Warning! Dust from clutch component wear may contain asbestos, which is harmful to health. DO NOT blow it off with compressed air and try NOT to inhale it. DO NOT use gasoline or mineral solvents to wash off the dust, there are special cleaners for this, methylated spirits will also work.
Removal
1. On these models, it is necessary to remove the power unit from the vehicle, and then, on a workbench, separate the transmission from the engine (refer to Chapter Engine repair).
2. Before removing the clutch, mark the basket and flywheel with paint or a marker.
3a. Loosen the basket bolts in a diagonal sequence...
3b....turning them half a turn per set so that the bolts can be loosened by hand.
4. Press the basket off the mounting pins and remove the friction disc, noting its orientation.
Note: Given the length and complexity of the procedure for removing and installing clutch components, it is recommended to replace the friction disc, basket and release bearing, even if only one of these components is worn.
Inspection
1. Before cleaning the clutch components, read the Warning at the beginning of this Section. Remove all dust using a clean, dry cloth.
2. Inspect the friction disc linings for damage, signs of wear and oil stains. If the friction lining is cracked, burnt, scratched or otherwise damaged, contaminated with oil or grease (shiny black spots), replace the friction disc. Check the rivet setting depth; if it is 0.5 mm or less, the friction disc must also be replaced.
3. If the friction linings are still serviceable, check that the disc hub grooves are not worn, the damper springs are in good condition and securely fastened, and that all rivets are in place. If any of the above damage is found, replace the friction disc.
4. If the friction lining is contaminated with oil, it may be caused by a leak at the crankshaft seal, transmission input shaft seal or oil pan/cylinder block joint. Before installing a new friction disc, replace the seal or gasket (see the relevant section of Chapter Engine repair or Transmission).
5. Inspect the basket for signs of wear and damage. Shake it to check for broken rivets and diaphragm spring support rings. Check that the plates that secure the pressure plate to the clutch basket do not show signs of overheating (bright yellow or blue spots). If the diaphragm spring is worn or damaged, or if its pressure has weakened, replace the basket (refer to the accompanying illustration).
6. Inspect the machined surfaces of the pressure plate and flywheel; they must be clean, perfectly flat and smooth. If one of the components has either changed colour due to overheating or cracked, it should be replaced. Minor damage of this nature can sometimes be ground off using sandpaper.
7. Check that the release bearing rotates smoothly and easily, without noise or jerking. Also check that its surface is smooth and free of cracks, pitting or worn areas. If there is any doubt about its condition, replace the bearing.
Installation
1. When reassembling, make sure the flywheel and pressure plate running surfaces are clean and smooth. Use solvent to remove protective grease from new components.

2. Install the friction disc so that the protruding part of its hub is directed away from the flywheel. If necessary, fix the friction disc in the working position using the clutch centering tool (refer to the accompanying illustration).
3. Install the pressure plate assembly onto the pins (refer to the accompanying illustration), aligning the marks made during removal. Insert the pressure plate bolts, but tighten them only by hand for now so that the friction plate can still move.
4. The friction disc must be centered so that when the transmission is installed, its input shaft can pass through the disc hub.
5. To do this, insert a screwdriver or any long rod through the friction disk into the recess in the end of the crankshaft and move the disk in the desired direction until the crankshaft recess is exactly in the center of the disk hub. Alternatively, you can use a special centering tool or make a homemade tool from a metal or wooden pin close in diameter to the recess in the crankshaft and having a thickening in the place of contact with the hub of the friction disk corresponding to the diameter of the disk hole.
Note: Renault clutch kits are supplied with a special centering tube.
6. After the friction disc is centered, tighten the pressure plate bolts evenly and in a diagonal sequence to the torque specified in the Specifications. Remove the centering tool.
7. Apply a small amount of molybdenum grease to the contact surfaces of the release bearing, guide bushing and fork (Renault recommends Molykote BR2).
Caution: Do not apply too much grease, as excess grease may come into contact with the friction disc linings.
8. Install the transmission onto the engine, then install the power unit into the vehicle as described in Chapter Engine repair.
