REMARK
• Perform installation in the reverse order to removal.
• Fit the O-ring (7) to the bucket (6) as shown in the fig-
ure since it is damaged easily when bucket (6) is in-
stalled. After inserting the pin, fit it in the regular
groove (C).
• Install the stopper plate (8) and bolt (9) for each pin,
then grease the pins.
• Lubricate with grease thoroughly until the grease
comes out from the end faces.
• If the dust seal is damaged when replacing the bucket,
replace it. If a damaged one is used without being re-
placed, sand and dirt may enter the part of pin and
cause abnormal wear of the pin.
