ENGINE OVERHAUL -Timing Belt11B-14
REMOVAL SERVICE POINTS
AA"TIMING BELT REMOVAL
1. To ensure that the timing belt is assembled in the same
direction when reused, using chalk, etc., make an arrow
showing the rotation direction on the back surface of
the timing belt.
2. Position the exhaust camshaft sprocket’s timing mark by
approx. one tooth before the No. 1 cylinder compression
top dead centre.
Caution
When removed at the compression top dead centre,
since the exhaust camshaft is at the position pressing
down on the valve, the sprocket could rotate in reverse
due to the force of the valve spring creating a
hazardous situation.
3. Loosen the lock nut for the tensioner pulley, and remove
the timing belt.
AB"OIL PUMP SPROCKET REMOVAL
1. Remove the plug on the left side of the cylinder block.
2. Insert a Phillips driver (shaft diameter 8 mm) to stop the
counter balance shaft left from rotating.
3. Loosen the flange bolt.
4. Remove the oil pump sprocket.
AC"CRANKSHAFT BOLT REMOVAL
1. Fix the flywheel with the special tool.
2. Remove the crankshaft bolt.
AD"CRANKSHAFT SPROCKET REMOVAL
Use the special tool to remove the sprocket if it is stuck
and hard to remove.

Caution
(1) Measure when the belt’s surface temperature is
close to room temperature.
(2) Make sure that water or oil, etc., do not get on
the mike.
(3) If strong winds contact the mike or if noise is
generated in the area while measuring, a value
that differs from the actual value may be indicated.
(4) If the measurement is carried out with the mike
contacted against the belt, a value that differs
from the actual value may be indicated.
(5) Do not measure while the engine is running.
11. Disconnect MUT-II.
12. When measuring with the deflection amount, press the
centre of the tensed side of timing belt B with your index
finger in the arrow direction, and confirm that the deflection
is between 5 and 7 mm.

SPROCKET/CRANKSHAFT SENSING BLADE
INSTALLATION
1. Clean and degrease the crankshaft sprocket, crankshaft
sprocket installation surface of crankshaft and crankshaft
sensing blade, and then install the crankshaft sprocket
and crankshaft sensing blade.
2. Clean the crankshaft bolt hole section.
3. Apply the minimum required amount of engine oil on the
crankshaft bolt section and upper surface of the washer.
4. Fix the flywheel with the special tool.
5. Tighten the crankshaft bolt at the specified torque 162

PROBLEM SYMPTOMS TABLE (FOR YOUR INFORMATION)
ItemsSymptom
StartingWon’t startThe starter is used to crank the engine, but there is no combustion within the
cylinders, and the engine won’t start.
Fires up and diesThere is combustion within the cylinders, but then the engine soon stalls.
Hard startingEngine starts after cranking a while.
Idling
stability
HuntingEngine speed doesn’t remain constant; changes at idle.
stability
Rough idleUsually, a judgement can be based upon the movement of the tachometer
pointer, and the vibration transmitted to the steering wheel, shift lever, body, etc.
This is called rough idle.
Incorrect idle speedThe engine doesn’t idle at the usual correct speed.
Engine stall
(Die out)The engine stalls when the foot is taken from the accelerator pedal, regardless
of whether the vehicles is moving or not.
Engine stall
(Pass out)The engine stalls when the accelerator pedal is depressed or while it is being
used.
DrivingHesitation Sag“Hesitation” is the delay in response of the vehicle speed (engine speed) that
occurs when the accelerator is depressed in order to accelerate from the speed
at which the vehicle is now traveling, or a temporary drop in vehicle speed
(engine speed) during such acceleration.
Serious hesitation is called “sag”. (Refer to Fig. 1)
Poor accelerationPoor acceleration is inability to obtain an acceleration corresponding to the
degree of throttle opening, even though acceleration is smooth, or the inability
to reach maximum speed.
StumbleEngine speed increase is delayed when the accelerator pedal is initially
depressed for acceleration. (Refer to Fig. 2)
ShockThe feeling of a comparatively large impact or vibration when the engine is
accelerated or decelerated.
SurgeThis is repeated surging ahead during constant speed travel or during variable
speed travel.
KnockingA sharp sound like a hammer striking the cylinder walls during driving and which
adversely affects driving.
StoppingRun on
(“Dieseling”)The condition in which the engine continues to run after the ignition switch is
turned to “LOCK” (OFF) position. Also called “Dieseling”.

INSPECTION
Check the following points; replace the part if a problem is
found.
1. EXHAUST MANIFOLD CHECK
(1) Check for damage or cracking of any part.
(2) Using a straight edge and a feeler gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
Limit: 0.20 mm
2. TURBOCHARGER ASSEMBLY CHECK
(1) Visually check the turbine wheel and the compressor
wheel for cracking or other damage.
(2) Check whether the turbine wheel and the compressor
