PTO62 & PTO72
Procedure
Before starting, clear the area of any bystanders, especially
small children.
Step 1
• On the workbench, attach the 1/2" elbow connector to the
filter head (pre-installed on PTO72).
• Attach the 3/4" barbed hose fitting to the tank.
• Tighten connections as specified in Hydraulic Fitting Torque
on page 13.
• Slip the gear clamps over the suction hose. Attach one
end to the tank and to the other end to the input of the PTO
pump. Tighten the gear clamps.

Step 2
Prepare to install the reservoir tank by making sure the backhoe
frame is clear and the hydraulic hoses are moved out of the way.
• Move the tank into position.
• Install bolts through rectangular holes in the foot rest into
the tank mounting holes.
• Adjust the tank position as required then tighten mounting
bolts.

Step 3
Connect the pressure line and return lines. The pressure line
is connected to the pump pressure port. The return line is
connected to the return connection on the reservoir. (Refer to
the illustration on the next page.)
Apply thread sealant to the hose threads to prevent leaks.
Tighten connections as specified in the Hydraulic Fitting Torque
on page 13.
If unsure, the hoses are connected to the control
valve on the backhoe as follows:
• The pressure line on the backhoe is connected
to the right-hand side of the control valve at the
P port (marked on the valve body).
• The return line is connected at the left-hand side
of the valve at the
T port.

The backhoe directional control valve does not allow reverse
flow if lines are connected incorrectly.
