AMA3 - Reworking Various Threaded Connections on the Chassis (Recall Campaign)
Revision:
This bulletin replaces bulletin Group 4 49/21 AMA3, dated March 31, 2021.
Model Year:
As of 2020 up to 2021
Model Line:
911 (992)
718 (982)
Concerns:
Hexagon clamping nut M12 x 1.5 on various threaded connections on the chassis
Information:
There is a possibility that clamping nuts, on which the thread was not manufactured
according to specifications, were installed on various threaded connections on the chassis
on the affected vehicles.
As a result, the required tightening torque was reached before the threaded connection was actually
tightened fully when installing the clamping nuts. There is therefore no guarantee that the affected
threaded connections will remain sufficiently tight over the service life of the vehicle.
Action required: Rework threaded connections on the front and rear axle.
On vehicles that have already been delivered to customers, the screwed components must also be
checked for damage.
Information
Please note that different screw positions on the front and rear axle must be reworked on the affected
vehicles.
The following specific campaign scopes have therefore been defined for reworking the threaded
connections. Every vehicle is clearly assigned just one campaign scope.
The relevant M12 x 1.5 fastening nuts must be replaced on all affected vehicles, depending on the
assigned scope.
In addition, the relevant fastening screws must also be replaced.
On vehicles on which a component is screwed at the relevant screw point (e.g. actuator or
connecting link), depending on the assigned scope, the thread on the relevant component must be
checked and the component may also have to be replaced, depending on the result of the check.
On vehicles that have already been delivered to customers, the components that are screwed
together must also be checked for damage caused by relative movements while driving as
installings, contact surfaces or bores on the individual components may have been damaged.
The relevant components may also have to be replaced, depending on the result of the check.
