51 71 115 Removing And Installing / Replacing Seal On Front Door, Left Or Right







Necessary preliminary work:
- Follow repair instructions for bonded gaskets.
- Remove cover on inside door window frame
- Release door stop from door pillar

NOTE:
- Positioning of the seal must be established in two areas of the front door with positioning aids to be stuck on.
- Positioning aids are included with new seals.

Position of seal (1) on front door:







Area (A) at distance (F) to door fold.
Area (B) at distance (G) to door fold.
Clean bonding surfaces on paint with adhesive remover (sourcing reference: BMW Parts Service).
F = 3.5 mm
G = 4.8 mm

Position of seal (3) on front door:







Align area (C) at line (1) of positioning aids (2) to be stuck on (observe following work steps).
Area (D) at distance (H) to inner door panel.
Area (E) at distance (I) to door fold.
Clean bonding surfaces on paint with adhesive remover (sourcing reference: BMW Parts Service).
H = 60.2 mm
I = 4.9 mm

Detach prestamped positioning aid from backing.
- Positioning aid "A1" front door, left (door lock, top)
- Positioning aid "B1" front door, right (door lock, top)

If necessary, cut out prestamped cut-out for bore hole from positioning aid. Align positioning aid with printed marks (X and Y) and contact edge (2) to front door and press.

Positioning aid "A2" for front door, left ("B2" right)







Detach prestamped positioning aid from backing.
- Positioning aid "A2" front door, left (door lock, bottom)
- Positioning aid "B2" rear door, right (door lock, bottom)

Seal must rest on positioning aid (1) during bonding.
X Start of bending radius
Y Recess for door lock







IMPORTANT:
- Do not grip bonding surface.
- It is not the time of the pressure, but rather the level of pressure (approx. 10 ... 15 N/cm2) that is decisive.
- Separation of seal after pressing destroys the adhesive layer.

NOTE: After being pressed on gently, seal can be pulled off again up to 3 times. Do not dirty bonding surface.

Stick on seal (1) as follows:
- Position seal with colour coding on door window frame at front top.
- Gently press seal without stretching up to start of positioning aids.
- Check positioning of seal, correct if necessary (sag max. 30 mm).
- Firmly press down seal vertically to bonding surface up to above-mentioned area.
- Gently press seal without stretching up to entrance area.
- Check positioning of seal, correct if necessary and firmly press.
- Pull remaining protective film (liner) off seal.
