Thoroughly clean all parts to be assembled.
Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
Replace all gaskets, O-rings and oil seals with new parts.
Install the 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, push in the 4 upper bearings(A).
Align the bearing claw with the claw groove of the main bearing cap, and push in the 4 lower bearings.
Install the thrust bearings.
Install the 2 thrust bearings(A) under the No.3 journal position of the cylinder block with the oil grooves facing outward.
Place the crankshaft(A) on the cylinder block.
Place the main bearing caps on cylinder block.
Install the main bearing cap bolts.
Install and uniformly tighten the bearing cap bolts, in several passes, in the sequence shown.
Tightening torque
Main bearing cap bolt
No.1~8 : 49.0 N.m (5.0 kgf.m, 36.2 lb-ft) + 90°
No.9~16 : 19.6 N.m (2.0 kgf.m, 14.5 lb-ft) + 120°
No.17~24 :
29.4 ~ 31.4 N.m (3.0 ~ 3.2 kgf.m, 21.7 ~ 23.1 lb-ft)
Always use new main bearing cap bolts.
If any of the bearing cap bolts are broken or deformed, replace it.
Use the SST( 09221-4A000 ), install main bearing cap bolts.
Check that the crankshaft turns smoothly.
Check crankshaft end play.
Install the piston and connecting rod assemblies.
(Refer to Cylinder Block - "Piston and Connecting rod")
Install the rear oil seal case(A).
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Clean the sealing face before assembling two parts.
Remove harmful foreign materials on the sealing face before applying sealant
Before assembling rear oil seal case, the liquid sealant THREE BOND 1217H should be applied to the rear oil seal case.
The part must be assembled within 5 minutes after sealant was applied.
Apply sealant to the inner threads of the bolt holes.
Install the rear oil seal.
(Refer to Cylinder Bolck - "Rear Oil Seal")
Install the baffle plate.
Install and uniformly tighten the baffle plate bolts, in several passes, in the sequence shown.
Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
Install all other parts in reverse order of removal.
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.
Connecting rod bearing selection
(Refer to Cylinder Block - "Piston and Connecting Rod")
