Main Bearings InspectionS7RS0B1406038
General Information
• Service main bearings are available in standard size and 0.25 mm (0.0098 in.) undersize, and each of them
has 5 kinds of bearings differing in tolerance.
• Upper half of bearing (1) has oil groove (2) as shown in figure.
Install this half with o il groove to cylinder block.
• Lower half of bearing does not have an oil groove.
Visual Inspection
Check bearings for pitting, scratches, wear or damage.
If any malcondition is foun d, replace both upper and
lower halves. Never replace either half without replacing
the other half.
Main Bearing Clearance
NOTE
Do not rotate crankshaft while gauging
plastic is installed.

Check clearance by using ga uging plastic according to
the following procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.
3) Place a piece of gauging plastic (1) the full width of bearing (parallel to crankshaft) on journal, avoiding
oil hole. 4) Tighten main bearing cap No.1 bolts (a) and main
bearing cap No.2 bolts (b) gradually as follows.
a) Tighten bolts (“1” through “10”) to 30 N ⋅m (3.0
kgf-m, 22.0 lb-ft) according to numerical order in
the figure.
b) In the same manner as in Step a), tighten them to 50 N ⋅m (5.0 kgf-m, 36.5 lb-ft).
c) In the same manner as in Step a), retighten them to 60 °.
d) Tighten bolts (“11” through “18”) to 25 N ⋅m (2.5
kgf-m, 18.0 lb-ft) according to numerical order in
the figure.
Tightening torque
Main bearing cap No.1 bolt (a): 30 Nm (3.0
kgf-m, 22.0 lb-ft), 50 Nm (5.0 kgf-m, 36.5 lb-ft)
and then retighten by turning through 60°
Main bearing cap No.2 bolt (b): 25 N·m (2.5
kgf-m, 18.0 lb-ft)
5) Remove bearing caps and using scale (1) on gauging plastic envelop (2), measure gauging plastic
width at its widest point. If clearance exceeds its
limit, replace bearing. Always replace both upper
and lower inserts as a unit.
A new standard bearing may produce proper
clearance. If not, it will be necessary to regrind
crankshaft journal for use of 0.25 mm undersize
bearing.
After selecting new bearing, recheck clearance.
Main bearing clearance
Standard: 0.021 – 0.041 mm (0.0008 – 0.0016 in.)
Limit: 0.054 mm (0.0021 in.)

Front Wheel Alignment ConstructionS7RS0B2201002
Among factors for front wheel alignment, only toe setting
can be adjusted. Camber and caster are not adjustable.
Therefore, should camber or caster be out of
specification due to the damage caused by hazardous
road conditions or collision, whether the damage is in
body or in suspension should be determined and
damaged body should be repaired or damaged
suspension should be replaced.
Preliminary Checks Prior to Adjustment Front Wheel
Alignment
Steering and vibration complaints are not always the
result of improper wheel alignment. An additional item to
be checked is the possibility of tire lead due to worn or
improperly manufactured tires. “Lead” is the vehicle
deviation from a straight path on a level road without
hand pressure on the steering wheel. Refer to “Radial
Tire Lead / Pull Description in Section 2D” in order to
determine if the vehicle has a tire lead problem. Before
making any adjustment affecting wheel alignment, the
following checks and inspections should be made to
ensure correctness of alignment readings and alignment
adjustments:
• Check all tires for proper inflation pressures and approximately the same tread wear. • Check for loose of ball join
ts. Check tie-rod ends; if
excessive looseness is noted, it must be corrected
before adjusting.
• Check for run-out of wheels and tires.
• Check vehicle trim heights; if it is out of limit and a
correction is needed, it must be done before adjusting
toe.
• Check for loose of suspension control arms.
• Check for loose or missin g stabilizer bar attachments.
• Consideration must be given to excess loads, such as
tool boxes. If this excess load is normally carried in
vehicle, it should remain in vehicle during alignment
checks.
• Consider condition of equipment being used to check alignment and follow manufa cturer’s instructions.
• Regardless of equipment used to check alignment, vehicle must be placed on a level surface.
NOTE
To prevent possible incorrect reading of toe,
camber or caster, vehicle front and rear end
must be moved up and down a few times
before inspection.

Toe Inspection and Adjustment
Preparation for toe inspection and adjustment.
• Place vehicle in unloaded state on level surface.
• Set steering wheel in straight state.
• Check that inflation pressure of each tire is adjusted properly and wheel is free from deflection.
• Check that each suspension part is free from bend, dent, wear or damage in any other form.
• Check that ground clearance at the right and left is just about the same.

Radial Tire Lead / Pull DescriptionS7RS0B2401006
“Lead / Pull” is the deviation of the vehicle from a straight
path on a level road even with no pressure on the
steering wheel.
Lead is usually caused by the following conditions.
• Improper tire and wheel alignment.
• Uneven brake assemblies.
• Tire construction.
The way in which a tire is built can produce lead in a
vehicle. An example of this is placement of the belt. Off
center belts on radial tires can cause the tire to develop
a side force while rolling straight down the road. If one
side of the tire has a little larger diameter than the other,
the tire will tend to roll to one side. This will develop a
side force which can produce vehicle lead.
The procedure in the figure (Lead Diagnosis) should be
used to make sure that wheel alignment is not mistaken
for tire lead.
• Part of the lead diagnosis procedure is different from the proper tire rotation pattern currently in the owner
and service manuals. If a medium to high mileage tire
is moved to the other side of the vehicle, be sure to
check that ride roughness has not developed.
• Rear tires will not cause lead.
Balancing Wheels DescriptionS7RS0B2401007
There are two types of wheel an d tire balance: static and
dynamic. Static balance, as shown in figure, is the equal
distribution of weight around the wheel. Wheels that are
statically unbalanced cause a bouncing action called
tramp. This condition will eventually cause uneven tire
wear.
Dynamic balance, as shown in figure, is the equal
distribution of weight on each side of the wheel
centerline so that when the tire spins there is no
tendency for the assembly to move from side to side.
Wheels that are dynamically unbalanced may cause
shimmy.

Brake Fluid Level InspectionS7RS0B4106004
1) Check master cylinder, reservoir and reservoir hose (if equipped) for crack, damage and brake fluid
leakage. If any faulty condition exists, correct or
replace.
2) Check that brake fluid level is between MAX and MIN marks on reservoir.
NOTE
Be sure to use particular brake fluid either as
indicated on reservoir cap of that vehicle or
recommended in owner’s manual which
comes along with that vehicle. Use of any
other fluid is strictly prohibited.
Fluid level should be between MIN and MAX
lines marked on reservoir.
When brake warning lamp lights sometimes
during driving, replenis h fluid to MAX level.
When fluid decreases quickly, inspect brake
system for leakage. Correct leaky points and
then refill to specified level.

CAUTION!
Do not use shock absorber fluid or any other
fluid which contains mineral oil. Do not use a
container which has been used for mineral oil
or a container which is wet from water.
Mineral oil will cause swelling and distortion
of rubber parts in hydraulic brake system and
water mixed into brake fluid will lower fluid
boiling point. Keep all fluid containers
capped to prevent contamination.
