Replace the shut-off lever bushings
Clutch release lever bushings, which are the bearing element of the lever shaft, can be replaced without removing the gearbox.
In order to remove the bushings, the pressure assembly of the clutch should be disassembled., so that the protrusions on the sleeves fit into the cutouts of the housing. The inner surface of the sleeves must be coated with a paste with molybdenum disulphide.
