Which Are The Common Clutch Problems And Defects?

The Clutch is one of the most used components in a vehicle. But unfortunately, it wears out due to constant usage and friction and develops problems. Hence, its performance deteriorates. So, let’s look at some of the most common clutch problems and defects in a vehicle.

1. Clutch slippage: Common Clutch Problems and Defects

The clutch slips at the mating surfaces due to its inadequate frictional torque or engine power. The following factors may cause it:

  • First, worn-out linings of the clutch plate.
  • Greasy friction surface or clutch linings.
  • Locked or bound pedal travel
  • Incorrect pedal adjustments such as free-play and travel on the clutch pedal or release bearing
  • Weak or broken pressure springs
  • The burnt or scored surface of the flywheel or pressure plate.
  • Floorboard or carpet incorrectly fitted.

2. Clutch Problems:

Clutch drag or spin & inability to engage a gear when you press the pedal, resulting in a jammed driven plate. The following may cause it:

  • Misalignment resulted due to the weight of the hanging gearbox on the spindle
  • Broken or greasy clutch and pressure plate or flywheel
  • Incorrect pedal adjustment – insufficient actual pedal travel, excessive free-play of the pedal or slave cylinder push rod
  • Locked drive plate
  • Broken or incorrectly adjusted release levers
  • Damaged clutch cover, driven plate or friction, or pressure plate
  • Clutch release bearing defective

3. Common Problems and Defects:

The following factors cause judder & vibrations resulting in a sudden forward jump of the vehicle:

  • Greasy facing or friction surfaces
  • The distortion of the clutch housing causes the misalignment of the gearbox caused by
  • Loose or badly worn linings
  • Loose or protruding rivets
  • Too much backlash in universal joints or rear axle
  • Flywheel loose on the crankshaft flange
  • The estrangement of the engine tie bar
  • Uneven wear of friction surfaces
  • Defective engine mountings allow excessive torque reaction movement
  •  A bent splined shaft or driven plate
  • Defective release mechanism

4. Clutch Problem: Snatch or Fierceness Caused By The Following:

  • Misalignment
  • Locked pedal mechanism
  • Greasy friction surfaces
  • Worn out surfaces

5. Tick or Knock Caused By The Following:

  • Worn out pilot bearings
  • Worn out hub splines due to misalignment

6. Clutch Problems and Defects: Rattle In The Clutch Is Caused By:

  • Worn out release mechanism
  • Damaged driven plate
  • Loose release bearings
  • Worn out transmission bearings
  • Worn out or bent splined shaft
  • Excessive backlash in transmission also causes clutch problems & defects.

Eaton and Spicer are some of the popular manufacturers of clutch systems in the world.
