MAINTENANCE PROCEDURE
REPLACE BUCKET TEETH
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, stop the engine, then set
the lock lever securely to the LOCK position (L).
The pin is knocked out by force, so there is danger of the pin flying out.
Check that nobody is in the surrounding area.
There is danger of broken pieces flying during the replacement
operation, so wear protective glasses, gloves, and other protective
equipment.
REMARK
For machines equipped with a cab, there is only a lock lever on the left.
Replace the bucket teeth before the adapter starts to wear.
1. To make it possible to knock out the pin of tooth (1), set the
bottom surface of the bucket on a block, check that the work
equipment is in a stable condition, then set the lock lever to the
LOCK position (L).
Set so that the bottom face of the bucket is horizontal.
2. 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.)
3. After removing lock pin (2) and rubber pin lock (3), check them.
If lock pins and rubber pin locks with the following defects are used, the teeth may come off the bucket. Replace
them with new ones.
The lock pin is too short.
