Import 6b5.9 Engine Exhaust Manifold 3917700 — Buy in wholesale FOB from Supplier in China

The 6b5.9 Engine Exhaust Manifold 3917700 is a genuine OEM component designed for Cummins 6B5.9 diesel engines, ensuring precise fitment and compatibility with the engine’s exhaust system. This part, listed under part number 3917700, is engineered to withstand high-temperature exhaust gases, with typical operating ranges up to 800°C for cast iron manifolds used in heavy-duty applications. The manifold directs exhaust flow from the engine cylinders to the turbocharger or exhaust pipe, maintaining optimal backpressure and thermal efficiency.

Constructed from heat-resistant cast iron, this exhaust manifold is built to endure thermal cycling and combustion pressures typical in vehicle, marine, and construction machinery applications. The surface finish and material composition adhere to industry standards for Cummins engine parts, with typical hardness values of 180-220 HB for durability. The design integrates with compatible intake manifolds (e.g., 3917761, 5262696) and is part of a broader lineup covering engines like 4BT, 6BT, 6CT, and ISDe series, as referenced in the supplier’s catalog.

This manifold is primarily sourced by OEMs and distributors servicing Cummins-powered equipment in sectors such as transportation, agriculture, and power generation. Buyers in South America, the Middle East, Southeast Asia, and Africa frequently procure these parts for aftermarket repairs or fleet maintenance. The supplier, based in Shiyan’s engine parts wholesale hub, offers bulk supply with packaging tailored for international shipping, though exact MOQ and lead times require direct confirmation.

Shiyan Hancom Power Co., Ltd is based in Zhangwan District, Shiyan, Hubei Province, a region recognized as China’s largest wholesale market for engine parts. The company operates from Room 6034, Block A, Wanda Plaza, Hanjiang Road, positioning it within a key industrial cluster for automotive and machinery components. Its focus spans a broad range of engine parts, including components for Renault, Foton Truck, and Komatsu machinery, with a stated specialization in Cummins engine systems such as 6B5.9, 6BT, and ISDe series.

The supplier’s profile indicates a long-standing presence in the engine parts sector, serving customers across South America, the Middle East, Southeast Asia, and Africa. While the response rate and average response hours are currently listed as zero, the company’s catalog reflects a deep inventory of OEM and aftermarket parts, from exhaust manifolds to intake pipes and covers. The trust tier classification as 'harbor' suggests a baseline level of verification, though buyers are advised to confirm specifics like certifications, lead times, and quality control processes directly with the supplier.
