Mercedes OM471 Cylinder Block

Product Name: Cylinder BlockApplicable Engine: Mercedes OM471Material: High-strength rigid alloy cast ironMatching Equipment: Heavy-Duty Trucks, Long-Distance Coaches, Industrial Generator Sets

Manufactured strictly in accordance with OEM dimensional tolerances for direct bolt-on replacement without modification. Main bearing saddles, cylinder bores and mounting joint surfaces are precisely bored and milled to guarantee assembly concentricity and flatness. Optimized integrated flow channel design ensures stable lubrication circulation and balanced heat dissipation. This cylinder block adopts wet replaceable cylinder liner structure. All finished blocks pass non-destructive flaw detection and hydraulic pressure leakage testing before delivery. Bare cylinder blocks and pre-assembled blocks fitted with wet cylinder liners are both available for supply.

Product Advantages

Ultra-Rigid Integrated Cast Iron Structure

• Premium high-strength alloy cast iron casting, deep-skirt cylinder block structure delivers outstanding rigidity, strong anti-deformation and anti-cracking capacity for long-term full-load highway operation
• One-piece integrated oil and cooling water passages eliminate joint leakage risks, effectively reduce oil seepage and coolant leakage faults
• Matched with replaceable wet cylinder liners, convenient for partial overhaul and later maintenance
• Designed for continuous heavy-duty long-distance transportation working conditions

Precision OEM Standard Machining

• Fully processed to original factory drawing tolerance standards, consistent dimensional accuracy for all hole positions and mounting surfaces to achieve perfect assembly matching
• High-precision finishing of main bearing housings prevents eccentric wear of crankshaft, extends service life of crankshaft and bearing shells
• Ultra-fine sealing surface machining thoroughly blocks oil, water and air leakage after installation, greatly lowering one-time overhaul failure rate

Wide Matching & Stable Aftermarket Supply

• Exclusively matched with Mercedes OM471 turbocharged intercooled six-cylinder power units, widely fitted on Mercedes-Benz Actros heavy trucks
• Mature aftermarket heavy-duty spare part with sufficient stock and fast global delivery
• Flexible supply modes: bare cylinder blocks or finished units pre-installed with wet cylinder liners for bulk order customization
