To correct the articulation angle on the rear axle differential (50), suitable adjusting plates (2) are available as a replacement part set.
The replacement part set contains 6 adjusting plates (2) and therefore it has 6 different setting options each (3 adjusting plates (2) times 2 alignments) in 1 mm steps. A 1 mm change to the adjusting plate (2) causes a change in angle of 0.2°.
- Support rear axle differential (50) with support plate and major assembly mount.
- Remove bolts (3).
- Depending on the correction, insert appropriate adjusting plates (2) together with screws/bolts (3).
The adjusting plates (2) must be inserted accurately at the rear bearings of the rear axle differential (50).
Damage will otherwise occur.
- Tighten new bolts (3)
.
To do so, recut the thread in the cover for the rear axle differential (50).
- Take off support plate and major assembly mount.
Example for calculating ratio of angle change to adjusting plates (2)
The articulation angle between the propeller shaft and the rear axle differential (50) should be -0.7°. An adjusting plate (2) with 2 notches at the top (+1.5 mm) has already been inserted into the vehicle, but +0.1° is measured.
Required correction to articulation angle: (-0.7°) - (+0.1°) = 0.8° → 4 mm change towards smaller articulation angle required → insert new adjusting plates (2) with 3 notches at bottom.
Remove installed adjusting plates (2) with 2 notches at top (+1.5 mm) and replace with adjusting plates (2) with 3 notches at bottom (-2.5 mm). This is equivalent to the required total change of 4 mm.
- 1 notch at top: +0.5 mm (+0.1°)
- 2 notches at top: +1.5 mm (+0.3°)
- 3 notches at top: +2.5 mm (+0.5°)
- 1 notch at bottom: -0.5 mm (-0.1°)
- 2 notches at bottom: -1.5 mm (-0.3°)
- 3 notches at bottom: -2.5 mm (-0.5°)
