FAQ

Q1: Is this cylinder head a direct replacement for the original Komatsu part 8-98023-526-0?
Yes, this aftermarket cylinder head is manufactured to match OEM dimensions and specifications. It is a direct bolt-on replacement for the original Komatsu part number 8-98023-526-0. No modifications are required for installation on the PC300-8 with the Isuzu 6HK1 engine.

Q2: What other components should I replace when installing a new cylinder head?
For best results and to prevent future failures, we recommend replacing the cylinder head gasket, intake/exhaust manifold gaskets, valve stem seals, and head bolts (torque-to-yield) simultaneously. If the old cylinder head failed due to overheating, also check the oil cooler and radiator for blockages.

Q3: How can I verify if this cylinder head fits my specific engine serial number?
The Isuzu 6HK1 (6D114) engine has several variants. Check your engine serial number plate. This cylinder head is compatible with most 6HK1 engines found in Komatsu PC300-8 machinery. If your engine number starts with “6HK1” and has a “T” (turbocharged) designation, it is highly likely to match. Please contact our technical support with your engine serial number for final confirmation before ordering.
