1. Remove case cover.
2. Remove mainshaft bearing snap ring.
3. Remove transmission case while slightly tilting it to prevent 5th
shift fork from interfering with case.
4. Draw out reverse idler spacer and fork shaft.
5. Remove 5th and 3rd & 4th shift forks.
IBe careful not to lose shifter cap.

6. Remove control bracket with 1st & 2nd shift fork.
7. Remove gear components from clutch housing.
a. Remove input shaft front bearing retainer securing bolts.
b. Remove input shaft with bearing retainer, mainshaft assembly
and reverse idler gear.
IAlways withdraw mainshaft straight out. Failure to do so
can damage resin oil channel on clutch housing side.
IDo not draw out reverse idler shaft from clutch housing
because these fittings will be loose.
When removing input shaft, be careful not to scratch oil
seal lip with shaft spline.
c. Remove final drive assembly.
8. Remove oil pocket, shift check ball, check spring and check
ball plug.
IBe careful not to lose check ball.

9. Drive retaining pin out of striking lever, then remove striking
rod, striking lever and striking interlock.
IEnsure striking lever is positioned so that retaining pin
does not foul clutch housing during removal.
IBe careful not to damage oil seal lip, when removing strik-
ing rod. If necessary, tape edges of striking rod.
10. Remove reverse check plug, then detach reverse check spring
and check balls.
IBe careful not to lose check balls.
IIf the smaller ball does not come out, remove it together
with check sleeve assembly.
11. Remove check sleeve assembly.

DISASSEMBLY
1. Before disassembly, check 5th input gear end play.
Gears End play mm (in)
5th input gear0.18 - 0.31 (0.0071 - 0.0122)
IIf not within specification, disassemble and check contact sur-
face of gear, shaft and hub. Then check clearance of snap ring
groove Ð Refer to ªAssemblyº.
2. Remove snap ring and 5th stopper.
3. Remove 5th synchronizer, 5th input gear and 5th gear needle
bearing.
4. Remove snap ring of input shaft front bearing and input gear
spacer.

5. Pull out input shaft front bearing.
6. Remove bearing retainer.
INSPECTION
Gear and shaft
ICheck shaft for cracks, wear or bending.
ICheck gears for excessive wear, chips or cracks.
Synchronizer
ICheck spline area of coupling sleeves, hubs and gears for
wear or cracks.
ICheck baulk rings for cracks or deformation.
ICheck insert springs for wear or deformation.
IMeasure clearance between baulk ring and gear.
Clearance between baulk ring and 5th input gear:
Standard
1.0 - 1.35 mm (0.0394 - 0.0531 in)
Wear limit
0.7 mm (0.028 in)
Bearing
lMake sure bearings roll freely and are free from noise, cracks,
pitting or wear.

ASSEMBLY
1. Assemble 5th synchronizer.
IBe careful not to hook front and rear ends of spread
spring to the same shifting insert.
2. Install bearing retainer.
3. Press on input shaft front bearing.
4. Install input gear spacer.
5. Select correct snap ring of input shaft front bearing to minimize
clearance of groove in input shaft and then install it.
Allowable clearance of groove:
0 - 0.1 mm (0 - 0.004 in)
Snap rings of input shaft front bearing:
Refer to SDS, MT-87.
6. Install 5th gear needle bearing, 5th input gear, 5th synchro-
nizer and 5th stopper.
7. Measure gear end play as a final check Ð Refer to ªDisassem-
blyº.
