Frequently Asked Questions

What is the difference between rubber street pads and metal cleat pads for a Case 590 Super M?

Rubber street pads protect pavement and are better for working on finished surfaces, while metal cleat pads dig into soft, loose, or icy ground for grip. Broken Tractor carries both styles for the 590 Turbo, 590 Super L, and 590 Super M, including single rubber pads, flip-over rubber pads, and metal cleat pads. Choose the pad type based on the ground conditions you work on most.

How do I choose the right stabilizer pin snap ring for a Case 590 Super L?

Match the snap ring to the pin diameter you are servicing. Broken Tractor carries snap rings for 1-1/2 inch pins, 1-3/4 inch pins, and 2 inch pins, plus an external snap ring for 80mm pins on 590SL and 590SM machines. Measure your pin or match the part number to be sure you get the correct fit.

Do you have a replacement stabilizer leg for a Case 590 Super M backhoe?

Yes, Broken Tractor offers a stabilizer leg that fits the 590 Super L and 590 Super M (SKU 192111A1-U). We also carry the leg bushings, leg-to-frame pins, and plate-to-leg pins needed to rebuild the outrigger assembly. Confirm your model when ordering so the leg and hardware match your machine.

What parts do I need to rebuild the stabilizer cylinder on a Case 590 Super L?

Broken Tractor carries outrigger stabilizer cylinders and a stabilizer cylinder rod (SKU 177261A1) for the 590 Turbo, 590 Super L, and 590 Super M, along with the stabilizer and blade cylinder pins that mount them. Fitment can depend on serial number, for example the 580 Super M+ cylinder is split by serial break, so match the part number or confirm with the parts team before ordering.

Which stabilizer pad pins fit the flip-over plate on a Case 590 Super L?

Broken Tractor carries the pin for flip-over stabilizer plate to leg (SKU D149033) and the plate-to-leg pin for single rubber pad setups (SKU D39256), both fitting the 590 Turbo and 590 Super L. There is also a stabilizer plate to leg pin for metal cleat pads (SKU D28648) fitting the 590 series. Pick the pin that matches your pad style and confirm the part number if you are unsure.
