Komatsu PC27R-8 Operation & Maintenance Manual page 143

5 - If the rubber track tension is not sufficient after having been
adjusted through the injection of grease, check the idler gas-
kets and if necessary change them or change the track.
(See "4.7.1.f CHECKING THE RUBBER TRACK TEN-
SION").
IMPORTANT
If the track tension is adjusted so that the shoe may come
off its seat, the track may be lengthened and the idler cyl-
inder may be damaged, too.
6 - If the break between the support claws of the rubber tracks
reaches a length (1) of approximately 60 mm, the track must
be repaired.
It must be immediately repaired even when the break is very
slight, but the steel reinforcement units can be seen.
IMPORTANT
If the break length (2) is inferior to 30 mm, or its depth is
inferior to 10 mm, the track does not need repairing.
For any change or repair, contact your Komatsu Utility
Dealer.
