FAQ

Q: What is the difference between the 6159-K1-9900 and 6159-K2-9900 kits?

A: The 6159-K1-9900 is the Full Gasket Set, containing all gaskets for the entire engine (top and bottom end). The 6159-K2-9900 is the Upper Repair Kit, which includes smaller seals, O-rings, and specific gaskets for the cylinder head and valve train area. For a complete top-end overhaul, you may need both kits or the combined set offered here.

Q: Can I use this kit on a Komatsu PC400-8 or PC450-8?

A: No. This kit is specifically designed for the 6D125 and SAA6D125-7 engines found in the PC400-7 and PC450-10 series. The PC400-8 and PC450-8 models typically use the SAA6D125E-3 engine, which has a different gasket configuration. Please verify your engine model and serial number before ordering.

Q: Does this kit include a head gasket and valve stem seals?

A: Yes. As a full gasket and upper repair kit, it includes the cylinder head gasket (multi-layer steel) and valve stem seals. It also includes all necessary intake/exhaust manifold gaskets, valve cover gasket, and other upper engine seals required for a complete top-end rebuild.
