4. When one or more steel cores have come off the track or are
pushed out due to excessive tension.
5. If the rubber track cannot be tensioned correctly through the
injection of grease, check the track tensioner gaskets and if
necessary change them or even the track.
(See "4.9.1.g CHECKING AND ADJUSTING THE RUBBER
TRACK TENSION").
IMPORTANT
q
If the track tension is such that the track may come off its
seat, the track may be lengthened and the track tensioner
cylinder damaged.
6. If the broken area between the rubber track claws reaches a
length of approximately 60 mm, the track must be repaired.
It must be immediately repaired also when the steel cores are
visible, even if the broken area is very small.
IMPORTANT
q
If the length of the broken area is less then 30 mm or its
depth is less than 10 mm, it is not necessary to repair the
track.

For any repair or replacement, contact your Komatsu Dis-
tributor.
