Installation Guidelines
Preparation
Ensure all components, such as bolts, nuts, and shafts, are clean, free from debris, and properly aligned before inserting the cotter pin. Select the appropriate pin size according to the hole diameter and material strength requirements.
Installation Steps
- Insert the cotter pin through the pre-drilled hole in the bolt or shaft until the head rests firmly against the part surface
- Ensure the pin legs are evenly extended on both sides for proper balance
- Using pliers, bend one leg of the pin around the bolt or shaft to lock it securely in place
- Optionally, bend both legs in opposite directions for added security in high-vibration applications
- Verify that the bent legs are flush with the surface to prevent interference with moving parts
