12. Lubricate the inner lips of the crankshaft oil
seals with grease; then slide the seals onto the
crankshaft making sure the spring side of each
seal faces the center of the crankcase.
NOTE: There is a MAG-side seal and a
PTO-side seal.
13. Apply Arctco 50: 1 Injection Oil to all of the
crankshaft bearings; then install the crankshaft
into the upper crankcase halt. Be sure the
alignment hole in each bearing is pOSitioned
over its respective dowel pin in the crankcase.
Check all bearings by trying to rotate them to make
sure they are being held in position by the dowel
pin. Each bearing must drop onto the dowel pin. If
the bearings are not properly seated during
assembly, the crankcase halves will not seal tightly
and engine damage will result.
