Note:  
Make sure gauge contact surface is precisely installed and free of oil.  -  Place end gauge on face of pinion shaft.
    
-  Remove master gauge and install measuring mandrel into transmission 
housing. 
Dial indicator extension -A- = 6.5 mm long must be installed. The VW385/3 centering disc faces cover for final drive 
-  Install differential cover and tighten 4 bolts to 22 Nm (16 ft lb).
-  Using adjustable ring, pull 2nd VW385/3 centering disc out as far as 
possible, so mandrel can only just be turned by hand.

Measuring friction torque  
     
Notes:  
     
Pinion shaft/hollow shaft tapered roller bearings 
are low friction bearings. Therefore the friction 
torque has only a limited use as a check. 
Correct adjustment is only possible by 
determining the total shim thickness Stotal. 
     Do not additionally oil new tapered roller 
bearings to perform the friction torque 
measurement. These bearings have already 
been treated with a special oil by the 
manufacturer. 
    
Friction torque specification:  -  Install torque gauge, 0-600 Ncm (53 in. lb) on pinion shaft.
-  Read off friction torque.

Used bearings
