face. Do not use any tool smaller than taper pin
bore to remove the pin.
Remove the four crankcase flange screws and six
main bearing screws.
Turn the powerhead so the intake manifold sur-
face faces up.
Using a rawhide mallet, lightly tap upward on the
crankshaft until the halves just begin to separate.
Lift up and remove the crankcase.
IMPORTANT: Pistons, connecting rods, needle
bearings, and liners are wearing parts and seat
with the operation of the engine. Because of this,
it is essential to maintain their original positions at
reassembly.
Use an indelible ink marker to mark each compo-
nent when it is removed to ensure correct mating.
Keep the needles of each cylinder together.
IMPORTANT: Loosely install the cylinder head
to prevent the pistons from falling out when the
crankshaft is removed.
