(11) Pin
Hit pin (11) from the retainer side of the bucket in order to remove side protector (10) from side plate (8).
Clean side protector (10), pin (11), retainer (9) and side plate (8) before installation. Note: Lateral clearance between the side plate and the side protector should not exceed 1 mm (0.04 inch). Shims may be required in order to decrease the lateral clearance which will decrease movement. Install the shims between the side plate and the side protector on the opposite side of the retainer.
Put retainer (9) in side plate (8).
Align two pin holes of the new protector and the side plate. Hit the pin from the side of the bucket without the retainer. Note: If the pin and/or the retainer are worn, replace the pin and/or the retainer.
