Using assembly tool P/N 5025030-10 pull the crankshaft
into the ignition side crankcase half. Make sure the
crankshaft is flush against the bearing.
Position the crankcase gasket onto the ignition side
crankcase half using a light coat of grease to hold it in
place.
The crankcase alignment pins should be located in
the ignition side crankcase half.
Slide the drive side crankcase half onto the crankshaft,
then mount the assembly tool. Pull the crankshaft into
the crankcase half while guiding the two halves together.
If necessary, starl a few crankcase screws to hold the
gasket in place. Make sure the crankshaft is flush
against the bearing, then remove the assembly tool.
Install all the crankcase screws except the top front
screw which also retains the bar spike and muffler sup-
port. Starting with the screws around the crankshaft,
tighten all six screws to 7-9 Nm (5.1-6.6 ft.lbs.) torque.
