MAINTENANCE
Every 50 Hours
Inspecting and adjusting the
Crawler Tension
WARNING
¡¡
¡¡
¡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.
• If no grease is expelled when grease
discharge valve is loosened, there is
a problem. Contact your nearest
service outlet for repairs. DO NOT
disassemble, as this is very
dangerous.
Inspection
1. Lower the lift arm and tilt the bucket
forward to raise the front of the loader off
the ground as far as it will go.
2. Measure the clearance between the
center track roller and the surface of the
crawler belt where it makes contact with
the roller.
The gap (A) should be within the following
range:
15 to 25mm (0.6 to 1.0 in.)
Adjustment
Increasing the tension
3. Remove the cover.
4. Using the grease gun, insert grease
through the grease nipple in the grease
discharge valve (1).
5. Inspect the crawler tension.
Decreasing the tension
3. Remove the cover.
4. Using the L-type wrench, slowly loosen
the grease discharge valve (1) and drain
the grease.
If the grease does not drain easily, move
the machine forward or backward.
5. Tighten the grease discharge valve (1).
¡Tightening torque: 59 N·m (43.4 ft.lb.)
