DISASSEMBLING THE CRANKCASE
1. Remove:
crankcase bolts
A Upper crankcase
B Lower crankcase
Loosen each bolt 1 / 4 of a turn at a time, in
stages and in a crisscross pattern. After all of
the bolts are fully loosened, remove them.
Loosen the bolts in decreasing numerical or-
der (refer to the numbers in the illustration).
The numbers embossed on the crankcase in-
dicate the crankcase tightening sequence.
2. Remove:

Tap on one side of the crankcase with a soft-
face hammer. Tap only on reinforced por-
tions of the crankcase, not on the crankcase
mating surfaces. Work slowly and carefully
and make sure that the crankcase halves
separate evenly.
3. Remove:
dowel pins
O-ring
4. Remove:
crankshaft journal lower bearing
(from the lower crankcase)
Identify the position of each crankshaft journal
lower bearing so that it can be reinstalled in its
original place.
