Key Notes:

• Part Number: 213-6683 (Caterpillar reference 213-6683)
• Weight: 1.30 lbs
• Application: Boom at the dipper stick - the bushing at the boom tip pivot where the dipper stick hangs off the end of the boom
• Location: Backhoe end, boom tip. Two bushings per joint, one each side.
• Dimensions: 60.20 mm inside diameter, 73.11 mm outside diameter, 50 mm long
• Measure Before Ordering: 209-6181 is 60.22 mm bore and also 50 mm long, and it fits many of these same machines - but it is 73.612 mm on the outside against this part's 73.11 mm, and it goes at the BOOM FOOT, not the boom tip. Half a millimetre of outside diameter is the only measurable difference, so go by the joint first and the caliper second.
• Style/Type: Straight steel sleeve
• Quantity: Two required per joint. Sold individually.
• Serial Number Notes: Confirm your data plate prefix. No 415 or 416 of any generation takes this part.
• Material: Steel, low alloy
• Condition: Aftermarket replacement part
• Shipping Restrictions: Ships within the lower 48 United States only

Common Use Case or Symptoms:

Use when the dipper stick flops side to side at the boom tip, when the bucket wanders off line as you curl, or when the boom tip pin has worn a shoulder. This pivot takes the whole breakout load of the hoe and it is the joint operators notice first.

Why Choose Broken Tractor?

• ✅ Boom Tip Not Boom Foot: This is the pivot where the dipper hangs off the boom. The bushing at the other end of the boom, down at the swing tower, is 209-6181 - and it measures almost the same.
• ✅ Twenty Four Models On One Number: The 420 class through the 444F2, spanning base, E, F and F2 machines, on a single bushing.
• ✅ Half A Millimetre Called Out: The one dimension that separates this from the boom foot bushing is 0.5 mm of outside diameter. We print both numbers rather than let you find out on the bench.
