2) Assemble the main bearings on the cylinder block and
apply engine oil to the bearings. When doing so,
assemble the bearings with holes on the cylinder block
and the bearings without holes on the bearing caps,
taking care not to mix them up.

3) Temporarily assemble one bolt in each bolt hole on either
side of the crankshaft; then, after attaching wires, lift the
crankshaft with a crane or chain block and lower it care-
fully onto the cylinder block.
4) Apply engine oil to the crankshaft journal and pin, and fit
the main bearings in the bearing caps; then, check the
numbers to avoid mixing up the bearing caps and install
them on the cylinder block.

5) Assemble the bearing cap bolts in the correct tightening
sequence at the specified tightening torque (30 kgf·m /
216.99 lbf·ft) using the rotating angle method (90°+10°).
The tightening sequence is as follows.
< Bearing cap tightening sequence >
- Step 1: Tighten the bolts one or two threads by hand
- Step 2: Use a wrench to tighten them to approx.
15 kgf·m (108.495 lbf·ft)
- Step 3: Tighten them with a torque wrench (approx.
25 kgf·m / 180.8 lbf·ft)
- Step 4: Tighten them with a torque wrench (approx.
30 kgf·m / 217 lbf·ft)
- Step 5: Tighten them one last time with the rotating
angle method (90° + 10°)
Make sure to tighten the bolts in several steps according
to the tightening sequence above.
6) Check whether the crankshaft rotates smoothly.
7) Assemble the crankshaft gear with the crankshaft and
mark gear tooth "1" with white paint to identify it easily.
