Calculation of shims required for upper bevel pinion shaft bearing
By means of the equation
X = D - H
the required thickness of the shim (Item 3 figure 108 or 109) can be calculated, i.e. with
Dimension "D"
Dimension "H"
Dimension "a"
Example :
Distance dimension : Dimension D measured on the housing
Bearing slack :
X = D - H - a
X = 0.7 - 0.10 - 0.04 = 0.56 mm
Add shims corresponding to thickness X = 0.56 mm.

INSTALLATION OF UPPER TAPER ROLLER BEARING OF THE BEVEL PINION SHAFT
Prepare the shim thickness determined according to chapter (5) above "Calculation of shims
required for upper bevel pinion shaft bearing" by means of the differently thick shims and continue
the installation as follows:
Put shim(s) (item 1) and bearing outer
ring (item 2) into the bearing seat.
By means of striking mandrel "S" install
the shim(s) and the bearing outer ring
into the bearing seat of the housing until
contact is obtained.
A repeated measurement of the
bearing height is only allowed to result
in a deviation of max. ¡ 0.05 mm.
Otherwise the process of the shim
calculation has to be repeated.
