Checking of bearing friction torque on
wheel shaft
Rolling
For measuring of the bearing friction
torque place tool "S" on the wheel shaft
congruent with the wheel bolts and by
means of the torque spanner turn the
wheel shaft several times.
(S) : Measuring fixture 62532
Bearing preload is adjusted correctly when a bearing friction torque of is obtained at the wheel
shaft.
If this value is not reached the working steps from Chapter 10) (2) have to be repeated. The cover
has to be removed again.
If the measured value is greater than the above mentioned value, the shim thickness of value "X"
in "Chapter 10) (2) calculation of shim required" has to be reduced.
If the measured value is smaller than the above mentioned, the shim thickness of value "X" in
"Chapter 10) (2) at page 3-43 calculation of shim required" has to be increased.

Measuring of torsional backlash on
wheel shaft
For measuring of the torsional backlash
lock the bevel pinion shaft against
distortion, e.g. with a wooden wedge
(item 1).
Measure the torsional backlash with
measuring stop "S".
(S) Measuring stop 62819
Admissible torsional backlash :
The torsional backlash can be adjusted
by adding or removing of the shim(s)
(see chapter 6) (2) at page 3-27
"determination of the necessary shim
thickness for optimum setting of the
torsional backlash of crown gear"). The
wheel shaft has to be removed again.
