🔌 Function

Locks its fastener against vibration and repeated torque reversal in the flywheel-housing and transmission-adapter joint, its prevailing-torque feature holding the nut in place even when the joint relaxes slightly in service.

⚠️ Common Signs of Failure

  • Rattle or knock from the flywheel housing area under changing load
  • Nut backing off after a previously correct tightening
  • Nut spinning on freely by hand, showing the locking feature is spent
  • Distorted or flattened locking section visible when the nut is off
  • Fretting and bright metal on the joint faces where the connection has been moving

🛠️ Service Notes

  • Confirm thread, length, grade and any single-use restriction against the exact application
  • Clean the threads and use the specified torque, angle and locking method
