CYLINDER BLOCK


Using a piston ring compressor (special service tool) or suit-
able tool, install piston with the front mark on the piston head
facing the front of the engine.
CAUTION:
Be careful not to damage the cylinder wall and crankshaft
pin, resulting from an interference of the connecting rod
big end.
11. Install connecting rod cap.

Match the stamped cylinder number marks on connecting rod
with those on connecting rod cap to install.
12. Tighten connecting rod bolt with the following procedure:
a. Apply new engine oil to the threads and seats of connecting rod bolts.
b. Tighten bolts.
c. Then turn all bolts 90 degrees clockwise (Angle tightening).
CAUTION:
Check and confirm the tightening angle by using an angle
wrench (special service tool) or protractor. Avoid judge-
ment by visual inspection without the tool.

After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-107, "CONNECTING ROD SIDE CLEARANCE" .
13. Install flywheel (M/T models) or drive plate (A/T models).
CAUTION:
Make sure that dowel pin is installed at the rear end of crankshaft.

When installing flywheel (M/T models) or drive plate (A/T models) to crankshaft, make sure that align
crankshaft side dowel pin with flywheel/drive-plate side dowel pin hole correctly.
CAUTION:
If these are not aligned correctly, engine runs roughly and “MI” turns on.

Secure crankshaft with a stopper plate, and tighten mounting bolts crosswise over several times.

CONNECTING ROD BEND AND TORSION

Check with a connecting rod aligner.

If it exceeds the limit, replace connecting rod assembly.
CONNECTING ROD BIG END DIAMETER

Install connecting rod cap without connecting rod bearing installed, and tightening connecting rod bolts to
the specified torque. Refer to EM-94, "
ASSEMBLY" for the tightening procedure.

Measure the inner diameter of connecting rod big end with an
inside micrometer.

If out of the standard, replace connecting rod assembly.

PRECAUTIONS

[YD22DDTi]PRECAUTIONSPFP:00001
Precautions for Draining Engine CoolantEBS00LQZ
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS00LR0

Before starting work, make sure no fire or spark producing items are in the work area.

After disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS00LR1

When instructed to use special service tools, use the specified 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 equivalent, if necessary, to seal out foreign materials.

Mark and arrange disassembly parts in an organized way for easy troubleshooting and re-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 specified, do exactly as specified.
Precautions for Inspection, Repair and ReplacementEBS00LR2
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS00LR3

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 speci-
fied, do exactly as specified.

Replace with new liquid gasket, packing, oil seal or O-ring.

Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,
make sure that dowel pins are installed in the original position.

Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine 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, engine oil sliding surfaces well.

Release air within route when refilling after draining coolant.

After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angle TighteningEBS00LR4

Use an angle wrench (special service tool: KV10112100) for the final tightening of the following engine
parts:
–Cylinder head bolts
–Main bearing cap bolts
–Connecting rod cap nuts
–Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angle
tightening)

Do not use a torque value for final tightening.

The torque value for these parts are for a preliminary step.

Ensure thread and seat surfaces are clean and coated with engine oil.

DRIVE BELTS

DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00LRA

Before inspecting engine, make sure engine has cooled down;
wait approximately 30 minutes after engine has been stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00LRB

Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant.

Do not twist or bend the belts with strong force.
