DESCRIPTION
Numbers and letters in parentheses refer to Fig. 1.
The single spool body control valve, which is fitted with
electro hydraulic operation, is mounted off the cradle
assembly at the rear of the cab. The main components
of the control valve assembly are a four position
control spool (1), relief valve (37), check valve
assembly and valve housing (41).
The position of the control spool is controlled by the
body control joystick by means of electrical signals to
the pressure reducing valves (13). Refer to
Section 230-0060, BODY CONTROL JOYSTICK. The
body control joystick has a pre-feel ramp which
controls the current to the pressure reducing valve
