Product Overview

In Komatsu 6D125 engine service, the bottom gasket kit must match the surrounding components rather than being selected by appearance alone. This bottom gasket kit groups sealing and service components intended to support lower-engine and crankcase repair. This replacement is intended for the corresponding application with reference number 6150-K2-9901 / 6151-K2-9901.

Before installation, the component and engine information should be compared so the replacement matches the required configuration and repair scope.

Why This Part Matters

Using a matched kit can simplify parts sourcing during repair, but exact contents depend on the engine version and the selected kit configuration. Correct identification helps ensure the required gaskets and seals correspond with the components being disassembled. During replacement, matching the specification is important. Assuming that every kit for the same engine family contains identical components can lead to missing or unnecessary parts.

For rebuild planning, it is useful to compare the repair scope with the parts already being replaced. Some jobs require only upper-engine sealing components, while others involve the crankcase, oil pan, front and rear covers, or other lower-engine joints. Because engine revisions can change gasket shapes and included seals, the kit reference number should be checked together with the engine model rather than relying on the model name alone.

When ordering several repair items together, our team can also help cross-check related bearings, pistons, liners, valves, oil seals, and other components. This makes it easier to organize one repair order while keeping the final component selection based on the actual engine configuration and the customer's required repair scope.
