6) Install lower crankcase (1) to cylinder block. After applying engine oil to all crankcase bolts ((1) - (22)), tighten them gradually as follows.
a) Tighten bolts ((1) - (10)) to 40 Nm (4.0 kgf-cm, 29.0 ft. lbs.).
b) Loosen bolts ((1) - (10)) until tightening torque is reduced to 0 (zero) in reverse order of tightening.
c) In the same manner as in step a), tighten them to 40 Nm (4.0 kgf-cm, 29.0 ft. lbs.).
d) In the same manner as in step a), tighten them to the specified torque.
e) Tighten bolts ((11) - (22)) to the specified torque according to numerical order.
Tightening torque
Crankcase bolt with 10 mm thread diameter ((1) - (10)) 59 Nm (5.9 kgf-cm, 42.5 ft. lbs.)
Crankcase bolt with 8 mm thread diameter ((11) - (22)) 27 Nm (2.7 kgf-cm, 19.5 ft. lbs.)
NOTE: After tightening crankcase bolts, check to be sure that crankshaft rotates smoothly when turned by hand.
7) Pull out dowel pin (2) from crankshaft (1) and then install rear oil seal (3) by using special tools and plastic hammer.
