FAQ

Q1: Is this a complete kit for a full engine rebuild?
A1: This is a comprehensive top-end overhaul kit. It includes the major wear components for the cylinder head and block assembly (pistons, valves, gaskets, bearings). For a complete rebuild, you may need to source additional bottom-end components like main seals or a crankshaft kit based on your engine’s condition.

Q2: How do I confirm this kit fits my specific Komatsu PC400-7 excavator?
A2> While designed for the PC400-7 and PC450-10 models, the most accurate fitment is determined by the engine model and serial number. We recommend matching the engine model (6D125 or SAA6D125-7) and cross-referencing the part number 6252-31-2110 with your machine’s service manual or current parts list before ordering.

Q3: What is the typical lead time for delivery to Europe or North America?
A3: Lead times vary by destination and shipping method. For standard sea freight to major European or North American ports, expect 25-40 days.
