FAQ

Q: Is this plastic crankshaft compatible with all Komatsu 6D105 engines?
A: Yes, it is designed for standard 6D105 diesel engines used in excavators and farm equipment. However, we recommend verifying your engine serial number and crankshaft dimensions (e.g., stroke length, journal size) to ensure exact fitment, as some variants may exist.

Q: How does a plastic crankshaft compare to a steel one in terms of durability?
A: Plastic crankshafts are lighter and resist rust, making them suitable for low-to-moderate load applications like certain farm and construction equipment. They reduce engine weight and vibration but may not withstand extreme torque as steel. For heavy-duty excavator use, confirm with your mechanic that the plastic type meets your engine’s stress requirements.

Q: What installation tips should I follow for this crankshaft?
A: Ensure the engine block and bearings are clean and undamaged. Lubricate the crankshaft journals with engine oil before installation. Torque all connecting rod and main bearing bolts to Komatsu 6D105 specifications (typically 80-100 Nm, but check your manual). After installation, rotate the engine manually to check for smooth movement before starting.
