Mercedes Cylinder Block (OM651 Engine)

✓ Product: Cylinder Block
✓ For Mercedes OM651 Inline 4-Cylinder Diesel Engine
✓ Widely used for Mercedes passenger cars, light commercial vans and small bus engine overhaul

Mercedes OM651 cylinder block is the core load-bearing base component of OM651 inline four-cylinder diesel engine. It is integrally cast with high-strength alloy cast iron, equipped with built-in lubricating oil galleries and cooling water channels. Optimized compact structure enhances structural stability, capable of enduring long-term cyclic loads, high temperature and pressure. It acts as an essential replacement component for overhauling Mercedes light commercial vehicles and passenger vehicles.

Overview

Product Details

Product Name: Cylinder BlockApplicable Engine: Mercedes OM651Material: High-strength rigid alloy cast ironMatching Equipment: Mercedes Passenger Cars, Light Commercial Vans, Small Buses

Manufactured strictly following 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. All finished cylinder blocks pass non-destructive flaw detection and hydraulic pressure leakage testing before shipment. Bare cylinder blocks are available for supply.

Product Advantages

High Rigidity Integrated Cast Iron Structure

Premium high-strength alloy cast iron casting, compact four-cylinder layout features excellent rigidity, strong anti-deformation and anti-cracking performance for daily urban and highway driving conditions
One-piece integrated oil and cooling water passages eliminate joint leakage risks and effectively reduce oil seepage and coolant leakage failures
