If a wheel needs to be changed, the procedure described below must be adhered to exactly, as otherwise the wheel may loosen, resulting in damage. Porsche cannot be held liable if this happens.To achieve the high tightening torque required for the central bolt, a suitable, commercially available 443 ftlb. (600 Nm) torque wrench must be used. Alternatively, a corresponding tool with torque multiplier (part no. 997.450.323.90) is available from Porsche Motorsport. When a torque multiplier is used, the torque must be reduced in accordance with the tool’s operating instructions.
When loosening and fastening the wheel, a second person is needed to prevent the wheel from turning by firmly braking it.
The high mounting forces involved can cause the vehicle to roll away and slip off the jack.fAlways use a lifting platform if there is one available.
Risk of damage due to vehicle tipping over or falling off lifting equipment or using the wrong tool.
The high mounting forces involved can cause the vehicle to roll away and slip off the jack. An impact wrench can damage the central lock.fAlways use a lifting platform if there is one available.fDo not use an impact wrench .
