OPERATION
TIPS FOR LONGER UNDERCARRIAGE LIFE
2
Undercarriage life varies greatly depending on operation method, in-
spection and maintenance. Track components have a certain dimension
when new.
As wear occurs dimensions will decrease (or increase in case of track
pitch and front idler flange height) until a decision must be made wheth-
er to rebuild or recondition components, replace them or run them to de-
struction.
For each component or condition, five different dimensions are mea-
sured. 100% is dimension of component when new. 075%, 050% and
025% indicate percentage of wear remaining before a maintenance ac-
tion should be taken. 000% is point at which either maintenance must
take place or components run to destruction.
For most efficient operation, keep the following points in mind.
OPERATION METHOD
2
•
Select the track shoe that best suits the type of soil to be encoun-
tered in service. Please consult your distributor when selecting
track shoes.
•
Do not allow shoe slipping to occur during operation. If shoe slip-
ping occurs, reduce load to the blade until slipping stops.
•
Avoid sudden starts, acceleration or stops, unnecessarily high
speeds and sharp turns.
•
Always operate machine in a straight line whenever possible. When
making turns, be careful not to allow the machine to stay to one
side, so operation in both turning directions can be done properly.
Make turns with the largest possible radius.
•
Prior to operation, clear boulders and obstacles to prevent machine
from riding over them while operating.
•
On a slope, operate the machine parallel to the inclination of the
slope. Do not operate across the slope. Also when stopping the
machine on a slope, the machine should face toward the top of the
slope.
•
When ground inclines to left or right during digging operation, do
not continue to dig with machine inclined. Move machine back to
level ground and start to dig again.
•
When idlers or sprockets are lifted due to obstacles during dozing,
do not attempt to force the machine to perform. Work at this time
exceeds machine working capability.
