FAQ

Q: Is this gasket kit a direct fit for my Komatsu PC60-6 excavator with a 4D95 engine?

A: Yes, this kit (referencing 6204-K1-9900) is specifically designed for the Komatsu 4D95 and S4D95 engines found in the PC60-6 model. It includes all the upper engine gaskets (head gasket, valve cover, intake/exhaust manifold) and lower seals (oil pan, front/rear crankshaft seals) required for a complete overhaul. We recommend verifying your engine serial number against the OEM part 729436-92601 for absolute certainty.

Q: Can I install this kit myself, or should I hire a professional mechanic?

A: While the kit is designed for straightforward installation, we strongly recommend installation by a certified diesel mechanic. Proper torque sequences, surface cleaning, and sealant application are critical for the gasket set to perform correctly. Incorrect installation can lead to premature gasket failure and engine damage. The included high-temperature materials require careful handling to maintain their sealing properties.

Q: What is the difference between a “Full Gasket Kit” and a “Top End Gasket Kit”?

A: A Full Gasket Kit, like this one, is more comprehensive. It typically includes all gaskets and seals for the entire engine, from the valve cover down to the oil pan. This includes the head gasket, intake/exhaust manifold gaskets, valve stem seals, front and rear crankshaft seals, oil pan gasket, and more. A “Top End” kit usually only covers the cylinder head area. This kit ensures you have everything needed for a complete engine rebuild.
