DDE EA4710307005 | Genuine Detroit Diesel® Clutch Flywheel Assembly

It allows the engine to stay running while the driver engages or disengages the transmission.

2. Provides Friction Surface

The clutch disc presses against the flywheel to transmit engine power to the transmission.

3. Helps Start the Vehicle

The flywheel has gear teeth around its edge that the starter motor engages with to crank the engine.

4. Reduces Vibration

Its weight stabilizes engine rotation for smoother performance.

5. Allows Shifting

When the clutch pedal is pressed, the assembly disconnects engine power so gears can be shifted smoothly.

1. Vibrations (Chatter or Shudder)

• Shaking or shudder when releasing the clutch

• Jerky starts from a stop

• Often caused by warped or uneven flywheel surfaces

2. Slipping Clutch

• Engine revs increase but vehicle speed doesn’t

• Happens when the flywheel surface is worn, glazed, or burnt

3. Burning Smell

• Sharp, burnt smell (similar to burnt toast)

• Caused by excessive friction between the clutch disc and flywheel

• Hard to get into gear

• Grinding when shifting

• Caused by incomplete clutch disengagement due to flywheel damage

5. Clutch Pedal Vibrates or Pulses

• Pedal feels shaky when pressed

• A warped flywheel causes inconsistent pressure and vibration

6. Rattling or Knocking Noises

• Noises when idling or when the clutch pedal is pressed

• Loose flywheel bolts or cracked flywheel can cause this

7. Poor Acceleration

• Vehicle feels weak or sluggish

• Caused by slipping or uneven contact with the clutch disc

8. Starter Problems

• Grinding noise when starting the engine

• Worn or damaged flywheel teeth prevent the starter from engaging properly
