Mitsubishi 6D34 Cylinder Block

Product Name: Cylinder BlockApplicable Engine: Mitsubishi 6D34Material: High-strength wear-resistant alloy cast ironMatching Equipment: Medium-Duty Trucks, Passenger Coaches, Construction Machinery, 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. All finished cylinder blocks pass non-destructive flaw detection and hydraulic pressure leakage testing before delivery. Bare cylinder blocks and pre-assembled blocks fitted with cylinder liners are both available for supply.

Product Advantages

High Rigidity Alloy Cast Iron Structure

• Premium high-strength wear-resistant alloy cast iron casting with great overall rigidity, excellent anti-deformation and anti-cracking performance, applicable to long-distance transportation and engineering heavy-load working conditions
• One-piece integrated oil and cooling water passages eliminate splicing leakage risks and effectively reduce oil seepage and coolant leakage failures
• Reinforced six-cylinder layout supports long-duration continuous heavy-load operation and extends the whole engine service life

Precision OEM Standard Machining

• Fully processed to original factory drawing tolerance standards, unified dimensional accuracy of all hole positions and mounting surfaces for perfect assembly fit
• High-precision finishing of main bearing housings avoids eccentric crankshaft wear and extends service life of crankshaft and bearing shells
• Superfine sealing surface processing completely prevents oil, water and air leakage after installation and reduces one-time overhaul failure rate

Wide Matching & Stable Aftermarket Supply

• Specially matched with Mitsubishi 6D34 naturally aspirated and turbocharged six-cylinder power units, compatible with various medium trucks and engineering equipment
• Mature aftermarket medium-duty engine spare part with abundant stock and fast delivery
• Flexible supply options: bare cylinder blocks or finished assemblies pre-installed with cylinder liners for bulk customization
