| 1. |
Side bearing preload
|
| A thrust load is received from the ring gear, so if the preload adjustment is poor, the side bearing taper roller will wear causing noise and incorrect gear tooth contact, leading to tooth damage. To prevent this, preload adjustment using the adjusting shim or adjusting nut is required. |
| 2. |
Drive pinion preload (FR)
|
The ring gear generates a thrust load, which is received by the drive pinion. If the preload adjustment is poor, the taper roller bearings on both ends of the drive pinion will wear causing noise and incorrect tooth contact, leading to tooth damage
To prevent this, preload adjustment using the adjusting shim or collapsible spacer is required. |
| 3. |
Hypoid gear backlash (FR)
|
| The ring gear generates a thrust load, which is received by the drive pinion. If the backlash adjustment is poor, damage will occur to the teeth of both gears and excessive noise. Backlash adjustment is required using the adjusting nut or adjusting shim to set the backlash. |
| 4. |
Hypoid gear tooth contact (FR)
|
| The ring gear generates a thrust load, which is received by the drive pinion. If the tooth contact adjustment is poor, damage will occur to the teeth of both gears and seizing or noise. Even if pre-load and backlash are adjusted correctly, noise or tooth damage will result if tooth contact is not set correctly using the adjusting shims |
