Refurbished/Reconditioned Howo 6x4 10-Wheel Dump Truck

1. Engine System (Mainstream WD615 model; 371HP or 375HP options available)
Complete engine disassembly and overhaul: inspection of cylinder liners, pistons, and piston rings, with full replacement of all wear parts; calibration of fuel injectors and fuel injection pumps to eliminate issues such as black smoke, power loss, excessive oil consumption, and crankcase blow-by.
Replacement of all filter elements (engine oil, diesel, oil-water separator, and air filters); cleaning of the radiator and cooling channels; replacement of aged hoses and gaskets to ensure stable heat dissipation under high-temperature conditions. Filling with fresh engine oil and coolant, followed by extended bench testing to monitor temperature and oil pressure.
2. Drivetrain and Axle System
HW19710 manual transmission (10 forward gears + 2 reverse gears): disassembly and inspection of gears, bearings, and friction discs; replacement of out-of-tolerance parts and removal of sludge; transmission fluid change; ensuring smooth gear shifting without jerking, slipping, or abnormal noise.
Inspection and servicing of dual HC16 heavy-duty rear axles: checking differentials and axle shaft gears; replacing oil seals and bearings; servicing wheel-end reducers; replacing brake pads and brake shoes. Comprehensive inspection of the pneumatic system: replacing aged air lines and air reservoirs; ensuring the dual-circuit air braking system is responsive and reliable.

Refurbished Howo 10-wheel dump truckCargo Box (Large Body)
Constructed from highly wear-resistant manganese steel (8mm floor plate, 6mm side plates); robust and impact-resistant, suitable for hauling ore, crushed stone, and debris.
Standard external dimensions: 5600/5800mm × 2300mm × 1500mm; customizable dimensions available (extended length, increased height, thicker steel).
Structure: Integrated welded body reinforced with stiffeners; corners feature thickened, wear-resistant protective plating.
Refurbishment process: Comprehensive flaw detection upon arrival; cracks reinforced via full-seam welding using high-strength construction machinery electrodes; severely worn floor plates, side walls, and teeth replaced with new steel plating.
Optional upgrades:
 Floor plate thickened to 14mm (for heavy-duty mining operations)
Wear-resistant liner plates
Tailgate with automatic safety locking mechanism
Body height/length adjustment to suit specific load requirements or container loading
The cargo box can be refurbished to specifications or replaced entirely with a brand-new manganese steel unit.

Cab (HW76 Widened Single-Bunk Cab)
The classic HW76 extended single-bunk cab features a four-point floating suspension system that absorbs shocks from rough terrain and long-distance hauling, thereby reducing driver fatigue. The spacious interior includes seats for the driver and co-driver plus a rear single bunk, making it ideal for long shifts at work sites.
Equipment: Hydraulically assisted adjustable steering wheel, multi-speed wipers, high-capacity A/C, and heating system; the instrument cluster is fully functional with clear readouts and comprehensive fault alerts.
Refurbishment Process:
1. Exterior inspection: Sheet metal repair for dents and deformations; rust removal and treatment.
2. Interior deep cleaning: Replacement of damaged seat upholstery and bunk cushions.
3. Door and window overhaul: Replacement of seals and weatherstripping to eliminate water and air leaks.
4. Component check: Inspection of lights, horn, reversing buzzer, and mirrors; replacement of any broken mirror glass.
5. Electrical system check: Inspection of the entire wiring harness; replacement of aged wiring, waterproofing of connectors, and clearing of dashboard fault codes.
Optional Upgrades:
 Brand-new seat upholstery
 Widened side mirrors and additional protective mirrors
 Cab repainting (Red / Blue / Yellow)
 Conversion to LHD (Left-Hand Drive) or RHD (Right-Hand Drive) to meet specific national regulations
The cab features a robust structure and excellent visibility. It is highly regarded in African mining and long-distance earthmoving markets, with readily available spare parts and easy maintenance.

Used Howo 6x4 Dump TruckWD615 Engine
The Sinotruk WD615 series is a classic inline-six, water-cooled, turbocharged diesel engine. Available in 371HP and 375HP variants and compliant with Euro II/III emission standards, it is the most widely used engine model for mining dump trucks in Africa and Central Asia. It delivers abundant torque and strong heavy-load climbing capability, while demonstrating excellent fuel adaptability-handling the variable quality of local diesel supplies effectively.
Overhaul Process:
1. Complete engine disassembly; flaw detection on the cylinder block and head; measurement of wear on cylinder liners, pistons, and crankshafts, with replacement of all parts exceeding tolerance limits.
2. Replacement of the full overhaul kit: piston rings, cylinder liners, connecting rod and main bearings, valves, valve stem seals, and cylinder head gaskets.
3. Professional calibration of fuel injectors and high-pressure fuel pumps to rectify issues such as poor atomization, insufficient power, and black exhaust smoke.
4. Replacement of all filter elements: engine oil, fuel, oil-water separator, and air filters.
5. Cooling system cleaning; inspection and servicing of the water pump and thermostat; replacement of aged hoses and gaskets to prevent overheating.
6. Post-assembly bench testing: verification of oil pressure, coolant temperature, and power output; units are cleared for release only if free of abnormal noises, oil leaks, or air leaks.
Advantages: Mature and simple design, abundant global spare parts availability, and low maintenance complexity; parts and service are easily accessible across Africa.
Optional: Brand-new engine assembly replacement available upon request.
