1. Place the bucket on a level ground.
Remark:
Before removing the pin roll, slowly lower the
bucket to a level where it just contacts the
ground.
If a larger force is used to lower the bucket to
the ground, resistance could increase on the
pin roll, causing dif
fi
culties while removing it.
Note:
Make sure the pin roll is free from mud or sand
after removal.
Both ends of the bushing are installed with
seals against dust. Be careful not to damage
them.

retaining arm pin (A) and link pin (B), take
out arm pin (A) and link pin (B), and then
remove the bucket.

replacement and the link (6) with bore (2).
Insert the greased pin rolls (A) and (B) into
