• Drive  the  machine  as  straight  as  possible.  Do  not  turn  only  in  either  direction  but  turn  in  both  directions

evenly. Also, secure turning radius as large as possible.

• Clear the travel ground and remove obstacles so that the machine does not ride over large boulders or ob-

stacles.

• On slopes, do not work across the slope surface but work

upward  or  downward.  When  stopping  the  machine  on  a
slope, direct it up or down.

• If the ground slants to the right or left while the machine is

digging, do not stay there but move back to a level place,
then start digging again.

• If  the  idler  or  sprocket  floats  because  of  a  hard  obstacle

during dozing or ripping work, avoid that obstacle, since it
is “difficult to move it”.

METHOD FOR CHECKING AND ADJUSTING

• Adjust the track tension to a proper level.

Check  the  tension  by  measuring  clearance  (A)  between
the idler and carrier roller shown in the figure. This clear-
ance should be 20 to 30 mm usually. However, tense a lit-
tle higher for rocky terrain and a little lower for clay land.
Extremely low track tension can cause abnormal vibration
or abnormal wear of sprocket teeth.
For the testing and adjusting method, see “METHOD FOR
CHECKING AND ADJUSTING TRACK TENSION”.

• Check the idler and rollers for oil leakage and loose bolts

and nuts.
Repair any abnormality immediately.

• Check  a  clearance  (B)  between  front  idler  guide  plate  (1)

and track frame (2).
As clearance (B) becomes larger, it can cause the front id-
ler to sway sideways and cause the track shoe to jump off
rollers.
For the testing and adjusting method, see “METHOD FOR
ADJUSTING IDLER CLEARANCE”.

METHOD FOR CHECKING AND REPAIRING

Frequent inspection and prompt repair will reduce repair costs.
The following items for inspection will serve as a guide to maintenance service of each undercarriage part. Per-
form periodical inspection and contact the Komatsu distributor in your area when machine has approached re-
pairable limits and reversing limits.
