MAINTENANCE SERVICE PROCEDURE
265
REPLACE BUCKET TEETH (HORIZONTAL PIN
TYPE)
Replace the point before the wear reaches the adapter.
WARNING
●
It is dangerous if the work equipment moves by mistake
when the teeth are being replaced. Set the work equip-
ment in a stable position, then stop the engine and raise
the safety lock lever to the LOCK position.
●
If the locking pin is knocked out with excessive force,
there is a hazard that the pin may fly out. Check that
there is no one in the surrounding area.
●
Pieces will often fly during the replacement operation, so
wear safety glasses, gloves, and other protective equip-
ment.
1. Set the bottom of the bucket on a block to make it possible to
remove pin (1), check that the work equipment is stable, then
raise the safety lock lever to the LOCK position.
Set so that the bottom of the bucket is horizontal.
2. Place a bar on the pin head and strike the bar with a hammer
to knock out pin (1). Remove tooth (2).
REMARK
Use a round bar with a smaller diameter than that of the pin.
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.
