Product Description
S516451 Hydraulic Pump In Stock— Replacement hydraulic pump engineered for Case construction and industrial equipment that require dependable oil flow to operate hydraulic functions smoothly and consistently. This pump is commonly selected when restoring proper system response and pressure control.
S516451 is used in hydraulic systems where steady performance is critical for loader, backhoe, and auxiliary operations. A properly functioning pump helps maintain predictable machine behavior, improved control, and reduced operator fatigue during long work cycles.
Hydraulic pump wear often shows up as:
- Delayed or uneven hydraulic movement
- Reduced lifting or digging strength
- Hydraulic functions that weaken after warm-up
- Excessive noise or vibration during operation
- Difficulty holding consistent system pressure

Installation considerations: Prior to installation, compare the new pump to the original component removed from the machine. Confirm shaft or spline design, bolt mounting pattern, rotation direction, and hydraulic port placement to ensure correct alignment and function.
Prepare the hydraulic system: A clean system is essential when installing a replacement pump. Inspect suction lines for air leaks, replace hydraulic filters, and address contaminated oil to help prevent premature pump wear or failure.
Unsure about compatibility? Supplying your machine model, serial number, and any identification markings from the existing pump allows fitment to be verified before ordering.
