Checking And Adjusting The Rubber Track Tension - Maeda MC-104C-2 Operation Manual

[3] CHECKING AND ADJUSTING THE RUBBER TRACK TENSION

・For performing rubber track check and adjustment, set up outrigger and lift the machine so that its tracks are
about 50mm off the ground.
・Tension of rubber track is normal, if the clearance between bottom of track roller and shoulder of track is 5 to
10mm at midway.
・In case track is loose even after packing the grease, it will be necessary to replace the rubber track or the seal of
tension adjust cylinder. For the judgment of whether to replace, repair or continue to use the existing track,
contact your dealer.
Because the progress of rubber track wear will vary depending on working conditions or ground, always watch the
wear and tension. Particularly in case new machine or new track has been installed, after adjusting the tension to
specified value, keeping to travel for 5 to 30 hours will cause initial slack to develop. Until such initial slackening
period elapses, tension adjustment has to be carried out diligently. It helps avoid track coming off due to lack of
tension.
[CHECKING THE TENSION]
1. Move the machine so that joint (M mark) of rubber track comes over
the center between the shafts.
2. Set up outrigger and lift the track by about 50mm off the ground. For
details of outrigger setting up method, see "OPERATION, 2.12
SETTING UP THE OUTRIGGER".
3. Measure the clearance between bottom of the track roller in the
middle and shoulder of the rubber track.
If the clearance is 5 ~10mm, the tension falls within the standard.
4. If the tension is out of such standard, make adjustment in accordance
with Tension Adjustment in the next page.
