How to protect clutches from Grease Contamination

How to protect clutches from Grease Contamination

Why do we need grease ?

 

Grease is required for lubrication of moving, rotating and articulating parts in every automobile to prevent abnormal wear and tear and also ensures there is smooth sliding of the clutch disc on the main drive shaft.  It helps in increasing the overall life of spares.

 

What is grease contamination in a Clutch Disc (Friction material getting contaminated)  ?

 

If Excessive grease is used upon installation (Bearing Slide and/or shaft splines) , pressure plate surface and flywheel surface can become slippery which will affect the performance of the product.

 

3 Major wrong Market practices

 

  • usage of incorrect type of grease
  • usage of incorrect amount of grease
  • Incorrect components are lubricated with grease

 

Usage of incorrect type of grease

 

Always use the correct, high temperature grease suitable for use in clutch environments!

Most of the Valeo clutch kits comes with  a sachet of grease. If the sachet of grease is not available in the packaging use only a high pressure, high temperature grease, such as BR2 type grease

Copper based grease is unsuitable for use due to its low viscosity and melting temperatures.

 

Usage of incorrect amount of grease

Only a thin coating of grease is required. The parts require lubrication.

Incorrect components are lubricated with grease

DO NOT APPLY GREASE DIRECTLY TO THE SPLINES ON THE DRIVE PLATE HUB. The grease will be pushed out from the splines during installation of the input shaft allowing it to accumulate on the outside of the hub.

 

Lubricate: The release bearing guide. The fork bearings. The primary shaft

pilot bearing or bushing.

Take the time to clean the gearbox thoroughly before installing a clutch and check the surrounding area (including gearbox) for any damaged or worn components.
