Adjust the Bucket Clearance
The standard bucket has a bucket clearance adjusting
mechanism to prevent backlash.
1. Bring the back of the bucket into slight contact with
the ground, and swing the machine a little to the right
to make the condition where the top of the arm is
pressed against the inside of the clearance adjusting
mechanism.
2. Stop the engine.
3. Move the O-ring to above the boss and measure the
clearance of the bucket and arm.
4. Remove the shim to adjust the clearance if the
clearance is 1 mm or more.
The thickness of the shim is 0.8 mm. Do not remove
the shim if the clearance is 0.8 mm or less.
5. Remove the four bolts. Remove as much shims as
the amount of backlash (wear amount) from inside
the flange.
6. Attach the flange. Tighten the four bolts.
7. Measure the clearance.
The standard clearance is 0.1 to 1.3 mm.
