Product Description

The TANDEM 33/22 hydraulic pump is a critical component of the working hydraulic system in JCB 3CX backhoe loaders. This aftermarket two-section gear pump provides flow rates of 33 cc/rev + 22 cc/rev and generates the pressure and hydraulic flow required to operate both the front loader and the rear digging arm.

Robust construction and standard SAE/BSPP connections ensure reliable operation in demanding work conditions.

Technical Specifications

  • Flow – Section 1: 33 cc/rev
    (approx. 33 L/min at 1000 RPM)

  • Flow – Section 2: 22 cc/rev
    (approx. 22 L/min at 1000 RPM)

  • Rotation Direction: Left (CCW – counterclockwise, viewed from the shaft end)

  • Shaft: 1.125” (28.8 mm), parallel key

  • Mounting Flange: SAE B, 2 holes

  • Suction Port: Common, 2” SAE flange

  • Pressure Port – Front Section: 3/4" BSPP

  • Pressure Port – Rear Section: 5/8" BSPP

Function and Failure Diagnostics

The hydraulic pump is the heart of the hydraulic system, converting engine mechanical power into hydraulic pressure that drives all actuators and machine functions. Pump failure results in partial or complete immobilization of the backhoe loader.

Typical signs of wear or damage:

  • Loud pump operation (whining, grinding) – indicates cavitation or bearing wear.

  • Very slow hydraulic function despite high engine RPM.

  • Loss of lifting power – the machine cannot lift the load or “struggles” under load.

  • Rapid overheating of hydraulic oil.
