WARNING
• When pins are knocked in with a hammer, pieces of metal may fly and cause serious injury.
When performing this operation, always wear goggles, hard hat, gloves, and other personal protec-
tive items.
• Place the removed bucket in a stable condition.
• The pin is hit with a strong force to remove, so the pin may fly out and injure people in the sur-
rounding area. Make sure that there is no one in the surrounding area before starting the work.
• When removing the pins, do not stand behind the bucket. In addition, be extremely careful not to
put your foot on the side of the bucket.
• When removing or inserting pins, be extremely careful not to get your fingers caught.
• Never insert your fingers into the pin holes when aligning the holes.
Stop the machine on a firm and flat surface and do the work. When performing joint work, appoint a leader and
follow that person's instructions and signals.
Replace
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.
NOTICE
After removing the pins, make sure that mud or sand does not get on them. Dust seals are fitted at both
ends of the bushings, be careful not to damage them.
2.
Remove the double nut of stopper bolt at arm pin (A) and
link pin (B), then pull out the bolts.
3.
Pull out arm pin (A) and link pin (B), then remove the buck-
et.
