2. Remove the stopper at the end of the pin, then pull out pins
(A) and (B) and remove the bucket.
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.
3. Align the arm (3) with holes (1) of the replacement bucket
and the link (4) with holes (2) , then insert grease-coated
pins (A) and (B) into hole (1) and hole (2) respectively.
REMARK
Carry out installation in the reverse order to removal.
When installing bucket (6), it is easy to damage the O-ring (7),
so fit O-ring (7) to bucket (6) in the position shown in diagram
on the right. After inserting pin, fit the O-ring correctly in the
groove.
Install the stopper bolts and nuts for each pin, then grease the
pin.
Add fresh grease sufficiently until it is pushed out of the edge.
If the dust seal is damaged when replacing the bucket, replace
it with a new one. If the defective dust seal is not replaced, dirt
and sand enter the pin portion and cause abnormal wear to the
pin.
