FAQ

Q1: Is this cylinder head a direct bolt-on replacement for my Komatsu PC200-7 excavator with a 6D110 engine?
A: Yes, this cylinder head assembly is designed as a direct OEM replacement for Komatsu 6D110 engines, including those in PC200-7 models. It includes pre-installed valves, guides, and seats. However, we recommend using a new cylinder head gasket and tightening the head bolts to the manufacturer’s specified torque sequence (typically 120-140 Nm in stages).

Q2: Does this cylinder head come with valve stem seals and camshaft bearings?
A: The assembly includes valves, guides, seats, springs, and retainers. Valve stem seals and camshaft bearings are typically not pre-installed due to varying wear tolerances. We advise installing new seals and checking camshaft bearing journals during reassembly for optimal performance.

Q3: What should I do if my existing cylinder head has a different casting number than the one listed?
A: If your original part number differs (e.g., 6D110-1 vs. 6D110-2), please verify the engine serial number and cylinder head dimensions (bolt pattern, water jacket layout). Our technical support team can cross-reference your specific number to confirm compatibility. We recommend sending a photo of the old part number for fastest verification.
