REMOVAL
1. Drain engine coolant from radiator. Refer to CO-11, "Changing Engine Coolant".
CAUTION:
Perform this step when the engine is cold.
Never spill engine coolant on drive belts.
2. Steer front wheel to the right.
3. Remove front fender protector (RH). Refer to EXT-22, "

ENGINE RUNNING
No work should be carried out on the hydraulic system while engine is running.
Remember that fuel pressure values in hydraulic circuit can reach up to 1,600 bar.
Keep hands or face (particularly eyes) out of any high pressure leak.
Recall that fuel is dangerous for health.
FUEL RAIL PRESSURE SENSOR
Under warranty, do not remove the fuel rail pressure sensor from the rail.
Do not try to measure the resistance of the fuel rail pressure sensor. This test is destructive for the
internal components.
FUEL INJECTOR
Fuel injectors are driven by over 100V.
FUEL injector electronics are polarised. In case of intervention on wiring harness, do not
invertwires. It is destructive for the piezo components.
Do not drive the fuel injectors if their body is not connected to the battery ground (risk ofelectro-
static discharge). For instance, fuel injector body have to be in contact with cylinder.
Piezo fuel injector connector must not be unplugged while engine is running. Risk of majordamage
to the engine (fuel injector could stay opened).
CleanlinessINFOID:0000000001162747
Cleanliness
RISKS ASSOCIATED WITH CONTAMINATION
The high pressure direct injection system is highly sensitive to contamination. The risks associated withcon-
tamination are:
damage to or destruction of the high pressure injection system,
components jamming,
components losing seal integrity.
All After-Sales operations must be performed under very clean conditions. This means that no impurities (par-
ticles a few microns in size) should have entered the system during dismantling.
The cleanliness principle must be applied from the filter to the fuel injectors.
What are the sources of contamination?
metal or plastic chips,
paint,
fibres:
- from cardboard,
- from brushes,
- from paper,
- from clothing,
- from cloths,
foreign bodies such as hair,
ambient air
etc.
NOTE:
Cleaning the engine using a high pressure washer is prohibited because of the risk of damaging connections.
In addition, moisture may collect in the connectors and create electrical connection malfunction.

rotated.
4. Perform the necessary repair operation.
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 all control units using CONSULT-II.
Precaution for Drain CoolantINFOID:0000000001527635
Drain coolant when engine is cooled.
Precaution for Disconnecting Fuel PipingINFOID:0000000001527636
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:0000000001527637
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 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. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and ReplacementINFOID:0000000001527638
Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and InstallationINFOID:0000000001527639
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.
Parts Requiring Angular TighteningINFOID:0000000001527640
Use an angle wrench for the final tightening of the following engine parts:
- Cylinder head bolts
- Camshaft sprocket (INT)
- 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. Tool number : KV10112100 (BT-8653-A)

CheckingINFOID:0000000001381384
Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
Visually check belts for wear, damage, and cracks on inside and
edges.
Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
When the tension and frequency are measured, the acoustic tension gauge should be used.
When checking 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 variation in deflection
between pulleys.
Tension AdjustmentINFOID:0000000001381385
CAUTION:
When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
When installing a belt, make sure it is correctly engaged with the pulley groove.
Never allow oil or engine coolant to get on the belt.
Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.
