CHAPTER 6 8454
B. OPERATION
a . Function
It filters any particle or contaminated substance out of
oil.
b. Operation Principle
The filtering system as of an inlet filter installed on the
inlet gear pump is composed of filter bracket, magnet
ass'y and element ass'y. The filter used 8000 series
is by itself applicable to both hydraulic lift and direction
control of the steering wheel.
The hydraulic oil flows into IN port if the filter bracket
and the transmission oil delivered into the hydraulic
element ass'y (3) and delivery out into the outlet port
via the inner element flows into the hydraulic pump. All
foreign substances are filtered at the element this time.
In addition, a vacuum sensor and a thermo sensor are
mounted thereon to detect blockage in the filter. The
vacuum sensor and the thermo sensor are always
turned OFF under the pressure load of 500 ± 30 mmHg
and under 53°C respectively. Two switches by applica-
tion of the transistor switch are turned ON over the flow-
ing oil temperature of 53°C and over the pressure load
of 500 ± 30 mmHg with the alarm lamp on the instru-
ment panel turned on.
C. TO CHECK
As for the hydraulic filter, the oil filter shall be replaced
if its alarm lamp on the instrument panel is turned on
to avoid damages on the hydraulic system. And the
hydraulic filter also shall be replaced every service term
of 200 hours.
