Technical Information
This manual has been produced by a new technical information system. This new system is designed to deliver
technical information electronically through CDROM 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 customer’s
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 customer’s 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 customer’s 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 for which the piece of technical information is written.
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 customer’s 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

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, assemblies.
• Functional Data (how it works) for all the mechanical, electrical or hydraulic devices, components and assemblies.
• Diagnostic Data (fault codes, electrical and hydraulic troubleshooting) for all the mechanical, electrical or hydraulic
devices, components and assemblies.
• Service data (remove disassembly, assemble, install) for all the mechanical, electrical or hydraulic devices, com-
ponents 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.

The feeder valve (1), is located on the left side of the feeder housing, and is used to provide hydraulic control of all
header functions. The feeder valve supports the reel drive valve (2), which is mounted on the inside of the feeder
valve, and includes the reel raise/lower and reel fore/aft valves as standard. If the combine is equipped with header
lateral tilt, then that valve is also included in the feeder stack.

LOW PRESSURE STANDBY
When there is no demand for oil flow, the pump will go into the low-pressure standby mode. Low-pressure standby
means low pressure and minimal flow in the system. When the engine is not running, no pressure exists in any circuit.
In this state, the swash plate control spring is holding the piston pump at full stroke. When the engine is started and
the pump begins to rotate, it will momentarily try to pump oil. This creates outlet pressure at the pump. This pressure
is directed to the flow compensator spool (5) and the high-pressure compensator spool (6) through passages in the
piston pump back plate. The two spools in the pump compensator are both spring biased. The flow compensator
spool has a 28 bar (400 psi) spring , while the high-pressure compensator spool has a 210 bar (3050 psi) spring.
The pump pressure is directed to the non-spring side of these two spools. As pressure builds, it will cause the flow
compensator spool (5) to shift against its spring. When the spool shifts, it allows pump oil to pass (7) to the pump
control piston. This piston will extend and cause the swash plate to move against the control spring. The swash plate
will move to a nearly zero degree angle, de-stroking the pump. In this condition, the pump will only move enough oil
to make up for internal leakage within the system and maintain 29 - 38 bar (425 - 550 psi). The pump will remain
in this position until there is a demand for oil. In low-pressure standby mode the pump produces less heat and uses
less horsepower than an open-center system. Low pressure standby also makes starting the engine easier.
Minimum system pressure is 29 - 38 bar (425 - 550 psi) in the low-pressure standby mode. There is a 0.61 mm
(0.024 in) dynamic sensor orifice located in the steering priority spool. The dynamic sensor orifice connects the pump
outlet port to the signal port of the pump compensator through the orifice check valve. If the oil in the signal line can
flow through the steering hand pump too freely a 0.78 mm (0.031 in) orifice in the steering hand pump signal passage

provides back pressure in the signal line. This signal pressure of 3.45 - 10.3 bar (50 - 150 psi) is sent to the spring
end of the flow compensator spool through the sense line (4). The spring pressure of 28 bar (400 psi) plus the signal
line back pressure puts the pump into low pressure standby mode ranging from 29 - 38 bar (425 - 550 psi).

PRESSURE AND FLOW COMPENSATION
The flow of oil from the pump is controlled by the difference in pressure at opposite ends of the flow compensator
spool (5). When a valve is opened to operate a function on the combine, the outlet pressure of the pump will drop.
This drop in pressure is detected on the non-spring end of the flow compensator spool (5). The spring will now shift
the spool and allow oil to drain from the pump control piston into the pump case. The swash plate control spring will tilt
the swash plate, causing the pump to provide more oil flow. When the flow demand of the system is met, the swash
plate will be tilted to provide only the flow required by the component(s) in use. The working pressure in the system is
fed back to the spring-end of the flow compensator spool (5) through the sense line. (4). When the outlet pressure is
high enough to overcome both the spring and work pressure in the sense line, the flow compensator spool will shift,
allowing oil to flow to the control piston at (7), causing the pump to de-stroke to match the demand.
