ENGINE UNIT
Install connecting rod bearings (2) to connecting rod (3) and con-
necting rod bearing cap (1), and tighten connecting rod bolts to the
specified torque. Refer to EM-212, "
Disassembly and Assembly"
for tightening procedure.
Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)
If clearance exceeds the limit, select proper connecting rod bearing according to connecting rod big end
diameter and crankshaft pin journal diameter to obtain specified bearing oil clearance. Refer to EM-230,
"How to Select Piston and Bearing".
Method of Using Plastigage
Remove engine oil and dust on crankshaft pin 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 cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-212, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Never rotate crankshaft.
Remove connecting rod cap and bearing, and using the scale (A)
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 (3) to cylinder block (1) and main bearing cap
(2), and tighten main bearing cap bolts to the specified torque.
Refer to EM-212, "
Disassembly and Assembly" for the tightening
procedure.
Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)

DESCRIPTION
The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the
measurement with the values of each selection table.
For details of the measurement method of each part, the reuse standards and the selection method of the
selective fitting parts, follow the procedures.
HOW TO SELECT PISTON
When New Cylinder Block is Used
Check the cylinder bore grade on rear left side of cylinder block (L),
and select piston of the same grade.
If there is a correction stamp mark on the cylinder block, use it as a
correct reference.
When Cylinder Block is Reused
1. Measure the cylinder bore inner diameter. Refer to EM-219, "Inspection After Disassembly".
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.
