Main Bearings
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 bear-
ings differing in tolerance.

Upper half of bearing (2) has oil groove (3) as shown in figure.
Install this half with oil groove to cylinder block (1).

On each main bearing cap, arrow mark and number are em-
bossed as shown in figure.
When installing each bearing cap to cylinder block, point arrow
mark toward crankshaft pulley side and install each cap from that
side to flywheel side in ascending order of numbers “1”, “2”, “3”,
“4” and “5”. Tighten cap bolts to specified torque.
Inspection
Check bearings for pitting, scratches, wear or damage.
If any malcondition is found, replace both upper and lower halves.
Never replace one half without replacing the other half.
Main bearing clearance
Check clearance by using gaging plastic (1) according to the follow-
ing procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.
3) Place a piece of gaging plastic to full width of bearing (parallel
to crankshaft) on journal, avoiding oil hole.
4) Install bearing cap as previously outlined and evenly toque cap
bolts to specified torque.
Bearing cap MUST be torqued to specification in order to assure
proper reading of clearance.
Tightening Torque
(a): 54 N
.m (5.4 kg-m, 39.0 lb-ft)
NOTE:
Do not rotate crankshaft while gaging plastic is installed.

WARNING:
For vehicles equipped with a Supplemental Inflatable Restraint Air Bag System:

Service on or around Air Bag System Components or Wiring must be performed only by an authorized
Suzuki dealer. Please observe all WARNINGS and SERVICE PRECAUTIONS in Section 9J under “On-
Vehicle Service” and the Air Bag System Component and Wiring Location view in Section 9J before
performing service on or around Air Bag System Components or Wiring. Failure to follow WARNINGS
could result in unintended air bag deployment or could render the air bag inoperative. Either of these
two conditions may result in severe injury.

SDM can maintain sufficient voltage to cause a deployment of air bags for up to 15 seconds after igni-
tion switch is turned to “LOCK” position, battery is disconnected or fuse powering SDM is removed.
Work must be started after 15 seconds from the time.
NOTE:
For the descriptions for vehicle without warm up three way catalytic converter (WU TWC), refer to the same
section of the Service Manual mentioned in the FOREWORD of this manual.

ON-VEHICLE SERVICE
GENERAL
When the hoses have been disconnected and system’s component
removed for service, be sure to reinstall component properly, and
route and connect hoses correctly after service. Refer to Emission
Control Information Label for proper connection of hoses (if
equipped).
ACCELERATOR CABLE ADJUSTMENT
1) Confirm that ambient temperature is higher than 0C, 32F.
2) Warm up engine to normal operating temperature with all elec-
tric loads OFF and stop engine.
3) Confirm that clearance “c” between throttle lever (1) and stop
screw (2) is less than about 1 mm (0.04 in.).
4) Check accelerator cable for play.
Accelerator cable play “a”: 10 – 15 mm (0.4 – 0.6 in.)
Cable play should be within specification. If out of specification,
loosen accelerator cable lock nut and adjust by turning adjusting
nut (3). Be sure to tighten lock nut (4) securely after adjustment.
5) With accelerator pedal depressed fully, check clearance be-
tween throttle lever and lever stopper (5) (throttle body) which
should be within following specification.
Clearance “b”: 0.5 – 2.0 mm (0.02 – 0.07 in.)
(With pedal depressed fully)
If measured value is out of specification, adjust it to specification
by changing height of pedal stopper bolt (6).
IDLE SPEED INSPECTION
Before inspecting idle speed, make sure to the following.

Lead wires and hoses of Electronic Fuel Injection and engine
emission control systems are connected securely.

After warming up engine, accelerator cable has some play, that
is, it is not tight.

Ignition timing is within specification.

All of electrical loads except ignition are switched off.

Air cleaner has been properly installed and is in good condition.

Malfunction indicator lamp does not light when engine running.
After above items are all confirmed, check idle speed as follows.

WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
