REPLACEMENT
Due to possibility of flying metal objects, always wear
safety helmet, protective gloves and eye protection when
changing pins.
1. Inspect the bucket O-rings on a routine basis. If worn or
damaged, replacement is necessary.
2. Roll the old O-ring (1, Figure 4) onto the boss (2) around
the bucket pin (3). Remove the bucket pin and move the
arm or bucket link (4) out of the way.
3. Remove the old O-ring and temporarily install the new O-
ring (1, Figure 5) onto the bucket boss (2). Make sure that
the O-ring groove on both the bucket link (4) and boss
