Key Notes:

• Part Number: 213-6682 (Caterpillar reference 213-6682)
• Weight: 0.92 lbs
• Application: Boom and dipper cylinder eye - Caterpillar's own name for this part is a sleeve bearing for the cylinders in the boom and stick. One part number serves the 65 mm pin eye on both cylinders.
• Location: Backhoe end, inside the cylinder eyes. Each cylinder also has a 70 mm eye at its other end, which takes a different bushing - 212-8960 on the boom cylinder and 215-1906 on the dipper cylinder.
• Dimensions: 65.33 mm inside diameter, 78.125 mm outside diameter, 38 mm long
• Measure Before Ordering: 214-2255 shares this bore and outside diameter and is 35 mm long. It is the small frame version of the same joint, for the 415, 416 and 422E and 428E machines. Three millimetres is easy to miss by eye - go by your model first.
• Style/Type: Straight steel sleeve, no grease hole, no cross holes
• Quantity: Two required per joint. Sold individually.
• Interchange Numbers: Mates Caterpillar linkage pin 213-6696
• Manufacturer: Also catalogued by Caterpillar for the 517 and 527 track skidders
• 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 either the boom cylinder or the dipper cylinder knocks at its 65 mm pin, when a cylinder eye has begun to elongate, or when the pin will not stay greased. Because one part covers both cylinders, most shops buy four and do the whole boom at once while the machine is apart.

Why Choose Broken Tractor?

• ✅ One Number Covers Both Cylinders: Caterpillar books this bushing for the boom cylinder and the dipper cylinder together, so a full boom rebuild is one line item instead of two.
• ✅ Large Frame Version Of The Joint: 38 mm for the 420 and 450 class machines. The 415, 416, 422E and 428E take the 35 mm 214-2255 at the same joint, and we say which is which.
• ✅ Pin Number Printed On The Page: Linkage pin 213-6696 is the mating part, so the pin and the bushings go in the same box instead of the same job twice.
