PRECAUTIONS
[YD22DDTi]PRECAUTIONSPFP:00001
Precautions for Drain 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.
●Release fuel pressure before disassembly.
●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.
●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 Angular TighteningEBS00LR4
●Use an angle wrench 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 angular
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.

Checking Drive BeltsEBS00LRA
●Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the 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 the 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 value specified 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 cooling water etc.
●Do not twist or bend the belts with strong force.

EXHAUST MANIFOLD AND TURBOCHARGER
Turbocharger
EBS00LRJ
CAUTION:
When the compressor wheel turbine wheel or rotor shaft is damaged, remove all the fragments and
foreign matter left in the following passages in order to prevent a secondary failure:
ROTOR SHAFT CLEARANCE
●Check that the rotor shaft rotates smoothly without any resis-
tance when it is rotated by your fingertips.
●Check that the rotor shaft is not loose when it is moved vertically
or horizontally.
Measure looseness with a dial gauge inserting its measuring rod
through oil drain hole of turbocharger.
ROTOR SHAFT END PLAY
Place a dial gauge at the rotor shaft end in the axial direction to mea-
sure the end play.

EXHAUST MANIFOLD AND TURBOCHARGER
TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:
●Check that the engine oil level is between MIN and MAX of the dipstick. (When the engine oil amount is
more than MAX, the engine oil flows into the inlet duct through the blow-by gas passage, and the turbo-
charger is misjudged failure.)
●Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after
driving.
●Replace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.
●If no malfunction is found after the unit inspections, judge that the turbocharger body has no failure. Check
the other parts again.
