Isuzu 6UZ1 High-Quality Remanufactured Engine

The Isuzu 6UZ1 is an inline six-cylinder, water-cooled four-stroke turbocharged & intercooled diesel engine, adopting OHC 24-valve layout and high-pressure common rail fuel injection system. Widely fitted on Isuzu GIGA heavy trucks, large excavators and engineering equipment.

Our high-quality remanufactured 6UZ1 engine undergoes complete disassembly, component inspection, precision machining and assembly in strict accordance with OEM technical specifications. All key wearing parts including piston, piston ring, bearing, valve, oil seal and gasket are replaced with new spare parts. After assembly, each engine passes bench hot test to verify compression pressure, oil pressure, temperature and power performance. Multiple calibration versions support Euro III/Euro V emission standards, matched with corresponding exhaust after-treatment systems. Suitable for long-distance transportation, heavy-load haulage and continuous operation of construction machinery.

Product Advantages

Powerful Heavy-load Dynamic Performance

• Rated power 257-279 kW @ 1950-2000 rpm, peak torque 1422-1435 N·m @1400-1500 rpm. Wide low-speed torque plateau delivers excellent climbing and overload capability.
• High-pressure common rail fuel system realizes precise injection control, balancing power output and fuel economy.
• Complete electronic diagnosis system, convenient for routine inspection and fault maintenance.

Standardized Remanufacturing & Reliable Quality

• Full disassembly inspection, cylinder block and cylinder head precision rework to restore factory dimensional tolerance.
• Mandatory replacement of all vulnerable components, each unit finished with bench hot running test before delivery.
• Cost advantage compared with brand-new engine, shorter delivery cycle for overseas replacement orders.

Broad Equipment Compatibility

• Standard installation interfaces match Isuzu GIGA heavy truck chassis and multiple large construction machinery.
• Compatible with different transmission assemblies and after-treatment configurations for various emission regions.
• Stable operation under plateau, high temperature and long-time heavy-duty working environments.
