Reassembling the Coupling Rod and Tie
Rods (President and Viscount only)
NOTE: Use this procedure only if the coupling rod (G)
and tie rods (C) have been disassembled from a
President or Viscount motor, to ensure proper align-
ment of the motor shaft to the piston rod.
1. Loosen, but do not remove, the screws (M) holding
the adapter plate (L) to the motor (E). See Fig. 10.
2. Screw the tie rods (C) into the adapter plate (L)
and torque to 68–75 NSm (50–55 ft-lb).
On Viscount I+ pumps, the tie rods will engage
threaded holes in the base of the motor.
3. Fill the cavity in the bottom of the motor shaft with
grease. Screw the coupling (G) into the motor
shaft until the pin holes align. Install the pin (F) in
the second hole from the end of the coupling for
President pumps, and in the first hole from the
end of the coupling for Viscount pumps.
4. Align the displacement pump with the tie rods (C)
and loosely install the locknuts (B).
5. Screw the coupling nut (K) onto the piston rod (H)
and torque to 102–109 NSm (75–80 ft-lb).
6. Torque the screws (M) holding the adapter plate
(L) to the motor (E) to 20–23 NSm (15–17 ft-lb).
Torque the tie rod locknuts (B) to 68–75 NSm
(50–55 ft-lb).
