half revolutions.
NOTE:
If this has already been done, you are not required to do

and plate (C) using a caliper. The distance must be
17.75 mm (0.70 in.) and must be consistent all around.
4. Tighten nuts using the sequence shown at right. Once
the discs are nearing the 17.75 mm (0.70 in.)
dimension, check discs for looseness. Do NOT tighten
the discs excessively. Try to achieve a balance between
the clutch slipping during excessive loading and/or
shock loading and not slipping during normal
operation.
5. Test the clutch operation, and adjust evenly as required.
