FAQ

Q1: How do I confirm this bolt is the correct part for my Komatsu PC300-8 excavator?
A1: The primary identifier is your engine model, which must be the Komatsu 6D114. We recommend checking your engine’s serial number plate and consulting the official service parts catalog. You can also provide us with your old bolt or its OEM number for verification.

Q2: What is the recommended torque specification and installation procedure for this cylinder head bolt?
A2: Cylinder head bolts are critical torque-to-yield (TTY) fasteners in most modern diesel engines. Always follow the exact, multi-step torque sequence and angle specification outlined in the official Komatsu 6D114 workshop manual. Using a calibrated torque wrench and proper lubrication as specified is mandatory to achieve the correct clamping force and prevent engine damage.
