2. Reinstall mainshaft rear bearing outer race without shims.
3. Clean mating surfaces of clutch housing and transmission
case with solvent.
4. Install mainshaft and mainshaft front bearing outer race into
transmission case. Turn mainshaft while holding bearing outer
race so that bearings are properly seated.
SMT078A
SMT079A
5. Put straightedge [width must be more than 50 mm (1.97 in)] on
transmission case, and measure the distance from upper sur-
face of straightedge to surface of the bearing outer race using
a depth micrometer.
Measure at three places on bearing outer race, and take
the average.
6. Determine dimension A to be used by the following equation.
Dimension A = Width of straightedge − measured dis-
tance
7. Measure the distance from mating surface of clutch housing to
portion with which mainshaft front bearing outer race is to be
mated.
Measure at three places on the portion, and take the aver-
age.
Dimension B = Measured distance
8. Determine dimension C to be used by the following equation.
Dimension “C” = B − A
9. Determine total thickness of shims with SDS table as a guide.
Mainshaft bearing adjusting shim:
Refer to SDS, MT-134.
10. Install selected mainshaft bearing adjusting shim and main-
shaft bearing outer race.
11. Check total turning torque after assembly — Refer to
“ASSEMBLY”, MT-114.

18. If bearing preload of mainshaft was adjusted, install selected
shim(s) into transmission case.
To aid in installation of transmission case, place shift
selector in the 1st and 2nd shift bracket or between 1st
and 2nd bracket and 3rd and 4th bracket.
19. Apply sealant to mating surface of transmission case and
install it. Refer to “Case Components”, MT-92.
20. Install PNP switch.
SMT626D
21. Apply sealant to threads of check plugs. Install balls, springs
and plugs. Refer to “Shift Control Components”, MT-94.
22. After assembly, check that you can shift into each gear
smoothly.

23. Measure total turning torque.
Total turning torque (New bearing):
8.8 - 21.6 N·m (90 - 220 kg-cm, 78 - 191 in-lb)
When old bearing is used again, preload will be slightly
less than the above. Make sure torque is close to the
specified range.

●*1: Operates when overdrive control switch is set in “OFF” position.
●*2: Oil pressure is applied to both 2nd “apply” side and 3rd “release” side of band servo piston. However, brake band does not con-
tract because oil pressure area on the “release” side is greater than that on the “apply” side.
●*3: Oil pressure is applied to 4th “apply” side in condition *2 above, and brake band contracts.
●*4: A/T will not shift to 4th when overdrive control switch is set in “OFF” position.
●*5: Operates when overdrive control switch is “OFF”.
●: Operates.
●A: Operates when throttle opening is less than 3/16, activating engine brake.

OVERALL SYSTEM
POWER TRANSMISSION
“N” and “P” Positions
●“N” position
Power from the input shaft is not transmitted to the output shaft because the clutches do not operate.
●“P” position
Similar to the “N” position, the clutches do not operate. The parking pawl engages with the parking gear to
mechanically hold the output shaft so that the power train is locked.
