4.
Align arm (5) with hole (1) of the replacement bucket.
5.
Align link (6) with hole (2) of the replacement bucket.
6.
Apply grease to pins (A) and (B) and insert them into
holes (1) and (2) of the bucket.
REMARK
• Perform installation in the reverse order to removal.
• Fit O-ring (3) to arm (5) as shown in the figure since it
is damaged easily when bucket (4) is installed.
After inserting the pin, fit it in the regular groove.
7.
Install the lock bolt and nut of each pin.
8.
Apply grease to each pin.
REMARK
• Lubricate with grease thoroughly until the grease comes out from the end faces.
• When replacing the bucket, replace the dust seal with a new one if it is damaged. If a damaged seal is
used without being replaced, sand and dirt may enter the pin portion and cause abnormal wear of the
pin.

WARNING
When reversing a bucket, there is the danger that the
bucket tooth tip overruns the normal trajectory and inter-
feres with the cab, thus causing a serious trouble.
Pay good attention to the work when reversing a bucket so
that the bucket and the cab may not interfere with each
other.
1.
Place the bucket in contact with a flat surface of the ground.
REMARK
When removing the pins, place the bucket so that it is in light contact with the ground.
If the bucket is lowered strongly to the ground, the resistance will be increased and it will be difficult to re-
move the pins.
