ADJUST BUCKET CLEARANCE 4
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 (1) securely to the LOCK
position (L).
1. Set the work equipment to the position shown in the dia-
gram on the right, then stop the engine and set the lock
lever to the LOCK position.
2. Shift O-ring (1) of the linkage and measure the amount of
play “a“.
Measurement is easier of you move the bucket to one side
or the other so all the play can be measured in one place.
(In the diagram this is on the left-hand side)
Use a gap (clearance) gauge for easy and accurate mea-
surement.
3. Loosen 4 plate mounting bolts (2) and loosen plate (3).
4. Remove shim (4) corresponding to the amount of play “a“
measured above.
[Example]
In the case of play of 3 mm, remove two 1.0 mm shims and
one 0.5 mm shim. Play becomes 0.5 mm. For shim (4), two
types of 1.0 mm and 0.5 mm are used.
When play “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.
