Remove gearbox first (see sect. 2.2), after which, unscrewing the bolts, remove the clutch assembly. In this case, it must not be lifted by the thrust flange of the pressure spring. Install the clutch in the reverse order, after checking the condition of the bearing at the end of the crankshaft. If necessary, replace it using the puller shown in rice. 49. Check the condition of the splines on the hub of the driven disk and on the drive shaft of the gearbox and lubricate the splines with a thin layer of grease LSTs-15 or Litol-24. The clutch driven disc is positioned with a protruding part of the hub towards the gearbox and centered with mandrel A.70081 (pic. 63), simulating the splined end of the drive shaft of the gearbox. Therefore, instead of a mandrel, the drive shaft of the gearbox can be used.
