CAUTION:
Do not reuse snap rings.
11. Using a piston ring expander, install the piston rings. CAUTION:
• Be careful not to damage the piston.
• When the piston rings are not replaced, remount the rings
in their original positions.
• When replacing the piston ri ngs, those without stamped
surface (A) can be mounted either side up.
• Install the second ring with the stamped surface (B) facing upward. If the ring is not stamped it can face in either
direction.
• Position each ring with the gap as shown, referring to the pis- ton front mark.

• When installing the connecting rod bearings, apply engine oil to the bearing surface (crankshaft side). Do not apply oil to the
back surface (connecting rod and cap side), but thoroughly
clean it.
• When installing, align the connecting rod bearing protrusion
with the notch of the connecting rod to install.
• Check that the oil holes on the connecting rod and on the cor- responding bearing are aligned.

CYLINDER BLOCK DISTORTION
• Using a scraper, remove any old gasket material on the cylinder block surface, and remove any oil, scale, carbon, or other contami-
nation.
CAUTION:
Be careful not to allow gasket fl akes to enter the oil or coolant
passages.
• Measure the distortion on the block upper face at different points in six directions.
• If out of specification, resurfac e the cylinder block. The allowable
amount of resurfacing is dependent on the amount of any cylinder
head resurfacing. The resurfacing limit is [amount of cylinder head resurfacing] + [amount of cylinder head
resurfacing] = 0.2 mm (0.008 in).
INNER DIAMETER OF MAIN BEARING HOUSING
• Install the main bearing caps with the main bearings removed, and tighten the bolts to the specified torque.
• Using a bore gauge, measure the inner diameter of the main bear-
ing housing (A).
• If out of the standard, replace the cylinder block and main bearing caps as an assembly.
NOTE:
These components cannot be replaced as a single unit, because
they were processed together.
PISTON-TO-CYLINDER BORE CLEARANCE
1. Using a bore gauge, measure cylinder bore for wear, out -of-round and taper at (A), (B) and (C). The X axis
is in the longitudinal direction of the engine.

ones, select piston of the sam e grade number punched on
cylinder block rear position . These numbers are punched
in either Arabic or Roman numerals.

5. Cylinder bore size is determined by adding pi
ston-to-bore clearance to piston diameter (A).
6. Install main bearing caps, and tighten to the specified torque. Otherwise, cylinder bores may be distorted after boring.
7. Cut cylinder bores. •When any cylinder needs boring, all ot her 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.
8. Hone cylinders to obtain specified piston-to-bore clearance.
9. Measure finished cylinder bore for out-of-round and taper. •Measurement should be done after cylinder bore cools down.
CRANKSHAFT
1. Check the crankshaft main and pin journals for scoring, wear, or
cracks.
2. Measure the journals for taper and out-of-round.
3. Measure crankshaft runout.
a. Place a V-block on a precise flat table to support the journals on the both ends of the crankshaft.
b. Place a dial gauge straight up on the No. 3 journal.
c. While rotating the crankshaft, read the movement of the pointer on the dial gauge.
