Key Notes:

• Part Number: 209-6181 (Caterpillar reference 209-6181)
• Weight: 1.20 lbs
• Application: Boom at the swing tower - the bushing in the boom foot where the boom pins into the swing frame. This is the joint the whole backhoe swings on.
• Location: Backhoe end, boom foot. Two bores, one each side.
• Dimensions: 60.22 mm inside diameter, 73.612 mm outside diameter, 50 mm long
• Style/Type: Straight steel sleeve, no grease hole in the bushing - the grease passage runs through the pin
• Quantity: Two required per machine, one each side of the boom foot. Sold individually.
• Interchange Numbers: Mates Caterpillar swing frame pin 237-5330. Serves the same joint as 237-2252 on the older D Series machines.
• Serial Number Notes: Confirm the prefix on your machine data plate against the list above before ordering - the 430 and the 442E and 444E take a different bushing.
• 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 boom shows side to side play at the swing tower, when the pin turns in the bore instead of inside the bushing, or when grease will not hold at the joint. Left alone, a worn bushing here lets the pin egg-shape the boom foot, and a bushing job becomes a line-boring job.

Why Choose Broken Tractor?

• ✅ The Joint The Backhoe Swings On: Boom foot at the swing tower carries every load the hoe puts down, and it is the first pivot to knock when the grease schedule slips.
• ✅ Same Position As Our D Series Part: The E, F and current machine version of 237-2252, which we already stock - same bore, same pin family, 50 mm instead of 65 mm.
• ✅ Fifteen Models Listed By Data Plate Prefix: Every covered machine shown with its serial prefix, and the 430 exclusion spelled out on the page instead of discovered on arrival.
