Determining thickness of shim
Determining thickness of shim
The specified bearing preload is obtained by adding a constant figure (0.25 mm) to the reading indicated.
Example:
   
Measured value0.70 mm
+ Preload (constant value)0.25 mm
Thickness of shim =0.95 mm

–  Take off gearbox housing.
   
–  Pull tapered roller bearing outer race out of gearbox housing.
A - Counter-support, e.g. -Kukko 22/2-
B - Internal puller 46 ... 58 mm, e.g. -Kukko 21/7-
–  Determine part number of shim from → Electronic parts catalogue.
–  Install shims of the calculated thickness, thickest shim first.
The following shims are available:
  N39-1102
Shim thickness (mm)
0.650.851.051.25
0.700.901.10 
0.750.951.15 
0.801.001.20 

If the size of the shim required is larger than those listed in the table, install two shims amounting to the correct value. Insert the thicker shim first.
Tolerance variations make it possible to obtain the exact shim thickness required.
   
–  Press outer race in again and tighten gearbox housing to specified torque → Item and → Item.
