FAQ 

Q：What signs mean the clamp needs replacement?
A：Clamping force obviously weakened, stainless steel belt crack, serious surface rust, worm screw slipping and unable to tighten, permanent deformation of the band.

Q：What should be noted during clamp installation?
A：Clean hose and joint surface before installation; place the clamp at the middle position of the hose sleeve; tighten the worm screw with proper torque, do not over-tighten to prevent rubber hose damage.

Q：What are common causes of clamp damage?
A：Long-term vibration fatigue; excessive tightening torque; surface rust corrosion; high temperature aging; sharp objects scratch the steel band.

Q：Can deformed clamp be repaired and reused?
A：Not recommended. Once the steel band has permanent deformation or cracks, the clamping uniformity cannot be restored. Replace new clamp to guarantee intake sealing.

Q：How to inspect clamp during daily maintenance?
A：Check clamp tightness, steel belt rust and air leakage at joint before heavy-load operation. Focus inspection on worm gear and belt bending section, these positions are prone to fatigue failure.

Q：What failures will a failed clamp cause?
A：Failed clamp loses clamping force, air filter hose joint will loosen and leak air. Dust will enter the engine cylinder, accelerate cylinder wear, resulting in engine power reduction and increased fuel consumption.
