NOTE:
When determining cylinder bore grade, measure the cylinder bore
at (B) position.
• If measured value exceeds limit or if there are scratches and/or seizure on the cylinder inner wall hone or re-
bore the cylinder inner wall.
Piston Skirt Diameter
• Measure outer diameter of piston skirt with suitable tool (A).
Piston to Cylinder Bore Clearance
• (Piston to cylinder bore clearance) = (Cylinder bore inner diameter) - (Piston skirt diameter)
• If measured value exceeds limit replace piston and piston pin assembly..
PISTON RING END GAP
• Check that cylinder bore inner diameter is within standards.
• Lubricate with new engine oil to piston (1) and piston ring (2), and
then insert (A) piston ring to middle of cylinder (B) with piston and
measure piston ring end gap using suitable tool (C).
• If measured value exceeds limit replace piston ring and measure
again. If it still exceeds the limit replace cylinder block.

CYLINDER BLOCK
• Measure outer diameter of crankshaft main journals using suitable
tool (A).
• If measured value exceeds limit measure the main bearing oil
clearance and use undersize bearing.
CRANKSHAFT PIN JOURNAL DIAMETER
• Measure outer diameter of crankshaft pin journal using suitable tool.
• If measured value exceeds limit measure connecting rod bearing oil clearance and use undersize bearing.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
• Measure dimensions at four different points as shown on each
main journal and pin journal using suitable tool.
• Out-of-round is indicated by the difference in dimension between
(a) and (b) at (c) and (d).
• Taper is indicated by difference in dimension between (c) and (d)
at (a) and (b).
• If measured value exceeds limit correct or replace crankshaft.
• If corrected, measure bearing oil clearance of corrected main journal and/or pin journal. Then select main
bearing and/or connecting rod bearing.
CRANKSHAFT RUNOUT
• Place V-block on precise flat table to support the journals on both
ends of crankshaft.
• Place suitable tool (A) straight up on No. 3 journal.
• While rotating crankshaft, read movement of pointer on suitable
tool. (Total indicator reading)
• If measured value exceeds limit replace crankshaft.

• Install connecting rod bearings (2) to connecting rod (3) and con-
necting rod bearings cap (1) and tighten connecting rod bolts.
EM-98, "Disassembly and Assembly"
.
• Measure inner diameter (B) of connecting rod bearing using suit-
able tool.
• (Bearing oil clearance) = (Connecting rod bearing inner diameter) -
(Crankshaft pin journal diameter)
• If measured value exceeds limit select proper connecting rod bearing. Use connecting rod big end diameter
and crankshaft pin journal diameter to obtain specified bearing oil clearance.
Method by Using Plastigage
• Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely.
• Cut plastigage slightly shorter than 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. Refer to
.
CAUTION:
Do not 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 lower cylinder
block (2) and tighten lower cylinder block bolts. Refer to
.
• Measure the inner diameter (B) of main bearing with bore gauge.
• (Bearing oil clearance) = (Main bearing inner diameter) - (Crank-
shaft main journal diameter)
• If measured value exceeds limit select proper main bearing. Use
main bearing inner diameter and crankshaft main journal diameter to obtain specified bearing oil clearance.

.
Method by Using Plastigage
• Remove engine oil and dust on crankshaft main journal and surfaces of each bearing completely.
• Cut plastigage slightly shorter than bearing width and place it in crankshaft axial direction avoiding oil holes.
• Install main bearings on cylinder block and lower cylinder block and tighten lower cylinder block bolts. Refer
EM-98, "Disassembly and Assembly"
.
CAUTION:
Do not rotate crankshaft.

CYLINDER BLOCK
• Remove lower cylinder block and bearings and using the scale (A)
on the plastigage bag measure the plastigage width.
NOTE:
The procedure when measured value exceeds the limit is same as
that described in “Method by Calculation”.
MAIN BEARING CRUSH HEIGHT
• When lower cylinder block is removed after being tightened to
specified torque with main bearings (1) installed, tip end of bearing
must protrude (B). Refer to
EM-98, "Disassembly and Assembly"
.
• If standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
• When connecting rod bearing cap is removed after being tightened
to specified torque with connecting rod bearings (1) installed, tip
end of bearing must protrude (B). Refer to
.
• If standard is not met, replace connecting rod bearings.
LOWER CYLINDER BLOCK BOLT OUTER DIAMETER
• Measure outer diameters (d1) and (d2) at two positions as shown.
• If reduction appears in (B) range, regard it as (d
2
).
• If measured value exceeds limit (a large difference in dimensions)
replace lower cylinder block bolt with new one.
