Product Description
4HK1 Remanufactured Engine Product Introduction
Product Overview
The 4HK1 remanufactured engine is a high-quality powertrain that is professionally repaired and upgraded based on the original 5.2L inline 4-cylinder turbocharged diesel engine. Through a strict remanufacturing process, the performance is restored to more than 95% of the new engine standard, suitable for light/medium trucks, construction machinery, generator sets and other equipment, providing a cost-effective alternative.
Core Advantages
Original-level remanufacturing standards
Using ISO 9001 certified processes, core components (cylinder block, crankshaft, turbine) are repaired according to technical specifications.
Key accessories use original/OEM equivalent parts (such as injectors, piston rings, bearings).
Performance and reliability
Power restored to 190-240 HP, torque 500-600 Nm (depending on the tuning version).
Optimized fuel injection system, fuel consumption is reduced by 10-15% compared to second-hand old engines.
Warranty and service
12 months or 100,000 km core component warranty (cylinder block, crankshaft, turbine).
Provide technical support and installation guidance (applicable models: ISUZ U ELF, FVR trucks, etc.).
Environmental compliance
Meet the National IV/Euro IV emission standards by default, and optionally upgrade DPF (particulate filter) or SCR (urea injection) to the National V/Euro V standards.
Remanufacturing process
Steps Operation content
Disassembly and cleaning Completely disassemble the engine, ultrasonic cleaning to remove carbon deposits and sludge, and detect part wear.
Precision inspection Three-dimensional measurement of cylinder block/crankshaft deformation, magnetic particle inspection for cracks, and scrapping of unrepairable parts.
Core repair Cylinder boring and shaft grinding, replacement of piston rings/bearings, repair of turbochargers (or replacement).
Assembly test Assemble according to the original torque standard, bench test for more than 2 hours, and verify power, fuel consumption, and emission data.
Surface treatment Spray the original color and mark the remanufacturing number (support traceability).
Optional configuration
Basic version: restore to the original standard performance (recommended for general use).
High performance version:
Enhanced turbocharging (peak torque increased by 10%).
Upgraded low friction piston ring (reduced fuel consumption).
Special adaptation:
Generator set PTO interface.
Construction machinery hydraulic pump drive flange.
Typical adaptation models
Trucks: ISUZ U ELF N series, FVR, FVZ
Construction machinery: excavators (such as ZX120), forklifts
Generator sets: 100-150kW diesel generators
