COMPONENT TEST
Measurement:
1. Amount of Oil Drained While Swinging the
Upperstructure
(1) Fully retract the arm cylinder. Fully extend the
bucket cylinder. Raise the boom so that the
arm tip pin height is the same as the boom foot
pin height. Be sure that the bucket is empty.
(2) Start the engine. Operate and hold the swing
lever full stroke. Start draining oil measure-
ment after the swing speed reaches a constant
maximum speed. The measuring time should
be more than 45 seconds.
(3) Repeat the measurement at least three times
in both clockwise and counterclockwise direc-
tions, and calculate the average values.
2. Amount of Oil Drained While Relieving Swing Motor
Circuit
(1) Thrust the bucket teeth into the ground as
illustrated so that the upperstructure does not
rotate when the swing lever is operated full
stroke.
(2) Start the engine. Operate and hold the swing
lever full stroke. Start drain oil measurement
when drain oil starts coming out of the drain
hose end. The measuring time should be more
than 45 seconds.
(3) Repeat the measurement at least three times
in both clockwise and counterclockwise direc-
tions, and calculate the average values.
Evaluation:
Refer to the Performance Standard Table in Group
T4-2.
* Conversion of the amount of drain oil measured into
the per-minute value
First measure the amount of drain oil using a calibrated
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)
