Track to Machine Clearance

In order to avoid tracks hitting or fouling the machine bunk or bodywork (which can in extreme cases cause transmission problems), a minimum clearance gap of 50mm between track and machine should exist. The tracks should be properly tensioned at all times.

This clearance gap should be measured with:

  • The track pushed on the tyres towards the machine.

  • The bogey at maximum tilt angle – the worst possible scenario.

Without this clearance there is a possibility of track/machine fouling when tracks wear, become slack or are run at faster than normal speeds.
