Centrifugally Cast High-Alloy Cast Iron Cylinder Block Liner Wet Type with O-Rings Direct OEM Replacement for Isuzu CXZ51 6WF1 6WG1

• OE Quality: Manufactured to Isuzu dimensional and material specifications for perfect fit and long service life
• Centrifugal Casting: Produces dense, uniform grain structure for high strength and wear resistance
• Hardened Bore Surface: Provides excellent wear resistance for piston rings
• Precision Machined: Accurate bore size and roundness for proper ring seal
• Plateau Honed Finish: Optimized surface finish for immediate ring seating and reduced break-in time
• Corrosion Resistant: Alloy composition resists cavitation erosion in wet liner applications
• Restores Engine Performance: Eliminates blow-by, low compression, and high oil consumption
• Direct Replacement: Drop-in or press-fit installation
• Cost-Effective: Affordable alternative to genuine OEM liners

This cylinder block liner is specifically designed for Isuzu CXZ51 trucks with 6WF1 or 6WG1 engine.

• ISUZU CXZ51 (heavy-duty truck, 6×4 or 8×4 configuration)
• May also fit other Isuzu heavy models with 6WF1/6WG1 engine (e.g., CYZ51K, EXZ51K, CXZ81) - verify

Installation steps (overview for wet liners - typical for 6WF1/6WG1):

1. Remove cylinder head, pistons, and old liners from block (use a liner puller)
2. Clean block liner bores - remove rust, old O-ring residue, and debris
3. Inspect block counterbores - check for damage or corrosion
4. Install new O-rings onto the new liners (upper and lower seals)
5. Lubricate O-rings and liner outer surface with clean engine oil or soapy water
6. Press or drop new liners into the block bores - ensure they seat fully against the counterbore
7. Measure liner protrusion above the block deck using a dial indicator and straight edge. Protrusion should be within OE spec (typically 0.05-0.15mm). Adjust with shims if necessary
8. Hone the liners to final size (if needed) and to create a cross-hatch pattern
9. Clean liners thoroughly - remove honing residue
10. Install new pistons and rings, then cylinder head with new head gasket
11. Fill coolant and check for leaks
