939010869 - 4450A40 REAR WHEEL GEOMETRY - CHECK USING OPTICAL EQUIPMENT, INCLUDES ADJUSTMENT IF NECESSARY
GEOMETRY CHECK- Check the rear wheel geometry, ensuring that ground clearance D - C is within the following values.| Rear wheel geometry (standard 0) |
|---|
| Distance D - C | 23 ± 5 | mm |
| Rear wheel geometry (standard A) |
|---|
| Distance D - C | 12 ± 5 | mm |
TOE IN CHECK- Check that the rear wheel half toe-in is within required limits.| REAR WHEEL SEMI TOE IN |
|---|
| Standard 0 | 11’ ± 7’ | - |
| REAR WHEEL SEMI TOE IN |
|---|
| Standard A | 13’ ± 7’ | - |
- If the rear wheel half toe-in is not within the recommended figures, adjust it following the instructions given below.CAMBER CHECK1. Check that the rear wheel camber is within required limits.| REAR WHEEL CAMBER |
|---|
| Standard 0 | -25’ ± 18’ | - |
| REAR WHEEL CAMBER |
|---|
| Standard A | -40’ ± 18’ | - |
- If the rear wheel camber is not withinspecified limits, adjust as follows.
ADJUSTING THE CAMBER AND TOE-IN1. Undo the bolts securing the rear suspension longitudinal arms to the stub axles and adjust the screws to alter the rear wheel toe-in.- Screw in the bolts securing the rear suspension longitudinal arms to the stub axles without tightening them.
1. Adjust the screws for the bolts securing the track control arms (camber rod) to adjust the camber of the rear wheels to the recommended value.- Tighten the wishbone bolts (camber rod) to the specified torque.| Component | Fastening | dia | Value (daNm) | Validity |
|---|
| Steering knuckel side camber rod | Bolt | M12 | 7.8 ÷ 9.3 + 30° | |
1. Adjust the screws for the bolts securing the rear suspension longitudinal arms to the stub axles to adjust the toe in to the recommended value.- Tighten the bolts securing the rear suspension longitudinal arms to the steering knuckles to the specified torque.| Component | Fastening | dia | Value (daNm) | Validity |
|---|
| Steering knuckle side longitudinal arm (toe in) | Bolt | M14 | 9.5 ÷ 10.5 + 45° | |
