Mounting wheel on vehicle
The wheels of the Cayenne are secured with -standard wheel bolts M14 x 1.5 x 51-.
^
Do not confuse the Cayenne wheel bolts with the sports car wheel screws (911 and Boxster)!
^
The wheel bolt for the Cayenne has a length of 51 mm, the disc (calotte) consists of steel and has a groove on it (911 and Boxster without groove
and disc consisting of aluminum. Standard length = 45 mm and GT3 = 50 mm).
On each wheel there is a -security wheel bolt (theft protection)-, which can be released or tightened with the master set T10190 in which all variants of
the wheel security system are present.
Mounting wheel on vehicle/Removing wheel from vehicle
Note!
^
Use suitable commercially available tools (wrench size 19 mm)! Never use an impact bolter to tighten the wheel bolts!
^
Use -assembly aids (threaded pin for mounting wheel)- in order to exclude any possibility of heavy contact of the wheel with the brake disc! The
assembly aids (threaded pins for mounting wheel) should be obtained via the Porsche parts service (Part No. 999.571.074.30)!
^
For vehicles with a Tyre Pressure Monitoring System (TPMS), every lyre set or wheel change must be communicated to the control unit. To do
this, always enter in the instrument cluster menu item "TPMS settings" the lyre type and lyre size. During driving the control unit then stores these
values.
^
The wheel bolt consists of two parts that are permanently joined together! Other wheel bolts must not be used!
^
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 axial direction.
^
The wheel bolts and security wheel bolts should not be greased!
^
Only original Cayenne wheel bolts should be used!
^
Always observe the specified tightening torque of 160 Nm (118 ft. lbs.)!
1. Screw the -assembly aids (threaded pins for mounting wheel)-, instead of 2 wheel bolts, into the wheel hub before mounting or removing wheel.
During removal, first remove the 3 remaining wheel bolts and remove the wheel carefully, without touching the brake discs.
2. Secure wheels using standard Cayenne wheel bolts M14 x 1.5 x 5 1.
