Mercedes-Benz OM501 Crankshaft

The OM501 crankshaft is specially developed for Mercedes-Benz OM501 engine platform, compatible with Mercedes Actros heavy-duty trucks, large intercity passenger buses, stationary generator sets, marine power equipment and large construction machinery. It features stable power transmission, excellent anti-fatigue property and long service life, meeting the demands of repair shops and fleets for reliable engine overhaul parts.

Produced strictly in accordance with OEM drawing dimensional standards, adopting integral forging technology and multi-process precision machining. All main journals and connecting rod journals are ultra-precisely machined to ensure perfect fit with bearing shells, connecting rod assemblies and flywheel. Every finished crankshaft passes strict magnetic particle crack inspection, hardness test and high-precision dynamic balance calibration before delivery. Standard size crankshaft is available from stock.Interchangeable OEM Part No.: 5010300701, 5010301101, 5010301501

Product Advantages

High-Strength Forged Steel & Outstanding Structural Durability

• Premium alloy forged steel blank with excellent bending resistance and fatigue crack resistance, suitable for highway transportation, construction sites, marine and other complex working environments
• Optimized crank throw and counterweight layout to evenly disperse alternating stress, effectively reducing permanent deformation risk under continuous high-load operation
• Induction quenching treatment on main journals, rod journals and transition fillets, greatly improving wear resistance and crack resistance

Precision OEM Standard Machining

• Fully processed according to original factory tolerance standards. Stable journal diameter, straightness and runout tolerance, supporting direct installation without secondary modification
• Ultra-fine journal surface processing facilitates the formation of uniform lubricating oil film, effectively preventing bearing burning and shaft seizure failures
• High-standard dynamic balance calibration reduces overall engine vibration and lowers extra wear of engine auxiliary components

Accurate Matching & Stable Supply

• Specially matched with Mercedes-Benz OM501 / OM501LA V6 engines, widely fitted on Mercedes Actros heavy trucks, large buses, construction machinery, generator sets and marine engines
• Mature aftermarket spare part for European diesel engines, sufficient inventory and fast delivery
• Supply options: brand-new standard size forged crankshaft; bulk order customization supported
