CONTROL VALVE, SAFETY VALVE, AND
INCHING VALVE
The
Control Valve
is mounted on the inner side of the
transmission case cover (see Figure 10). The control
valve includes three components: controlling slide
valve, constant pressure valve, and adjusting valve.
•
Controlling Slide Valve
: Used to control
forward and backward functions.
•
Constant Pressure Valve
: Maintains the oil
pressure of the hydraulic clutch to be within the
range of 1.1-1.4 MPa (159.5-203.1 psi).
•
Adjusting Valve
: It is located between inching
valve and controlling slide valve. When
controlling slide valve is fully open, this valve
will start adjusting to reduce the impact of clutch
during engagement.
The
Overflow Valve
: The overflow valve is connected
to the transmission case and allows the oil pressure
from the torque converter to maintain within its
operating range 0.5-0.7 MPa (72.5-101.5 psi). See
Figure 16
The
Inching Valve
The inching valve is installed on
the left side of transmission case. The spool is
connected to the linking rod of the inching pedal. This
spool will move forward when inching pedal is
pressed. The oil pressure of the hydraulic clutch will be
reduced, causing the truck to move slowly. See
Figure 11.
