Step 8: Install PTO and pump.
• Before installing the pump to the PTO, always check the direction of the PTO output shaft
to determine which direction the hydraulic pump needs to rotate to operate the equip-
ment. If this is not determined prior to installing the hydraulic pump, the hydraulic pump
may rotate in the incorrect direction and damage the front shaft seal.
PTO Direction of Rotation Tip:
Viewed by standing at the rear of the vehicle, looking forward at the PTO shaft, with the
PTO shaft pointing toward the rear of the vehicle:
Remember that the PTO is specified by looking from the rear of the truck to the front of the
truck. The driven equipment (pump) is specified by looking from the front of the truck to
the rear of the truck.
• Use the brand specific PTO/Pump installation instructions. If the directions are not quite
clear, contact Stellar

Customer Service or consult with a hydraulic specialty house or
company prior to installation.
