Measurement:
Amount of oil drained while travel motor is rotating
90° to 110°
CAUTION
Prevent personal injury. Always make sure that
the area is clear and that coworkers are out of the
swing area before starting the measurement.
When working around moving parts is unavoid-
able, pay special attention to ensure that hands,
feet, and clothing do not become entangled.
Securely support the raised track using wooden
blocks.
(1) Start the engine. Jack up the measuring side
track using the front attachment, as illus-
trated.
(2) Rotate the raised track with the travel lever
operated full stroke. Start measurement after
the track rotation speed reaches a constant
speed. Measure the drain oil amount and the
measuring time.
(3) Repeat the measurement at least three times
in both forward and reverse directions, and
calculate the average value.
(4) The measuring time should be more than 45
seconds.
Evaluation:
Refer to the Performance Standard Table in Group
T4-2.
The total performance of the travel motor should be
evaluated by referring to the test results of travel
speed and mistrack.
* Conversion of the amount of drain oil measured
into the per-minute value
First measure the amount of drain oil using a cali-
brated container. Then, convert the measured drain
oil into the per-minute value using the formula below:
∆
Q = 60 x q / t
Where:
∆
Q : Amount of drain oil per minute (L/min)
t : Time measured (seconds)
q : Total amount of drain oil (L)
