Mercedes-Benz W176 A220 CDI (OM651) Automatic Flexplate/Flywheel | Genuine OEM

Description

For the Mercedes-Benz W176 (A-Class/CLA/GLA) with the OM651 diesel engine and automatic transmission, the “flywheel” is technically a flexplate. Because it connects the high-torque diesel engine to the automatic transmission’s torque converter, any wear—such as cracked bolt holes or damaged ring gear teeth—will lead to severe vibrations, rattling noises at idle, or transmission engagement issues.

If you are currently performing an engine or transmission swap on your A220d, or if your vehicle is producing a rhythmic “tapping” or “clunking” sound from the bell housing, replacing the flexplate with a workshop-vetted original unit is essential for drivetrain longevity.

• Torque-Load Engineered: Designed to handle the high-torque output of the OM651 diesel engine, preventing the structural fatigue and cracking common in lower-quality aftermarket flexplates.

• Precision-Balanced: Factory-balanced to eliminate harmonic vibrations, protecting your transmission’s input shaft bearings and oil seal.

• Condition: Premium workshop-vetted original component; verified for zero stress-cracks around the center mounting hub and flawless teeth on the starter ring gear.

Signs Your Flexplate Needs Replacement:

• Rattling/Tapping Noise: A metallic rattling sound coming from the area where the engine meets the transmission, especially noticeable at idle.

• Shuddering on Acceleration: A vibration that feels like a drivetrain issue but is actually the flexplate flexing under load because of structural fatigue.

• Starter Engagement Issues: Grinding noises during start-up, indicating that the starter ring gear teeth (welded to the flexplate) are damaged.

• Transmission Leaks: Persistent leaks from the front transmission seal can sometimes be caused by a “wobbling” flexplate putting uneven pressure on the transmission input shaft.

Workshop Pro-Tip: When replacing the flexplate, always use new torque-to-yield (stretch) bolts to secure it to the crankshaft. Never reuse the old bolts, as they are designed to be tightened to a specific stretch point; reusing them can lead to them backing out, which would cause catastrophic damage to both your engine and transmission. Also, check the engine-to-transmission alignment dowels; if these are missing, the flexplate will vibrate and fail again in a very short time.
