Checking the technical condition of the clutch (Granta 2190)

Clutch in engaged position (with the pedal released) should not "slip" and transmit torque from the engine to the transmission without loss, and when the clutch pedal is pressed, completely disconnect the transmission from the engine. The clutch engagement should be smooth, without jerks.

To complete the work you will need a ruler or tape measure.

Sequence of execution

1. Check the working stroke of the clutch pedal and adjust it if necessary (see "Clutch release drive - adjustment").

2. With the engine not running, press the clutch pedal several times. We make sure that there are no jams in the clutch release drive mechanism, and that there are no creaks, knocks or other extraneous noises.

3. Using a ruler or tape measure, measure the distance from the floor to the outer surface of the clutch pedal.

4. Press the pedal all the way to the floor and repeat the measurements.

Recommendation. If the full pedal travel increases to 146 mm, adjust the clutch release drive (see "Clutch release drive - adjustment").

5. Start the engine. If you hear a whining sound coming from the clutch housing, the clutch release bearing is most likely worn out. After disconnecting the cable from the clutch release fork (see "Clutch cable - replacement") and turning the fork slightly clockwise, we move the release bearing away from the diaphragm spring. If the release bearing is faulty. the sound will disappear.

6. With the engine running, press the clutch pedal all the way down and engage the gear. The switch should be easy to turn on, without any crackling or crunching sounds. If you hear a crackling noise when engaging gears and it is difficult to disengage them, the clutch is not disengaging completely.

7. With the engine running and first gear engaged, gradually release the clutch pedal. we check the smoothness of the clutch engagement, the absence of jerks or extraneous sounds when starting off.

8. While driving in third or fourth gear, sharply press the gas pedal. If the crankshaft speed increases quickly, and the car accelerates sluggishly, then the clutch is slipping. This is also indicated by the appearance of a burning smell in the cabin, emitted by the very hot friction linings of the driven disk.

If the above signs of malfunction are not detected during the clutch diagnostics, the clutch is in good technical condition.
