Bonding Sensor Bracket In Bumper Cover

Bonding Sensor Bracket In Bumper Cover

Special tools, testers and auxiliary items required

• Centering Drift (VAS6614/3)

Bonding of sensor bracket into front and rear bumper cover is performed in the same way. To assist in aligning the sensor retainers in their proper positions when bonding, sensor location punched holes with corresponding retainer bonding adhesive surfaces are marked on the inside of the bumper cover. Before proceeding with bonding procedure, ensure sensor retainer and bumper cover materials are between 15 °C (59 °F) and 25 °C (77 °F).

Procedure

- Remove any remaining adhesive still on the inside of the bumper cover.

- Clean the marked adhesive surface - 1 - on the inside of the bumper thoroughly with isopropyl alcohol.






- Apply the bonding agent "Scotchmount 4298" evenly in the marked adhesion surface - 1 -.

- Let the adhesive air dry for approximately 5 minutes.

- Allocate the sensor brackets to be bonded to their proper installation location.

- Remove both protection foils from sensor retainer bonding area - 2 - so that a gray surface becomes visible.

- Align the sensor bracket - 2 - with respect to marked adhesive surface - 1 - so that there is a uniform edge of approximately 3 mm. Use centering drift (VAS6614/3) for aligning with the punched hole.

Make sure that recesses for sensor connection in the sensor bracket face in the correct direction as depicted in the assignment. If sensor bracket is glued in incorrectly, connection wires for sensor are too short.

- Press the sensor bracket - 2 - with significant pressure into the bumper cover for approximately 10 seconds.

The contact pressure and pressing time are crucial for the adhesive durability!
