Notes on gearbox adjustment
Adjustment work is divided into 2
»sections«
:
A
This involves finding shims that are inserted into clutch housing.
This is the start of the work. Objective is to align output shafts 1 to 3 in clutch housing
»in one imaginary plane«
. This
»imaginary plane«
is defined by face end of outer input shaft. For this procedure, refer to chapter
Chapter
.
On gearboxes as of production date 06/2011 a constant plate is inserted underneath the bearing race of the differential. The constant plate is not shown in the illustration. If fitted, it must be installed together with the bearing race.
B
During assembly of gearbox,
»thickness«
of these shims determines force with which shafts are
»clamped«
between both halves. These shims are inserted in gearbox housing.
For this procedure, refer to
Chapter
Only once correct shims
A
have been calculated for clutch housing, or if there is no need for measurement, can shims
B
be determined.
Therefore, do not calculate shims
B
until shims
A
are OK.
Work with intact tools, make sure the workplace is clean.
Avoid temperature differences between gearbox and adjusting tool.
Flange surfaces of both housing halves should be smooth and neither
»indented nor damaged«
.
Do not put on measuring table unless there are guide bushes in housing.
Do not swap over bearing races of same size, always renew bearings on a shaft jointly.
Follow this procedure step by step. Temperature differences, such as between
»summer and winter«
, affect all measuring tools that are used.
Numbers given in the calculations below are in millimetres.
»Your measuring tools«
and
»dimensions on your gearbox«
will differ from the values stated here. Numerical values such as these are always identified with this supplement:
example
.
Notes made during measurements should be legible and easy to follow. Oily pieces of paper are not appropriate for this.
