7-speed dual clutch gearbox 0AM - Edition 07.2010
– To make sure this measurement is as accurate as possible,
position digital depth gauge twice at opposite sides.
This allows the value to be found even more accurately, because
the inaccuracy caused by "tilting" on the engagement bearing is
minimised.
– Calculate average of both measurements onto gauge block -
T10374- .
– Note down this value and call it "A1".
Example:
Dimension "A1" = 2,61+2,812 = 2.71
Example: "A1" = 2.71 millimetres
Next calculation:
"A1" minus "B" plus height of gauge block -T10374- = Depth of
engagement bearing of clutch 1.
Height of gauge block -T10374- is always the same. It is: 51.81
mm.
Sample calculation:
2.71 mm minus 2.96 mm plus 51.81 mm = 51.56 mm.
You have now calculated value for how deep engagement bear‐
ing is actually seated inside gearbox.
Depth of bearing in each gearbox should be 50.08 millimetres.
Subtract nominal dimension "50.08 millimetres" from this actual
value. This gives result for actual gap of clutch 1.
– Continue the calculation:
Calculated value (in example: 51.56 mm) minus nominal dimen‐
sion = gap of clutch.
Sample calculation:
51.56 mm minus "50.08 millimetres" = gap of clutch 1 = 1.48 mm.
Now tolerances in dual clutch must be introduced into this calcu‐
lation. Procedure for this is very simple:
– Please read off value of clutch tolerance of "new" clutch.
A value between minus 0.40 and plus 0.40 millimetres is provided
with a new clutch.
– Make a note of this value.
Example 1: "- 0.40" is indicated on your clutch.
The previous calculation for "K 1": "your calculated" gap minus
value of clutch 1 =
1.48 mm minus 0.40 = 1.08 mm.
Example 2: "+ 0.20" is indicated on your clutch.
Then, the last calculation of "K 1" is as follows: 1.48 mm plus 0.20
= 1.68 mm.
– Refer to table to find correct shim and install.
