1. Remove the gearbox.
2. If you plan to reinstall the removed clutch, mark the pressure plate and flywheel with scratches to mount them again in the old position.
3. In order for the membrane spring not to get one-sided curvature, unscrew the 6 bolts of the clutch pressure plate from the flywheel evenly crosswise in turn, unscrewing 1-1.5 turns until the pressure plate is loosened.
4. In order to prevent the flywheel from rotating, fix it if necessary with a screwdriver inserted into the teeth and resting on some bolt in the engine housing. In the workshop, a special locking device is used for this (Mot. 582), which is screwed into the engine housing and engages with the teeth of the flywheel.
5. Take out pressure and conducted disks.
6. Blow the flywheel with compressed air or wipe it with a rag soaked in gasoline.
7. Install the old pressure plate only if its rivet connections are strong enough.
8. The supporting surface of the driven disk must not have cracks or burnt areas.
9. Lubricate the nickel-plated internal engagement of the driven disc with a small amount of «Molykote 55 plus».
10. Measure the thickness of the driven disk coating - must be at least 7.7 mm (for all engines).
11. Put the driven and pressure plate on the flywheel, with the flat side facing the flywheel.
12. Center the driven disk with a special mandrel. For better centering on motor type «F» an auxiliary sleeve is supplied, which, together with a small amount of «Curil» is inserted in the direction of installation until it stops in the hole in the crankshaft.
13. Tighten the pressure plate mounting bolts crosswise (bolts 7 mm = 18 Nm.; bolts 8 mm = 25 Nm.).
