Causes of clutch slip

- Contaminated Clutch Disc [Slip]

 Causes 



Excessive Application of Grease on the Teeth of the Disc

One of the most common causes of clutch slippage is the over-application of grease on the teeth of the clutch disc.

While lubrication is necessary to reduce friction and ensure smooth operation,

applying too much grease can lead to contamination of the clutch surface.

When excess grease spreads to areas it shouldn't, such as the friction surfaces,

it reduces the grip between the clutch disc and the flywheel, causing slippage.

This slippage can result in a loss of power transmission from the engine to the drivetrain,

leading to decreased vehicle performance and potential long-term damage to the clutch system.

Oil Leak from the Engine or Gearbox

Oil leakage from the engine or gearbox is another significant cause of clutch disc contamination.

Over time, seals or gaskets in the engine or gearbox can deteriorate, leading to oil seepage.

If this oil makes its way onto the clutch disc, it can create a slick,

lubricated surface that interferes with the normal friction required for the clutch to engage properly.

The result is clutch slippage, where the clutch disc fails to transmit full power due to the presence of oil on its surface.

Prolonged exposure to oil can also degrade the clutch material, necessitating early replacement.

 Maintenance & Precaution 

Replace the Clutch Disc

Once the clutch disc becomes contaminated—whether due to excessive grease or an oil leak—cleaning may not be sufficient to restore proper functionality.

In most cases, the best solution is to replace the clutch disc entirely.

This ensures that the new disc is free from contamination and can perform optimally,

providing the necessary friction for efficient power transfer.

Check and Remove Contaminants

It is important to regularly inspect the clutch system for contaminants.

This includes checking for excessive grease application or any signs of oil leakage from nearby components,

such as the engine or gearbox. If contamination is found early, cleaning the affected parts may prevent further damage.

Additionally, it is crucial to address the root cause of any oil leak to avoid future recurrence.

Apply the Proper Amount of Grease on the Teeth of the Disc

While lubrication is essential, it is important to apply the correct amount of grease.

Over-lubricating the clutch disc or its components can lead to slippage,

while under-lubrication can cause wear and tear due to excessive friction.

Always refer to the manufacturer's guidelines for the appropriate type and amount of grease, ensuring

it is applied only to the necessary areas—such as the splines—without spreading to the friction surfaces.
