Stage V

The Stage V JCB engine is in models 430 and 448. The Stage V 430 delivers 55kW (74hp) with a class-leading 440Nm (325lb-ft) of torque at just 1,150rpm. Stage V 448 delivers 81kW-129kW (109hp-173hp) with maximum torque at 690Nm (509lb-ft) at 1,500rpm.

  • The Stage V models offer increased productivity whilst minimising fuel consumption along with fit-for-life engine after-treatment.
  • Advanced and highly developed combustion and air handling systems allow the most efficient operation whilst producing ultra-low, in-cylinder emissions.
  • An integrated pre-cleaner system and after-treatment induction system with wiring, ensuring an easy to install package.
  • JCB IPUs feature full tropical rated aluminium cooling packages with heavy-duty mounting feet.

Stage IV - Tier 4 - BS IV (56+)

The Stage IV is avaliable in models 444 and 448. The Stage IV 444, 4-cylinder 4.4 litre engine and 448 4-cylinder 4.8 litre engine delivers 68kW-129kW (91hp-173hp) with maximum torque of 690Nm (508lb-ft).

  • When coupled with the DEF tank and integrated dosing module system, the package becomes a “Plug and Play” solution which eliminates a significant element of OEM integration work. This reduces cost and shrinks machine development timescales.
  • Where required the innovative minimal after-treatment solutions provides a compact installation for 56+ kW engines - ensuring a “no compromise” approach to machine design for our customers.
  • Every JCB IPU engine has been engineered for maximum robustness. The IPU's are subjects to thousands of hours of test cell and real-world testing to validate the products.
  • No DPF - No regeneration. No excess heat. Maximum uptime. No interruptions.

Tier 4

The Tier 4 4-cylinder JCB engine is available in models, 430, 444 and 448. Tier 4 430, 4.3 litre engine delivers 55kW (74hp) with maximum torque of 440Nm (325lb-ft). The Tier 4 444, 4.4 litre engine delivers 55kW-93kW (74hp-125hp) with maximum torque of 550Nm (406lb-ft). The Tier 4 448, 4.8 litre engine delivers 108kW-129kW (145-173hp) with maximum torque of 690Nm (509lb-ft) at 1,500rpm.

  • JCB engines provide class leading torque at low engine speeds; allowing OEMs to design more efficient equipment with increased output.
  • Advanced and highly developed combustion and air handling systems allow the most efficient operation whilst producing ultra-low, in-cylinder emissions.
  • Versatile - Identical engine footprint and high degree of component commonality between engine ranges.
  • Reduced Operating Costs - Up to 15% fuel savings, 500 hours standard oil service interval. 

Stage IIIB - Tier 4i - BS IV (UN Equivalent)

The Stage IIIB engine is avaliable in models 444 and 448. The Stage IIIB 444, 4-cylinder 4.4 litre engine and 4-cylinder 4.8 litre engine delivers 68kW-129kW (91hp-173hp) with maximum torque of 690Nm (509lb-ft) at 1,500rpm.

  • Heavy duty 60kW (80hp) and low duty 10kW (13hp) integrated PTO options as standard.
  • Efficient combustion process has led to no after-treatment requirements.
  • Two years unlimited hours warranty.
  • Integrated Wiring Harnesses. 

Stage IIIA - Tier 3 - BS III - CPSB II (UN Equivalent)

Turbocharged Aftercooled 4-cylinder 4.4 litre engine delivers 55kW-120kW (74hp-161hp) with maximum torque of 655Nm (483 lb-ft).

FAQ's

The JCB engine serial number is printed on the engine emission labels, which are positioned at the top of the rocker cover, and on the hot side of the engine block.
Almost any off-highway application can be supported. Our sales and applications team are here to support the selection of the right engine for the right application.
Recommended fluids vary depending on the engine type, environment and application. Consult your JCB engine distributor or JCB machine dealer for more information.
As standard, a JCB Base engine will comprise of an engine with basic ancillaries such as alternator and belt drive, as well as engine aftertreatment (where applicable). IPU is the acronym for Industrial Power Unit. The IPU and G-Drive products include everything that the OEM base engine includes plus a fan, radiator cooling pack, air induction system and associated mounts and brackets. The G-Drive is a generator specification engine with a similar assembly to an IPU.
