PTO gear oil viscosity and adjustment of tempera-
ture switch units
If the new gear oil has a different viscosity grade compared with
the drained oil it is necessary to adjust the temperature limit val-
ues at switch units (K43 and K182), illustration Z24089 in accor-
dance with the viscosity grade of the new gear oil. The switch
units are located in the X2 switch box in the cab base.
Legend for illustration Z24089
K43 - Switch unit for gear oil temperature warning message
"PTO oil Temperature too high".
K182 - Switch unit for pre-load of gear oil cooler circuit
Adjust switch units to the respective oil viscosity grade as
follows:
Oil viscosity grade according to ISO
-K43- Adjust temperature limit value to
switching point °C
-K182- Adjust temperature limit value
to switching point °C
Adjustment procedure for (K43 and K182):
Adjust the temperature limit value at the cogwheel next to the
drum scale on switch unit front cover.
NOTICE
Turn the cogwheel sensitively. DO NOT turn beyond the
STOP marking, otherwise the internal potentiometer driver
pin will disengage resulting in wrong value transmission.
Refer to Service Bulletin No. AH02508b for functional test of
the switch unit.
