What is the FAW   Engine Aseembly-Flywheel Group

  • 1. FAW WP13.550E501 Flywheel Group: Power Transfer Hub
    The Flywheel Group is a fundamental rotating assembly within the FAW WP13.550E501 Engine Assembly. Mounted directly to the engine crankshaft, it serves critical functions: storing rotational inertia for smoother engine operation, providing the mounting surface for the clutch assembly (in manual transmissions), and featuring the Flywheel Ring Gear for reliable starter motor engagement. This precisely balanced group ensures efficient power transfer from the engine to the drivetrain.
  • 2. Core Rotational Components: Bearing & Ring Gear
    At the heart of rotational support is the Deep Groove Ball Bearing, engineered to handle significant radial loads and ensure smooth rotation where required within the flywheel assembly or its housing. Complementing this is the crucial Flywheel Ring Gear, a hardened steel ring with precisely cut teeth press-fit onto the flywheel’s circumference. This gear interfaces directly with the starter motor’s pinion gear to crank the WP13.550E501 engine during ignition.
  • 3. Secure Positioning & Friction Control
    Precise location and controlled friction are vital. The Elastic Ring for Bore provides a resilient, often anti-rotation or damping interface within a bore, preventing unwanted movement or wear. Wave Spring Washers deliver consistent axial load and compensate for thermal expansion/contraction or minor component tolerances at bolted joints, maintaining critical clamping force and preventing bolt loosening under the engine’s high vibration.
  • 4. Robust Fastening System
    The flywheel’s secure attachment relies on multiple specialized fasteners:
    * Flywheel Bolt: High-strength bolts specifically designed to withstand immense shear forces and torque, directly clamping the flywheel to the crankshaft flange.
    * Double Stud: Provides stable, threaded mounting points for ancillary components bracketed to the flywheel housing or engine block.
    * Type 1 Hexagon Nut: Used with studs or bolts, this standard nut (typically conforming to ISO or DIN standards) ensures secure fastening of components connected via the Double Stud.
  • 5. Specialized Engagement & Alignment
    The Free Wheel (often an overrunning clutch component within the starter drive system) allows the starter pinion to engage the Flywheel Ring Gear for cranking but disengages immediately once the engine starts, protecting the starter motor from overspeed damage. Precision alignment is guaranteed by the Cylindrical Pin, a simple yet critical dowel pin ensuring accurate positioning of mating components within the flywheel assembly or between the flywheel and crankshaft.
