A key component of the working hydraulics system – a dual-section (tandem) 33/22 gear pump by FEK. Designed for older models of JCB 3CX backhoe loaders. The pump is responsible for generating pressure for the entire system, powering the backhoe arm and the loader. It features a precision-made 1.125" (28.8mm) parallel keyed shaft and has a counter-clockwise (CCW) rotation.

The list above is for reference. We recommend verifying the part number on your old pump's housing and confirming the specifications (shaft, ports, rotation) before purchasing.
Before removing the pump, ensure all pressure in the hydraulic system is fully released (e.g., by lowering attachments and moving controls with the engine off). Hydraulic oil under pressure can pierce the skin. Secure the machine against rolling.
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).

This is a dual-section (tandem) pump. It means two separate pumping mechanisms are in one housing. The first section has a displacement of 33cc/rev, and the second has 22cc/rev. This allows it to power two independent hydraulic circuits (e.g., one for the loader, one for the backhoe) from a single drive.
2. What does "CCW" rotation mean?CCW (Counter-Clockwise) means that when looking at the pump shaft, it rotates to the left (counter-clockwise). Installing a pump with the wrong rotation will destroy it instantly.
3. Why must I change oil (e.g., HYPTRON) and filters (e.g., REDX)?Failure of the old pump almost always means that metal particles (debris) have entered the hydraulic system. Leaving the old oil and filters will cause this debris to be immediately sucked into the new pump, destroying it within minutes or hours. Replacing filters and oil is absolutely critical for the longevity of the new pump and is a condition of the warranty.
