SERVICE PROCEDURE
REPLACE BUCKET TEETH
(If equipped)
ONE-PIECE TOOTH
When the bucket teeth are worn, replace them as follows.
1.
Raise the bucket to a suitable height, then put blocks (A) under
the bucket to prevent the bucket from coming down.
Raise the bucket so that the bottom surface of the bucket is
horizontal.
2. Remove the bolt and nuts (1) and (2), then remove bucket
tooth (3).
3.
Clean the installation surface of bucket tooth (3).
4. Install new teeth to the bucket.
When doing this, insert shims so that there is no clearance
between the teeth and the top surface of the bucket.
Continue to add shims until it becomes impossible to add a 0.5
mm (0.02 in) shim.
If the mounting surface is worn, correct the mounting surface
before installing the teeth.
5.
To prevent any gap from forming between the teeth and tip of the bucket, tighten bolts and nuts (1) and (2)
temporarily, then hit the tip of the teeth with a hammer.
Tightening torque of mounting bolt (1): 637 ± 853 Nm (65 ± 87 kgm, 470.1 ± 629.3 lbft)
(2): 618 Nm (63 kgm, 455.7 lbft)
