Common Faults & Troubleshooting
- Thread stripping or seizing: Caused by excessive installation force or thread damage. Replace 72632 double end stud and clean matched threaded holes.
- Breakage or loss: Resulting from vibration fatigue or overloading. Replace with a new stud and tighten to specified torque.
- Rust and seizure: Caused by long-term damp and oily environment. Disassemble with special tools and replace with a new stud.
- Loosening and leakage: Caused by insufficient tightening or gasket failure. Retighten studs and replace sealing gaskets.
