METHOD FOR CHECKING LOOSENESS AND TIGHTENING ROAD LINER SHOE
BOLTS
NOTICE
If the machine is used with road liner shoe bolts loose, they will break. Tighten any loose shoe bolts
immediately.
1.
Check for looseness of the road liner shoe bolt (1).
2.
If any looseness of the bolt is found, tighten it in order
shown in the figure.
Tightening torque: 176.4 to 215.6 Nm
3.
Check that the nut and shoe are in close contact with the
link contact surface.
METHOD FOR CHECKING AND ADJUSTING TRACK TENSION
The wearing of the pins and bushings in the undercarriage depends on the working condition and type of soil.
Check the track tension occasionally and keep it in the standard range.
For performing the inspection and adjustment of the track shoes, park the machine on the level and solid
ground.
METHOD FOR CHECKING TRACK TENSION
1.
Run the engine at low idle, then move the machine forward for a distance equal to the track length on
ground, and slowly stop the machine.
2.
Place straight wooden square bar (3) which reaches from
idler (1) to carrier roller (2) on the track.
3.
Measure the maximum deflection (a) between the bottom
surface of the wooden bar and top surface of the track
shoes.
Standard deflection
Deflection (a) should be 10 to 30 mm.
If the deflection is out of the standard range, adjust it into the standard range.
METHOD FOR INCREASING TRACK TENSION
Prepare a grease pump.
