3)
Run the engine, push up the track shoe on
the side to be measured with the work
equipment, and prepare for running track
shoe idle.
q
When measuring front circuit: Right
track shoe
q
When measuring rear circuit: Left
track shoe
k
Since the raised track shoe will be
run idle during measurement,
secure a sufficient working area.
4)
Set the working mode in the power mode
(P) and set the travel speed in the High
position.
5)
Run the engine at high idle, set all the
levers and pedals for work equipment con-
trol, swing control, and travel in neutral,
and measure the oil pressure at each
speed. Then, operate the travel lever to
run the track shoe idle and measure the oil
pressure.
k
While checking the safety around
the machine extremely, run the
track shoe pushed up idle.
a
Do not operate the travel lever to the
stroke end (but stop it halfway).
a
Measuring condition and method of
judgment: If the pressures are in the
following ratio, the LS valve is normal.
6)
After finishing measurement, remove the
measuring tools and return the removed
parts.
3.
Measuring LS-EPC valve output pressure
1)
Open the side cover of the pump room
and remove oil pressure pickup plug (7).
2)
Install nipple
M3
and connect them to oil
pressure gauge [2].
a
Use the oil pressure gauges of 5.9
MPa {60 kg/cm
2
}.
