2. Use the operating devices to lift the body.
Operate the levers slowly.
3. Inspect the gap (A or B) between the
bottom surface of the frame at the center
of the crawler frame and the top surface of
the crawler.
The gap (A or B) should be within the
following range:
(A) Rubber crawler:
77 to 87 mm (3.0 to 3.4 in.)
(B) Steel crawler:
144 to 154 mm (5.7 to 6.1 in.)
Adjustment
Increasing the tension
1. Remove the cover (1).
Inspecting and Adjusting the
Crawler Tension
¡
If you must work beneath the raised
machine or equipment, always use
wood blocks, jack-stands or other rigid
and stable supports. Never get under
the machine or working equipment if
they are not sufficiently supported.
This procedure is especially important
when working on hydraulic cylinders.
¡
The track adjuster contains highly
pressurized grease. If the tension is
adjusted without following the
prescribed procedure, the grease
discharge valve may fly off, resulting
in injury.
• Loosen the grease discharge valve
slowly.
• Do not put your face, arms, legs or
body in front of the grease discharge
valve.
Inspection
1. For rubber crawlers, move the machine so
that the “M” or “ ∞ ” mark at the coupling is
at the top center of the crawler frame.
