FAQ

Q: Can a slightly worn pin stay in service?
A: Minor wear without ovality or bending is acceptable with frequent lubrication. Replace it once worn thin, oval or bent.

Q: What causes the pin to seize?
A: Insufficient lubrication, trapped asphalt debris or worn bushings. Clean, lubricate, and replace worn parts as needed.

Q: Can a bent pin be straightened and reused?
A: Not recommended. Residual stress after straightening makes it prone to fracture under cyclic shear load.

Q: What should be noted during pin installation?
A: Align lug holes carefully, avoid heavy hammering. Seat the pin fully and fit the retaining ring. Lubricate regularly.

Q: Can ordinary round steel substitute this pin?
A: No. Untreated mild steel lacks required strength and will bend or shear easily under impact.
