Attention! If the mechatronics breather is damaged during removal, it must be replaced. It is not possible to check the hydraulic oil level in the mechatronics circuit. Before installation, the vent hole of the Mechatron/R unit must be plugged to prevent oil leakage. The oil level in the mechatronics hydraulic circuit is not monitored and any oil spilled cannot be replenished. If oil leaks, the mechatronics must be replaced!
The gearbox with clutch must be installed on the gearbox bracket - T30109 (VW 353) - with an upward movement. After moving and securing the gearbox on the mounting stand, it must be inspected.

Hint: Pull the clutch up. The mechatronics remains in gear.
Remove the disc hub retaining ring "see arrow".

Remove the hub using hook "3438" and a screwdriver.

Remove the clutch retaining ring "see arrow".

Note: It happens that the clutch is so tightly pressed against the retaining ring that the retaining ring "sits very tightly". In this case, it is permissible to press the clutch down a little, as described in the following procedure. This relieves the retaining ring. Do not hit the clutch or shaft with a hammer! Always replace the retaining ring "see arrow".
The clutch retaining ring "arrow" cannot be removed.
Note: If the retaining ring cannot be removed, press the clutch down slightly as described below.
Install the support bridge "T10323" parallel to the clutch housing flange. Adjust the distances, for example, with washers "B" for a total thickness of 15 mm. Fasten the support bridge "T10323" with screws "A" and nuts.

Caution! Risk of damage to the clutch and other components! The clutch should only be pressed down slightly without applying much force.
Carefully press the clutch down on the spindle. Remove the support bridge "T10323". Remove the clutch retaining ring "see arrow".

Caution! The retaining ring must not be reused.
Continuing work after removing the clutch retaining ring
Install the "T10373" puller into the clutch and disconnect the clutch.

Remove the clutch together with the puller "T10373".

Remove the small engagement bearing.
Remove the large power lever.

Note: The upper part of the guide sleeve cannot be removed and installed separately. It can only be removed and installed together with the lower part of the guide sleeve and the small release bearing.
Adjusting the positions of the release bearings of the clutches "K1 and K2"
Attention. When replacing the dual clutch, the following parts must be replaced at the same time: both engagement levers with release bearings, the spherical journal of the clutch engagement lever, and the adjusting washers of the release bearings. After replacing the dual clutch and the above parts, it is necessary to readjust the position of the release bearings of the friction clutches "K1" and "K2". No adjustment is required if the above parts were simply removed and installed. The retaining ring must be replaced in each case.
Install only a perfect tool. The clutch housing flange must be "absolutely flat". This ensures a tight fit of the ruler. The mechatronics is installed.
Brief description
The position of the engagement bearing is related to the clearance between the bearing and the release levers of the manual transmission. In the DSG, tolerances are provided for the engagement system of the transmission and for the transmission itself. Tolerances also exist within the dual clutch. These tolerances must be taken into account separately when adjusting. The following procedure first shows how to determine all the necessary dimensions "on the transmission side" in order to install the appropriate adjusting shims. The tolerances on the transmission side and the tolerances in the clutch determine the thickness of the adjusting shim.
