PIN - COTTER (Toyota TY0131031CCCCC)

TY0131031CCCCC: A cotter pin that fails during operation can allow a connected fastener to loosen, leading to unintended disassembly of a mechanical joint. This aftermarket replacement part references the Toyota catalog number TY0131031CCCCC. The pin is a simple metal fastener inserted through a hole to secure a clevis pin or bolt. Its plain mechanical function is to prevent rotation or axial movement of the retained component. A common consequence of a missing or broken cotter pin is the loss of a critical retaining element, which may cause a sudden mechanical failure. Keeping a cotter pin in sound condition helps maintain the integrity of pinned connections under vibration. Verify the serial number or application, then call (562) 693-7748.
