Warning: Dust created by clutch wear and deposited on the clutch components may contain asbestos, which Is a health hazard. DO NOT blow it out with compressed air, or inhale any of it. DO NOT use petrol or petroleum-based solvents to clean off the dust. Brake system cleaner or methylated spirit should be used to flush the dust Into a suitable receptacle. After the clutch components are wiped clean with rags, dispose of the confam/nafed rags and cleaner In a sealed, marked container. Note: Although some friction materials may no longer contain asbestos, it is safest to assume that they DO. and to take precautions accordingly.
Removal 1 Unless the complete engine/transmission is to be removed from the car and separated for major overhaul (see Chapter 2D), Ihe clutch can be reached by removing the transmission as descnbed in Chapter 7A, 2 Before disturbing the clutch, use chalk or a marker pen to mark the relationship of the pressure plate assembly to the flywheel. 3 Working In a diagonal sequence, slacken the pressure plate bolts by half a turn at a time, until spring pressure Is released and the bolls can be unscrewed by hand (see Illustration). 4 Prise the pressure piate assembly off its locating dowels, and collect the friction plate, noting which way round the friction plate is fitted (see Illustration).
Inspection Note: Due to the amount of work necessary to remove and refit clutch components, It is usually considered good practice to renew the clutch friction plate, pressure plate assembly and release bearing as a matched set. even if only one of these is actually worn enough to require renewal. It Is also worth considering the renewal of the clutch components on a preventative basis if the engine and/or
6.4 Removing the clutch slave cylinder from the transmission fransmj'ss/on have been removed for some other reason. 5 Separate the pressure plate and friction plate and place them on the bench. 6 When cleaning clutch components, read first the warning at the beginning of this Section; remove dust using a clean, dry cloth, and working in a well-ventilated atmosphere. 7 Check the friction plats facings for signs Of wear, damage or oil contamination. If the friction material is cracked, burnt, scored or damaged, or if It is contaminated with oil or grease (shown by shiny black patches), the friction plate must be renewed. 8 If tho friction material Is still serviceable, check that the centre boss splines are unworn, that the torsion springs are In good condition and securely fastened, and that all the rivets are tight. If any wear or damage is found, the friction plate must be renewed. 9 If the friction material is fouled with oil, this must be duo to an oil leak from the crankshaft rear (left-hand) oil seal, from the sump-to-cytinder block joint, or from the transmission Input shaft. Renew tha soal or repair the Joint, as appropriate, before Installing the new friction plate. 10 Check tha pressure plate assembly for obvious signs of wear or damage; shake it to check for looss rivets or worn or damaged fulcrum rings, and check thai the drive straps securing the pressure plate to the cover do not show signs (such as a deep yellow or blue discoloration) of overheating. If the diaphragm spring is worn or damaged, or if its pressure is In any way suspect, the pressure plate assembly should be renewed.

4 Manual transmission overhaul -general Infomtatlon
Overhauling a manual transmission is a difficult and Involved Job for the DIY home mechanic. In addition to dismantling and reassembling many small parts, clearances must be precisely measured and, if necessary, changed by selecting shims and spacers. Internal transmission components are also often difficult to obtain, and in many Instances, extremely expensive. Because of this, If the transmission develops a fault or becomes noisy. Ihe best course of action is to have the unit overhauled by a specialist repairer, or to obtain an exchange reconditioned unit. Nevertheless, it is not impossible for the more experienced mechanic to overhaul the transmission, provided the special tools are available, and the Job is done in a deliberate step-by-step manner, so that nothing is overlooked.
The tools necessary for an overhaul include internal and external clrclip pliers, bearing pullers, a slide hammer, a sat of pin punches, a dial test Indicator, and possibly a hydraulic press. In addition, a large, sturdy workbench 8od a vice will be required. During dismantling o1 the transmission, make careful notes of how each component

fitted, to make reassembly easier and more accurate. Before dismantling the transmission, it will help if you have some idea what area is malfunctioning. Certain problems can be closely related to specific areas In the transmission, which can make component examination and replacement easier. Refer to the Fault Finding Section at the end of this manual for more Information.
5 Reversing light switch -testing, removal and refitting ||
Testing 1 The reversing light circuit is controlled by a plunger-type switch screwed into the front of the transmission casing. If a fault develops, first ensure that Ihe circuit fuse has not blown. 2 To test the switch, disconnect the wiring connector, and use a multimeter (set to the resistance function) or a battery-and-bulb test circuit to check that there is continuity between the switch terminals only when reverse gear is selected. If this is not the case, and there are no obvious breaks or other damage to the wires, the switch is faulty, and must be renewed.
Removal 3 Access to the reversing light switch Is best achieved from under the vehicle. Apply the handbrake then jack up Ihe front of the vehicle and support on axle stands (see Jacking and vehicle support). 4 Disconnect the wiring connector, then unscrew It from the transmission casing.
Refitting 5 Refit the switch and tighten securely. 6 Reconnect the wiring then lower the vehicle to the ground.

1 General information
Power is transmitted from the differential to
Ihe
roadwheels by the driveshafts. via inboard and outboard constant velocity (CV) joints (we illustrations). An intermediate drive shaft, with its own support bearing is fitted between the gearbox output and right-hand drive shafts on turbo desei models (see Illustration overleaf). This layout has the effect of equalising driveshaft angles at sll suspension positions and reduces tfveshaft flexing, which improves directional stability, particularly under acceleration. The outer Rzeppa type CV joints allow smooth transmission of drive to the wheels at all steering and suspension angles. Drive Is transmitted by means of a number of radially static steel balls that run In grooves between
the two halves of the joint. The type of inboard CV joint fitted is model dependant. Those fitted to all except the turbo diesel models are of the plunge-cup type; drive is transmitted across the joint by means of three rollers, mounted on the driveshaft in a tripod arrangement, that are radially static but are free to slide in the grooved plunge cup.
The inboard CV joints fitted to turbo diesel models are of the Rzeppa type, similar to those at the outboard end of the driveshaft. On the right-hand driveshafl, the joint is bolted directly to the end of the intermediate driveshaft flange. On the left-hand driveshaft, the joint is bolted to the transmission output shaft flange.
