51 71 115 Replacing seal on left or right front door

Follow REPAIR INSTRUCTIONS for bonded seals.

Necessary preliminary work:

IMPORTANT:

After disengaging door stop, use suitable means of preventing door from opening past its maximum permissible opening angle (risk of damaging paintwork or bodywork)
Do not touch the bonding surface and make sure it is kept perfectly clean
Do not overstretch or compress the seal when positioning it
Maximum permissible sag of seal during positioning process 30 mm
Always apply pressure perpendicular to the bonding surface to affix the seal
It is the contact pressure applied (approx. 10... 15 N/cm² ) that is decisive for a good bond, not the length of time over which pressure is maintained.
Only after being pressed on gently , the seal can still be peeled off and repositioned up to 3 times
Disengaging the seal after it has been pressed on firmly destroys the adhesive bond.

Suspend seal (1) with open lip pointing inwards over door.

Remove protective film around colour coding (positioning aid).

Position seal (1) with colour coding at the top front on the window frame.

Glue seal as follows:

Follow the gluing sequence described below
Gradually peel off protective film and lightly press seal (1) into position on inner door panel
Check position of seal (1); correct if necessary until positioning is perfect
Apply firm pressure to seal (1).
