Checking measurement  
Note:  
For transmissions without polygon bearing, use VW521/8 bushing instead 
of VW521/12 shown. 
Notes:  -  After installing shims "S1" and "S2," turn differential 5 rotations in each 
direction to seat tapered roller bearings. 
-  Measure backlash 4 times on circumference.
   Specification: 0.12-0.22 mm
If backlash lies outside tolerance, repeat adjustments. Do not change 
total shim thickness "Stotal." The individual measurements must not vary more than 0.06 mm from 
each other.
