Reassemble the Coupling Rod and Tie Rods to the Motor

Use this procedure only if the coupling rod (F) and tie rods (C) have been disassembled from the motor, to ensure proper alignment of the motor shaft to the piston rod.

1.Loosen, but do not remove, the screws holding the adapter plate (J) to the motor (E), on Viscount I Plus pumps. See FIG. 6. For Viscount II pumps, torque screw (N) to 50-55 ft-lb (68-75 N•m) into motor (E).

2.Screw the tie rods (C) into the adapter plate (J) and torque to 50-55 ft-lb (68-75 N•m). On Viscount I Plus pumps, the tie rods will engage threaded holes in the base of the motor. Viscount II pumps will engage into the adapter plate (J).

3.Fill the cavity in the bottom of the motor shaft with grease. Screw the coupling rod (F) into the motor shaft until the pin holes align. Install the pin (A) in the first hole from the end of the coupling. On Vis- count II pumps, torque the coupling nut (M) into the motor shaft.

4.Align the lower (D) with the tie rods (C) and loosely install the tie rod locknuts (B).

5.Insert the collars (G) and screw the coupling nut (K) onto the coupling rod (F) and torque to 90-100 ft-lb (122-135 N•m).

6.For Viscount I Plus pumps, torque the holding the adapter plate (J) to the motor (E) to 15-17 ft-lb

(20-23 N•m). For Viscount I Plus and Viscount II pumps, torque the tie rod locknuts (B) to 50-55 ft-lb (68-75 N•m).
