Pin 2375090 works with bushings in the arm and bucket. During installation, a locking bolt is required to secure the flag, and potentially shims to eliminate side play.
Operating a machine with a loose pin or unsecured flag can lead to the pin falling out and uncontrolled detachment of the bucket. This risks equipment damage and poses a danger to the surroundings.
This pin connects the bucket to the digging arm or the link. It is the load-bearing component of the entire working attachment.
