2）Low-pressure relief valve inspection
(Continued above high pressure relief
testing)
① Set the HST pedal and range gear change lever at
the neutral position.
② Read the pressure on the gauge. Pressure reading
should be 0.42-0.56 MPa{4.3-5.7 kgf/c ㎡}.
③ If the pressure gauge is too large range, stop the
engine and replace to small range oil pressure
gauge.
④ Start the engine, and set throttle speed to 2800rpm.
Set pressure
0.4～0.6 MPa
｛4.1－6.1 kgf/c ㎡｝
NOTE:
Never move the HST pedal to forward or reverse, for
prevent the oil pressure gauge from damage.
⑤ Read the pressure on the gauge. Pressure reading
should be 0.4-0.6 MPa{4.1-6.1 kgf/c ㎡}.
⑥ If the set value is not satisfied, replace the spring
of low pressure relief valve.
