MAINTENANCE PROCEDURE
REPLACE BUCKET TEETH (HORIZONTAL PIN TYPE)
Replace the bucket teeth before the adapter starts to wear.
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.
1. To make it possible to knock out pin (1) of tooth (2), put block
(5) under the bottom of the bucket, and set so that the bottom
surface of the bucket is horizontal.
2.
Check that the work equipment is in a stable condition, then set
the lock lever to the LOCK position (L).
3.

knock out the pin, then remove tooth (2).
REMARK
If the bucket teeth cannot be safely removed by this mothod,
have your Komatsu distributor replace the bucket teeth.
