This aftermarket overhaul gasket set is built for the Cummins 6D114 diesel engine used in Komatsu PC300 and PC360 excavators. It covers the sealing needs of a full engine rebuild, helping you restore compression, oil control and coolant integrity in one kit.
Reference part numbers: 138-K1-0102 and 6138-K2-0102. Please confirm your engine and machine details before ordering.
The 6D114 full gasket kit is used when the engine is opened for top-end or complete overhaul work. It provides the gaskets and seals needed to reassemble the engine after inspection or replacement of pistons, liners, bearings and valves.
Typical applications include cylinder head sealing, oil pan and timing cover sealing, intake and exhaust manifold sealing, and other joint areas that must be leak-free after rebuild.
Along with the overhaul gasket set, we supply matching 6D114 components for the same rebuild:
Ordering these together helps keep tolerances and fit consistent across the rebuild.
Engine model and machine model are the main checks. The 6D114 is used in PC300 and PC360 excavators, but configurations can vary by serial number and market. If you are unsure whether this kit matches your unit, send your engine number and machine serial number for confirmation.
