Checking Clutch Plate For Wear

Information 

• The clutch lining does not wear linearly over the service life of the clutch. 
• Due to the settling behavior of the clutch lining, more wear occurs at the beginning. 
• Pad thickness wear will decrease as mileage increases. 

Information 

Pad thickness measurement must only be done on the flanged side of the rivet head.

1. Place a commercially available depth gauge on the clutch lining -1-  and measure the distance to the rivet head.

The wear dimension -X-  measures 0.3 mm. If a smaller value is measured, the clutch drive plate must be replaced. When new the measured value is more than 1mm.
