Narrative:
While assigned to work on B767-300 on jan/sun/03 at XA30, upon a routine inspection, found a worn #3 front maintenance landing gear tire. My partner and I removed and replaced the worn tire per maintenance manual. We replaced said tire outside on a remote ramp area. We returned to hangar, signed off our write-up, and resumed our normal work schedule. Later that day (jan/sun/03), the aircraft was taxied to terminal. Then loaded with passenger and cargo, and attempted to depart ZZZ. The flight crew returned to the gate because #3 brake assembly was overheating. Gate maintenance found the fuse plugs blown on #3 tire. They reported removed the #3 main landing gear tire, found that my partner and I failed to remove the inner tire spacer from the old tire to be placed on the axle before the new tire was to be put on. Maintenance replaced both front tires (#3 and #4) on the right main landing gear assembly, as well as the #3 brake assembly.
