OM422 cast crankshaft is the core power transmission component of Mercedes-Benz OM422 V8 heavy-duty diesel engine. It converts reciprocating thrust of pistons into continuous rotational torque. Manufactured with high-strength ductile cast iron integrated casting technology and journal surface strengthening treatment. It can withstand long-term alternating impact loads under complex working conditions, serving as an essential replacement spare part for overhaul of classic Mercedes European heavy-duty engines.

Overview

Product Details

OM422 cast crankshaft is specially developed for Mercedes-Benz OM422 V8 engine platform, compatible with Mercedes heavy-duty trucks, passenger buses, stationary generator sets, marine power equipment and construction machinery. It delivers stable power transmission performance, excellent anti-fatigue performance and long service life, meeting the low-cost and reliable overhaul requirements of repair shops and fleets.

Manufactured strictly in accordance with OEM drawing dimensional standards, adopting integrated casting and multi-process precision machining technology. 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 in stock.Interchangeable OEM Part No.: 4220303701, 4220304301

Product Advantages

High-Strength Ductile Cast Iron & Cost-Effective Durability

Premium QT800 ductile cast iron blank, featuring good toughness and fatigue crack resistance, suitable for various working conditions such as highway transportation, construction sites and marine applications
Optimized integrated casting structure of crank throw and counterweight to evenly disperse alternating stress and reduce the risk of permanent deformation under continuous load operation
Induction quenching treatment on main journals, rod journals and transition fillets, greatly improving surface wear resistance and anti-cracking capacity

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 OM422 / OM422LA V8 engines, widely fitted on Mercedes heavy trucks, buses, construction machinery, generator sets and marine engines
Mature aftermarket spare part for classic European diesel engines with sufficient inventory and fast delivery
Supply options: brand-new standard size cast crankshaft; bulk order customization supported
