Removing/installing the wheel on vehicle - Turbo and GT2
NOTE:
- Use suitable commercially available tools (wrench size 19 mm)! Never use an impact bolter to tighten the wheel bolts!
- Before the wheel is placed on the wheel hub, regress the centering surface of the wheel hub (if required) as necessary with a very thin coat of Optimoly TA (aluminum paste)!
- The wheel bolt consists of two parts that are permanently joined together! Other wheel bolts must not be used!
CAUTION:
Vehicles with PCCB (Porsche Ceramic Composite Brake): Danger of material damage during wheel removal/installation (danger of damage to brake discs)!
- Use assembly aids (assembly pins) in order to exclude any possibility of heavy contact of the wheel with the brake disc! The assembly aids (2 assembly pins) are located in the luggage compartment!
- In the case of vehicles with PCCB (Porsche Ceramic Composite Brake), screw the 2 assembly aids (assembly pins), instead of 2 wheel bolts, into the wheel hub before wheel removal/installation. During removal, first remove the 3 remaining wheel bolts and remove the wheel carefully, without touching the brake discs.
NOTE: The assembly pins can be ordered separately as a spare part! Part No.: 999 571 074 30.
- Fasten the wheels with series wheel bolts (Turbo and GT2) -A- M14 x 1.5 (length 45 mm) dimension -X- . See Fig 2. See Fig 2.
- In the case of heavy soiling, clean the wheel bolts and the concavities in the wheel with a lint-free cloth.
- Always apply a thin coat of Optimoly TA (aluminium paste) on the thread of the wheel bolts, on the shank and between the bolt head bearing surface and spherical cap ring (under the head) -arrows-
. See Fig 2. Do not grease the spherical cap bearing surface -X-
of the wheel bolts that faces the wheel. See Fig 2.
NOTE: Rework on wheel bolts is impermissible!
- Always replace damaged wheel bolts.
This damage includes mechanical damage to the thread, the spherical cap and damage resulting from seizure of the bolt head bearing surface and spherical cap ring. It must be possible to rotate the spherical cap ring on the bolt shank and to move it in the axial direction.
NOTE: Always observe the specified tightening torque of 130 Nm (96 ft.lb). - Screw in wheel bolts by hand and then tighten evenly. Start at the top when tightening.
