- Torque:
- 370 N*m{3773 kgf*cm, 273 ft.*lbf}or less
15. INSPECT DIFFERENTIAL DRIVE PINION PRELOAD |
Using a torque wrench, measure the preload.
- Standard Preload (Starting Torque):
Item
| Specified Condition
|
New bearing
| 1.1 to 1.6 N*m (12 to 16 kgf*cm, 10 to 14 in.*lbf)
|
Reused bearing
| 0.6 to 0.8 N*m (7 to 8 kgf*cm, 6 to 7 in.*lbf)
|
- If the result is not as specified, adjust the preload.
16. INSPECT TOTAL PRELOAD |
Using a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.
- Standard Total Preload:
Bearing
| Specified Condition
|
New
| 0.4 to 0.5 N*m (4 to 6 kgf*cm, 4 to 5 in.*lbf) + drive pinion preload
|
Reused
| 0.4 to 0.5 N*m (4 to 6 kgf*cm, 4 to 5 in.*lbf) + drive pinion preload
|
If the result is not as specified, adjust the preload.
17. STAKE DRIVE PINION NUT |
Using a chisel and hammer, stake the nut.
18. INSTALL REAR PROPELLER SHAFT ASSEMBLY |
