Cylinder Control Valve Installation
Cylinder Hydraulic Control Circuit: (continued)
6.Hydraulic Cylinder Hoses. The Hoses for the Hydraulic Cylinders will be marked with bands that have the Part Numbers on them. These part numbers will vary with the size of the Boom Model. The 28 ft. model will have more hoses for the Boom Extend Function, the model with the Hydraulic Door on cutter head willhave more hoses. To find which Hose you have you will need to consult the Parts / Operators manual. When connecting the Hoses to The Valve use these numbers to connect the correct hoses to the correct ports. It may be required that you do some tracing of hoses to find which hose is hooked to which end of a Cylinder. Listed below is a list of which end of Hydraulic Cylinder should be connected to which Port on valve. (See Figure 2 & 3)
MECHANICAL VALVE MODELS
Cylinder | Rod End / Port | Base End / Port | |
Tilt | ("B") | ("A") | Standard |
Extend / Door ("B") | ("A") | Only used with 28' Model or Optional Cutter Door) | |
Dipper | ("B") | ("A") | Standard |
Lift | ("A") | ("B") | Standard |
Swing | ("A") | ("B") | Standard |
You must consult the Parts Manual to determine correct Hoses used on the Model you have. Also the type Head used will make the Hose vary. There is a Electrical control valve Option, this will make a difference of which hose is connected where. If the hoses are connected to the wrong side of valve it should not damage any thing, it will mean that the control lever function will be reversed or may not work at all because the Relief Valve is in the wrong direction of Oil Flow to operate.. Changing the Hoses on the hose ports of the valve will change this.
REMOTE CABLE OPERATION AND INSTALLATION:
1.Remote operation of the boom movement control valve can be achieved with the use of cables and remote actuator handles. The remote operation system is standard equipment on cab tractor units and can be installed on ROPS tractors as well (See Figure 4). Four cable lengths are available and should be ordered based on the length required to reach from the valve to the Operator’s location with out binding or kinking. Cable lengths are limited to 48,60,72 and 102 inches.
2.To install the cables to the valve, each valve section will require a cable installation kit (4 kits for a
