Thoroughly clean all parts to be assembled.
Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
Install the crankshaft main bearings.
Upper bearings have an oil groove of oil holes; Lower bearings do not.
Align the bearing claw with the claw groove of the cylinder block, and push in the 4 upper bearings (A).
Install the 2 thrust bearings (A) under the No. 2 journal position of the cylinder block with the oil grooves facing outward.
Place the crankshaft (A) on the cylinder block.
Install the main bearing cap (A).
Always use new crankshaft main bearing cap bolts. Crankshaft main bearing cap bolts are torque-to-yield bolts designed to be permanently elongated beyond the state of elasticity when torqued, so if the bolts are removed and reused, it may cause the bolts to break or fail to maintain clamping force.
Replace any broken or deformed bearing cap bolts.
Install and tighten the 8 main bearing cap bolts, in several passes, in the sequence shown.
Tightening torque :
17.7 ~ 21.6 N.m (1.8 ~ 2.2 kgf.m, 13.0 ~ 15.9 lb-ft) + 103 ~ 105°
Using the SST (09221-4A000), tighten the bolts that need to be tightened in the angular tightening method.
Check that the crankshaft turns smoothly.
Check the crankshaft end play.
Assemble the remaining parts in the reverse order of disassembly.
In case the crankshaft is replaced with a new one, select the proper connecting rod bearing according to the pin journal mark on the crankshaft.
