Stage V engines ready for JCB mid-range machines

JCB has introduced a compact 3.0-litre EU Stage V diesel engine to its mid-range machines. The four-cylinder DieselMAX engine, is 24% smaller and 30% lighter than JCB’s own 4.4-litre EcoMAX powerplant, yet offers 10% higher torque output, with a real world 5% fuel saving. The engine uses innovative particulate and NOx control technologies, that combine the diesel particulate filter (DPF) and diesel oxidation filter (DOC) in a single unit. The engines feature autostop technology for further emissions reduction.


The 3.0-litre engine delivers 55kW (74hp) with a class-leading 440Nm of torque at just 1,150rpm, 10% higher than the larger 4.4-litre EcoMAX. The compact engine produces 5% less CO2 while benefitting from a 5% fuel consumption improvement. Service and maintenance costs have also been cut by 30%, thanks to 500-hour service intervals, hydraulic lash adjusters in the valve train and a sealed-for-life crank case ventilation module, eliminating filter replacement.

The engine is equipped with four glow plugs, for easier cold weather starting, reducing cranking time. The engine is fully integrated with JCB’s LiveLink telematics system, providing vital operating information in real-time for customers and dealers. JCB dealers will also provide a manufacturer-backed DPF/DOC refurbishment program and be able to deliver a de-emissionisation strategy for used equipment exports to non-emissionised territories.

The compact dimensions of the down-sized 3.0-litre engine, have allowed JCB’s engineers to install the engine and exhaust after-treatment within existing engine canopies to maintain market-leading visibility.

The 3.0-litre Stage V engine will be offered on the 531, 535 and 540 Loadall models, 3CX backhoe loaders, large platform skid steer and compact track loaders, 6T to 9T site dumpers, RTFLs and 13 tonne excavators.
