FAQ 

Q：Can spider with minor crack be welded and reused?
A：Not recommended. Cyclic load leads to crack propagation and fan disintegration risk.

Q：Can old fan blades be reused with new spider?
A：Inspect blades for damage and redo dynamic balance, unbalance causes heavy vibration.

Q：Can stripped thread holes be repaired by tapping larger size?
A：Not recommended. Aluminum alloy has limited strength, hole may break under vibration.

Q：Does heavy fan vibration mean the spider is damaged?
A：Not necessarily. Check blade damage, unbalance and drive bearing first.
