51 31... Notes on window bonding: Installation
To prevent a pressure build-up in the passenger compartment when the doors are closed:
- Open a side window
After the adhesive bead has been applied, the window glass must be fitted within 5 to 10 minutes (depending on air humidity, temperature and use of accelerator).
After 5 to 10 minutes the adhesive bead forms a skin which can no longer guarantee a perfect bond.
1-hour system:
Once the adhesive bead has been applied, the window glass must be installed within 7 minutes (depending on air humidity, temperature).
After 7 minutes the adhesive bead forms a skin which can no longer guarantee a perfect bond.
The general rule is:
To secure the window glass, use only the yellow plastic adhesive tape (sourcing reference: BMW Parts Department, part number 83 19 9 410 979).
The window glass will slip down if other adhesive tapes are used.
Window glass slippage will result in leaks and wind noises.
Remove adhesive residue immediately with adhesive remover (Sika remover 208, sourcing reference: BMW Parts Department). Do not press out the window glass again.
Hardened adhesive can only be removed mechanically.
Check height of windscreen/rear window with special tool 51 0 010 or 51 3 210.
Assemble vehicle.
