[5] CHECKING AND RE-TIGHTENING RUBBER TRACK BOLTS
Using the Machine while its rubber track bolts (1) are left
loosened will cause the bolts to break, fasten each of the
loosened bolts.
[METHOD FOR RETIGHTENING BOLTS]
1. After tightening the bolts with a tightening torque of
196 +/-19.6N · m [20+/-2kgf · m] first, ensure that the
nuts and shoes are a tight fit to the link mating surface.
After checking, re-tighten them at a tightening angle of
90+/-10 degrees.
[TIGHTENING SEQUENCE]
Tighten the bolts in the order indicated in the diagram on
the right.
After tightening, check to ensure that the nuts and shoes
are a tight fit to the link mating surface.
[6] CHECKING/ADJUSTING RUBBER TRACK TENSION
The pins and bushings around the footage of the Machine shows varied states of abrasion
depending on the working conditions and soil quality. Check the tension of rubber track at any
time to maintain the standard tension.
Conduct the inspection and adjustment on flat and solid ground.
[INSPECTION]
1. Keep the engine revolution in an idling state to allow
the Machine to go forward for a distance equal to the
length of rubber track in contact with the ground, and
slowly stop travelling.
2. Place a square bar (3) that can bridge between idler
(1) and upper rolling wheel (2) on the rubber track.
3. Measure the maximum sagging dimension between
the upper plane of rubber track and the bottom surface
of the square bar.
Reference value of sagging dimension (a): 10 to 30
mm is a normal range.
