Removal
1. Remove the ground cable from the battery.
Warning: If your radio has an anti-theft code, make sure you have the connection codes before disconnecting the battery.
Caution! On models from 1993 onwards, the airbag system is disabled if the battery is disconnected for an extended period of time. If the airbag warning light comes on and remains on after the battery is reconnected, contact a specialist workshop to restore the system to working order.
2. Remove the gearbox.
3. Remove the clutch release fork from the ball stud, then remove the release bearing from the clutch release fork.
Examination
1. Check the release bearing, which should rotate easily, evenly and quietly. The working surface of the bearing, which acts on the pressure spring, should be smooth, without cracks, local corrosion or wear.
Installation
1. Apply a thin coat of high temperature grease to the inside surface of the release bearing, the input shaft splines and the release bearing guide sleeve.
2. Apply a thin coat of high temperature grease to the areas of the release fork that contact the release bearing, ball stud and pushrod.
3. Install the release bearing onto the clutch release fork.
4. Install the release bearing onto the guide sleeve at the front of the gearbox. At the same time, pass the clutch release fork through the hole in the clutch housing. Install the clutch release fork onto the stud with the ball end until it is secured.
5. Apply a thin coat of high temperature grease to the front side of the release bearing that contacts the pressure plate diaphragm spring.
6. Further installation is carried out in the reverse order of removal.
