INJECTION PUMP (68.6KW, DELPHI) SUITABLE FOR JCB 3CX, 4CX (DIESELMAX) - 320/06929

Technical Specification and Compatibility

A key component of the fuel system – this is an original (OEM) Delphi injection pump with a power rating of 68.6 kW. It is designed for JCB 3CX and 4CX machines equipped with JCB Dieselmax engines (manufactured after 2005). This is a precision distributor (rotary) pump responsible for metering and delivering fuel under high pressure directly to the injectors, ensuring optimal combustion, performance, and engine operation.

Part number: 320/06929
Alternative part numbers: 320/06738
Manufacturer: GX-OEM (Original Manufacturer: Delphi)
Engine Power: 68.6 kW
Pump Type: Distributor (Rotary)
Compatible Engines: JCB Dieselmax

By choosing GX-OEM parts, you choose uncompromised original equipment quality. Our products are manufactured with the highest precision, guaranteeing a perfect fit and parameters identical to the original. This is the best investment in the long and trouble-free operation of your machine.

Essential for Service

  • › REDX Fuel Filters: You must replace all fuel filters (primary and secondary) to protect the new pump.
  • › Gasket/O-ring: Ensure a 100% seal at the connection to the engine block.
  • › Clean Diesel Fuel: For priming the new pump and filters before startup.

Application in machines

Brand Type / Series / Model
JCB Backhoe Loaders: 3CX, 4CX (with 68.6 kW Dieselmax engine, post 2005)

The list above is for reference. It is crucial to match the part number and engine power rating (68.6 kW).

⚠️ Critical Installation Warning!

The injection pump is the most precise component in the engine. It is extremely sensitive to contamination and water. Installation must be performed in sterile conditions. Before installation, you must replace all fuel filters and check the cleanliness of the entire fuel system. Incorrect installation (e.g., wrong injection timing) or contamination will lead to immediate pump seizure and void the warranty.

Part's Role in the Machine and Failure Diagnostics

The injection pump is the "heart" of the fuel system. It is responsible for precisely metering and compressing fuel to the pressure required by the injectors at the correct moment in the engine's cycle. Its failure will immobilize the machine or drastically reduce its power.

  • › Engine will not start or is extremely hard to start.
  • › Rough running, engine "knocking" or "hunting".
  • › Drastic loss of power, stalling under load.
  • › Excessive smoke (white or black) from the exhaust.
  • › Fuel leaks from the pump housing.

🔧 How a Distributor Pump Works

Rotary (distributor) pumps, like this Delphi model, replaced older in-line pumps due to their higher precision. They work using several key components:

  • Feed Pump: An integrated pump that generates initial fuel pressure.
  • Rotor with Pistons: Fuel from the feed pump enters the rotor, where it pushes two opposing pistons outward.
  • Cam Ring: The outer ends of the pistons ride on a stationary, internal cam ring. As the rotor spins, the cam lobes force the pistons rapidly inward, compressing the fuel to high pressure.
  • Fuel Metering: The fuel dose is precisely controlled by throttling the inlet port that feeds the pistons. Less fuel entering the chamber means a shorter piston stroke and a smaller injection charge.

Frequently Asked Questions (FAQ)

1. What is the difference between this pump and a Perkins (AA/AB) pump?

They have a completely different construction, mounting, drive, and fuel control system. They are for different engine blocks. A Perkins pump (e.g., 17/912400) will not fit a Dieselmax engine, and vice versa.

2. Why must I replace fuel filters (e.g., REDX filters)?

Contaminated or water-filled fuel is the #1 cause of injection pump failure. If the old pump failed (e.g., seized), it is 100% certain that metal debris is in the system. Installing a new pump without flushing the system and replacing all filters will destroy the new pump immediately and void the warranty.

3. What does 68.6 kW mean?

It means this pump is calibrated to work in a JCB Dieselmax engine with a 68.6 kW (approx. 92 HP) power rating. Pumps for different power ratings (e.g., 74.2 kW) have different part numbers and fuel delivery settings.
