8. Fit tooth (1) to adapter (4), and confirm that when the
pointer is pressed strongly, the rear face of the hole for the
pin of the teeth (1) is at the same level as the rear face of
the hole for the pin of the adapter (4).
If the rear face of the pin hole of tooth (1) protrudes in front
of the rear face of the pin hole of adapter (4), do not knock
the pin in.
If this happens, there is something (C) preventing the tooth
(1) from fitting completely in adapter (4), locate the problem
and remove the obstruction. When tooth (1) fits completely
in adapter (4), knock in lock pin (2).
9. Insert lock pin (2) in the pin hole in the tooth (1), and knock
it in so that the top surface of lock pin (2) is the same
height as the surface of tooth (1).
10. After replacing a bucket tooth, always check the following.
1) After the lock pin (2) has been knocked in completely,
check that it is secured by the teeth (1) and surface.
2) Lightly hit lock pin (2) in the reverse direction from which it
was hit in.
3) Lightly hit the tip of the teeth (1) from above and below,
and hit its sides from right and left.
4) Confirm that rubber pin lock (3) and lock pin (2) are set as
shown in the figure.
REMARK
If the tooth is turned, the wear will become uniform. This will extend the service life of the tooth and reduce the fre-
quency of replacement.
When replacing the tooth, replace the rubber pin lock and lock pin with new parts at the same time. This will pre-
vent the tooth from falling out.
