MAINTENANCE
•
After the lock pin (2) is driven in completely, its tip sur-
face is flush with the surface of tooth (1).
•
Lightly hit lock pin (2) in the reverse direction from
which it was hit in.
•
Lightly hit the tip of tooth (1) from above and below,
and hit its sides from right and left.
•
Confirm that rubber pin lock (6) and lock pin (2) are
set as shown in the right figure.
REMARK
If the tooth is turned, the wear will become uniform. This will extend the service life of the tooth and reduce the
frequency of replacement.
When replacing the tooth, replace the rubber pin lock and lock pin with new parts at the same time. This will
prevent the tooth from falling out.
METHOD FOR REPLACING BUCKET TEETH (HORIZONTAL PIN TYPE)
Replace the bucket teeth before the adapter starts to wear.
•
It is dangerous if the work equipment moves by mistake when the tooth is being replaced.
Set the work equipment in a stable condition, set the lock lever securely to LOCK position and stop
the engine.
•
As the pin is driven out with strong force, it is dangerous that the pin may fly out. Check that there
is no people in the surrounding area.
•
Broken pieces may fly during the replacement work, so always wear the protective equipment such
as protective eyeglasses and gloves.
1.
To pull out pin (1) of tooth (2), put block (5) under the bot-
tom of the bucket, and make the bottom surface of the
bucket horizontal.
2.
Check that the work equipment is in a stable condition,
then set the lock lever to LOCK position (L).
