ATTACHING HYDRAULIC MOTOR TO PUMPTUBE
1. Tightly Attach Tie Rods (Item 38) to the Mounting Plate (Item 37).
(Use short threaded end of tie rods).
2. Mount hydraulic motor on top of pumptube outlet body and tightly
connect pumptube coupling nut to Piston Rod (Item 29).
3. Hand tighten tie rods to the pumptube with four Nuts (Item 39)
supplied with hydraulic motor.
4. Connect hydraulic supply and return lines and slowly cycle pump
several times, using only enough pressure to operate the pump
without stalling
NOTE: Air in the hydraulic motor may cause slow or erratic shifting during the rst few cycles after connecting the hydraulic lines.
5. Stop the pump on an "up" stroke and tighten the four nuts to
securely fasten the hydraulic motor to the pumptube.
