FAQ

Q: Is this kit suitable for a full engine rebuild on a Komatsu PC300 excavator?

A: This is a Bottom Repair Kit, which specifically contains the gaskets and seals for the lower engine block (oil pan, rear main seal, etc.). It does not include top-end components like head gaskets or valve stem seals. For a full rebuild, you would typically need this kit combined with a separate top-end gasket set. Always confirm your engine serial number with our sales team to ensure the correct kit selection.

Q: How do I verify that this 6261-K2-9900 kit will fit my specific engine?

A: The primary identifier is the engine model: 6D140-5. This number is usually stamped on the engine data plate located on the valve cover or side of the engine block. Additionally, you can visually compare the old gasket with the new ones in the kit. If you have the original part number from your old kit, please match it against the 6261-K2-9900 reference.

Q: What is the recommended storage and handling for this gasket kit before installation?

A: Store the kit in its original packaging in a cool, dry environment away from direct sunlight and extreme temperatures. Avoid bending or damaging the gaskets. Before installation, inspect all components for any transit damage. It is recommended to clean the mating surfaces thoroughly and follow the engine manufacturer’s torque specifications and sequence for all fasteners to ensure a proper seal.
