MAINTENANCE PROCEDURE
REPLACE BUCKET TEETH (HORIZONTAL PIN TYPE)
WARNING
It is dangerous if the work equipment moves by mistake when the teeth
are being replaced.
Set the work equipment in a stable condition, then stop the engine and
set the lock lever securely to the LOCK position.
The pins can be knocked out only with strong force, so there is a hazard
that the pin may fly out. Check that there is no one in the surrounding
area.
There is a hazard that fragments will fly during the replacement work, so
always wear protective equipment like safety glasses and gloves.
Replace the bucket teeth before the adapter starts to wear.
1. In order to enable tooth pin (1) to be pulled out, put a block
under the bucket bottom and make sure that the work
equipment rests on it securely. Then move the lock lever to the
LOCK position. In that case ensure that the bucket is level on
the block.
2. Place a bar on the head of pin (1), hit the bar with a hammer to
knock out the pin, then remove tooth (2).
REMARK
Use a round bar of a diameter smaller than the pin.
If it cannot be removed in this way, to ensure safety, please
contact your Komatsu distributor and ask them to carry out the
replacement work.
3. Clean the mounting face. Fit a new tooth (2) in the adapter,
push in pin (1) partially by hand, then lock it with a hammer to
install the tooth to the bucket.
