4HG1 Cylinder 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 cylinder block fits light trucks (ELF N Series), heavy trucks (GIGA C Series) and excavators (EX200-5), compatible with core engines 4HK1-TC and 6UZ1-TC. It is made of high-strength wear-resistant alloy cast iron (tensile strength ≥580MPa), with key dimensions meeting IT7 grade: the cylinder bore cylindricity error is ≤0.006mm, the main bearing bore coaxiality is ≤0.012mm, and both have a tolerance of ±0.01mm.
Product Advantages
It undergoes ultrasonic flaw detection (no internal defects), a 2.4MPa water pressure test (holding pressure for 14 minutes without leakage) and fatigue resistance testing, featuring resistance to heavy-load impact and a 60% longer service life. It enables precise adaptation per OE standards to reduce installation and debugging time, and is compatible with multiple types of commercial vehicles and construction machinery, solving accessory matching issues.
