Wiring Eyelets, Repairing
Special tools and workshop equipment required
- Torque Wrench 1331 5-50Nm: VAG1331
Do not use rust remover, contact spray or grease because the lack of friction will cause the torque to be exceeded when installing and this will lead to the threaded connection breaking.
The gray sanding pads are for slight contamination and suitable for "soft surfaces". The red sanding pads are for heavy contamination and suitable for "hard surfaces".
Risk of injury! Pay attention to all warnings and safety precautions. Refer to WARNINGS AND SAFETY PRECAUTIONS .

Make sure that the tin layer is not worn down too much and that the copper is visible. A galvanic element can form from this, destroying the metal and causing incorrect repairs.
Due to the different thicknesses of the tin layer, the cleaning process must be performed in several steps and a visual inspection of the wiring eyelet between steps is necessary.
-- Insert the adapter in the wiring eyelet and grind off the corrosion and contamination with circular motions.
-- Check the wiring eyelet and grind down.
-- Remove the burr on the wiring eyelet with the deburrer.
-- Install the wiring eyelet to the specified tightening specification. Refer to COMPONENT LOCATION OVERVIEW - RELAY PANELS, FUSE PANELS AND E-BOXES or OVERVIEW - BATTERY .
