  • Type: Upper machine frame (articulation) pivot pin
  • Dimensions: 7" long x 1-7/16" diameter
  • Weight: 3.70 lbs (1.68 kg)
  • Companion Part: The lower frame pivot pin for these skidders is AT113989 (replaces AT83055, AT42790)
  • Application: Joins the front and rear frames at the upper articulation pivot on John Deere log and grapple skidders, carrying the frames as the machine steers.
  • Condition: Replacement Part for John Deere Equipment

Common Use Case or Symptoms: Use when there is play or clunking at the articulation joint, the frames shift when steering, or the upper pin is worn, grooved or seized — a worn pivot pin wears out the frame bores and bushings.
