51 31... Window glass removal with wire pull handle

WARNING:

Follow SAFETY INSTRUCTIONS for working on vehicles with airbag systems (risk of injury).

Always wear safety goggles and protective gloves for your own safety.

Attention! Handle sharp-edged tools with care (risk of damage to the head airbag and the window glass).

Attention! Follow the vehicle-specific repair instructions! Protect inner and outer working area (body, trim panels, cables etc.) against damage.

Depending on the area of application, a separating cord can also be used as an alternative to wire (Cutting cord, part number 81 43 2 344 272, refer to BMW Electronic Parts Catalogue).

Using the separating cord prevents any damage to the body.

Do not pull the separating cord over any sharp edges (risk of tearing)!

Use tools:

Wire pull handle with suction element, part number 81 43 2 326 501, refer to BMW Electronic Parts Catalogue
Dashboard protector for vehicle window removal, part number 83 30 2 337 983, refer to BMW Electronic Parts Catalogue
Wire starter for window glass disassembly, part number 83 30 2 336 541, refer to BMW Electronic Parts Catalogue

Use suction cups 51 3 010 to lift out the window glass.

Always keep both suction cups dry and clean to ensure their optimum adhesion on the windscreen.

Secure window glass (if necessary with adhesive tape) against falling out.
