PIN - COTTER (Nissan NI00921-44500)

A cotter pin that has loosened can allow a clevis pin to walk out, leading to sudden linkage separation. During a pre-operation check, a missing or deformed cotter pin may be overlooked until a component detaches. Keeping a cotter pin properly seated helps retain a clevis pin in its bore under vibration. This aftermarket replacement part references Nissan as the OE maker and cross-references part number NI00921-44500. The cotter pin is a split metal fastener inserted through a hole to lock a pin or shaft in place. Its plain mechanical function is to be bent open after insertion, preventing axial movement of the retained part. Verify the serial number or application, then call (562) 693-7748.
