222-0103 Hydraulic Axial Piston Pump — Cat 320B

This is a Hydraulic Axial Piston Pump, a high-performance component vital for generating pressurized hydraulic fluid to power machine functions. Built to meet stringent OEM quality and performance standards, it ensures reliable operation and durability comparable to a new factory unit. Operators may experience slow or erratic hydraulic movements, loss of system pressure, or increased operating temperatures if this pump begins to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

An initial symptom of a failing axial piston pump is a noticeable reduction in the speed and power of hydraulic operations. If ignored, the pump's efficiency will continue to decline, leading to slower cycle times, increased fuel consumption, and potential overheating of the hydraulic fluid. The ultimate consequence is a significant loss of machine productivity and potential damage to other hydraulic components.

Installation Tip

Ensure the hydraulic reservoir is filled to the correct level with the specified fluid before starting the pump. Avoid running the pump dry, as this can cause immediate internal damage.

Service Note

Replace the hydraulic filter element and inspect the hydraulic fluid for contamination or signs of wear when installing a new axial piston pump.
