Premium Material for Durability and Performance
This flywheel is precision-cast from high-grade nodular iron (ductile iron, e.g., GGG70), a material selected for its superior mechanical properties over standard gray iron. Nodular iron provides an exceptional combination of high tensile strength, excellent fatigue resistance, and outstanding impact toughness. This is crucial for withstanding the high torque output and constant engagement cycles of heavy-duty diesel engines in BENZ and MAN trucks. The material's excellent thermal stability prevents warping and heat spotting, ensuring consistent clutch engagement and preventing chatter, while its inherent vibration-damping characteristics contribute to smoother overall drivetrain operation.
Precision Engineering and Manufacturing Process
The manufacturing process begins with a controlled casting to create a dense, homogeneous structure free from internal defects. This is followed by multi-stage CNC machining on all critical functional surfaces. Operations include precision turning of the friction surface to ensure perfect flatness, boring of the crankshaft pilot bore for exact alignment, and machining of the mounting flange. The starter ring gear is heat-treated for maximum durability and precisely fitted to guarantee flawless engagement. A final, critical step is dynamic balancing, where each flywheel is balanced to a high standard to eliminate vibrations that can damage crankshaft main bearings and transmission input shafts, thereby ensuring smooth operation and protecting the entire powertrain.
Direct Application for Reliable Performance
This flywheel is designed as a direct-fit replacement for specific engine models in BENZ (e.g., Actros, Arocs) and MAN (e.g., TGS, TGX) trucks. It is an integral part of the clutch assembly, providing the precise friction surface for the clutch disc and facilitating the connection between the engine and transmission. This high-quality product is the definitive solution for repairs necessitated by wear, heat damage, or surface cracking on the original unit. Its reliable performance is vital for smooth gear shifts, efficient power transmission, and the prevention of costly secondary damage, making it an essential component for maximizing fleet uptime and operational efficiency.
Choose this European Truck Flywheel for the durability, precision, and reliability that BENZ and MAN vehicles are engineered for, ensuring your fleet remains on the road and productive.



Why are we called OEM experts in Exhaust Manifolds  | 
We develop over 100 different types of exhaust manifolds every year  | 
||||||
Dandong Pengxin  Production Process for Exhaust Manifold  | 
Drawing Preparation: The Foundation of Precision,3D Scanning & Drafting: Our professional engineers use advanced scanners to convert samples into 2D/3D drawings (7–10 days).  | 
||||||
Pattern & Sample Development: Where Time Invested Pays Off  | 
Complexity: Exhaust manifolds often require 3–5 sets of metal patterns (vs. 1 set for simpler castings).Lead Time: 35–40 days for multi-cavity patterns; 25–30 days for simpler designs.  | 
||||||
Initial Orders & Batch Production: Scaling Responsibly  | 
Machine Allocation: One manifold order may occupy 2–3 molding machines. Our 16-machine facility prioritizes urgent orders and collaborates with partner foundries for auxiliary cores.  | 
||||||
How Investors Can Mitigate Delays  | 
Allocate 8–12 weeks for pattern/sample development. Compressing this risks quality failures. First batches take 20–30% longer due to process fine-tuning. Post-approval, lead times stabilize.  |
