Crank Case bolts
Apply engine oil to bolt threads and seats of crank case bolt No.1 and tighten bolt to 50 Nm (5.1 kgf-m, 37.0 lbf-ft) in numerical order ("1". "10") evenly and gradually.
Loosen all bolts in reverse numerical order until loosening torque becomes 0.
In the same manner as Step a), retighten them to 20 Nm (2.0 kgf-m, 15.0 lbf-ft).
In the same manner as Step a), retighten them to 35 Nm (3.6 kgf-m, 26.0 lbf-ft).
In the same manner as Step a), retighten them to 40 degrees.
In the same manner as Step a), retighten them to 40 degrees.
Tighten crank case bolt No.2s in numerical order ("1" - "12") evenly and gradually.
Crank case bolt No.2* (a): 25 Nm (2.5 kg-m, 18.5 lbf-ft)
