Replace Bucket Teeth (Vertical Pin Type) - Komatsu ecot3 Operation And Maintenance Manual

MAINTENANCE PROCEDURE

REPLACE BUCKET TEETH (VERTICAL PIN TYPE)

Replace the bucket teeth before the adapter starts to wear.
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 of tooth (1), 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. Use a hammer and drift to knock out lock pin (2). (If the drift is
set against rubber pin lock (3) when it is hit, the rubber pin lock
may break. Set it against the back of the pin.)
4. After removing lock pin (2) and rubber pin lock (3), check them.
