Product Description
D80083 Hydraulic Pump — Replacement hydraulic pump designed for Case construction and industrial equipment that require steady hydraulic flow and dependable system pressure. This pump is commonly used to restore proper operation to loader, backhoe, and steering hydraulic systems on compatible machines.
D80083 is frequently associated with Case loader backhoe models such as the 480, 480B, 480C, 530, and select 580 series machines, depending on configuration. It is intended for applications where consistent hydraulic performance is essential for digging, lifting, and material handling tasks.
Common symptoms of a failing hydraulic pump include:
- Slow or weak loader and backhoe response
- Loss of hydraulic power under load
- Pressure fade as hydraulic oil temperature increases
- Excessive noise or vibration from the pump area
- Inconsistent or jerky hydraulic operation

Fitment and installation guidance: Always compare the replacement pump to the original unit removed from your machine. Verify shaft or spline type, mounting bolt pattern, rotation direction, and hydraulic port orientation. Proper identification before installation helps prevent downtime and incorrect fitment.
Recommended system preparation: Inspect suction and return hoses for air leaks or restrictions, replace hydraulic filters, and flush contaminated hydraulic oil if necessary. Proper system maintenance is critical to achieving maximum service life from a new hydraulic pump.
Need help confirming compatibility? Provide your machine model, serial number, and any identification markings from the existing pump so the correct replacement can be verified before ordering.
