JCB 3CX Backhoe Loader Overview
The JCB 3CX is one of the most iconic backhoe loaders in the world, introduced in the 1980s and continuously refined over decades. By 2006, the 3CX had evolved into a highly versatile machine equipped with servo controls, a turbocharged diesel engine producing around 92 horsepower, and a hydraulic system capable of supporting a wide range of attachments. With a dig depth of over 14 feet and a loader bucket capacity of 1.0 cubic yard, the 3CX became a staple in construction, agriculture, and utility sectors.
JCB (Joseph Cyril Bamford Excavators Ltd.), founded in 1945 in the UK, has sold hundreds of thousands of 3CX units globally. The machine’s modular design and robust support network have made it a favorite among contractors and municipalities alike.
Challenges in Sourcing a Hammer Line Kit
Owners seeking to retrofit their 3CX with a hydraulic breaker (commonly known as a hammer) often face difficulties sourcing the OEM hammer line kit. The kit, typically priced around £1,500, includes a hydraulic valve, hoses, couplings, electrical wiring, and mounting hardware. However, due to fluctuating inventory and regional supply chain issues, dealers may not always have the kit in stock or be able to provide a reliable delivery timeline.
The specific kit number referenced for the 2006 model with servo controls is 980/89947. Unfortunately, this part has been reported as difficult to obtain, even after contacting multiple suppliers across the UK and abroad.
Alternative Solutions for Hydraulic Breaker Installation
Given the scarcity and cost of the OEM kit, many operators explore custom plumbing solutions. A skilled hydraulic technician can fabricate a breaker circuit using off-the-shelf components, often at a fraction of the OEM price. Key steps include:
While the OEM kit offers plug-and-play convenience and factory-grade integration, it may not justify the cost or wait time for some users. A custom installation using quality components can often be completed for £300–£600, depending on labor and parts availability. The trade-off is the need for technical expertise and potential deviation from factory specifications.
Anecdote from the Field
In Alberta, a technician who previously worked at a JCB dealership recalled installing several hammer kits on 3CX units. He noted that JCB frequently changed hydraulic layouts between model years, making it difficult to standardize installations. In one case, a customer opted for a custom-built system using a third-party valve and Parker hoses. The system performed flawlessly for years and cost less than half the OEM kit price.
Recommendations for Owners
Retrofitting a JCB 3CX with a hydraulic breaker line is entirely feasible, even without the OEM kit. While sourcing the factory kit may be ideal, a custom solution offers flexibility, cost savings, and immediate availability. With proper planning and professional installation, the 3CX can be transformed into a powerful demolition and trenching tool, extending its utility across a broader range of tasks.

Alternative Solutions for Hydraulic Breaker Installation
Given the scarcity and cost of the OEM kit, many operators explore custom plumbing solutions. A skilled hydraulic technician can fabricate a breaker circuit using off-the-shelf components, often at a fraction of the OEM price. Key steps include:
- Installing a Hammer Valve: A two-way solenoid valve is required to control flow to the breaker. This valve can be mounted externally and wired to a switch in the cab.
- Routing Flow and Return Lines: High-pressure hoses must be routed from the valve to the dipper arm, with proper clamping and protection against abrasion.
- Return-to-Tank Line: Ensure the return line bypasses the main valve block and flows directly to the hydraulic tank to prevent backpressure.
- Electrical Integration: A switch or button must be added to the servo joystick or dashboard to activate the solenoid valve.
- Hammer Line Kit: A hydraulic circuit designed to power a hydraulic breaker attachment.
- Servo Controls: Electronically assisted joystick controls that actuate hydraulic valves via pilot pressure or electric signals.
- Return-to-Tank (RTT): A hydraulic return path that routes oil directly to the reservoir, minimizing resistance and heat.

Recommendations for Owners
- Consult a Hydraulic Specialist: A knowledgeable technician can design a safe and effective breaker circuit tailored to your machine.
- Use Quality Components: Invest in high-pressure-rated hoses, valves, and couplings to ensure durability.
- Document the Installation: Keep a wiring and plumbing diagram for future maintenance or resale.
- Test Flow and Pressure: Verify that the breaker receives adequate flow (typically 30–60 L/min) and pressure (up to 200 bar) for optimal performance.
