b. Install thrust bearings (2) to both sides of the No. 3 journal hous-
ing on cylinder block (1).
Install thrust bearings with the oil groove (A) facing crankshaftarm (outside).
c. Install main bearings paying attention to the direction. Main bearing with oil hole (B) and groove (C) goes on cylinderblock. The one without them goes on main bearing cap.
Before installing main bearings, apply engine oil to the bearing surface (inside). Do not apply engine oil to the back surface,
but thoroughly clean it.
When installing, align main bearing stopper protrusion to cut-
out of cylinder block and main bearing.
Ensure the oil holes on cylinder block and those on the corre-
sponding bearing are aligned.
5. Install crankshaft to cylinder block. While turning crankshaft by hand, check that it turns smoothly.
6. Install main bearing caps as per the following: Align the identification number to the journal position to install.
Install it with the front mark (indicated by stamping) facing thefront of engine.
Using plastic hammer or similar tool, tap them lightly to seat them on the installation position.
NOTE:
Main bearing cap cannot be replaced as a single parts,
because it is machined together with cylinder block.
7. Install each main bearing cap bolts as per the following: CAUTION:
If main bearing cap bolts and sub bolts are re-u sed, check their outer diameters before installa-
tion. Refer to EM-115, "
Inspection".
a. Apply new engine oil to threads and seat surfaces of main bearing cap bolts and sub bolts.
b. Tighten all bolts in order of (No. 1 - 30) temporarily.
c. Tighten main bearing cap bolts (M12) in order of No. 1 - 10.
d. Tighten main bearing cap sub bolts (M9) in order of No. 11 - 20.

CYLINDER BLOCK
Install connecting rod bearings (1) to connecting rod (2) and con-necting rod cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-107, "
Disassembly and Assembly" for the
tightening procedure.
Measure the inner diameter of connecting rod bearing with an inside micrometer.
(Oil clearance) = (Connecting rod bearing inner di ameter) – (Crankshaft pin journal diameter)
If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-125, "
Description".
Method of Using Plastigage
Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
Install connecting rod bearings to connecting rod and connecting rod bearing cap, and tighten connecting
rod bolts to the specified torque. Refer to EM-107, "
Disassembly and Assembly" for the tightening proce-
dure.
CAUTION:
Never rotate crankshaft.
Remove connecting rod bearing cap and bearings, and using the
scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured va lue exceeds the limit is the
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
Install main bearings (3) to cylinder block (1) and main bearing cap (2), and tighten main bearing cap bolts to the specified torque.
Refer to EM-107, "
Disassembly and Assembly" for the tightening
procedure.
Measure the inner diameter of main bearing with a bore gauge.
(Oil clearance) = (Main bearing inner diameter) – (Crankshaft main
journal diameter)
If the calculated value exceeds t he limit, select proper main bear-
ing according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-125, "
Description".
Method of Using Plastigage
Remove engine oil and dust on crankshaft journal and the surfaces of each bearing completely.

Cut a plastigage slightly shorter than the bearing width,
and place it in crankshaft axial direction, avoiding oil

Install main bearing to cylinder block and main bearing cap, and tighten main bearing cap bolts with main
bearing cap to the specified torque. Refer to EM-107, "
Disassembly and Assembly" for the tightening proce-
dure.
CAUTION:
Never rotate crankshaft.
Remove main bearing cap and bearings, and using the scale on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is the
same as that described in the “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT
When main bearing cap is removed after being tightened to thespecified torque with main bearings (1) installed, the tip end of
bearing must protrude. Refer to EM-107, "
Disassembly and
Assembly" for the tightening procedure.
If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings (1) installed,
the tip end of bearing must protrude. Refer to EM-107, "
Disassem-
bly and Assembly" for the tightening procedure.
If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
Measure the outer diameters (A), (B) at two positions as shown in
the figure.
If reduction appears in (A) range, regard it (B).
If it exceeds the limit (large difference in dimensions), replace main bearing cap bolts with new one.
