remove shim (3).
WARNING!
Never put in the hand between camshaft and
tappet.

5) Using a micrometer (2), measure the thickness of
the removed shim (1), and determine replacement
shim by calculating the thickness of new shim with
the following formula and table.
Shim thickness specification
Intake side:
A = B + C – 0.20 mm (0.008 in.)
Exhaust side:
A = B + C – 0.30 mm (0.012 in.)
A: Thickness of new shim
B: Thickness of removed shim
C: Measured valve clearance
For example of intake side:
When thickness of removed shim is 2.40 mm (0.094
in.), and measured valve clearance is 0.45 mm
(0.018 in.).
A = 2.40 mm (0.094 in.) + 0.45 mm (0.018 in.) – 0.20
mm (0.008 in.) = 2.65 mm (0.104 in.)

Selection of Connecting Rod Bearings
NOTE
• If bearing is in malcondition, or bearing
clearance is out of specification, select a
new standard bearing according to the
following procedure and install it.
• When replacing crankshaft or connecting
rod and its bearing due to any reason,
select new standard bearings to be
installed by referring to numbers stamped
on connecting rod and its cap and/or
alphabets stamped on crank web of No.3
cylinder.

1) Check stamped numbers on connecting rod and its
cap as shown.
Three kinds of numbers (“1”, “2” and “3”) represent
the following connecting rod big end inside
diameters.
For example, stamped number “1” indicates that
corresponding connecting rod big end inside
diameter is 45.000 – 45.006 mm (1.7717 – 1.7718
in.).

Selection of Main Bearings
Standard bearing
If bearing is in malcondition, or bearing clearance is out
of specification, select a new standard bearing according
to the following procedure and install it.
1) First check journal diameter. As shown in figure,
crank web No.2 has stamped numbers.
Three kinds of numbers (“1”, “2” and “3”) represent
the following journal diameters.
Stamped numbers on crank web No.2 represent
journal diameters marked with an arrow in figure
respectively. For example of M15 engine, stamped
number “1” indicates that corresponding journal
diameter is 51.9940 – 52.0000 mm (2.0471 – 2.0472
in.).
Crankshaft journal diameter2) Next, check bearing cap bore diameter without
bearing. On mating surface of cylinder block, five
alphabets are stamped as shown in figure.
Three kinds of alphabets (“A”, “B” and “C”) or
numbers (“1”, “2” and “3”) represent the following
cap bore diameters.
Stamped alphabets or numbers on cylinder block
represent bearing cap bore diameter marked with an
arrow in figure respectively.
For example, stamped “A” or “1” indicates that
corresponding bearing cap bore diameter is 56.0000
– 56.0060 mm (2.2048 – 2.2049 in.).

Precautions
Precautions on Fuel System ServiceS6RW0D1700001
WARNING!
Before attempting service of any type on fuel system, the following should be always observed in
order to reduce the risk of fire and personal injury.
• Disconnect negative cable at battery.
• Do not smoke, and place no smoking signs near work area.
• Be sure to have CO
2 fire extinguisher handy.
• Be sure to perform work in a well-ventilated area and away from any open flames (such as gas hot
heater).
• Wear safety glasses.
• To relieve fuel vapor pressure in fuel tank, remove fuel filler cap from fuel filler neck and then
reinstall it.
• As fuel feed line is still under high fuel pressure even after stopping engine, loosening or
disconnecting fuel feed line directly may cause dangerous spout of fuel. Before loosening or
disconnecting fuel feed line, make sure to relieve fuel pressure referring to “Fuel Pressure Relief
Procedure”.
• A small amount of fuel may be released when the fuel line is disconnected. In order to reduce the
risk of personal injury, cover a shop cloth to the fitting to be disconnected. Be sure to put that cloth
in an approved container after disconnecting.
• Never run engine with fuel pump relay disconnected when engine and exhaust system are hot.
• Note that fuel hose connection varies with each type of pipe. Be sure to connect and clamp each
hose correctly referring to “Fuel Hose Disconnecting and Reconnecting”.
After connecting, make sure that it has no twist or kink.
• When installing injector or fuel feed pipe, lubricate its O-ring with gasoline.
• When servicing the fuel tank, it should be treated with respect, with no contact with sharp edges or
hot surfaces. In addition, the fuel tank should not be dropped since fuel tank, fuel pump and other
components can be damaged by the impact. If dropped, all components should be replaced because
there is a risk of damage.
• The fuel tank is made of resin.
Be sure not to allow solvent (chemical article such as grease and sealant) to attach to the fuel tank
as some chemical reaction may occur, causing the fuel tank to be swollen, hardened or distorted
leakage and resulting in fuel leakage from the fuel tank.

Care of battery
WARNING!
• Never expose battery to open flame or electric spark because of battery generate gas which is
flammable and explosive.
• Do not allow battery fluid to contact eyes, skin, fabrics, or painted surfaces as fluid is a corrosive
acid. Flush any contacted area with water immediately and thoroughly.
• Batteries should always be kept out of reach of children.

1) The battery is a very reliable component, but needs periodical attentions.
• Keep the battery carrier clean.
• Prevent rust formation on the terminal posts.
• Keep the electrolyte up to the upper level uniformly in all cells.
• When keeping battery on vehicle over a long period of time, follow instructions given below.
– Weekly, start the engine and run it until it reaches normal operating temperature with engine speed of 2000 to
3000 rpm. Make sure all electric switches are off before storing the vehicle.
– Recharge the battery twice a month to prevent it from discharging excessively. This is especially important
when ambient temperature is low.
The battery discharges even when it is not used, while vehicles are being stored. Battery electrolyte can
freeze and battery case can crack at cold ambient condition if battery is not properly charged.
2) Keep the battery cable connections clean.
The cable connections, particularly at the positive (+) terminal post, tend to become corroded. The product of
corrosion, or rust, on the mating faces of conductors resists the flow of current.
Clean the terminals and fittings periodically to ensure good metal-to-metal contact, and grease the connections
after each cleaning to protect them against rusting.
3) Be always in the know as to the state of charge of the battery. The simplest way to tell the state of charge is to
carry out a hydrometer test. The hydrometer is an instrument for measuring the specific gravity (S.G.) of the
battery electrolyte. The S.G. of the electrolyte is indicative of the state of charge. Refer to “Battery Inspection”.

3) Install bump stopper and strut dust cover onto strut
rod. For installing direction, refer to the figure in
“Front Strut Assembly Components”.
4) Pull strut rod as far up as possible and use care not
to allow it to retract into strut.
5) Install spring seat on coil spring and then spring
upper seat (1) aligning “OUT” mark (3) on spring
upper seat and center of strut bracket (2).
6) Install bearing (3), strut support (2) and strut support
lower nut (1) in this sequence.
Tighten strut support lower nut (1) to specified
torque.
When tightening strut support lower nut, hold stud
with hexagon wrench.
Tightening torque
Strut support lower nut (a): 55 N·m (5.5 kgf-m,
40.0 lb-ft)Front Strut Assembly CheckS6RW0D2206005
• Inspect strut for oil leakage, damage or deformation.
If defect is found, replace strut as an assembly unit,
because it can not be disassembled.
• Inspect strut function referring to the following
procedures:
1) Check and adjust tire pressures as specified.
2) Bounce vehicle body up and down 3 or 4 times
continuously by pushing front end of the vehicle side
body to check strut.
Also, note how many times vehicle body rebounds to
stop after force application.
3) Repeat the same procedure to the other strut to
confirm that the both side struts equally respond.
If conditions of struts are in doubt, compare them with
known-good vehicle or strut.
• Inspect bearing for wear, abnormal noise or gripping.
If defective, replace.
• Inspect coil spring seat for cracks or deformation.
If defective, replace.
• Inspect bump stopper for deterioration.
If defective, replace.
• Inspect rebound stopper and strut mount for wear,
cracks or deformation.
If defective, replace.
