Frequently Asked Questions
Which power steering pump fits a Case 580C backhoe?
The Power Steering Pump SKU D84179 fits Case 580C backhoes along with the 480C, 480D, 480LL, 580D, and 580 Super D. Since fitment on these vintage machines can vary by casting and part number, verify by casting and part number before ordering. Our parts team can help confirm the right pump if you are unsure.
Do you have a power steering pump for a Case 430 backhoe?
Yes, Broken Tractor carries the Power Steering Pump SKU A137187, which fits the Case 430CK along with the 480B, 480CK, 580B, and 580CK. We also offer a power steering pump O-ring (A35965) that covers the 430 and 430CK. Match the casting and part number on your existing pump to confirm the correct fit.
How do you tell if a power steering pump is bad on a Case backhoe?
Common signs of a failing power steering pump include noise while steering, hard or heavy steering, and loss of hydraulic pressure in the steering circuit. Since the pump provides hydraulic pressure for the power steering system, weak or inconsistent assist often points to the pump or its seals. Broken Tractor carries complete pumps as well as gaskets and O-rings if only the seals need replacing.
Can I just replace the seals instead of the whole power steering pump?
In some cases yes. Broken Tractor sells the pump gasket (A30042) and power steering pump O-ring (A35965) individually, which can address leaks without buying a complete pump. If the pump itself is worn or noisy internally, a complete replacement pump like A137187 or D84179 is the better option.
Why is my Case backhoe power steering pump making noise?
Power steering pump noise often comes from low fluid, air in the system, or internal wear in the pump. Worn seals or O-rings can also let air into the steering circuit and cause whining. If the pump is worn internally, replacing it is usually the fix, and Broken Tractor offers complete pumps plus gaskets and O-rings to reseal the assembly.
