Forward and backward bucket
The steps to replace the bucket are as follows:
(1) The bucket is lowered on flat ground. In the process of lowering the bucket, make sure that the bucket is just in contact with the ground, so as to minimize the resistance when removing the pin shaft.
(2) Remove the stick pin and the linkage pin. Remove the double nuts of the locking bolt of the stick pin and connecting rod pin shaft, and then remove the stick pin and connecting rod pin shaft, and remove the bucket. In this process, pay attention to the removed stick pin shaft and connecting rod pin shaft not to be polluted by mud and sand, and the seal at both ends of the shaft sleeve should not be damaged.
(3) Install the bucket or other working device to be used. Change the position of the stick so that the hole on the stick is aligned with the hole on the bucket, and the hole on the connecting rod is aligned with the hole on the bucket, as shown in the figure on the right. Then apply grease and install the stick pin and connecting rod pin. The installation process of the pin shaft is opposite to the removal sequence. When installing the stick pin, install an O-ring at the position shown in the figure below. After inserting the stick pin, install the O-ring into the appropriate groove. When installing the connecting rod pin, first install the O-ring into the appropriate groove, and then insert the connecting rod pin.
(4) Install the locking bolts and nuts of each pin shaft, and then apply grease on the pin shaft
