MAINTENANCE
METHOD FOR REPLACING TIP TYPE TEETH
Replace the tooth before the wear reaches to the adapter.
1.
Raise the bucket to a suitable height, then put a block (A)
under the bucket to prevent the bucket from lowering.
Set the bottom of bucket to be level, and put a block under
the bucket at the center.
2.
Lower the bucket on the block and stabilize it.
3.
Stop the engine.
4.
Fit the round bar which is slightly thinner than pin (1) to the
end of pin (1), and hit the round bar with the hammer to
drive out the pin.

If it cannot be removed by this method, ask your Komatsu
distributor to have the replacement performed for safety.

REMARK
The wear will become uniform by rotating the mounting position of the tooth. This will extend the service life of
the tooth and reduce the frequency of replacement.
1.
Raise the bucket to a suitable height, then put a block (A)
under the bucket to prevent the bucket from lowering.
Set the bottom of bucket to be level, and put a block under
the bucket at the center.
2.
Lower the bucket on the block and stabilize it.
3.
Stop the engine.
4.
Fit the socket wrench to the shaft of pin (1), and turn it
counterclockwise by 90 ° to unlock the pin (1).
