Overview – PUMP PRESSURE SENSOR A040A034
Engineered for Cummins hydraulic positions as the pressure sensor reading line pressure at the pump, the Cummins PUMP PRESSURE SENSOR A040A034 meets the tolerances your equipment was designed around.
Parts Characteristics
A pressure sensor that reads the live hydraulic pressure and reports it to the controller, so the system protects itself from over-pressure and the operator sees the real number. It carries the signal that keeps the strategy honest, so a true, responsive sensor keeps the circuit in its window.
Applicable Models & Applications
Used at Cummins hydraulic positions specifying this pump pressure sensor. Match the thread, the connector and the calibration against your old sensor – pressure sensors differ in how they read and plug.
Maintenance & Replacement
Inspect the connector for corrosion and the port for weep at every hydraulic service. A sensor that has begun to oxidise reads pressure wrong, and the fault creeps in before it trips a code.
Confirm the reading tracks the gauge and the relief behaviour. A sensor that sits at a fixed value hides an over-pressure from the rest of the system.
Replace rather than clean a sluggish one. A sensor that has lost its calibration cannot be restored, only swapped.
Keep the correct pump pressure sensor for your circuit on the shelf. It is cheap, it protects an expensive pump, and it is exactly the part missing when a pressure reads wrong today.
Price Reference (USD)
As a reference, the PUMP PRESSURE SENSOR A040A034 is typically priced between USD 15 and USD 90 depending on configuration, lot size, and current exchange rates.
Value & Service
We supply brand-new Cummins pump pressure sensors with the thread and calibration confirmed against your hydraulic system, so the pressure reading stays honest.
With Racer Machinery, the PUMP PRESSURE SENSOR A040A034 comes with fitment confidence and a warranty you can actually use, not a grey-market guess.
