CYLINDER BLOCK DISTORTION
• Using a scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.
• Measure the distortion on the cylinder block upper face at some
different points in six directions (C), (D), (E), (F), (G), and (H) with a
straightedge (A) and a feeler gauge (B).
• If it exceeds the limit, replace cylinder block.

PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore inner Diameter
• Using a bore gauge, measure cylinder bore for wear, out-of-round
and taper at six different points on each cylinder. [(A) and (B) direc-
tions at (C), (D) and (E)] is in longitudinal direction of engine.
• 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 diame-
ter).
• If the calculated value exceeds the limit, replace piston and piston pin assembly. Refer to
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
• Measure the outer diameter of crankshaft main journals with a micrometer.
• If out of the standard, measure the main bearing oil clearance. Then use undersize bearing. Refer to
.
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
.
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
and/
EM-137, "Connecting Rod Bearing"
.
CRANKSHAFT RUNOUT
• Place V-block on precise flat table, and support the journals on the both end of crankshaft.
Rebored size calculation: D = A + B – C

specified bearing oil clearance. Refer to
EM-137, "Connecting Rod Bearing"
Method of Using Plastigage
• Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.

*: 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.
