replaced. If the core bars break on the wings, the track can
still be used but note that eventually long term damage will
occur.
Core Bars - Fast Abrasion
Cause:
1 The sprocket is not correct for the track.
2 The teeth of the sprocket are worn (hook shaped).
3 Operating environment is extremely abrasive
Prevention:
1 Make sure that the sprocket is genuine JCB, ensure
sprocket is in good condition.
2 Replace sprocket. When new tracks are fitted, the
sprockets should always be checked (and renewed if
necessary).
3 Clean the tracks with fresh water.

Additional Notes:
When the core bars are worn out, the track must be
replaced. The track does not have to be replaced if the
core bar abrasion is below approximately 20%.
