Thread cutters

Due to recent events, we again point out the importance of properly handling self-locking threaded connections.

In order to avoid consequential damage, self-locking screws/bolts (with microencapsulation) must ALWAYS be replaced. As described in the repair instructions, it is mandatory that the nut threads on the axle mount be recut and blown out with compressed air.

This is absolutely essential because adhesive residues in the thread make it impossible to achieve the required bolt prestress level, even if the specified tightening torque or angle is applied.

Failure to follow these instructions will result in insufficient prestress and the bolt will experience bending stress that could lead to breakage and great consequential damage.
