MAINTENANCE MAINTENANCE PROCEDURE REPLACE BUCKET TEETH (HORIZONTAL PIN TYPE) 4 Replace the teeth before the wear reaches the adapter. q It is dangerous if the work equipment is mistakenly moved when replacing the teeth. Set the work equipment in a stable condition, stop the engine, then set safety lock lever (1) securely to the LOCK position (L). q As the locking pin is knocked out with force, there is danger that the pin may fly out. Check that there is no one near the machine. q Broken pieces may fly during the replacement opera- tion, so always wear safety glasses, gloves, or other protective equipment. 1.
To make it possible to knock out the 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. Place a bar on the head of pin (1), hit the bar with a ham- mer to knock out the pin, then remove tooth (2). REMARK If it cannot be removed by this method, for safety reasons, always contact your Komatsu distributor to have the replace- ment carried out. 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. 4-35 WARNING
