Product Overview

Keep your heavy earthmoving machinery operating at peak performance with our Premium Cast Iron Cylinder Liner (1-12121-143-0). This high-grade engine sleeve is custom-engineered specifically for the Isuzu 6WG1 diesel engine, widely utilized in Hitachi large-scale excavators and heavy-duty industrial equipment.

Faced with the continuous high-load, high-temperature demands of mining and construction sites, standard liners fail prematurely. Our 6WG1 engine sleeves are cast from an advanced pearlitic boron-iron alloy, guaranteeing excellent structural integrity, rapid heat dissipation, and superior wear resistance under extreme hydraulic and mechanical stresses.

Key Structural & Performance Benefits

• Precision Flange Machining: Developed strictly to the 147mm × 151.5mm × 267mm × 158.3mm geometry. The 158.3mm flange ensures a perfect counterbore seating within the 6WG1 engine block, preventing head gasket leakage.

• Advanced Plateau Honing Finish: The precise cross-hatch pattern on the inner bore ensures optimal engine oil film retention. This reduces friction with the piston rings, drastically lowers blow-by, and stabilizes oil pressure during heavy digging cycles.

• Exceptional Cavitation Resistance: The specialized alloy material structure protects the outer liner wall from liner pitting and cavitation erosion caused by intense cooling system shockwaves.

Complete Cross-Reference Guide

• OEM Interchanges: 1-12121-143-0, 1121211430, 1-12121143-0
