Replacing Output Flange (A5S 325Z)

WARNING: This page does not describe the selected car, but rather 49 other vehicles, including the 2007 BMW Z4, 2007 BMW X3, 2006 BMW Z4, 2006 BMW X5, and 2006 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Numbers in text refer to numbers in figures.

Remove output flange from mounting. See REPLACING RADIAL SEAL FOR OUTPUT FLANGE (A5S 325Z) . Installation: coat sealing lip of radial seal and sealing surface of output flange with ATF.

Installation: an end float of 0.15 - 0.35 mm is required between parking interlock gear and end face of output flange. End play is adjusted with shim (1). See Figure . Replace sealing ring.

NOTE: Output flange must be free.

Determining thickness of shim: clamp transmission extension in a vise. Press output flange in direction of arrow. See Fig 1 .

Determine distance (A) from shoulder to sealing surface and distance (B) from shoulder to end face of output flange. See Fig 2 . Example:

A = 10.00 mm
B = 7.50 mm

Remove shim from sprag wheel. Press sprag wheel inwards. Determine distance (E) from sealing surface on transmission housing to shoulder (1) on parking lock gear. See Fig 3 . Example: E = 4.00 mm.

NOTE: Shims are available in 0.2 mm increments from 0.8 to 2.8 mm.

Calculate shim thickness:

A - B = C
E - C - end play = shim thickness
If necessary: round distance to an amount divisible by 2. Pay attention to distance for end play (0.15 - 0.35 mm) in so doing. Example:
- 10 - 7.5 = 2.5
- 4 - 2.5 - 0.25 = 1.15 3. 1.2

Install shim (example: 1.20 mm).
