FAQ

Q1: Does this gasket kit include the head gasket and all lower engine seals?
A1: Yes, this is a full gasket kit designed for a complete engine overhaul. It typically includes the cylinder head gasket, intake/exhaust manifold gaskets, valve cover gasket, oil pan gasket, front and rear crankshaft seals, and other necessary seals for the 6D125 engine. However, we recommend verifying the kit contents against your engine’s specific requirements before installation.

Q2: Is this kit compatible with both the 6D125 and 6D125-1 engine variants used in the PC400-5?
A2: This kit is primarily designed for the standard 6D125 engine found in the Komatsu PC400-5. While many gaskets are shared across variants, some differences may exist in later 6D125-1 engines. Please check the specific OEM part numbers (6151-K1-3000 or 6151-K2-3000) on your engine’s service manual or old gaskets to confirm compatibility.

Q3: What is the recommended installation procedure for this gasket kit?
A3: Installation should be performed by a qualified diesel mechanic following the Komatsu service manual for the 6D125 engine. Key steps include: ensuring all mating surfaces are clean and flat, applying the correct torque sequence and specifications for the head bolts, and using a thin layer of sealant where specified. We recommend replacing the head bolts or studs as per the manufacturer’s guidelines for optimal sealing.
