Product Description
D53690 Case Hydraulic Pump — Restore smooth, reliable hydraulic performance on compatible Case construction and industrial machines. This pump is commonly used as a replacement hydraulic pump for Case loader backhoe and industrial applications where dependable flow and pressure are critical for loader, backhoe, and steering functions.
Common applications (verify your exact model/serial range): This pump is widely listed for Case equipment including models such as the 480C and 580C/580F family, and is often referenced for certain 580B/580C loader backhoe applications depending on configuration. Always confirm fitment by part number and machine details before ordering.

These measurements are frequently published for D53690 interchange pumps; if your existing pump differs, match to your original pump and machine configuration.
Why replace the pump? Weak hydraulics, slow cycle times, inconsistent pressure, whining noise, or overheating can all point to a worn hydraulic pump. Replacing a tired pump can help bring back predictable lift performance and smoother machine operation.
Recommended best practices: Flush contaminated oil, replace filters, and inspect suction/return lines before installing a new pump. Contamination is one of the most common causes of early pump failure.
Need help confirming fitment? If you share your machine model and serial range (or the numbers stamped on your original pump), we can narrow compatibility and reduce the chance of a wrong-order situation.
