The FAW 1005071-81DB flywheel bolt is a critical high-stress fastener built for FAW commercial heavy-duty trucks. Manufactured under original OEM specifications, this genuine bolt ensures that the flywheel remains locked firmly to the crankshaft flange, preventing catastrophic drivetrain separation under heavy hauling conditions.
💪Reliable Fastening for Heavy-Duty Diesels
Maintaining proper clamp load on rotating engine components is essential for safety and reliability. The 1005071-81DB flywheel bolt delivers dependable performance:
- High Tensile Strength: Engineered to handle severe rotational shear forces and high-torque engine output without stretching or snapping.
- Seamless OEM Interchangeability: Perfectly replaces older material numbers like 1005071-81D and S1005071-81D without requiring modifications.
- Corrosion & Heat Resistance: Specially treated alloy steel resists fatigue and thermal degradation inside the enclosed bellhousing environment.
