9. Using a suitable tool, install piston rings. CAUTION:
• Be careful not to damage piston.
• Be careful not to damage piston rings by expanding them excessively.
• Position each ring with the gap as shown referring to the pis-
ton front mark (B).
• Install second ring with the stamped mark (E) facing upward.
10. Install connecting rod bearings to connecting rod and connecting rod cap. • When installing connecting rod bearings, apply new engine oil to the bearing surface (inside). Do not
apply engine oil to the back surface, but thoroughly clean it.

There is no stopper tab.
• Make sure that the oil holes on connecting rod and connecting rod bearing are aligned.
• Install the connecting rod in the dimension shown.
NOTE:
Install the connecting rod bearing in the center pos ition with the dimension shown. For service opera-
tion, the center position can be checked visually.
11. Install piston and connecting rod assembly to crankshaft. • Position crankshaft pin corres ponding to connecting rod to be installed onto the bottom dead center.
• Apply new engine oil sufficiently to the cylinder bore, piston and crankshaft pin.
• Match the cylinder position with the cy linder number on connecting rod to install.

Measure the inner diameter of piston pin hole with an inside
micrometer.
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with a micrometer.
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pi
n hole diameter) – (Piston pin outer diameter)
• If oil clearance is out of the standard, replace piston and piston pin assembly.
PISTON RING SIDE CLEARANCE
• Measure the side clearance of piston ring and piston ring groove with a feeler gauge.
• If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit, replace piston also.
PISTON RING END GAP
• Make sure that cylinder bore inner diameter is within the specifica-
tion. Check "Cylinder Bore Inner Diameter".
• Lubricate with new engine oil to piston and piston ring, and then insert piston ring until middle of cylinder with piston, and measure
piston ring end gap with a feeler gauge.
• If the measured value exceeds the limit, replace piston ring.

5. When the repair work is completed, return the ignition switch to the
″LOCK ″ position before connecting
the battery cables. (At this time, the steering lock mechanism will engage.)
6. Perform a self-diagnosis check of al l control units using CONSULT-III.
Precaution for Procedure without Cowl Top CoverINFOID:0000000005930985
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Precaution for Drain CoolantINFOID:0000000005930986
• Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000005930987
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and DisassemblyINFOID:0000000005930988
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally
opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000005930989
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000005930990
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage.

Checking Drive BeltsINFOID:0000000005930998
WARNING:
Be sure to perform this step
when the engine is stopped.
NOTE:
On vehicles not equipped with A/C, there is an idler pulley in the position for the drive belt routing.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use
range.
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range.
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of t he possible use range or belt is damaged, replace drive belt.
Tension AdjustmentINFOID:0000000005930999
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
Removal and InstallationINFOID:0000000005931000
REMOVAL
1. Remove fender protector (RH). Refer to EI-26, "Removal and Installation".
2. Hold the hexagonal part (A) of drive belt auto-tensioner (1) with a wrench securely. Then move the wrench handle in the direc-
tion of arrow (loosening direction of tensioner).
WARNING:
Never place hand in a location where pinching may occur if
the holding tool acci dentally comes off.
CAUTION:
Do not loosen the auto-tensione r pulley bolt. (Do not turn it
counterclockwise.) If turned counterclockwise, the com-
plete auto-tensioner must be replaced as a unit, including
pulley.
3. Insert a rod such as short-length screwdriver approximately 6 mm (0.24 in) in diameter into the hole (B) of t he retaining boss to fix drive belt auto-tensioner.
• Leave tensioner pulley arm locked until belt is installed again.
4. Remove drive belt.
