Mounting Wheel on Vehicle/Removing Wheel From Vehicle
Mounting wheel on vehicle/Removing wheel from vehicleNote!
^ Use suitable commercially available tools (wrench size 19 mm)! Never use an impact bolter to tighten the wheel bolts.
^ Before putting the wheel on the wheel hub (to the extent necessary) apply a very thin coat of Optimoly TA (aluminum paste) to the centering surface on the wheel hub.
^ 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 when removing/fitting the wheels (danger of damage to the 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.
1. 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 for removing / mounting the wheel for vehicles with PCCB can be ordered separately as spare parts. Part No.: 999 571 074 30.
2. Fasten wheels in accordance with the assigned wheel bolts. Wheel bolts -A- M14 x 1.5 (length 45 mm) dimension -X- for Carrera and for GT3 - as of model year 2004. Wheel bolts -B- M14 x 1.5 (length 50 mm) dimension -X- for GT3 - up to model year 2003 (identification with GT or red color -arrow-).
3. In the case of heavy soiling, clean the wheel bolts and the concavities in the wheel with a lint-free cloth.
4. Always apply a thin coat of Optimoly TA (aluminum 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-. Do not grease the spherical cap bearing surface -X- of the wheel bolts that faces the wheel.
A Spherical cap ring (permanently connected with the wheel bolt)
X Spherical cap bearing surface facing the wheel (do not grease)
Note!
^ Rework on wheel bolts is impermissible.
5. 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 axial direction.
Note!
^ Always observe the specified tightening torque of 130 Nm (96 ft. lbs.).
6. Screw in wheel bolts by hand and then tighten evenly. Start at the top when tightening.
