricate seal (18)
and place it on top of intake seat (20). Lower rod
and cylinder assembly into intake housing until rod
guide (19) bottoms on intake seat (20) and priming
piston rod (24) protrudes from bottom of intake
housing (22).
21. Lubricate seal (18) and place it on top of cylinder
(17). Insert outlet housing (2) on to cylinder. Install
six long capscrews (45) through outlet housing (2)
and into intake housing (22). Using a socket wrench,
torque screws oppositely and evenly to 180-195
ft-lbs (244-264 N•m).
22. Lubricate throat packings (M), and install them in
throat cartridge (3) one at a time with the lips of the
v-packings or u-cup facing down. Refer to Packing
Kit sections for each displacement pump size for the
correct throat packing configuration for your dis-
placement pump.
