Engine Assembly for Sinotruk HOWO 336HP 371HP Dump Truck WD615 Series Spare Parts
Core Power Parameters
The WD615 series is one of the main power sources for Sinotruk HOWO dump trucks, with 336HP and 371HP corresponding to different specific models and calibrations.
336HP Version (e.g., WD615.69)
-
Max Power: 247 kW (336 HP) @ 2200 rpm
-
Max Torque: 1350 Nm @ 1100–1600 rpm
-
Fuel Consumption Rate: approx. 195 g/kWh
371HP Version (e.g., WD615.47)
-
Max Power: 273 kW (371 HP) @ 2200 rpm
-
Max Torque: 1500 Nm @ 1100–1600 rpm
Structural Features and Performance
-
Mature base platform: The WD615 series is a 6-cylinder in-line, water-cooled, four-stroke direct-injection diesel engine with a displacement of 9.726 L and a bore × stroke of 126×130 mm. This series is widely used in Sinotruk vehicles, with mature technology and a relatively well-established parts supply and repair system.
-
Torque reserve and dump-truck application suitability: Maximum torque is continuously delivered over a broad speed range of 1100–1600 rpm. This characteristic suits the low-speed, high-torque requirements of dump trucks during heavy-load starting, hill climbing, and driving on unpaved roads.
-
Turbocharging and intercooling: The engine adopts turbocharging and intercooling technology, which helps increase intake air density and combustion efficiency while controlling thermal load while meeting power output requirements.
-
Emission standards: The 336HP and 371HP WD615 models (such as WD615.69 and WD615.47) are marked as Euro II emission standards in most export vehicle documentation. Note that actual configurations in the domestic market may differ depending on the year and regulatory requirements.
Notes
The WD615 series is a large engine family, and different suffix models (such as .69 and .47) differ in power, torque, and emission calibration. The above parameters come mainly from Sinotruk export vehicle documentation and official parameter tables. For a specific dump truck, the engine model on the actual vehicle nameplate should be taken as authoritative. In addition, the oil specifications for WD615 engines differ from those of the newer MC series, and the two should not be mixed during maintenance.

Introduction
This remanufactured WD615.47 engine assembly is a high-performance replacement power unit specially developed for Sinotruk HOWO 336HP and 371HP dump trucks, semi-trailer tractors and mixer trucks.
The whole engine undergoes complete disassembly, deep cleaning, defect inspection and standardized remanufacturing processing. All worn core parts including cylinder liners, pistons, crankshaft, connecting rods, bearings and valve assemblies are replaced with brand-new standard OEM spare parts, which fully restores the original power parameters of WD615 series engine. Adopting mature fuel injection matching technology, this engine features strong torque output, stable combustion, low fuel consumption and low black smoke emission, and can maintain reliable operation under long-time heavy-load mining, construction and long-distance highway transportation conditions.
Each engine assembly completes strict bench running-in test, power detection and sealing inspection before delivery to eliminate hidden troubles such as oil leakage, water leakage, abnormal noise and insufficient power. We adopt shockproof export wooden case for single unit packaging to avoid collision damage during cross-border sea, air and land transportation. Multiple payment methods including T/T and PayPal are supported, with diversified global logistics solutions available, perfectly meeting bulk wholesale and after-sales maintenance procurement demands of Sinotruk heavy truck spare parts dealers all over the world.
