Abstract: A lock assembly for an excavator wear assembly, the lock assembly a locking pin having at least one dowel extending outwardly therefrom. The lock assembly also includes a retaining member having a seat and a cavity and a biasing member located within the cavity of the retaining member. The biasing member is adapted to exert a biasing force on the dowel to releasably retain the dowel within the seat of the retaining member.

Abstract: A lock assembly, and wear assemblies including wear parts incorporating the lock assembly, having a locking pin with a dowel extending outwardly that is received in a slot of a retaining member. The slot of the retaining member has a narrowed section which is narrowed to a width that is less than the cross sectional dimension of the part of the dowel that is received in the narrowed section. In use, the locking pin is rotated and the dowel traverses the slot of the retaining member including passing through, or at least being received by, the narrowed section of the slot. The slot may optionally have a seat that receives the dowel after passing through the narrowed section.

Abstract: A wear assembly having an adaptor with a spigot portion is disclosed. The spigot portion has a transverse dimension. The wear assembly also has a wear member releasably mountable on the adaptor. The wear member has a body with a socket cavity and the socket cavity is adapted to receive the spigot portion of the adaptor. The wear member also has a pair of mounting ears extending from the body. Each of the mounting ears has a transverse dimension. The transverse dimension of each mounting ear is in the range 0.25 to 0.4 of the transverse dimension of the spigot portion.

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.

Abstract: An excavator tooth assembly comprises a first wear member and a second wear member. The second wear member is releasably mountable on the first wear member. The first wear member has a lock face. The second wear member also has a lock face. The lock face of the first wear member opposes the lock face of the second wear to define a lock passage therebetween when the second wear member is mounted on the first wear member. The excavator tooth assembly includes a lock pin which is adapted to be received in the lock passage to releasably secure the second wear member to the first wear member.

Abstract: A wear member assembly for a lip of an earth excavating device comprises a first wear member, a second wear member and a retaining pin. The first wear member is mounted to the lip. The first wear member includes a boss extending outwardly from one of its opposite sides. The second wear member is mounted adjacent the first wear member. The second wear member includes a socket in one of its sides. The socket is adapted to receive the boss of the first wear member. The second wear member includes a retaining pin passage in communication with the socket. The retaining pin is removably located in the retaining pin passage. The retaining pin has a first bearing face adapted to oppose and engage a face of the boss received in the socket and a second bearing face which bears against a load bearing face of the retaining pin passage.
