4HF1 Engine Block
Compatible with mainstream Isuzu engines such as 4JJ1 and 4JK1, it covers core commercial vehicle models. Undergoing original factory-level quality inspection, the engine block has a stable structure and high fatigue resistance, suitable for high-frequency heavy-load working conditions. Its tight sealing performance eliminates leakage risks, ensuring long-term stable output of the engine and reducing maintenance costs.
Product Description
- The Isuzu basic engine block is suitable for light trucks (ELF N Series), heavy-duty trucks (GIGA C Series), and excavators (EX200-5), and is compatible with engine assemblies including 4HK1-TC 3.0T and 6UZ1-TC 7.8T. The cylinder block is made of high-strength cast iron (tensile strength ≥280MPa), and the cylinder head is made of aluminum alloy. Key dimensions meet IT7 grade, with cylinder bore tolerance ≤±0.005mm and crankshaft hole coaxiality ≤0.008mm.
Product Advantages
It has undergone high-pressure air tightness testing (leakage ≤4kPa/min) and heavy-load durability testing (1000 hours of continuous full-load operation), featuring strong resistance to heavy loads and fatigue. It achieves precise adaptation in line with OE standards, improving assembly efficiency by 30%. Compatible with multiple types of commercial vehicles and engineering equipment, it reduces the maintenance cost and adaptation difficulty of the power assembly.
