Clutch Pedal Assembly: Adjustments

NOTE: The following items are essential requirements for smooth clutch operation and must therefore be observed whenever the pedal is adjusted:
^ Correct bleeding of clutch hydraulics.
^ Tightness of hydraulic system.
^ Correct setting of boost spring.
^ Pedal travel limited by correctly set floorboard stop.
^ Fitting position of pedals according to standard specification.

Checking the Pedal Return (return force)
- With the pedal in home position, pull pedal back with a force of 30 N min. (using a spring balance). The pedal must not yield, If it does (= return force insufficient), the boost spring preload must be reduced or set to a dimension of 6 mm.

Boost Spring Adjustment





- Adjusting the boost spring (dimension A = 6 mm).





- Adjustment is made by rotating the hex socket head bolt. The clearance between screw and pivot must be 6 mm.

Checking the Pedal Travel





Dimension B = 145 mm

- When measured in the center of the pedal, the pedal travel must be 145 mm + 10. If required, adjust or limit the pedal travel at the floorboard stop.

Clutch Free Play





- The clutch master cylinder is provided with an internal stop. The boost spring always forces the pushrod and hence the clutch pedal against this stop. Due to the fact that any free play is automatically taken up hydraulically the free play of the clutch cannot be checked at the clutch pedal.
