Engine Cylinder Head ISUZU 4JJ1 / 4JK1 Tier 3
High-quality cylinder head with part number 8982230192. Designed for the reliable, 4-cylinder ISUZU 4JJ1 (3.0L) and 4JK1 (2.5L) engines meeting the Tier 3 emissions standard. These units power popular construction machinery from brands such as Hitachi, Case, and JCB. The cylinder head is a key component of the combustion chamber, responsible for maintaining sealing, proper compression, and optimal charge exchange.
Product Features:
- Solid casting: Made of a high-grade cast iron alloy, characterized by exceptional resistance to extreme temperatures, which is crucial in modern Tier 3 standard engines.
- Machining precision: Perfectly contoured intake, exhaust, and cooling channels guarantee optimal gas and fluid flow, protecting the engine from overheating.
- Ready for assembly: The cylinder head is precisely machined, features prepared valve seats, and a perfectly flat contact surface with the block.

Technical Tip: When installing a new cylinder head, it is absolutely essential to use a new gasket of the appropriate thickness selected based on piston protrusion, and a completely new set of head bolts. The bolts must be tightened with a torque wrench strictly according to the manufacturer's instructions (correct sequence, torque, and angles). Before installation, also check the flatness of the upper surface of the engine block.
