Measure the distortion on the cylinder block upper face at some
different points in six directions with straight edge and feeler
gauge.
If it exceeds the limit, replace cylinder block and lower cylinder
block assembly.
NOTE:
Cylinder block cannot be replaced as a single, because it is
machined together with lower cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
Install lower cylinder block without main bearings installed, and
tighten lower cylinder mounting bolts to the specified torque.
Refer to EM-86, "
ASSEMBLY" for the tightening procedure.
Measure the inner diameter of main bearing housing with bore
gauge.
If out of the standard, replace cylinder block and lower cylinder
block assembly.
NOTE:
Cylinder block cannot be replaced as a single, because it is
machined together with lower cylinder block.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter
Using bore gauge, measure the cylinder bore for wear, out-of-
round and taper at six different points on each cylinder. (“X” and
“Y” directions at “A”, “B” and “C”) (“Y” is in longitudinal direction
of engine)
NOTE:
When determining cylinder bore grade, measure the cylinder
bore at “B” position.
If the measured value exceeds the limit, or if there are scratches and/or seizure on the cylinder inner wall,
hone or re-bore the cylinder inner wall.
Oversize piston is provided. When using oversize piston, re-bore the cylinder so that the clearance of the
piston to cylinder bore satisfies the standard.
CAUTION:
When using an oversize piston, use oversize pistons for all cylinders with oversize piston rings.Limit: 0.1 mm (0.004 in)

CRANKSHAFT PIN JOURNAL DIAMETER
Measure the outer diameter of crankshaft pin journal with micrometer.
If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
Refer to EM-105, "
CONNECTING ROD BEARING OIL CLEARANCE" .
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with micrometer.
Out-of-round is indicated by the difference in dimensions
between “X” and “Y” at “A” and “B”.
Taper is indicated by the difference in dimension between “A”
and “B” at “X” and “Y”.
If the measured valve exceeds the limit, correct or replace crankshaft.
If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then
select main bearing and/or connecting rod bearing. Refer to EM-106, "
MAIN BEARING OIL CLEAR-
ANCE" and/or EM-105, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT
Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.
Place a dial indicator straight up on the No. 3 journal.
While rotating crankshaft, read the movement of the pointer on
the dial indicator. (Total indicator reading)
If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the speci-
fied torque. Refer to EM-86, "
ASSEMBLY" for the tightening procedure.
Measure the inner diameter of connecting rod bearing with
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diame-
ter) – (Crankshaft pin journal diameter)
If the 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-92, "
HOW TO SELECT CONNECTING
ROD BEARING" .
Method of Using Plastigage
Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely. Standard: 44.956 - 44.974 mm (1.7699-1.7706 in) dia.
Limit:
Out-of-round (Difference between “X” and “Y”)
: 0.005 mm (0.0002 in)
Taper (Difference between “A” and “B”)
: 0.005 mm (0.0002 in)

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 lower cylinder block, and tighten lower cylinder block mounting
bolts to the specified torque. Refer to EM-86, "
ASSEMBLY" for the tightening procedure.

shaft main journal diameter)
If the clearance exceeds the limit, select proper main bearing
