(A) Rubber crawler :
108 to 118 mm (4.3 to 4.7 in.)
(B) Steel crawler :
172 to 192 mm (6.8 to 7.6 in.)
< TB180FR >
(A) Rubber crawler :
160 to 180 mm (6.3 to 7.1 in.)
(B) Steel crawler :
260 to 280 mm (10.2 to 11.0 in.)
Adjustment < TB180FR >
TB180FR uses a hydraulic cylinder to adjust
the tension of the crawler belts. Note that it
is not necessary to regularly perform
adjustments of the tension of the belt itself.
Adjustment < TB153FR >
Increasing the tension
1. Remove the cover (1).
2. Using the grease gun, insert grease
through the grease nipple (3) in the grease
discharge valve (2).
3. Inspect the crawler tension.
Decreasing the tension
1. Remove the cover (1).
2. Using the Spanner, slowly loosen the
grease discharge valve (2) and drain the
grease.
If the grease does not drain easily, move
the machine forward or backward.
3. Tighten the grease discharge valve (2).
