Install the crankshaft rear oil seal holder with a new gasket.
Install the flywheel on the crankshaft. Block the flywheel with a retainer and tighten the new mounting bolts, having previously applied a sealant such as Loctite 270 to them.
Remove the retainer. Install the indicator stand so that the indicator leg rests on the ground surface of the flywheel. Moving the shaft in the longitudinal direction with a lever, measure the axial clearance of the shaft with an indicator, which should be within 0.085-0.174 mm.
