CONTROL VALVE OPERATION FORWARD, SECOND GEAR WITH 4WD ENGAGED
Pressure oil from the system regulating valve flows to the pressure reducing valve.
The pressure lowers to 5.5 bar. This oil flows to the 6 solenoids.
Oil also supplies the modulation valve.
When the powershift lever is moved forward and twisted anti clock wise a electrical signal is sent to:
Z
Oil flows from the system pressure regulating valve at 20 bar through the 4WD spool to engage the 4WD
clutch.
Z
System pressure also flows through the range modulation valve, then through the 1st 2nd spool to engage
the 2nd gear clutch.
Z
The high low solenoid which energizes allowing pilot oil to flow to the shift spool. This will allow oil to flow to
the low clutch.
Z
The neutral forward solenoid which energizes allows pilot pressure to flow to the shift spool this will allow oil
to flow on to the forward low shift spool.
Z
The modulation valve has a reducing current from the microprocessor, pilot pressure gradually increases act-
ing on the boost valve and it multiplies pilot pressure.
Z
The oil from the boost valve is modulated allowing a steady increase of pressure to act on the forward low
clutch pack which gradually takes up drive until clutch pressure reaches 20 bar.
