12. OPERATION 12.15.2 INVERSION 1. Place the bucket in contact with a flat surface. REMARK When removing the pins, place the bucket so that it is in light contact with the ground. If the bucket is lowered strongly to the ground, the resistance will be increased and it will be difficult to remove the pins. 2. Remove the stopper bolts and nuts, then remove pins A and B , and remove the bucket. NOTICE After removing the pins, make sure that they do not become contami- nated with sand or mud and that the seals of bushing on both sides do not become damaged. 3. Install the bucket inversely.
After the bucket is inversed, correct the inclination and direction of the retaining pin holes a and b and stabilise the bucket securely. 4. Align the arm with holes a and the link with holes b , then coat with grease and install pins A and B . REMARK Install the O-rings into retaining hole a of the arm and bucket. When installing the bucket, the O-rings are easily damaged, so fit the O-rings on the boss of the arm end as shown in the diagram. When knocking the pin, move the O-ring down to the regular groove. 5. Install the stopper bolts and nuts for each pin, then grease the pin. PC450-ENG 2-75
