Weichai 618 Camshaft

Weichai WD618 camshaft 612600050087 is a key component of the engine valve train system. It precisely controls the opening and closing timing of intake and exhaust valves to guarantee stable air intake and exhaust process. It directly determines engine power output, fuel consumption and running smoothness. This camshaft is an essential replacement spare part for heavy-duty commercial vehicles and engineering machinery maintenance.

This camshaft with part number 612600050087 is specially developed matching Weichai WD618 diesel engine, widely fitted on Howo dump trucks, tractors, Shacman heavy trucks, large wheel loaders and stationary generator sets. The cam profile is strictly designed according to original drawing standards to maintain factory valve timing parameters, effectively avoiding insufficient power, excessive fuel consumption and abnormal exhaust caused by mismatched camshaft.

Manufactured by high-quality material with integrated forming technology. All cam lobes and main journals are precisely ground, followed by high-frequency induction quenching treatment. Every finished camshaft undergoes strict dimensional inspection, hardness testing and appearance flaw detection before delivery, ensuring stable quality for long-term heavy-load operation.Interchangeable OEM Part No.: 612600050087

Product Advantages

Premium Raw Material & Outstanding Wear Resistance

• Adopt high-strength alloy steel / ductile iron blank, excellent structural rigidity, anti-fatigue and anti-deformation performance, adapting to long-distance transportation, frequent start-stop and heavy-load working conditions
• Cam lobe and shaft journal surface induction quenching, uniform hardened layer, greatly improving wear resistance, effectively preventing early pitting and abrasion of cam surface
• Optimized cam transition arc design, reduce instantaneous impact stress between cam and tappet, lower valve train noise

OEM Standard Precision Machining

• Strictly implement original dimension tolerance standards, accurate cam profile, consistent valve lift and timing parameters, direct installation without modification
• Superfinishing grinding on working surfaces, easy to form stable lubricating oil film, reduce friction loss, prevent tappet scuffing
• Strict straightness control, avoid eccentric wear after assembly, extend service life of camshaft bush and tappet assembly
