Key Notes:

• Part Number: 458-0545
• Weight: 35.00 lbs (15.88 kg)
• Type: Bucket linkage pin — structural pivot pin in the front linkage assembly connecting the dipper arm to the bucket cylinder linkage
• Material: 4140 alloy steel, heat treated for extended wear life
• Application: Serves as the primary pivot at the bucket linkage connection point on the dipper arm; allows the bucket to curl and dump through its full range of motion during digging cycles
• Condition: Made in USA replacement part by Paint Valley Equipment

Common Use Case or Symptoms:
Use when the bucket has excessive play or slop during curling, there is metal-to-metal contact at the linkage joint, or grease no longer holds — worn or seized linkage pins cause imprecise bucket control and accelerated bushing and bore wear on the dipper arm.
