Disconnect the muffler pipe hanger at the rear of the vehicle and then the muffler pipe from the exhaust pipe. Disconnect the clamp securing the intake pipe to the gearbox. Using the wrench 02.7812.9500, unscrew the nuts securing the intake pipe of the mufflers to the exhaust manifold and remove the pipe. Remove the lower bolts securing the clutch housing cover and disconnect the ground wire from the clutch housing and wires from the reversing light switch.
Unhook the release spring 24 (see fig. 110) from the clutch release fork 11 and remove the cotter pin from the pusher 19. Disconnect the slave cylinder 23 from the clutch housing. In this case, the cylinder 23, connected to the pipeline going to the master cylinder of the clutch release actuator, remains on the vehicle, which eliminates the loss of brake fluid and the need to pump the hydraulic clutch actuator.
Remove safety bracket 24 (see fig. 126) propeller shaft, then disconnect the speedometer flexible shaft from the speedometer drive gearbox.
Put on the elastic sleeve 3 (pic. 116) collar A.70025 (5) and tighten it. This facilitates the removal and installation of the flexible coupling. Unscrew nuts 2 and, turning the cardan shaft, remove the bolts securing the flexible coupling to the flange of the output shaft of the gearbox. Lower and move aside the front driveshaft with clutch.
Unscrew the 02.7812.9500 articulated wrench bolts securing the starter to the clutch housing and remove it. Detach the rear engine mount from cross member 1 and remove the cross member while supporting the gearboxes from below. Place a stand under the gearbox housing and unscrew the bolts securing the clutch housing with the A.55035 hinge key, then remove the gearbox together with the clutch housing, shifting it back to remove the input shaft from the front bearing and the driven disk hub.
When withdrawing (installation) gearbox, the end of the input shaft must not be supported on the thrust flange of the clutch pressure spring, so as not to deform the clutch connecting plates.
