- insert the crankcase fastening screws and tighten
it them to the specified torque.

- Complete the coupling operations with the verifi-
cation of the crankshaft axial clearance.
- Using specific tools to support the dial gauge,
verify that the fitting clearance is within the limits.
- Higher clearances are signs of wear of the crank-
shaft - crankcase supporting surfaces.
