Using the contact surface cleaning set -

VAS 6410-

The contact surface cleaning set -VAS 6410- allows optimal repair

quality to be achieved in the area of vehicle electrics. The tools

allow performing repair work in the area of the sensor in wiring

harnesses for threaded connections in the high-current circuit

(starting and charging current). The easy-to-use contact surface

cleaning set -VAS 6410- has been designed to match the struc‐

tural design of the vehicles and ensures that repairs are carried

out correctly.

Note

The illustrations shown here are just a few examples of repair

work.

Repairing ring terminals

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".

nection.

– Check ring terminal for corrosion and dirt.
– Select suitable adapter and suitable sanding pad.

Note

As an alternative, the sanding block may also be used.

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.

– Insert adapter into ring terminal and grind off corrosion and dirt

with circular movements.

– Check ring terminal and regrind it.
