Abstract

A lock assembly to lock two members together, typically an excavator wear member, such as a tooth, on to an adaptor. The lock assembly has a locking pin with a flange portion and a retaining assembly that receives the locking pin. The retaining assembly includes a locking member, in the form of a locking ring, which deforms radially when a tapered portion of the locking pin is inserted into the retaining assembly. In the locked position, the locking ring engages with the flange portion of the locking pin to prevent withdrawal of the locking pin from the retaining assembly.
