(1) Shift O-ring (3) toward the bucket boss, using a spatula. (a-->b)
(2)When adjusting clearance (B), bring the nonadjusting side of the bucket in contact with the arm.
(3)Measure clearance (B) and check that it is within 1.0 mm (0.04 in).
(4) Adjust clearance (B) where it is more than 1.0 mm (0.04 in).
(5) An average of 5 shims (9) of 1mm (0.04in) thickness are set in the plate (8) fixed by the three capscrews (11). The clearance can be decreased by 1mm (0.04in) if one shim is removed.
