Thread repair kit
The chassis and the assembly carriers are bolted to the aluminum cast parts of the
body. To meet these special requirements, the threads are provided with Helicoil
threads. A repair kit is available for replacing these Helicoil threads. When opening a
bolted connection, it is absolutely necessary to replace the bolt. This also applies to
the assembly mounts. If the thread is damaged, replace the thread insert and fit a
new Time-Sert thread insert.
Defective Helicoil threads of the bolted connections of
chassis and assembly carrier have to be replaced by
Time-Sert thread inserts. It is not allowed to replace a
defective Helicoil thread by a new Helicoil.
Two systems are available for thread repair. The Helicoil repair system supplied by
Böllhoff and Time-Sert thread inserts supplied by Würth. Porsche recommends
special thread repair kits for particular thread sizes.
It is important that the corresponding tightening torque of the bolted connection can
be achieved after repair.
