Key Notes:

• Part Number: 326-3362 (Caterpillar reference 326-3362)
• Weight: 1.95 lbs
• Application: Boom cylinder rod end at the swing tower - the bushing inside the rod eye of the boom cylinder, where that rod pins into the swing tower
• Location: Backhoe end. The far side of this same joint, inside the swing tower, takes bushing 9R-0139. The other end of the cylinder, the base, pins into the boom.
• Dimensions: 55.37 mm inside diameter, 68.61 mm outside diameter, 91 mm long
• Style/Type: Hardened low alloy steel, greaseable - grease hole, cross holes and an external groove. The 91 mm length is the full width of the rod eye.
• Measure Before Ordering: 9R-0139 shares this same 55.4 mm bore and fits every machine on this list, but it is only 38 mm long and sits on the swing tower side of the joint. This one is 91 mm.
• Quantity: One per machine - these backhoes carry a single boom cylinder. Sold individually.
• Interchange Numbers: Mates Caterpillar boom cylinder rod pin 209-6850
• Side Fitment: No left or right hand version - one part covers the joint
• Serial Number Notes: Confirm your data plate prefix. The 415 IL and 415F2 IL are separate machines from the 415 and 415F2 and are not covered.
• Material: Steel, low alloy, hardened
• Condition: Aftermarket replacement part
• Shipping Restrictions: Ships within the lower 48 United States only

Common Use Case or Symptoms:

Use when the boom cylinder rod eye has play at the swing tower pin, when the boom drifts sideways at full extension, or when the grease fitting at the rod end will not build pressure. A rod eye that wears oval cannot be bushed a second time - it has to be welded up and bored.

Why Choose Broken Tractor?

• ✅ Rod End Goes To The Swing Tower: On these machines the boom cylinder rod pins to the swing tower and the base pins to the boom. This is the rod eye sleeve, and the page says so instead of leaving you to guess.
• ✅ Ninety One Millimetres Of Bearing: The full width rod eye sleeve, not the 38 mm swing tower bushing that shares its bore and fits the same machines - length is the whole difference.
• ✅ Greaseable Not Dry: Grease hole, cross holes and an external groove, so the joint takes grease instead of running the pin dry against hardened steel.
