Mercedes-Benz OM471 Forged Steel Crankshaft

The OM471 crankshaft is specially customized for Mercedes-Benz OM471 inline 6-cylinder heavy-duty diesel engines, fully compatible with Euro VI emission standard engine models equipped on Actros and Arocs heavy-duty trucks. It strictly implements factory original dimensional standards and production processes, with accurate main journal and connecting rod journal tolerance, excellent overall rigidity and strong impact resistance, adapting to long-distance transportation, engineering operation and other high-intensity working scenarios.

Made of high-quality 42CrMoA alloy steel through integral forging, quenching and tempering heat treatment and surface hardening process, the crankshaft effectively eliminates internal stress and improves overall fatigue resistance and wear resistance. The optimized counterweight structure and professional dynamic balance calibration reduce engine vibration and friction loss during operation, ensuring stable and efficient output of engine power system and reducing long-term operating failure rate.

Product Advantages

High-Strength Forging & Super Durability

• Adopts premium 42CrMoA alloy forged steel integral forming process, with dense internal structure, which can withstand ultra-high torque and explosive load of heavy-duty engines, effectively avoiding deformation, bending and fracture.
• Matched with professional quenching and tempering heat treatment process, the overall rigidity and fatigue life are greatly improved, adapting to long-term high-intensity operation of heavy-duty vehicles.

Precision Machining & Low Operation Loss

• Precision grinding of main journal and connecting rod journal with ultra-high dimensional accuracy and smooth surface, effectively reducing shaft friction wear and engine oil consumption.
• Strict dynamic balance calibration to eliminate operating vibration, reduce engine noise, and improve the overall stability and comfort of vehicle operation.
• Optimized journal fillet reinforcement design, which disperses stress concentration, improves impact resistance, and greatly extends service life.

Original Standard & Easy Installation

• Produced in strict accordance with original factory parameters, with standard overall dimension, journal size and mounting hole position, realizing direct replacement and plug-and-play installation without modification.
• Widely compatible with OM471 series Euro VI emission heavy-duty diesel engines, fully matching supporting models such as Mercedes-Benz Actros and Arocs heavy trucks.
• Complete factory quality inspection procedures, stable product consistency, reliable quality, suitable for engine factory assembly and aftermarket maintenance replacement.
