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
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” 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).

7A-2 MANUAL TRANSMISSION
GENERAL DESCRIPTION
CONSTRUCTION AND SERVICING
The transmission provides five forward speeds and one reverse speed by means of three synchronizers and
three shafts-input shaft, countershaft and reverse gear shaft. All forward gears are in constant mesh, and
reverse uses a sliding idler gear arrangement.
The low speed synchronizer is mounted on counter shaft and engaged with counter shaft first gear or second
gear, while the high speed synchronizer is done on input shaft and engaged with input shaft third gear or fourth
gear.
The fifth speed synchronizer on input shaft is engaged with input shaft fifth gear mounted on the input shaft.
The double cone synchronizing mechanism is provided to 2nd gear synchromesh device for high performance
of shifting to 2nd gear.
The countershaft turns the final gear and differential assembly, thereby turning the front drive shafts which are
attached to the front wheels.
4WD model is equipped with transfer assembly on transmission being mated to right side of differential output in
transmission.
For servicing, it is necessary to use genuine sealant or its equivalent on mating surfaces of transmission case
which is made of aluminum. The case fastening bolts must be tightened to specified torque by means of torque
wrench. It is also important that all parts are thoroughly cleaned with cleaning fluid and air dried before reas-
sembling.
Further, care must be taken to adjust preload of counter shaft taper roller bearings. New synchronizer rings are
prohibited from being lapped with respective gear cones by using lapping compound before they are assembled.

18) Remove engine left mounting (1) with bracket (2).
19) Remove other attached parts from transmission, if any.
20) Pull transmission out so as to disconnect input shaft from
clutch disc and then lower it.
REMOUNTING
Remount transmission in reverse order of dismounting procedure
noting the following.
 Refer to Section 7D for installing transfer (if equipped).
 Refer to the first figure of “UNIT REPAIR OVERHAUL” for
fastener specified torque.
 Push in drive shaft joints (right & left) fully so as to snap ring
of shaft engages with differential gear.
 Set each clamp for wiring securely.
 After connecting clutch cable, be sure to adjust its play prop-
erly.
Refer to Section 7C.
 Fill transmission with oil as specified.
 Connect battery and check function of engine, clutch and
transmission.
UNIT DISASSEMBLY
FIFTH GEARS
1) Remove side cover bolts and take off transmission side
cover.
CAUTION:
Care should be taken not to scratch oil seal lip with drive
shaft while raising transmission.
Do not hit drive shaft joint with hammer when installing it
into differential gear.
CAUTION:
Care should be taken not to distort side cover when it is
removed from left case.

MANUAL TRANSMISSION 7A-23
INSPECTION AND REASSEMBLY
1) Clean all components thoroughly, inspect them for any
abnormality and replace with new ones as necessary.
2) If synchronizer parts need to be repaired, check clearance
“a” between ring (2) and gear (1), each chamfered tooth of
gear, ring and sleeve, then determine parts replacement.
Clearance between synchronizer ring and gear
Standard “a” : 1.0 – 1.4 mm (0.039 – 0.055 in.)
Service limit “a” : 0.5 mm (0.019 in.)
3) To ensure lubrication, air blow oil holes (1) and make sure
that they are free from any obstruction.
4) Fit high speed synchronizer sleeve (4) to hub (3), insert 3
keys (2) in it and then set springs (1) as shown in figure.
Synchronizer key installation position
: A = B
5) Drive in right bearing (1) to input shaft (2) by using special
tool and hammer.
Special tool
(A) : 09913-80112
NOTE:
 No specific direction is assigned to each key but it is
assigned as sleeve & hub assembly.
 Size of high speed synchronizer sleeve, hub, keys and
springs is between those of low speed and 5th speed
ones.
[A] : 3rd gear side
C : Long flange
D : Key way
E : Projecting end

7A-26 MANUAL TRANSMISSION
8) Remove right bearing cone (2) by using puller (3), metal stick
(1) and press.
INSPECTION AND REASSEMBLY
1) Clean all components thoroughly, inspect them for any
abnormality and replace with new ones as necessary.
2) If synchronizer parts need to be repaired, check clearance
“a” between ring (2) and gear (1), each chamfered tooth of
gear, ring and sleeve, then determine parts replacement.
Clearance between synchronizer ring and gear
Standard “a” : 1.0 – 1.4 mm (0.039 – 0.055 in.)
Service limit “a” : 0.5 mm (0.019 in.)
3) Put the synchronizer outer ring (1), inner ring (3) and the
cone (2) together and then measure the step difference
between the outer ring and the inner ring. And also check
each chamfered tooth of gear and synchronizer ring and
replace with new one, if necessary. Also, check gear tooth.
Difference between synchronizer outer ring and inner ring
Standard “b” : 1.0 – 1.4 mm (0.039 – 0.055 in.)
Service limit “b” : 0.5 mm (0.019 in.)
4) To ensure lubrication, air blow oil holes (1) and make sure
that they are free from any obstruction.
