Removing and installing wheel





Information

Wheel mounting

The wheels of the Boxster (987) are secured with standard wheel bolts (M14 x 1.5) the same as for the Boxster (986). Length: dimension -X- - screw length: approx. 45 mm.

Installing wheel

Information
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, re-grease the centering surface of the wheel hub (if required) as necessary with a very thin coat of Optimoly TA (aluminium paste).
The wheel bolt consists of two parts that are permanently joined together. Other wheel bolts must not be used.

Information
The assembly pins for removing/mounting the wheel for vehicles with PCCB can be ordered separately as a spare part. Part No.: 999 571074 30.

Caution
Removing/fitting the wheels for vehicles with PCCB (Porsche Ceramic Composite Brake).
Risk 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) into the wheel hub before mounting wheel.

2. In the case of heavy soiling, clean the wheel bolts and the concavities in the wheel with a lint-free cloth.
3. 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-. Do not grease the spherical cap bearing surface -X- of the wheel bolts that face the wheel.

-A- - Spherical cap ring (permanently connected with the wheel bolt)
-X- - Spherical cap bearing surface facing the wheel (do not grease)

Information
Rework on wheel bolts is impermissible.

4. 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.

Information
Always observe the specified tightening torque of 130 Nm (96 ftlb.).

5. Screw in wheel bolts by hand and then tighten evenly. Start at the top when tightening.
