Before performing any service that requires removal of the clutch slave cylinder, the master cylinder and pushrod must be disconnected from the clutch pedal to avoid permanent damage to the master cylinder assembly if the clutch pedal is depressed while the clutch slave cylinder is disconnected. For 1983-84 models, the clutch hydraulic system is serviced as a complete unit, which has been bled of air and filled with fluid, as individual components are not available separately. For 1985 models, disconnect the negative battery cable, remove the transmission assembly, take off the clutch housing-to-transmission retaining nuts, and remove the housing assembly before taking out the clutch slave cylinder from the transmission input shaft. To install, fit the clutch slave cylinder over the transmission input shaft with the tower portion facing the transmission, install the clutch housing to the transmission ensuring proper location of the clutch slave cylinder, install the transmission, and bleed the hydraulic system. For 1986-90 models, start by disconnecting the negative battery cable and the coupling at the transmission using the appropriate tool, then remove the transmission assembly, the clutch slave cylinder-to-transmission retaining bolts, and the clutch slave cylinder from the transmission input shaft. To install, fit the clutch slave cylinder over the transmission input shaft with the bleed screws and coupling facing the left side, install the retaining bolts with specified torque, reinstall the transmission, reconnect the coupling, bleed the system, and reconnect the negative battery cable. For bleeding the hydraulic system, clean the dust cap, remove it and the diaphragm, and fill the reservoir with approved brake fluid. Route a suitable rubber tube from the bleed screw to a container to prevent brake fluid from entering the clutch housing. Loosen the bleed screw to allow fluid to move from the master cylinder to the clutch slave cylinder while keeping the reservoir full. When a steady stream of fluid comes from the clutch slave outlet, tighten the bleed screw, depress the clutch pedal, and release it rapidly, repeating this process multiple times while checking the fluid level. After ensuring the system is fully bled, check the vehicle by starting it and selecting reverse gear to confirm there is no grating of gears; if there is, repeat the bleeding procedure.
