51 32 154 Adjusting Left or Right Front Side Window
51 32 154 Adjusting Left Or Right Front Side Window
Special tools required:
Prerequisite:
- Vehicle must be standing on its wheels on a level floor
- Front door correctly adjusted to fit
- If necessary close soft top
IMPORTANT: When closing, the door window glass must not jam on the trim strip in any area of the window (window glass breakage).
If necessary, incoming check:
Prior to any adjusting procedure perform incoming check:
NOTE:
Incoming check must be carried out with the weather strip fitted.
- Denormalize power windows
- Measure retraction depths with special tool 51 3 080
- 51 0 341 Insert special tool in rotary striker and close rotary striker
- 51 0 342 Measure preload with special tool
- Initialize power window regulators
Necessary preliminary tasks:
- Denormalize power window
- Remove outer weather strip (not for checking pretension)
Ideal adjustment, longitudinal direction:
Open door window.
Insert special tool 51 0 330 in front door.
Raise the door window.
51 0 330Door window glass must rest without play on special tool.
Ideal adjustment, retraction depth:
- Open side window
- Attach special tool 51 3 080 to door window glass
- Close front door and door window
- Measure retraction depth
NOTE: In order to adjust the retraction depth, 2 special tool 51 3 080 are required.
Measure retraction depth (C) in areas (A and B).
Retraction depth (C):
A = 4.0 ± 0.5 mm
Distance between measuring point and mirror triangle = 30 mm
B = 6.0 ± 0.5 mm
Gap between measuring point and window edge = 30 mm
IMPORTANT: Front door must open and close without the side window touching the roof trim strip.
Adjusting longitudinal direction/retraction depth:
Slacken hook screws (1) 51 3 240 with special tool until door window glass can just be moved.
Attach special tool 51 3 010 to door window glass (1).
Slide door window glass (1) 51 0 330 up against limit position of special tool.
Adjust retraction depth of door window (1) in area of A-pillar and B-pillar.
NOTE: When adjusting retraction depth, ensure door window glass (1) is supported by special tool 51 0 330.
Installation note:
The specified tightening torque 51 32 1AZ (MDE) is reduced when using special tool 51 3 240. Depending on the torque wrench used, this must be calculated in accordance with the adjacent overview:
MDE = Torque to be set
MDV = Prescribed torque (without special tool)
lj = Standard adjustment length with adjusting tool
l1 = Effective length of torque wrench
l2 = Inside dimension of adjusting tool
lw = Inside dimension of insertion tool (here lw = 246 mm+l2)
Installation note:
If screwing is performed from the inside of the door (removed door trim panel), the tightening torque to be set 51 32 1AZ (without special tool) must be observed.
Tighten hook screw (1) 51 3 240with special tool.
Check adjustment, repeat procedure if necessary.
Ideal setting, preload:
NOTE: Pre-tension can be checked with or without weatherstrip. Pre-tension is 1.0 mm less with weather strip. Magnet in special tool 51 0 341 creates the correct door window glass pre-tension on the seal system for measurement. No force must be exerted on the door or door window glass during measurement.
Insert special tool 51 0 341 in rotary striker of door lock and close rotary striker manually. Carefully close door.
Slide special tool 51 0 342 at distance (B) to door window glass side edge into seal (1) and measure dimension (A) to outside edge of door window glass (2).
Dimension (A) with weatherstrip:
A = 46 ±1 mm
Dimension (A) without weather strip:
A = 47 ±1 mm
B = 10 mm
Adjusting pretension:
Slacken nut (3) with reversible ratchet (2) of special tool 51 3 300 (consisting of 51 3 301, 51 3 303 and 51 3 304).
Turn knob (1) on special tool 51 3 300 to turn bolt (4) and thereby alter the pretension.
Tighten nut (3).
Tightening torque 51 33 1AZ.
Check adjustment, repeat procedure if necessary.
NOTE:
After completing adjustment work, it is essential to initialize the power windows unit.
Checking run-in of door window glass:
Door window glass must strike the inside of the gasket.
Check adjustment of rear side window, adjusting if necessary.
