CYLINDER BLOCK
Never rotate crankshaft.
 Remove connecting rod cap and bearing, and using the scale on
the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
 Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-101, "
Disassembly and Assembly".
 Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
 If the clearance exceeds the limit, select proper main bearing
according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-119, "
MainBearing".
Method of Using Plastigage
 Remove engine oil and dust on crankshaft main 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 main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec-
ified torque. Refer to EM-101, "
Disassembly and Assembly".
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
same as that described in the “Method by Calculation”.

bearing No. 1 of the cylinder block.
l. Install the main bearing caps on bearing cap No. 1 (these are

opposite the water pump). Then tighten the bolts to a torque of
25 N·m (2.6 kg-m, 18 ft-lb) plus an angle tightening of 47
degrees.
m. Turn all bolts 47 degrees clockwise (angle tightening).
CAUTION:
Check and confirm the tightening angle by using the angle
wrench [SST: KV10112100 ( — )] or protractor. Avoid judg-
ment by visual inspection without the tool.
n. Check the lateral play. Refer to EM-330, "
