MAINTENANCE
Hydraulic System.
Manifolds and Valve Stacks.
Main Motor manifold.
The Main Motor Manifold ’ A ’, is located on the right
side of the tractor between the Conveyor and the
Tractor.
The Motor Manifold receives approximately 15 gallons
per minute from the ‘center’ section of the Hydraulic
Pump. The flow is then directed through Solenoid
Valves in the manifold, to the:
•
Cutter Head Motor.
•
Main Conveyor Motor.
•
Roll-up Conveyor Motor.
•
Index Conveyor Motor.
Relief pressure in the manifold is set at the factory at
2650 psi.
Index Conveyor Flow Control Orifice.
If the Index Conveyor movement slows noticeably the
fault may be with the Flow Control Orifice located
under the Index Conveyor Spool.
To install a new Orifice:
•
Remove the Nut ‘ B ’, and the Coil ‘ C ’.
•
Use a Hex Socket to carefully unscrew the
Valve/Spool Assembly from the Manifold.
•
Use a magnet to ‘reach in’ and remove the
faulty Orifice from the Manifold.
•
Install the new Orifice.
•
Check that the O-Ring under the head of the
Valve/Spool Assembly is not damaged,
replace if necessary.
•
Screw the Valve /Spool Assembly into the
Manifold.
•
Refit the Coil ‘ C ’, and Nut ‘ B ’. Tighten the Nut
to 12 ft.lbs. Do not over-tighten the Nut as it
may result in damage to the Coil.
Gripper Head/Pallet Lift Forks Manifold.
The Gripper Head/Pallet Lift Forks Manifold ‘ D ’ is
located in front of the right side Pallet Forks Lift
Cylinder. It receives approximately 7 gallons per
minute
from the front section of the Hydraulic Pump. The flow
is then directed, through solenoid operated valves in
the manifold to the:
•
Gripper Head Fingers.
•
Gripper ‘Squeeze’ Function.
•
Pallet Lift Forks Cylinders.
Relief pressure in the manifold is set at the factory at
1500 psi.
A check valve limits the pressure to the Gripper fingers
to 900 psi.
