MAINTENANCE PROCEDURE
ADJUST BUCKET CLEARANCE
WARNING
It is dangerous if the work equipment is mistakenly moved when adjusting
the bucket clearance.
Set the work equipment in a stable condition, stop the engine, then set
safety lock lever securely to the LOCK position (L).
1.
Set the work equipment in the position shown in the diagram on
the right, then stop the engine and set the lock lever to the
LOCK position (L).
2.
Shift O-ring (1) of the linkage and measure the amount of
clearance "a".
Measurement is easier of you move the bucket to one side
(right side of the diagram) or the other so all the clearance can
be measured in one place.
Use a gap (clearance) gauge for easy and accurate
measurement.
3. Loosen 4 plate mounting bolts (2), and loosen plate (3).
The shim is a split type, so the operation can be carried out
without removing the bolts.
4. Remove shim (4) corresponding to the amount of clearance "a"
measured above.
[Example]
In the case of clearance of 3 mm (0.118 in), remove two 1.0
mm (0.039 in) shims and one 0.5 mm (0.020 in) shim. Play
becomes 0.5 mm (0.020 in). For shim (4), two types of 1.0 mm
(0.039 in) and 0.5 mm (0.020 in)are used.
When clearance a is smaller than one shim, do not carry out
any maintenance.
5. Tighten the four bolts (2).
If the bolts (2) are too stiff to tighten, pull out pin stopper bolt (5)
for easier tightening.
