After tightening the crankcase bolts, wipe up the liquid
gasket seeping out around the mating surface, espe-
cially around the area.
Make sure that the crankshaft, driveshaft, and the output
shaft, rotate smoothy (in the neutral position).
If the crankshaft will not turn, probably the crankshaft is
