Check angular alignment of axles

1

Regulate bearing brackets (2) feeler rods (1) at the same length and height



2

Position the bearing brackets (2) feeler rods (1) on flat surfaces on both sides of front rims, so that they are below the wheel central point

Check angular alignment of axles

3

Position the projectors (5) on the projectors support (4) of the 1st rear shaft



4

Direct the left projector (5) light beam onto the left measurement bearing bracket (2) scale and read the value
Example: 150 mm.


01 division on the scale corresponds to 10 mm



5

Direct the right projector (5) light beam onto the right measurement bearing bracket (2) scale and read the value
Example: 130 mm.



6

Establish the individual convergence value
. 
. 


The individual convergence value is half the difference between the two measured values
Example:Value indicated on the left scale: 150 mm
Value indicated in the right scale: 130 mm
Difference between the two values: 20 mm
Individual convergence value (D) : 10 mm



7

With the individual convergence value (D) and the respective vehicle wheelbase (R), determine in the table, the rear shaft (S) tilting (in angle minutes). Divide the individual convergence value (D, in mm) by the vehicle wheelbase (R, in mm)
Example: Individual convergence value (D): 10 mm
Wheelbase (R): 4000 mm
Factor (F/R) = 10 / 4000 = 0.0025 mm



8

With the factor (F/R) based on the table, determine the rear shaft (S) tilting
Example: Coefficient (D/R): 0.0025 mm
Rear shaft tilting (S): 8.6'



9

Record the measured value on the alignment form


The front shaft tilting should be determined only through a mechanical measurement or through the wheelbase, in case it is ensured that the rear shaft tilting is inside the established values.


Vehicles with two rear shafts:

Carry out the measurement on the 2nd rear shaft similarly to the procedure for the 1st shaft
