Mercedes-Benz OM314 Crankshaft

The OM314 crankshaft is developed for Mercedes-Benz OM314 four-cylinder engine platform, compatible with Mercedes medium-duty trucks, light commercial vehicles, passenger buses, farm machinery and engineering equipment. It features stable power transmission performance, excellent fatigue resistance and long service life, satisfying customers’ demands for low breakdown rate and reliable continuous operation.

Manufactured strictly complying with OEM dimensional standards, adopting integral forging technology and multi-procedure precision machining. All main journals and connecting rod journals are ultra-precisely processed to ensure perfect cooperation with bearing shells, connecting rod assemblies and flywheel. Each finished crankshaft undergoes 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.: 3140300701, 3140301001

Product Advantages

High-Strength Forged Steel & Superior Structural Durability

• High-quality alloy forged steel blank, great bending resistance and fatigue crack resistance, suitable for diversified working conditions including highway transportation, farmland operation and engineering sites
• Optimized crank throw and counterweight layout, evenly disperses alternating stress, effectively avoiding permanent deformation under continuous load operation
• Induction quenching treatment applied on main journals, rod journals and transition fillets, greatly boosting wear resistance and crack resistance

Precision OEM Standard Machining

• Completely processed according to original factory tolerance standards. Stable journal diameter, straightness and runout tolerance, supporting direct installation without secondary modification
• Superfine journal surface treatment helps form uniform lubricating oil film, effectively preventing bearing burning and shaft locking failures
• High-standard dynamic balance calibration reduces overall engine vibration and lessens extra wear of engine auxiliary components

Accurate Matching & Stable Supply

• Exclusively matched with Mercedes-Benz OM314 engine, widely installed on Mercedes medium trucks, light commercial vehicles, buses, agricultural machinery and construction machinery
• Mature aftermarket spare part for classic European diesel engines, sufficient inventory and fast delivery
• Supply options: brand-new standard crankshaft; bulk order customization supported
