Mercedes Cylinder Block (OM473 Engine)

✓ Product: Cylinder Block
✓ For Mercedes OM473 Inline 6-Cylinder Diesel Engine
✓ Widely used for heavy-duty tractors, large haulage trucks, luxury coaches, industrial generator overhaul

Mercedes OM473 cylinder block acts as the core load-bearing base component of OM473 inline six-cylinder heavy-duty diesel engine. It is integrally cast with high-strength alloy cast iron, featuring built-in lubricating oil galleries and cooling water channels. The reinforced deep-skirt design upgrades overall structural rigidity, which can withstand long-term heavy alternating loads, extreme high temperature and pressure. It is an essential replacement spare part for overhauling Mercedes high-power commercial vehicles and fixed power generation equipment.

Overview

Product Details

Product Name: Cylinder BlockApplicable Engine: Mercedes OM473Material: High-strength rigid alloy cast ironMatching Equipment: Heavy-Duty Tractors, Large Haulage Trucks, Luxury 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 Reinforced Cast Iron Structure

Premium high-strength alloy cast iron casting, reinforced deep-skirt structure delivers ultra-high rigidity, remarkable anti-deformation and anti-cracking performance for long-term full-load heavy haul operation
One-piece integrated oil and cooling water passages eliminate splicing leakage risks, effectively cut down oil seepage and coolant leakage malfunctions
Matched with detachable wet cylinder liners, simplifying partial maintenance and engine overhaul procedures
Designed for continuous heavy-duty working conditions such as mountain haulage, long-distance logistics and stable power generation

Precision OEM Standard Machining

Fully processed to original factory drawing tolerance standards, all hole positions and mounting surfaces maintain unified dimensional accuracy to realize perfect assembly fit
High-precision finishing of main bearing housings avoids eccentric wear of crankshaft, prolongs service life of crankshaft and bearing shells
Ultra-fine machining on sealing surfaces completely prevents oil, water and air leakage after installation, significantly reducing one-time overhaul failure rate
