Rules For Cleanliness When Working on Transmission

Rules for cleanliness when working on transmission, 02E, 6 SPD. DSG A/T
^ Do not run engine or tow vehicle with oil pan removed or without gear oil.
^ Carefully clean all joints and adjacent areas before disconnecting.
^ When installing transmission make sure that the dowel sleeves between engine and transmission are seated correctly.
^ Place parts that have been removed on a clean surface and cover so that they are not soiled. Use sheeting and paper. Do not use fluffy cloths!
^ Only install clean components: Unpack replacement parts immediately prior to installation.
^ Carefully cover opened components or seal if repairs cannot be carried out immediately.

O-rings, oil seals, gaskets
^ Always replace O-rings, oil seals and gaskets.
^ After removing seals/gaskets, examine the contact surfaces on housings or shafts for burrs and signs of damage and repair before reinstalling.





^ Before installing a radial shaft seal lubricate the outside diameter with gear oil and fill the space between the sealing lips (arrow) halfway with G 052 128 A1.
^ The open side of an oil seal faces the oil.
^ Always use transmission oil. Other lubricants will cause the hydraulics to malfunction.
^ Check gear oil level after installing and if necessary top off.

Nuts, bolts
^ Loosen and tighten nuts, bolts/screws for securing covers and housings in a diagonal sequence.
^ Do not tilt the very sensitive parts and also loosen and tighten in a diagonal sequence.
^ The torque settings indicated refer to non-lubricated screws and bolts:
^ Threads of bolts/screws that are secured by locking fluid are to be cleaned with a wire brush. Then insert bolts/screws with AMV 185 100 A1.
^ All threaded holes where locking fluid is applied must be cleaned with a thread tap to remove remnants of locking fluid.
^ Otherwise there is a danger that a bolt/screw will shear when reinstalling.
^ Replace self-locking nuts.
