Disconnect the cardan shaft from the gearbox (see Replacing the cardan transmission), clutch slave cylinder (see Replacing the clutch slave cylinder).
Remove the wire tips from the terminals of the reverse light switch (see Replacing the reverse light switch).
We disconnect the clutch housing from the cylinder block and the cross member of the rear support of the power unit from the body (see Gearbox replacement).
Using a 13 mm socket, unscrew the two nuts securing the support...
...and remove it from the gearbox.
We move the gearbox back until the gear shift handle stops at the rear of the floor opening.
The gearbox will be held in place by the exhaust pipe. We additionally place a reliable support under the rear part of the gearbox.
Holding the flywheel with a mounting blade, use a 13 mm wrench to unscrew the six bolts securing the clutch housing, turning the crankshaft to access them.
We move the clutch pressure plate,...
…we remove the slave…
…and clutch pressure plates.
Pulling out from the crankcase, we remove the clutch release fork and remove the clutch release bearing from the gearbox drive shaft.
We install the clutch components in the reverse order of removal. Before installation, wipe the working surfaces of the flywheel, pressure and driven disks with a cloth soaked in gasoline. We center the leading and driven disks relative to the bearing at the end of the crankshaft, using a mandrel simulating the end of the primary shaft of the gearbox (see Fig. Applications). After tightening the bolts securing the clutch housing to the flywheel, the mandrel should be freely removed from the bearing by hand.
Before installing the gearbox, lubricate the splines of the primary shaft with a thin layer of SHRUS-4 grease.
Having installed the clutch, we adjust the free travel of the clutch slave cylinder pusher (see Drive adjustment).
