MAINTENANCE
When Required
Adjusting the gap between the
bucket and arm
WARNING
�
Before performing maintenance or
repairs under the machine, set all
working equipment against the ground
or in the lowermost position.
�
To prevent unexpected movement,
securely block the working equipment
when adjusting.
1. Ground the bucket as shown on the
diagram above in a stable position.
2. Check that the bucket dose not move,
then set the safety lock lever to the locked
position and stop the engine.
3. Slide the O-ring (1) to bring the gap (A) into
view and measure the width of the gap
(A).
The gap (A) should be 0.5 mm (0.02 in.)
Swing the bucket slightly to the left and
lightly press the arm point to the left side of
the bucket (the side without an adjuster).
4. Remove the three bolts (2), the end plate
(3) and flange (4).
5. Extract adjustment shim (5) from between
flange (4) and the bucket body according
to gap (A).
Adjustment shim thickness : 0.5 mm (0.02
in.)
Be careful that the gap is no less than 0.5
mm (0.02 in.) after adjustment.
Note: Example (for a gap of 2 mm or 0.08
in.)
2 mm – 0.5 mm (standard value)
= 1.5 mm (0.06 in)
In the above example, three shims (5) should
be removed.
6. Insert adjustment shim (5) removed in
step 5 above between end plate (3) and
flange (4) and fasten it in place with the
three bolts (2).
• Tightening torque for bolts (2)
83.4 N·m (61.5 ft-lb.)
7. Return the O-ring (1) to their original
position.
