Which are the common clutch problem and defects?

Clutch is one of the most used components in a vehicle. 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 problem 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. It may be caused by the following factors:

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

2. Clutch Problem:

Clutch drag or spin & inability to engage a gear when you press the pedal, resulting in a jammed driven plate. This is caused by the following:

  • 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 Clutch Problem and Defects:

Judder & vibrations resulting in a sudden forward jump of the vehicle is caused by the following factors:

  • Greasy facing or friction surfaces
  • Misalignment of gear box caused by distortion of the clutch housing
  • Loose or badly worn linings
  • Loose or protruding rivets
  • Too much backlash in universal joints or rear axle
  • Flywheel loose on crankshaft flange
  • Estrangement of engine tie bar
  • Uneven wear of friction surfaces
  • Defective engine mountings allowing excessive torque reaction movement
  •  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 Problem 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 problem & defects.

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