Foreword T echnical Information
This manual has been produced a new technical information This new system designed deliver technical information electronically through - ROM and paper manuals. A coding system called ICE has been developed link the technical information other Product Support functions W arranty
T echnical information written support the maintenance and service the functions systems a customers When a customer has a concern his machine usually because a function system his machine not working not working ficiently , not responding correctly his When you refer the technical information this manual resolve that customers you will find all the information classified using the new ICE according the functions systems that Once you have located the technical information for that function system then you will find all the mechanical, electrical hydraulic devices, assemblies and sub assemblies for that function Y will also find all the types information that have been written for that function the technical data the functional data (how the diagnostic data (fault codes and troubleshooting) and the service data (remove, install adjust, etc.). integrating this new ICE coding into technical information , you will able search and retrieve just the right piece technical information you need resolve that customers concern his machine. This made possible attaching 3 categories each piece technical information during the authoring
The first category the Location, the second category the Information T ype and the third category the Product:
• LOCA TION - the component function the that the piece technical information going describe Fuel
• INFORMA TION TYPE - the piece technical information that has been written for a particular component function the machine Capacity would a type T echnical Data that would describe the amount fuel held the Fuel tank.
• PRODUCT - the model that the piece technical information written for
Every piece technical information will have those 3 categories attached Y will able use any combination those categories find the right piece technical information you need resolve that customers concern his
That information could be:
• the description how remove the cylinder head
• a table specifications for a hydraulic pump
• a fault code
• a troubleshooting table
• a special tool 87727160B

Operation the closed centre high pressure hydraulic circuit follows:The components the high pressure hydraulic circuit are connected their load sensing lines the hydraulic load sensing valve which controls the output the hydraulic
When the trailer brakes, remote control valves, hydraulic lift front axle suspension (where fitted) are operating, the load sensing valve variable flow piston compares the pressure the component load sense line with the output pressure the hydraulic pump output pressure less than the combined pressure the load sense line and spring force the flow trol then pump output continues When circuit demand satisfied pump pressure overcomes the combined pressure the load sense line and flow compensating valve spring. This moves the spool the flow pensating valve the allowing control pressure oil directed the variable flow swash plate servo which - strokes the pump adjust output circuit
