Customized Nitrided Crankshaft For HO7C Diesel Engine

This HO7C crankshaft is a high-quality aftermarket replacement part designed for HO7C inline 6-cylinder diesel engines, widely fitted on Hino trucks, buses and heavy construction machinery.
It is made of high-strength forged steel or nodular cast iron. All main journals and connecting rod journals are precision ground and nitrided to increase surface hardness and wear resistance. Fillet rolling treatment improves fatigue resistance to avoid cracking under long-time cyclic heavy loads.
Every crankshaft passes dynamic balance testing and full dimensional inspection before delivery, which reduces engine vibration and ensures stable long-term operation.
Perfect for engine rebuild, repair shop maintenance and bulk wholesale.

✅ Nitriding surface for excellent wear resistance
✅ High fatigue strength to sustain continuous heavy load
✅ Strict QC control, low failure rate
✅ Direct fit, easy installation
