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 first 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.
