12) Tighten countershaft front bearing nut to specified
torque while locking counter shaft in the same
manner as step 2) of “Disassembly” under
“Countershaft Disassembly and Assembly”.
CAUTION
!
Do not hold spline, gear teeth or abrasived
surface of shaft with vise through “V” blocks
or the like, otherwise shaft may be damaged.

kgf-m, 152.0 lb-ft)
13) Caulk countershaft front bearing nut using caulking
tool and hammer.
Countershaft and Reverse Idle Gear Inspection
S6JB0B5206026
• Using micrometer, check diameter of countershaft (1)
and needle bush (2) as shown. If measured value is
out of specification, replace counter and/or bush.
Countershaft diameter (standard)
• Measure width “a” of low speed gear shift fork and
groove width “b” of low speed gear synchronizer
sleeve and then calculate clearance “c” as follows:
If clearance exceeds limit, replace fork bush (1) and
sleeve.
Clearance “c” between fork and sleeve
Standard: 0.3 – 0.5 mm (0.012 – 0.020 in.)
Limit: 1.0 mm (0.039 in.)
• Check clearance “a” between synchronizer ring (2)
and gear (1), key slot width “b” in synchronizer ring
and each chamfered tooth of gear and synchronizer
ring and replace with new one, if necessary. Also,
check gear tooth.
Clearance “a” between synchronizer ring and
gear (Countershaft) (1st and 2nd)
Standard: 1.0 – 1.4 mm (0.040 – 0.055 in.)
Service limit: 0.5 mm (0.020 in.)
Key slot width “b” (1st and 2nd synchronizer ring)
Standard: 10.0 – 10.2 mm (0.394 – 0.401 in.)
Limit: 10.45 mm (0.411 in.)

• Using cylinder gauge (1), check inside diameter of
countershaft 1st and 2nd gears (2). If measured value
exceeds specification, replace countershaft 5th gear.
Countershaft 1st and 2nd gears diameter
Standard: 40.000 – 40.025 mm (1.5748 – 1.5757 in.)
• Check oil clearance between reverse idle gear (2) and
shaft (1) measuring inside diameter “a” of gear and
diameter “b” of shaft and calculate as follows:
If clearance exceeds limit, replace gear and shaft.
Oil clearance “c” between reverse idle gear and
shaft
Standard: 0.016 – 0.045 mm (0.0006 – 0.0018 in.)
Limit: 0.13 mm (0.005 in.)
• Check clearance between reverse idle gear (2) and
lever (1) of reverse gear shift link.
If clearance exceeds limit, replace gear and lever.
Clearance between reverse idle gear and lever
Standard: 0.05 mm – 0.35 mm (0.002 – 0.014 in.)
Limit: 0.5 mm (0.020 in.)
Output Shaft Disassembly and Assembly
S6JB0B5206027
Disassembly
1) Remove output shaft rear snap ring.
2) Apply bearing puller to output shaft front bearing (1),
and drive out output shaft front bearing, output shaft
gear (2) and output shaft rear bearing (3) all at once
from output shaft using press.
Assembly
1) Clean all components thoroughly, inspect them for
any abnormality and replace with new ones as
necessary.
2) Put front bearing (1) onto output shaft facing groove
(4) side to output shaft gear (2) and drive in output
shaft front bearing, output shaft gear and output
shaft rear bearing (3) all together using special tool
and hammer.
Special tool
(A): 09940–51710
3) Install new output shaft rear snap ring.
