Thoroughly clean all parts to assembled.
Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
Install the crankshaft main bearings.
Upper 1, 2, 4, 5 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 5 upper bearings (A).
Align the bearing claw with the claw groove of the main bearing cap, and push in the 5 lower bearings.
Place the crankshaft on the cylinder block (A).
Place the bed plate on the cylinder block (A).
Standard liquid gasket : FD20, HYLOMAR3000, Dreibond 5105
Check that the mating surfaces are clean and dry before applying liquid gasket.
Apply liquid gasket in a 3mm wide bead without discontinuity.
Remove the extruded sealant after installing bed plate.
Install the bed plate bolts.
The bed plate bolts are tightened in 2 progressive steps.
If any of the bed plate bolts in broken or deformed, replace it.
Apply a light coat of engine oil on the threads and under the bed plate bolts.
Tighten the bolts (11, 17, 20) in numerical order.
Tighten the main bearing cap bolts (1~10) in numerical order using the SST (09221-4A000).
Loosen the bolts (11, 17, 20).
Tighten the bolts (11~20) in numerical order.
Tighten torque of main bearing cap bolts.
Tightening torque
Long bolts (1~10) :
22.6 ~ 26.5 N.m (2.3 ~ 2.7 kgf.m, 16.6 ~ 19.5 lb-ft) + 90 ~ 94°
Short bolts (11~20) :
32.4 ~ 36.3 N.m (3.3 ~ 3.7 kgf.m, 23.9 ~ 26.8 lb-ft)
Always use new crankshaft main bearing cap bolts. Crankshaft main bearing cap bolts are toque-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.
Check that the crankshaft turns smoothly.
Check the crankshaft end play.
Assemble the other 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.
Connecting rod bearing selection
