+ Re-install the retaining ring for the inner ring of the intermediate shaft.
+ Thoroughly clean the sealing surfaces of the gearbox sections with cleaning solution (part number: D 291 091
Al).
© NOTICE
The cleaning solution (part number: D 291 091 A‘) activates the surfaces before the sealant is applied and
must be used to ensure the sealant creates a functional sealing bond.
+ Allow flash-off time of 10 minutes for the sealing surfaces.
+ Apply silicone sealant (part number: D 176 501 A1) all around the sealing surface of the intermediate housing
(refer to Figure 17).
