FAQ

Q1: Is this kit a direct fit for my Komatsu PC400-7 with a 6D125 engine?
Yes, this kit is designed as a direct replacement for the Komatsu 6D125 and SAA6D125-7 engines. However, we strongly recommend verifying your engine serial number and current bore size to ensure compatibility, especially if your engine has been previously rebored to an oversize.

Q2: What is included in the “Overhaul Repair Set”?
This comprehensive set includes a full piston set (with rings and pins), a complete gasket kit (including head gasket, valve cover gasket, oil pan gasket, etc.), a valve set (intake and exhaust valves, guides, and seals), and a full bearing set (main bearings, connecting rod bearings, and thrust washers). Please contact us for a detailed parts list.

Q3: What is the recommended installation procedure and break-in period?
Professional installation by a qualified diesel mechanic is highly recommended. All surfaces must be meticulously cleaned. Torque all bolts to the manufacturer’s specifications using a calibrated torque wrench. After installation, a proper break-in period is crucial: avoid heavy loads for the first 50 hours, and perform an oil and filter change after the initial break-in period to remove any wear particles.
