6) Install crankcase (1) to cylinder block. Apply oil to crankcase
bolts before installing them. Tighten crankcase bolts gradu-
ally as follows.
a) Tighten all bolts to 42 N·m (4.2 kg-m, 30.5 lb-ft) according
to numerical order in figure.
b) Loosen all bolts until tightening torque is reduced to 0 in
reverse order of tightening.
c) In the same manner as in Step a), tighten them to 42 N·m
(4.2 kg-m, 30.5 lb-ft).
d) In the same manner as in Step a) again, tighten them to
specified torque.
NOTE:
Tighten 10 mm (0.394 in.) thread diameter bolts first (fol-
lowing the order shown in figure), then tighten 8 mm
(0.315 in.) thread diameter bolts.
