Centre Lock Wheels
These wheels require specialist tools and should only be removed
by an Aston Martin technician.
Warning: The centre lock wheel nut and cone should be
inspected for damage whenever the wheel is removed. If
either component show signs of damage, the must not be
used. There is a risk that they will not be able to securely
hold the wheel on and may fail. Regardless of any visible
damage, both the wheel nut and cone must be replaced at
25,000 km (15,500 miles) or after they have been removed
and installed 5 times.
Warning: Wheels should be installed when cold. If the
wheels are installed while the wheel and hub are hot, then
the torque applied to the wheel can change as they cool
down.
Warning: If the vehicle is used for continuous fast driving
(such as on a track), check the wheel torque before returning
to normal road driving.
Warning: You must not drive the vehicle without the
security cap for the centre lock nut installed.
Caution: Before removing the wheel, make sure you have
a torque wrench able to torque the wheel nut to 1000 Nm
(740 ftlb) and a replacement thrust washer available. If you
do not, the wheel must not be removed as you will not be able
to safely install the wheel back onto the car.
Caution: Due to the high torque required to release the
centre lock nut, all wheels not being removed must be
secured to prevent the vehicle moving.
Caution: Do not let the wheel tilt or sit on the thread for
the centre lock hub. Doing so can damage the thread for the
wheel nut.
Keep the centre lock nut clean when removed from the wheel
hub. Replace any grease that has been lost to protect the thread
for the centre lock nut.
