  7. INTRODUCTION Foreword IMPORTANT INFORMATION All repair and maintenance works listed in this manual must be carried out only by staff belonging to the NEW HOL- LAND Service network, strictly complying with the instructions given and using, whenever required, the special tools. Anyone who carries out the above operations without complying with the prescriptions shall be responsible for the subsequent damages. The manufacturer and all the organizations of its distribution chain, including - without limitation - national, regional or local dealers, reject any responsibility for damages due to the anomalous behavior of parts and/or components not approved by the manufacturer himself, including those used for the servicing or repair of the product manufactured or marketed by the Manufacturer. In any case, no warranty is given or attributed on the product manufactured or marketed by the Manufacturer in case of damages due to an anomalous behavior of parts and/or components not approved by the Manufacturer. No reproduction, though partial of text and illustrations allowed. 84477609A 27/09/2011 3
  8. INTRODUCTION Foreword Technical Information This manual has been produced by a new technical information system. This new system is designed to deliver technical information electronically through Web delivery, DVD and in paper manuals. A coding system called ICE has been developed to link the technical information to other Product Support functions e.g. Warranty. Technical information is written to support the maintenance and service of the functions or systems on a customers machine. When a customer has a concern on his machine it is usually because a function or system on his machine is not working at all, is not working efficiently, or is not responding correctly to his commands. When you refer to the technical information in this manual to resolve that customers concern, you will find all the information classified using the new ICE coding, according to the functions or systems on that machine. Once you have located the technical information for that function or system then you will find all the mechanical, electrical or hydraulic devices, compo- nents, assemblies and sub assemblies for that function or system. You will also find all the types of information that have been written for that function or system, the technical data (specifications), the functional data (how it works), the diagnostic data (fault codes and troubleshooting) and the service data (remove, install adjust, etc.). By integrating this new ICE coding into technical information , you will be able to search and retrieve just the right piece of technical information you need to resolve that customers concern on his machine. This is made possible by attaching 3 categories to each piece of technical information during the authoring process. The first category is the Location, the second category is the Information Type and the third category is the Product: • LOCATION - is the component or function on the machine, that the piece of technical information is going to describe e.g. Fuel tank. • INFORMATION TYPE - is the piece of technical information that has been written for a particular component or function on the machine e.g. Capacity would be a type of Technical Data that would describe the amount of fuel held by the Fuel tank. • PRODUCT - is the model that the piece of technical information is written for. Every piece of technical information will have those 3 categories attached to it. You will be able to use any combination of those categories to find the right piece of technical information you need to resolve that customers concern on his machine. That information could be: • the description of how to remove the cylinder head • a table of specifications for a hydraulic pump • a fault code • a troubleshooting table • a special tool 84477609A 27/09/2011 4
  9. INTRODUCTION How to Use this Manual This manual is divided into Sections. Each Section is then divided into Chapters. Contents pages are included at the beginning of the manual, then inside every Section and inside every Chapter. An alphabetical Index is included at the end of a Chapter. Page number references are included for every piece of technical information listed in the Chapter Contents or Chapter Index. Each Chapter is divided into four Information types: • Technical Data (specifications) for all the mechanical, electrical or hydraulic devices, components and, assem- blies. • Functional Data (how it works) for all the mechanical, electrical or hydraulic devices, components and assem- blies. • Diagnostic Data (fault codes, electrical and hydraulic troubleshooting) for all the mechanical, electrical or hy- draulic devices, components and assemblies. • Service data (remove disassembly, assemble, install) for all the mechanical, electrical or hydraulic devices, components and assemblies. Sections Sections are grouped according to the main functions or a systems on the machine. Each Section is identified by a letter A, B, C etc. The amount of Sections included in the manual will depend on the type and function of the machine that the manual is written for. Each Section has a Contents page listed in alphabetic/numeric order. This table illustrates which Sections could be included in a manual for a particular product.

Pressure Relief Valve NOTE: Semi Powershift transmission tractors have two shift buttons plus an extra range button on the reverse side of the handle. CLOSED CENTRE LOAD SENSING HIGH PRESSURE HYDRAULIC CIRCUIT The principal of operation of the closed centre load sensing high pressure hydraulic circuit with variable flow piston pump is to supply oil flow on demand. It also enables simultaneous operation of the trailer brakes, hydraulic lift, remote control valve assemblies and front axle suspension where fitted. The load sensing variable flow piston pump offers significant benefits in reducing the engine power loss that occurs in open centre systems where a high volume of oil, often far in excess of demand, is continuously pumped round the hydraulic circuit even when they are not being operated. A fixed displacement pump (Charge Pump) serves as an initial displacement pump for the variable displacement pump . The variable displacement pump first of all supplies oil to the trailer brake valve (where fitted), the remote valves and electronic draft control valve and a pilot oil supply with lower priority. The highest load pressure is indicated to the flow and compensating valve on the pump via the load sensing line. The flow and compensator valve controls the pump pressure in such a way that it always exceeds the highest load pressure by a pre-set difference. A priority valve for low pressure circuit demand is located in the bottom subplate of the remote valve stack. Tractors fitted with Electro-hydraulic remote valves also have high pressure oil supplied from the variable displacement pump to the top plate of the remote valve stack. The oil passes through the top plate via a small filter and a pressure limiting valve ( 20 - 22 Bar). The oil is then directed to the pilot oil supply of the electro-hydraulic control valve. 84477609A 27/09/2011 A.10.A / 10

  26. HYDRAULIC, PNEUMATIC, ELECTRICAL, ELECTRONIC SYSTEMS - PRIMARY HYDRAULIC POWER SYSTEM BAIL07APH326ASA 21 Operation of the closed centre high pressure hydraulic circuit is as follows:- The components in the high pressure hydraulic circuit are connected by their load sensing lines to the hydraulic load sensing valve which controls the output of the hydraulic pump. When the trailer brakes, remote control valves, hydraulic lift or front axle suspension (where fitted) are operating, the load sensing valve on variable flow piston pump, compares the pressure in the component load sense line with the output pressure of the hydraulic pump. If pump output pressure is less than the combined pressure of the load sense line and spring force of the flow con- trol valve, then pump output continues to increase. When circuit demand is satisfied pump pressure overcomes the combined pressure of the load sense line and flow compensating valve spring. This moves the spool in the flow com- pensating valve to the right, allowing control pressure oil to be directed to the variable flow swash plate servo piston, which de-strokes the pump to adjust output to circuit demand. High Pressure oil is fed to a subplate at the bottom of the remote valve stack where it is directed to the Trailer Brake valve which has priority for safety reasons. The oil is then redirected to the Electronic Draft Control Valve and the Electro-Hydraulic Remote Valves. Within the subplate is a pressure compensating valve which diverts the oil to the low pressure system at a pressure of 18 bar (261.00 psi). High Pressure oil is also fed to the top of the Remote Valve stack through an end plate which incorporates a pressure limiting valve and this supplies oil at 20 - 22 bar to the pilot line galleries in the Electro-Hydraulic Remote Valves. Surplus oil from the charge pump to the variable displacement pump is fed past the 0.8 bar valve and boosts the pressure in the lubrication circuit. The trailer brake valve is located on the sub plate of the remote valve stack. The valve diverts oil pressure to the trailer brakes whenever the brake pedals are depressed. The trailer brake has absolute priority over other services in the circuit. BAIL07APH327ASA 22 The remote valves are available as two, three or four valves per tractor. The valves can be double-acting with float and kick out. Double acting convertible to single-acting with float. 84477609A 27/09/2011 A.10.A / 15

BSE3664A_442 23 BAIL07APH328ASA 24 When the oil is cold and pressure differential across the oil cooler is higher than 6 bar ( 87 lbf/in2) the cooler by-pass valve (1) located in the transmission top cover will operate to ensure that adequate flow to the lubrication circuit is maintained. This feature of diverting oil from the cooler assists in aiding a rapid warm up of oil in cold weather con- ditions. The steering pump / steering return oil is directed through the oil cooler at the front of the tractor and is limited to a maximum pressure of 5.59 bar (81.06 psi)) by the lubrication relief valve located in the transmission top cover. 84477609A 27/09/2011 A.10.A / 16
