Version 1
Design group 28.10 Complete transfer case
Date 05-25-2011
Validity Veh. with transmission model 722.96x
Reason for change
Complaint:
Oil leakage at the seam between the automatic transmission and the transfer case housing.
Attachments
Leakage can occur all around the entire seam.
Cause:
Leakage due to the sealant applied during production.
Remedy:
Sealing with black sealant (Loctite 5970) only if there is definite droplet formation in the vicinity of the seam or in the vicinity of the propeller shaft to the front axle transmission.
If the problem is a "sweating" leak, sealing must not be carried out, as this is a normal phenomenon inherent in the design of oil-filled systems.
In accordance with the WIS instructions in the attachment, disassemble the transfer case housing and seal it using black sealant A003 989 98 20 10 (Loctite 5970).
The documents are also valid for model series 212 as this model series is fitted with the same automatic transmission and transfer case. A corresponding WIS document for model series 212 is currently being prepared.
