Main Hydraulic Pump (41/26CCR) suitable for JCB - 20/911200

Technical Specification and Compatibility

An essential main hydraulic gear pump (tandem) 20/911200 by PARKER. This is the heart of the hydraulic system in JCB 3CX and 4CX backhoe loaders. The 41/26CCR model is a dual-section pump, with the front section having a displacement of 41 cc/rev and the rear section 26 cc/rev. It features a 1” parallel keyed shaft, a 2-bolt SAE B mounting flange, and counter-clockwise rotation (when viewed from the shaft end).

Required for Installation and Warranty

To ensure the longevity of the new pump and maintain warranty conditions, it is absolutely mandatory to flush the entire hydraulic system and replace the oil and filters. Contaminants (metal filings) from the old pump will immediately destroy the new component. We strongly recommend:

  • REDX hydraulic filters – for effective filtration of debris.
  • HYPTRON hydraulic oils – with the correct cleanliness class for new pumps.

⚠️ Safety Warning

Failure of the main hydraulic pump means a total loss of working arm functionality and potentially power steering. A failed pump can rapidly contaminate the ENTIRE hydraulic system (including the orbitrol and cylinders) with metal filings, making repair impossible and multiplying costs.

Part Role in the Machine and Failure Diagnostics

The 20/911200 main hydraulic pump draws hydraulic oil from the tank and compresses it to high pressure (up to 275 bar). It then sends it to the valve blocks, which direct the oil to the cylinders, powering the front loader and rear backhoe arm. As a tandem pump (dual-section 41+26cc/rev), it feeds two separate circuits or combines the flow for increased performance.

  • › Total loss of hydraulics or very slow operation of all cylinders.
  • › Characteristic "whining" or loud noise from the pump, worsening under load.
  • › Machine loses power ("fades") after the oil warms up (internal bypassing).
  • › Foaming oil in the hydraulic tank or overheating.
  • › Finding metal filings in the hydraulic filter or oil.

🔧 Expert Guide: Key Installation Tips

  1. Replace Oil and Filters: You must replace the hydraulic oil (we recommend HYPTRON Hydraulic Oils) and all hydraulic filters (we recommend REDX Hydraulic Filters). This is a warranty condition.
  2. Flush the System: The entire hydraulic system (tank, hoses, cylinders, cooler) must be professionally flushed to remove all metal debris from the old pump.
  3. Clean Installation: Ensure sterile conditions when connecting hydraulic lines. Any contamination (sand, dust) is lethal to pumps.
  4. Prime the Pump: Before the first start-up, fill the pump housing and the suction (inlet) line with clean hydraulic oil to prevent a dry start.
  5. First Start-up: Run the engine at low idle for several minutes without operating the hydraulics to allow the pump to bleed itself.

Frequently Asked Questions (FAQ)

What does 41/26CCR mean?

This is the designation for a tandem (dual-section) pump. It means the first (front) section has a displacement of 41 cc/revolution, and the second (rear) section has 26 cc/revolution. CCR stands for Counter-Clockwise Rotation.

How do I check the rotation direction?

The direction of rotation (in this case, CCW - Counter-Clockwise) is always determined by looking at the pump from the shaft end.

Why must I replace filters and oil when changing the pump?

The failure of an old hydraulic pump almost always releases millions of tiny metal particles into the system. Leaving the old oil and filters will cause this debris to be sucked into the new pump, destroying it within minutes or hours. This is the main reason for warranty rejection on hydraulic pumps.
