PRECAUTIONS
PRECAUTIONS
PFP:00001
Precautions for Draining Engine CoolantEBS01E5H
Drain engine coolant when engine is cooled.
Precautions for Disconnecting Fuel PipingEBS01E5I
lBefore starting work, make sure no fire or spark producing items are in the work area.
lAfter disconnecting pipes, plug openings to stop fuel leakage.
Precautions for Removal and DisassemblyEBS01E5J
lWhen instructed to use SST, use the specified tools. Always be careful to work safely, avoid forceful or
uninstructed operations.
lExercise maximum care to avoid damage to mating or sliding surfaces.
lCover openings of engine system with tape or the equivalent, if necessary, to seal out foreign materials.
lMark and arrange disassembly parts in an organized way for easy troubleshooting and re-assembly.
lWhen 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 ReplacementEBS01E5K
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precautions for Assembly and InstallationEBS01E5L
lUsetorquewrenchtotightenboltsornutstospecification.
lWhen 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.
lReplace with new liquid gasket, packing, oil seal or O-ring.
lDowel 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.
lThoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for
any restriction and blockage.
lAvoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust.
Before assembly, oil sliding surfaces well.
lRelease air within route when refilling after draining engine coolant.
lAfter repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and
exhaust systems for leakage.
Parts Requiring Angle TighteningEBS01E5M
lUse an angle wrench [SST: 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)
lDo not use a torque value for final tightening.
lThe torque value for these parts are for a preliminary step.
lEnsure thread and seat surfaces are clean and coated with engine oil.

Checking Drive BeltsEBS01EJ4
lBefore inspecting engine, make sure engine has cooled down; wait approximately 30 minutes after engine
has been stopped.
lVisually inspect all belts for wear, damage or cracks on contacting surfaces and edge areas.
lMeasure deflection at the marked point ( ).
CAUTION:
lWhen checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust to the specified value to avoid varia-
tion in deflection between pulleys.
lTighten idler pulley lock nut by hand and measure deflection without looseness.

Deflection AdjustmentEBS01EJ5
lAdjust belts with the parts shown below.
CAUTION:
lWhen a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.
lIf the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.
lWhen 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.
lMake sure the belts are fully fitted into the pulley grooves during installation.
lHandle with care to avoid smearing the belts with engine oil or engine coolant.
lDo not twist or bend the belts with strong force.
