Temporarily install the output shaft, new rear output shaft bearing shim, output shaft spacer, rear output shaft bearing and a new manual transmission output shaft rear set nut to the rear transmission case sub-assembly.
Note
Do not apply gear oil to a new output shaft bearing and rear output shaft bearing. If applied, the turning torque cannot be accurately measured.
If the turning torque is not properly measured, the output shaft bearing may generate abnormal noise and become damaged.
| *a | Hold |
| *b | Turn |
| *c | Fulcrum Length |
Temporarily install the manual transmission output shaft rear set nut to the output shaft.
Note
If the nut is not temporarily installed, the position of the rear output shaft bearing will be unstable causing the preload to be unstable.
| *a | Hold |
| *b | Turn |
| *c | Fulcrum Length |
Using SST and a torque wrench, tighten the manual transmission output shaft rear set nut.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
When using SST (fulcrum length of 50 mm (1.9685 in.)) + torque wrench (fulcrum length of 1055 mm (41.5354 in.)): 178.5 N*m (1820 kgf*cm, 132 ft.*lbf)
| *a | Fulcrum Length |
Using SST and a torque wrench, measure the turning torque of the output shaft bearing while rotating SST at 60 rpm.
| Standard turning torque at 60 rpm |
|---|
| New output shaft bearing |
| 0.21 to 1.32 N*m (2.14 to 13.46 kgf*cm, 1.86 to 11.68 in.*lbf) |
Note
Do not apply gear oil to a new output shaft bearing and rear output shaft bearing. If applied, the turning torque cannot be accurately measured.
If the turning torque is not properly measured, the output shaft bearing may generate abnormal noise and become damaged.
Tech Tips
Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.
New output shaft bearing:
When using SST (fulcrum length of 50 mm (1.969 in.)) + torque wrench (fulcrum length of 160 mm (6.299 in.)): 0.16 to 1.00 N*m (1.64 to 10.19 kgf*cm, 1.42 to 8.85 in.*lbf)
If the torque is more than the standard, replace the output shaft shim.
Tech Tips
New output shaft bearing:
When the thickness of the shim is increased by 0.016 mm (0.0006 in.), the preload is reduced by 0.45 N*m (4.59 kgf*cm, 3.98 in.*lbf).
