description

The cylinder head assembly is the upper core component of diesel engine, equipped with valves, valve springs and valve seats. It seals the top of cylinder to form combustion chamber, integrates intake ducts, exhaust ducts, cooling water passages and lubricating oil passages, and cooperates with injectors to realize combustion and power output. Warped deck surface, poor valve sealing, water channel crack or casting defects will cause blown head gasket, water leakage, air leakage, low cylinder pressure, abnormal exhaust and power loss. In severe cases, coolant entering cylinder may lead to engine breakdown.

FAQ 

Q: Can a slightly distorted cylinder head be reused after deck resurfacing?
A: Machining repair is acceptable within OEM allowable material removal limit. Replace assembly if removal exceeds limit or hidden cracks exist.

Q: Why replace cylinder head bolts together with new cylinder head?
A: Cylinder head bolts are stretch-type fasteners. Metal fatigue occurs after disassembly and reuse may result in bolt breakage and blown gasket.
