The OEM Exhaust Manifold 1006867720 is a precision-engineered exhaust system component manufactured exclusively for the Shacman X5000 heavy-duty diesel engine. This critical manifold collects the extremely hot, high-pressure exhaust gases from each cylinder’s exhaust port and channels them efficiently into a single outlet that directs the combined gas stream to the turbocharger turbine inlet, where the exhaust energy is harnessed to drive forced induction and boost engine power output.
Cast from high-silicon molybdenum ductile iron or fabricated from high-grade stainless steel, the exhaust manifold delivers exceptional resistance to thermal fatigue, cracking, and warping under the extreme cyclic temperature conditions that range from sub-zero cold starts to sustained full-load operation where the manifold can glow visibly red. The 1006867720 part features smoothly contoured internal passages that minimize exhaust gas flow restriction and optimize the pulse energy delivered to the turbocharger for rapid boost response.
Installing a genuine OEM exhaust manifold preserves the designed exhaust flow characteristics, turbocharger response, and engine compartment thermal management. The 1006867720 identifier provides complete traceability to Shacman’s rigorous metallurgical standards and precision manufacturing quality assurance processes for this mission-critical engine exhaust component.

The manifold gathers the pulsed exhaust flow from each cylinder and merges the streams smoothly into a single outlet, minimizing turbulence and preserving the kinetic energy of the gas pulses that drive the turbocharger turbine wheel with maximum efficiency.
The 1006867720 manifold material is specifically formulated to withstand continuous exposure to exhaust gas temperatures exceeding 800 degrees Celsius without cracking, warping, or losing its sealing integrity against the cylinder head flange.
The precisely engineered runner lengths and internal volumes are tuned to deliver strong, sequential exhaust pulses to the turbocharger, minimizing lag and ensuring rapid boost pressure build-up when the driver demands acceleration and pulling power.
The exhaust manifold 1006867720 is mounted directly to the cylinder head exhaust port flange on the Shacman X5000 engine. Before installation, the cylinder head flange surface and the manifold mounting face must be meticulously cleaned of all old gasket material, carbon deposits, and corrosion. A new OEM exhaust manifold gasket is positioned over the cylinder head studs or aligned with the bolt holes. The manifold is carefully lifted into position, and all mounting fasteners are installed finger-tight. The fasteners are then torqued incrementally in the specified sequence, typically starting from the center ports and working outward in a spiral pattern, to the exact factory torque specification. This progressive, sequenced tightening is absolutely critical for achieving uniform gasket compression and preventing manifold warping. After the manifold is secured, the turbocharger is mounted to the manifold outlet flange with a new gasket, and its fasteners are torqued to specification. The exhaust downpipe, EGR connections, and any sensor probes are then reconnected. The engine should be started and the manifold-to-head joint visually inspected for any signs of exhaust gas leakage before the heat shield is reinstalled.
Each exhaust manifold produced under OEM number 1006867720 is manufactured using a precision casting process. High-silicon molybdenum ductile iron is poured into precision sand molds or investment casting molds that create the exact internal and external geometry specified by Shacman engineering. The casting process is carefully controlled to ensure a dense, void-free structure with uniform wall thickness throughout the manifold body. The cast manifold is then heat-treated to relieve internal casting stresses and to stabilize the material for the extreme thermal cycling it will experience in service.
After heat treatment, the manifold undergoes precision machining operations. The cylinder head mounting flange is machined perfectly flat to ensure a leak-free seal with the gasket. The turbocharger mounting flange is similarly machined flat and the mounting stud holes are drilled and tapped. The exhaust ports are inspected for casting flash or obstructions and are dressed as needed to ensure smooth gas flow. Each manifold is dimensionally inspected for flange flatness, port alignment, and overall geometry. The manifold is then coated with a high-temperature protective finish, preserved, and packaged in a Shacman branded container displaying the 1006867720 part number.
The exhaust manifold should be visually inspected during routine engine service for any signs of soot tracks indicating a gasket leak, visible cracks in the casting, or broken mounting ears. An audible ticking or puffing sound that increases with engine load is a classic symptom of an exhaust manifold leak. The manifold should also be inspected for any signs of warping, which can be checked by placing a straightedge across the cylinder head mounting flange if the manifold is removed for other service.
If the manifold is cracked, warped, or has eroded sealing surfaces, it must be replaced with a new 1006867720 component. Attempting to weld repair a cracked cast iron exhaust manifold is generally not recommended, as the weld area will have different thermal expansion characteristics than the surrounding casting and will likely crack again. If the manifold has been removed, it is mandatory to replace the exhaust manifold gasket with a new OEM gasket upon reinstallation. A new manifold will restore the designed exhaust flow, turbocharger response, and gas-tight sealing that are essential for engine performance, fuel efficiency, and cab safety from exhaust gas intrusion.

Investing in the genuine Exhaust Manifold 1006867720 is a decision that directly protects the turbocharger performance and operational safety of your Shacman X5000 engine. Aftermarket manifolds cast from inferior materials can crack under the extreme thermal cycling of diesel engine operation, causing exhaust leaks that reduce turbocharger boost pressure and allow deadly carbon monoxide gas to enter the vehicle cab. A cracked manifold can also direct a jet of hot exhaust gas onto adjacent fuel lines, wiring, or hydraulic hoses, creating an immediate fire hazard.
The OEM manifold’s specific material grade, internal runner geometry, and precise flange machining were validated through extensive computer modeling of exhaust gas dynamics and grueling engine dynamometer durability testing. Shacman engineers optimized every aspect of this manifold to deliver the exact exhaust flow characteristics and thermal durability that the X5000 engine demands. The 1006867720 manifold provides the reliable exhaust gas collection and turbocharger drive energy that are fundamental to the engine’s rated power, torque, and fuel efficiency.
Professional engine rebuilders and fleet maintenance technicians worldwide insist on the 1006867720 exhaust manifold for its guaranteed metallurgical quality, precise fit, and proven durability under the most punishing thermal conditions. This heavy casting is the critical first component in the engine’s exhaust energy recovery chain. Trust only the exhaust manifold that Shacman engineered and certified for the uncompromising requirements of the X5000 heavy truck platform.
The exhaust manifold 1006867720 operates under the most severe thermal conditions of any engine component. Exhaust gas temperatures at the manifold inlet can exceed 800 degrees Celsius during sustained full-load operation, causing the manifold to glow a visible cherry red in low-light conditions. The high-silicon molybdenum ductile iron material is specifically formulated to maintain its strength and resist oxidation at these extreme temperatures, while also accommodating the rapid thermal expansion that occurs when the engine goes from cold start to full power in a matter of seconds.
The exhaust manifold mounting fasteners are subjected to the same extreme thermal cycling as the manifold itself and are made from high-temperature alloys to prevent stretching and loosening. When reinstalling a manifold, it is critical to use the correct fasteners and to apply any specified anti-seize compound or thread lubricant. After the engine has been run through several thermal cycles following manifold installation, the fastener torque should be rechecked to compensate for any initial relaxation of the gasket and thermal settling of the manifold casting.
