1987 SUZUKI GRAND VITARA wheel

3) Reinstall carburetor following normal service
procedures.
Connect emission control system hoses and
lead wires. Make specified play on accelerator
cable and refill cooling system.
4) Place transaxle gear shift lever in “Neutral”,
set parking brake and block drive wheels.
5) Start engine, and warm it up to normal
operating temperature, stop engine.
6) Be sure to check the following before idle
mixture adjustment.
l Fuel level is within round mark at the
center of level gauge.
l Valve lash is checked and adjusted accord-
ing to the maintenance schedule.
l Air cleaner has been properly installed
and is in good condition.
l All accessories (wipers, heater, lights etc)
are out of service.
l Ignition timing is within specification.
l Choke valve opens fully.
l Idle-up actuator does not operate.
7) Check and adjust idle speed to specification
if necessary.
8) Remove seal rubber of duty check coupler
and connect positive terminal of duty
meter to“Blue/Red” wire and negative
terminal to “Black/Green” wire.
9) Run engine at 1,500 - 2,000 r/min for 30
seconds and bring it to idle speed.
10) With engine running at idle speed, adjust idle
mixture adjusting screw slowly in small incre-
ment allowing time for duty to stabilize after
turning screw to obtain duty of 10 - 50.
If duty is too low, back screw out; if too
high, screw it in. After obtaining duty of
10 - 50, recheck idle speed, and adjust if
necessary.
NOTE:
If adjustment can’t be made because duty meter
indicator does not deflect, check feed back
system according to the checking procedure of
system described in section of Emission Control
System.
11) After adjustment, install seal rubber to duty
check coupler and drive in idle mixture
adjusting screw pin.

light (should not flash).
If it does not light, check electric circuit of
the light, namely light for blow off and lead
wire for disconnection.
Fig. 5-3- 16 “CHECK ENGINE” light
3) After lighting of the light is confirmed, start
engine and warm it up to normal operating
temperature.
4) When engine is warmed up, run engine at
1,500- 2,000 rpm. In this state, make sure
that “CHECK ENGINE”lightflashes. Flashing
of light proves that system is in good condition.
If light does not flash, it can be caused by
one of the following. Check them and replace
or adjust as necessary.
l Defective thermal switch
l Disconnected or loosely connected electric
lead wires of emission control systems
l Defective ECM
l Defective micro switches (idle and wot)
5)After making sure that “CHECK ENGINE”
light flashes, turn cancel switch OFF. Light
should go off.
6) Stop engine.
Checking idle and wide open micro switches
Check idle and wide open micro switches
according to the following procedures.
1. Warm up engine to normal operating tempe-
rature and stop engine.
2. For this check, use check terminal coming
from the lower right of instrument panel as
shown.
Connect negative prod of ohmmeter to check
terminal and positive prod to body.

Ignition Timing
Ignition timing10” BTDC at
800 * 50 r/min
1 Ignition orderIl-3-4-2I
When checking and adjusting ignition timing,
be sure to use timing light (09900-27301 or
09900-27311).
NOTE:
Prior to check and adjustment of ignition timing,
make sure that head lights, heater fan, rear
defogger (if equipped), and air conditioner (if
equipped) are “OFF”. If any one of these
systems is “ON”,idle up system operates and
engine idle speed will be out of the specification.
[Checking]
1. Remove rubber plug from timing check
window on the transmission case.
2. Start engine and warm it up to normal operat-
ing temperature.
3. After warming up, check to be sure that idle
speed is within specification. If idle speed is
out of specification, adjust it by turning
idle speed adjusting screw of carburetor.
4. Connect timing light to high tension cord of
No. 1 cylinder.
5. With engine running at specified idle speed,
direct the timing light to timing check win-
dow. If 10” BTDC timing mark@on flywheel
appears aligned to timing match mark @ ,
ignition is properly timed.
Fig. 8-20
[Adjusting]
lf ignition timing is out of specification, adjust
it.
Loosen distributor flange bolt and turn distri-
butor housing in place to advance or retard
timing.
Turning housing counterclockwise advances
timing, and vice versa. After adjustment, tighten
flange bolt and recheck timing.

2. Timing is retarded
3. Timing is advanced
Be sure to re-install check window rubber plug
after making above check and adjustment.
WARNING:
When engine is warmed up, exhaust mani-
fold cover and other parts are hot as well.
Be careful not to touch them when remov-
ing and reinstalling rubber plug.
[Checking centrifugal advancer]
After removing distributor cap, turn rotor
clockwise by finger and release it
Check that rotor returns smoothly counterclock-
wise by spring force.
If defective, replace distributor.

INSTALLATIONDistributor
When re-installing distributor, be sure to insertit into distributor gear case in the following
sequence:
1. Turn over crankshaft in normal direction (clockwise as viewed from crankshaft pulley
side) until specified timing mark @on flywheel aligns with timing match mark
0.
CAUTION :
After aligning two marks, remove cylinder
head cover to visually confirm that rocker
arms are not riding on camshaft cams at
No. 1 cylinder. If arms are found to be
riding on cams, turn over crankshaft 360”
to align two marks anew.

5. Distribute cords as shown in figure. Securely
connect cords to distributor cap terminals and
spark plugs.
NOTE:
Make sure to clamp high tension cords so that
they do not contact other parts.

Fig. 9 1 Cranking circuit
CRANKING CIRCUIT
The cranking circuit consists of the battery, starting motor, ignition switch, clutch switch and related
electrical wiring. These components are connected electrically as shown in Fig. 9-l. Only the starting
motor will be covered in this portion.
STARTING MOTOR
The starting motor consists of parts shown in Fig. 9-2 and has field coils mounted in starting motor yoke
(frame).
The magnetic switch assembly and parts in the starting motor are enclosed in the housings so that they
will be protected against possible dirt and water splash.
In the circuit shown in Fig. 9-1, the magnetic (motor) switch coils are magnetized when the ignition
switch is closed. The resulting plunger and pinion drive lever movement causes the pinion to engage the
engine flywheel gear and the magnetic switch main contacts to close, and cranking takes place. When the
engine starts, the pinion overrunning clutch protects the armature from excessive speed until the switch
is opened, at which time the return spring causes the pinion to disengage.

11-l. GENERAL DESCRIPTIONThe clutch is a diaphragm-spring clutch of a dry single disc type. The diaphragm spring is of a tapering-
finger type, which is a solid ring in the outer diameter part, with a series of tapering fingers pointing
inward. The disc, carrying four torsional coil springs, is slidably mounted on the transmission input shaft
with a serration fit.
The clutch cover is secured to the flywheel, and carries the diaphragm spring in such a way that the
peripheral edge of the spring pushes on the pressure plate against the flywheel (with the disc in between),
when the clutch release bearing is held back: Tnis is the engaged condition of the clutch.
Depressing the clutch pedal causes the release bearing to advance and push on the tips of the tapering
fingers of the diaphragm spring. When this happens, the diaphragm spring pulls the pressure plate away
from the flywheel, thereby interrupting the flow of drive from flywheel through clutch disc to trans-
mission input shaft.
