FAQ

Q1: Is this gasket kit a direct fit for my Komatsu PC400-6 with a 6D125 engine?

Yes, this kit is specifically designed for the Komatsu 6D125 engine as used in the PC400-6 excavator. It is a direct replacement. However, we strongly recommend verifying your engine serial number (e.g., 6D125-xxxxx) to ensure compatibility with your specific engine variant, as minor design changes occurred during production.

Q2: What is the typical installation time for this full gasket kit?

Installation time depends on the mechanic’s experience. A professional diesel technician can typically complete a full engine overhaul, including replacing all gaskets in this kit, within 8-12 hours. We recommend following the official Komatsu service manual for torque specifications and tightening sequences to ensure a proper seal.

Q3: What maintenance steps should I take after installing this gasket kit?

After installation, it is critical to perform a break-in procedure. This includes running the engine at low idle for 5-10 minutes, checking for leaks, and then re-torquing the cylinder head bolts after the first heat cycle (allow engine to cool completely). Replace all fluids (oil, coolant) and filters. Monitor the engine for the first 50 hours of operation for any signs of leakage or abnormal temperatures.
