Torque locking system for fastening a wear member to a support structure

An assembly for operatively attaching a wear member to a support structure, wherein the wear member and support structure respectively have a first and second passage which are co-extensive and form a common passage when the wear member is operatively coupled to the support structure, the assembly comprising:

• a pin retainer receivable in the first passage in the wear member, said pin retainer having an outer surface, an inner end and outer end;
• retaining means for retaining the pin retainer in the first passage;
• and
• pin means insertable within the pin retainer and extending through the first passage and into the second passage to operatively lock the wear member to the support structure.

A method for locking a wear member to a support structure wherein the wear member has a first passage and the support structure has a second passage which are coextensive when the wear member is operatively coupled to the support structure, comprising the steps of:

• inserting a pin retainer into the first passage in the wear member whereby the pin retainer is held in non-rotatable position;
• coupling the wear member to the support structure so that the first and second passages are co-extensive;
• and
• inserting a pin means into the pin retainer by the application of torque force wherein the pin means extends through the first passage and into the second passage to lock the wear member to the support structure.
