The articulation angles can be calculated using the difference between the respective absolute angles.

Front articulation angle (1) :

Transmission to front propeller shaft

Center articulation angle (2):

Front propeller shaft to rear propeller shaft

Rear articulation angle (3):

Rear propeller shaft to rear axle center assembly



All articulation angle differences should be as close as possible to the center of the relevant tolerance range.

P41.10-2057-01

Correcting rear articulation angle (3):

In the example, the front and center articulation angles (1, 2) are within the tolerance range, but the rear articulation angle (3) is outside the tolerance range.

To correct the rear articulation angle (3), fit a shim of 2 mm thickness between the rear axle housing and rubber mount, in addition to any existing shims (arrow).

A 1 mm thick shim changes the articulation angle by approx. 0.25° to 0.33°.



Shims are available as replacements parts in thicknesses from 1 mm to 4 mm.

The bolt length does not have to be increased when using shims up to a maximum of 6 mm thickness.

If a shim thicker than 6 mm is required, check the front rubber mounts of the rear axle mount for correct position and signs of wear, and replace if necessary.

Shows model 203

Correcting front (1) and center articulation angles (2)

Shims in steel or aluminum will need to be fabricated on-site to correct the inclination angle. The dimension for the shims must be taken from the corresponding part.

Depending on the correction the shim must be installed between the:

 Rear engine crossmember and frame floor.

 Rear engine crossmember and rear engine mount.

 Driveshaft intermediate bearing and frame floor.

A 1 mm thick shim changes the articulation angle by
approx. 0.17°.



When using shims > 2 mm thick, increase the bolt length by
5 mm.

If you determine that the shim depth required to obtain the desired correction exceeds 5 mm, proceed to inspect the front and rear engine mounts for signs of wear and compression, replace as indicated.

Carry out a check measurement again each time the articulation angle is corrected.
