Genuine Parker main hydraulic pump, the heart of the hydraulic system in JCB 3CX and 4CX backhoe loaders. This is a tandem (dual-section) gear pump with a displacement of 41cc/rev (41 L/min per 1000 rpm) for the main working hydraulics (loader, backhoe) and 26cc/rev (26 L/min per 1000 rpm) for the secondary section (e.g., servo control). It provides the precise and reliable operation required in machines with Precision Control (servo joysticks).
PARKER Hannifin is a global leader in motion and control technologies, supplying components for original equipment (OEM) to leading machine manufacturers, including JCB. By choosing a PARKER pump, you are receiving a product identical in quality and specification to the one your machine left the factory with.

The list above is for reference. This pump is dedicated to models with Precision Control (PC), produced from serial number M953913.
Before removing the pump, ensure all pressure in the hydraulic system is fully released (e.g., by lowering attachments and moving joysticks with the engine off). Hydraulic oil under pressure can pierce the skin. The pump weighs 26 kg – use appropriate lifting equipment for installation.
The hydraulic pump is the heart of the machine, converting the engine's mechanical power into hydraulic oil pressure. Its failure immobilizes the entire machine. The most common cause of failure is contaminated oil or running "dry" (cavitation).

It is a dual-section pump (two pumps in one housing, driven by a single shaft). The 41cc section (higher flow) supplies the main working hydraulics (backhoe arm, loader bucket). The 26cc section (lower flow) supplies the steering system and, in machines with Precision Control, the servo control circuit (joysticks).
2. Why must I change the oil and filters when replacing the pump?Failure of the old pump almost always means that metal particles have entered the hydraulic system. Leaving the old oil and filters will cause these particles to be immediately sucked into the new pump, destroying it within minutes or hours. Replacing filters (e.g., **REDX filters**) and oil (e.g., **HYPTRON oil**) is absolutely crucial for the longevity of the new pump and is a condition of the warranty.
3. What is "Precision Control" (Servo)?Precision Control (PC) is a system for controlling the hydraulics using joysticks (servo control), as opposed to the older system of mechanical control via long levers. PC joysticks require a constant, low-pressure pilot supply, which is provided by the smaller section of this tandem pump.
