4.1 TRACK TENSION
Track systems use a grease cylinder to keep the track chains in tension. Loss of tension in the
tracks can result in the sprocket jumping in the belt lugs, and also allows the belt to run off of
the idler/sprocket. This can hinder the tracking ability of the machine and damage many of the
components of the track systems if not resolved quickly.
The tension of the tracks should be checked on a regular basis according to the parameters set
out in Section 2.3 of this manual; Checking Track Tension. If the tension of the track is outside
these parameters, and the adjustment method given in Section 2.3 has no effect, please read
below checks that can be made to identify possible causes:
Check 1:
With the tensioner access plate removed (see Section 2.4.1), make a visual inspection of
the greaser, looking for any signs of leaking grease.
Possible Cause:
If grease is leaking from the base of the greaser; where it screws into the end of the
tensioner; either the gasket has failed and needs replacing, or the greaser is not screwed in
properly and needs tightening.
If grease is leaking from the end of the greaser where the grease gun connects to it, the
greaser valve has failed and should be replaced.
Check 2:
When the machine is stationary and blocked, make a visual inspection of the belt below the
adjusting end of the tensioner, looking for any signs of leaking grease.
Also, reach under the frame, feel the adjusting end of the tensioner for any grease.
Possible Cause:
If grease is leaking from the adjusting end of the cylinder, the seals may have failed. This
requires the tensioner to be removed from the track frame and replacing with a new unit.
