5. OIL FILTER

5.1 STRUCTURE OF OIL FILTER

A. Function
• Filters particle or sludge from oil.
B. Operation
• Oil filter consists of filter bracket, magnet assembly
and element assembly as intake filter installed at
intake side of gear pump.
• Filter used in M24 series is a hydraulic elevating
and steering filter.
• Hydraulic filter, installed at the intake side of gear
pump, is installed with a permanent magnet in the
middle of elements, and attached with a vacuum
sensor and temperature sensor to sense blockage.

5.2 FUNCTION AND OPERATION

• Hydraulic oil enters the IN port of filter bracket, where
transmission oil entering the hydraulic element as-
sembly (3) and flowing out to exhaust port through
the element, and flows to hydraulic pump. This time,
sludge is filtered at element. To sense filter clogged,
it is attached with vacuum sensor and temperature
sensor.
• Vacuum sensor is always set to OFF at less than
500 30 Hg and temperature sensor at less than 53.
To operate transistor switch, two switches turned
ON and oil filter warning light illuminated if tem-
perature exceeding 53 and pressure exceeding
500 ± 30 Hg.
CHECK:
• To prevent hydraulic filter damaged due to hydrau-
lic system, always replace oil filter if filter warning
light illuminated or whenever 200 hours used.
