Determining thickness of shim"S2"  
     
Formula:  
"S2"  
=  
"S2*" - backlash + lift  
     
Example:  
  
   Inserted shim "S2*"   1.20 mm  
-   Average backlash   0.49 mm  
+   Lift (constant)   0.15 mm  
=   Thickness of shim "S2"   0.86 mm  
     
-  Determine shim(s) from table.

1) Using the shim tolerance variations it is 
possible to find the exact shim thickness 
required, insert two shims if necessary.

Determining thickness of shim "S1"  
     
Formula:  
"S1"  
=  
"S
total
" - "S2"  
     
Example:  
  
   Total shim thickness "S
total
" for "S1" 
+ "S2"  2.07 
mm  
-   Thickness of shim "S2"   0.86 
mm  
=   Thickness of shim "S1"   1.21 
mm  
     
-  Determine shim(s) from table.

Performing check measurement  
Note:  -  After installing shims "S1" and "S2," turn differential 5 turns in both 
directions so that the tapered roller bearings settle. 
-  Measure backlash four times on circumference.
   Specifications: 0.12-0.22 mm
If the backlash lies outside the tolerances, the adjustments must be 
repeated. But the total shim thickness "S
total
" must remain the same. 
The individual measurements must not differ by more than 0.06 mm 
from each other.
