FAQ

Q1: Is this a complete cylinder head assembly, or does it require additional components?
A1: This is sold as a complete, ready-to-install cylinder head assembly. It includes the cast head with integrated valve guides and pre-machined surfaces for the valve seats, head gasket, and camshaft. Valves, springs, and injectors are typically not included unless specified in a kit.

Q2: How do I confirm this part will fit my specific Komatsu PC400-7 excavator?
A2: The most reliable method is to cross-reference the part number currently on your engine. Match it with our listed OEM numbers (6156-11-1100/1101/1102). We also recommend providing your machine’s serial number (SN) to our technical support team for final verification before purchase.

Q3: What are the signs that my Komatsu 6D125 engine needs a cylinder head replacement?
A3: Common indicators include loss of engine power, white smoke from the exhaust (coolant burning), coolant loss without visible external leaks, overheating, and compression loss. A mechanic should perform a compression test and coolant system pressure test to diagnose a cracked or warped cylinder head definitively.
