Repairing threaded connections

Special tools and workshop equipment required
♦ Torque wrench -V.A.G 1331-

Note

The use of penetrating fluid, contact spray or grease is pro‐

hibited since the lack of adhesion in the threads may cause a

torque excess and, therefore, the breaking of the threaded

connection.

The grey sanding pads are suitable for light dirt and "soft sur‐

faces". The red sanding pads are suitable for heavy dirt and

"hard surfaces".

– Select suitable adapter and suitable sanding pad for threaded

connection.

Caution

Take care not to abrade excessively the tin coating and ensure

that the copper does not appear. This could produce a galvanic

cell which destroys metal and causes faulty repair.

Note

As the thickness of the tin coating may differ according to the de‐

sign, the cleaning process must be performed step by step and a

visual check of the ring terminal is necessary between the steps.

– Set adapter on threaded connection and grind off corrosion

and dirt with circular movements.

– Check threaded connection and regrind it if necessary.
– Tighten connection and locating element again to specified

torque ⇒  Electrical system; Rep. Gr.  27 .

Note

Optimum contact is ensured when the components to be secured

are tightened to the specified torque after cleaning.

– Apply suitable anti-corrosion treatment to threaded connection

– Clean battery clamp using wire brush of battery terminal clean‐

er with circular movements.

– Clean battery terminal using underside of battery terminal

cleaner with circular movements.

Caution

Missing anti-corrosion treatment results in damage to the on‐

board supply.

3. Contact surface cleaning set VAS 6410     

115

All threaded connections must be tightened to specified tor‐

que.

Always use hose supplied with anticorrosive agent tin.

Use protection wax for cold area.

Use cavity sealing agent for warm area.

The sealing agent independently reaches the respective

points through capillary action.

Carry out following procedures:
– Hold injector below ring terminal and spray pin all around.

– Hold injector above ring terminal and spray pin and wiring eye

all around.
