CHECKING THE RUBBER TRACKS 4
Change the rubber tracks when they reach the indicated wear limits.
1. When the height “A” of the rubber claw is less than 5 mm:
in this case, in fact, the track may slip and its traction force
be reduced.
1- Roller
2- Rubber track
2. When the steel core is visible in two or more points of the
track.
3. When more than half of the steel core cords at the centre
of the track are cut.
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 "CHECKING AND ADJUSTING THE RUBBER
TRACK TENSION (4-38)").
NOTICE
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.
