FAQ

Q1: Is this gasket kit a direct replacement for the original Komatsu parts?
Yes, this kit is manufactured to match the exact specifications of the OEM parts (6151-12-1810 and 6155-K2-9900). It is designed to be a direct, bolt-on replacement for the Komatsu 6D125, 6D125-2, and 6D125E-2A engines. However, we always recommend comparing the gaskets with your original parts to ensure a perfect match for your specific engine variant.

Q2: What is included in this Engine Gasket Kit?
This is a comprehensive kit that typically includes all major gaskets and seals for the cylinder head, oil pan, valve cover, front and rear crankshaft seals, and other critical engine points. While the exact contents may vary slightly by engine configuration, it is designed to provide everything needed for a major gasket replacement. Please contact us if you require a detailed list of components for your specific engine serial number.

Q3: Do I need any special tools or sealants for installation?
This kit is designed for professional installation. While most gaskets are pre-formed for a direct fit, we recommend using a high-quality thread locker on specific bolts and a thin layer of silicone sealant on certain joints (like the oil pan rail) as per the Komatsu service manual. Standard mechanic tools are sufficient for the job. We advise having the engine’s technical manual on hand for torque specifications and installation procedures.
