Key Notes:

• Part Numbers: T64493
• Type: Upper articulation pivot shim — circular, with spaced bolt holes
• Thickness: 0.25 mm (0.01 in)
• Quantity Required: Sold individually — the number used varies with wear, so order enough to set the correct pivot clearance
• Weight: 0.13 lbs (0.06 kg)
• Companion Part: The thicker 0.02 in upper pivot shim is T64492 — combine the two thicknesses to fine-tune the shim stack
• Serial Number Notes: Serial limits are shown with each model above. All other models listed fit every serial number.
• Application: Stacks under the upper articulation pivot cap at the engine frame pivot hole, setting the clearance of the upper articulation joint on John Deere loaders, skidders and feller bunchers.
• Condition: Replacement Part for John Deere Equipment

Common Use Case or Symptoms: Use when resetting upper pivot clearance during an articulation joint rebuild, or when there is play or clunking at the upper pivot — the thin 0.01 in shim lets you dial in the final clearance after the thicker shims are set.
