Bucket Replacement And Inversion - Komatsu ecot3 Operation And Maintenance Manual

OPERATION

BUCKET REPLACEMENT AND INVERSION

When pins are knocked in with a hammer, pieces of metal may fly and cause serious injury.
When carrying out this operation, always wear goggles, hard hat, gloves, and other protective equipment.
When the bucket is removed, place it in a stable condition.
If pins are hit with a strong force, there is a hazard that the pin may fly out and injure people in the surrounding area. Make sure
that there is no one in the surrounding area before starting the operation.
When removing the pins, do not stand behind the bucket. In addition, be extremely careful not to put your foot under the bucket
while standing at the side for the work.
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 lead and follow
that person's instructions and signals.
Replacement
1. Place the bucket in contact with a flat surface.
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 remove 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 on the stopper bolt for arm pin (A) and
link pin (B), remove the bolt, pull out arm pin (A) and link pin (B),
and then remove the bucket.
3. Align the arm (5) with holes (1) of the replacement bucket and
the link (6) with holes (2), then insert grease-coated pins (A)
and (B) into hole (1) and hole (2) respectively.
