CYLINDER BLOCK
 If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or rebore the inner
wall.
 Oversize piston is provided. When using oversize piston, rebore
cylinder so that the clearance of the piston to cylinder bore satis-
fies the standard.
CAUTION:
When using oversize piston, use oversize pistons for all cylin-
ders with oversize piston rings.
Piston Skirt Diameter
Measure the outer diameter of piston skirt with a micrometer (A).
Piston-to-Cylinder Bore Clearance
Calculate by piston skirt diameter and cylinder bore inner diameter [direction (B), position (D)].
(Clearance) = (Cylinder bore inner diameter) – (Piston skirt diameter).
 If the calculated value exceeds the limit, replace piston and piston pin assembly. Refer to EM-129, "
Piston".
Reboring Cylinder Bore
1. Cylinder bore size is determined by adding piston to cylinder bore clearance to piston skirt diameter.
2. Install main bearing caps and main bearing beam, and tighten to the specified torque. Otherwise, cylinder
bores may be distorted in final assembly.
3. Cut cylinder bores.
NOTE:
 When any cylinder needs boring, all other cylinders must also be bored.
 Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter at a
time.
4. Hone cylinders to obtain the specified piston to cylinder bore clearance.
5. Measure finished cylinder bore for the out-of-round and taper.
NOTE:
Measurement should be done after cylinder bore cools down.
CRANKSHAFT MAIN JOURNAL DIAMETER

CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with a
micrometer (A).
 If out of the standard, measure the connecting rod bearing oil
clearance. Then use undersize bearing. Refer to EM-130,
"ConnectingRodBearing".
CRANKSHAFT OUT-OF-ROUND AND TAPER
 Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with a micrometer.
 Out-of-round is indicated by the difference in the dimensions
between (d) and (c) at (a) and (b).
 Taper is indicated by the difference in the dimensions between.
 If the measured value exceeds the limit, correct or replace crank-
shaft.
 If corrected, measure the bearing oil clearance of the corrected
main journal and/or pin journal. Then select the main bearing and/
or connecting rod bearing. Refer to EM-132, "
MainBearing" and/
or EM-130, "
ConnectingRodBearing".
CRANKSHAFT RUNOUT
 Place V-block on precise flat table, and support the journals on the both end of crankshaft.
 Place a dial indicator straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on a
dial indicator. (Total indicator reading)
 If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
 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-110, "
Disassembly and Assembly" for the
tightening procedure.
 Measure the inner diameter of connecting rod bearing with an
inside micrometer.

rod bolts to the specified torque. Refer to EM-110, "
Disassembly and Assembly" for the tightening proce-
dure.

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
caps (2), and main bearing cap bolts with main bearing beam to
the specified torque. Refer to EM-110, "
Disassembly and Assem-
bly" 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 the 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-132, "
MainBearing".
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
holes.
 Install main bearing to cylinder block and main bearing caps, and tighten main bearing cap bolts with main
bearing beam to the specified torque. Refer to EM-110, "

*: For the service parts, the grade for fitting cannot be selected between piston pin and connecting rod. (Only “0” grade is available.) The
information at the shipment from the plant is described as a reference.
 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, refer to the text.
PistonINFOID:0000000003802297
WHEN NEW CYLINDER BLOCK IS USED
Check the cylinder bore grade (“1”, “2” or “3”) on rear side of cylinder
block, and select piston of the same grade.
NOTE:
Piston is available with piston pin as a set for the service part. (Only
“0” grade piston pin is available.)
WHEN NEW CYLINDER BLOCK IS REUSED
1. Measure the cylinder bore inner diameter. Refer to EM-119, "Inspection".
2. Determine the bore grade by comparing the measurement with the values under the cylinder bore inner
diameter of the “PISTON SELECTION TABLE”.
