Product Introduction
The 161560040058 complete top cylinder assembly is a heavy-duty cylinder head assembly designed for SINOTRUK HOWO WD615 series diesel engines. The cylinder head is one of the most important engine components, responsible for sealing the combustion chamber, supporting valve train components, and maintaining stable engine compression during operation.
This complete cylinder head assembly typically includes the cylinder head body, intake valves, exhaust valves, valve springs, rocker arm components, and related valve train parts, providing a complete solution for diesel engine overhaul and maintenance applications.
Manufactured using high-strength alloy cast iron materials and precision machining technology, the cylinder head provides excellent resistance to high temperature, combustion pressure, and long-term heavy-duty operation. Similar SINOTRUK HOWO cylinder head assemblies are widely used in HOWO dump trucks, tractor trucks, and construction vehicles.
The cylinder head works together with pistons, cylinder liners, camshaft systems, injectors, and turbocharging systems to maintain stable combustion efficiency, engine power output, and fuel economy under demanding transport conditions.
Its reinforced structure offers strong sealing performance and thermal stability, helping reduce coolant leakage, compression loss, and engine overheating risks. OEM-standard manufacturing ensures accurate installation dimensions and reliable compatibility with original WD615 diesel engine systems.
The 161560040058 complete cylinder head assembly is commonly used in HOWO 371, HOWO 375, and other SINOTRUK heavy-duty truck platforms operating in mining, logistics, and industrial transportation environments.
Each unit undergoes pressure testing, hardness inspection, sealing verification, and dimensional accuracy testing before shipment to ensure dependable engine performance and long service life.
