Clutch: Testing and Inspection

Checking clutch pedal (end position)

Clutch pedal: checking play and pedal end position

Checking clutch free play

The clutch master cylinder has an inner stop. The push rod and the clutch pedal are always pressed against this stop by the clutch power spring. Due to the automatic hydraulic adjustment of the clutch, it is not possible to determine the clutch play by checking at the clutch pedal.

Clutch: Checking pedal end position (pedal return/return force)

Information
This work step only needs to be performed in the course of maintenance.

The pedal must not give way during the operation.

If it gives way, the fault is in the clutch power spring or in the pedals.

- Check that the pedal is in end position by pulling at the pedal (without the use of force) towards the driver's seat.

The clutch push rod and the clutch power spring are not adjustable. The clutch power spring has two functions, namely to provide pedal force assistance and to return the pedal. The following are some of the points which are requirements for perfect clutch operation:
Correct bleeding of the clutch hydraulic system.
No leaks in the hydraulic system
Pedal return to the starting position
Installation position of the pedals corresponds to the standard condition
