STARTER SYSTEM TROUBLESHOOTING:
Before continuing with starter system troubleshooting make sure the starting system checklist has been followed. Also, confirm starting system power distribution is good
.Key switch OFF, there must be B+ power at:
– Starter solenoid B+ stud (on starter motor assembly)
– Starter relay B+ stud
– Ignition switch terminal #1
STEERING RELIEF VALVE

• If the steering wheels are turned to their stops, or the wheels can no longer be turned, the steering system pressure increases until it goes on relief. When the steering relief opens it will limit the amount of pressure that may be exerted on the spring end of the steering priority spool (6). This will let the PFC high-pressure standby force the spool against the spring, diverting excess pump flow to the hydraulic circuits. When the signal pressure increases above 185 bar (2680 psi), a simple relief valve (7) located in the main valve block signal line will open.
• An office (10) (in the hand pump) is located in the circuit to limit the amount of oil that is being fed into the signal line, so that the relief valve can limit the pressure in the signal line. This will limit the signal pressure available to the steering priority valve and the compensator. The purpose of this relief valve is to limit the maximum pressure available to the spring-side of the priority spool, thus allowing oil to flow to the main valve assembly. If the steering relief pressure is set too close to the high-pressure stand-by pressure, the oil flow to the main valve assembly may be cut off when the steering relief valve opens.

MANUAL STEERING

• The steering circuit will permit manual steering control of the combine in the event of a dead engine; however, steering effort is more demanding. Manual steering uses the existing oil in the steering circuit for the oil supply, and the operator turning the steering wheel as input power. In manual steering operation, the metering section (turned by the operator) is used as the pump to supply oil to the steering cylinder. As the operator rotates the steering wheel, the centering springs compress and the main spool changes relationship to the sleeve.
• Since there is no supply of hydraulic oil from the PFC pump, the inlet check valve will be held on its seat by the spring. At this point, the recirculation check ball will not be seated due to the fact there is no incoming oil. This allows oil from the return port to be drawn past the recirculation check, through the main spool and sleeve, to supply the metering section, which is now acting as the pump. The metering section controls the amount of oil being directed to the cylinder based on the rotation speed of the steering wheel. Oil flow from the metering section is then directed to the spool and sleeve, then out to the steering cylinder.
