Frequently Asked Questions

What is the difference between the 1-pin and 2-pin swing tower on a Case 580D or 580 Super E?

The Case 580D, 580E and 580 Super E were built with either a 1-pin or a 2-pin swing tower to boom connection, and the pins and bushings for the two styles are different. Broken Tractor offers a One-Pin Style Swing Tower Pin and Bushing Kit (CS-580D-STK-1) and a Two-Pin Swing Tower Pin and Bushing Kit (CS-580D-STK-2). We also carry individual parts such as the 1-pin style swing tower to boom bushing (D91241) and the 2-pin style lower swing tower to boom pin (D125594). Check which style is on your backhoe, or match the part number on your old pin, before ordering.

Do Case 580C swing tower pins fit a Case 580D?

Not always. The 580B and 580C use a different swing tower pin and bushing setup than the 580D and 580 Super E, so many swing tower parts are model specific. For example, the swing tower to frame pin D74004 fits the 580B, 580C and 580F, while the upper swing tower to frame pivot pin D90727 fits the 580D and 580 Super E. Other parts, such as the boom to dipper pin D45523 and the swing tower bushing D94018, fit all four models, so confirm your model before you order.

What swing tower repair kits are available for a Case 580B or 580C backhoe?

We carry a complete Case 580C Swing Tower Pin and Bushing Rebuild Kit (CS-580C-STK) along with position-specific kits for the 580B and 580C. These include the Swing Tower Boom Pin and Bushing Repair Kit (PVPK1), the Upper Pin Repair Kit (PVPK6), the Lower Repair Kit with pin and bushing (PVPK7), and the Repair Kit at the swing cylinder (PVPK5). The position kits let you repair only the worn joint instead of rebuilding the whole tower.

What size snap rings and washers do Case 580 backhoe boom pins use?

Broken Tractor carries snap rings and washers for both 1-1/2 inch and 1-3/4 inch pins on Case 580B, 580C, 580D and 580 Super E backhoes. Snap rings include the 1-1/2 inch pin snap ring (D25279) and the 1-3/4 inch pin snap ring (103-16175). For washers, we offer 1.5 inch options (U11649 in 10 gauge and 495-81292) and 1.75 inch options (495-81226 and 30575 in 14 gauge). Measure your pin diameter to choose the right size.

What boom to dipper pin fits a Case 580C or 580 Super E?

The boom to dipper pin D45523 fits the Case 580B, 580C, 580D and 580 Super E backhoe. For the 580D and 580 Super E, we also carry the boom to dipper pin nut (181042A1). Related pins in the same area include the boom to dipper cylinder tube end pin (D72359) and the dipper to dipper cylinder rod pin (D52522). If you are unsure which pin your machine needs, call (800) 909-7060 and our parts team can help confirm fitment.
