Narrative:
I was working the installation portion of the captain side jackshaft assembly (rudder pedal adjustment; crank was jammed). I was working with 2 other maintenance technicians on this job; none of us installed any gear pins; our manuals for our work did not call out for this. I did not see a gear pin streamer in the nosewheel well area which was our work area. I did not enter the main wheel wells or work on the main gear. I reviewed the log page; write-up; and any open log pages in the logbook -- none of these documents made note of pins being installed. On tuesday; I do not recall seeing a streamer on the nose landing gear. Also none of us 3 installed any gear pins; we had no references or reasons to do this. I signed my work off as complete. I was not involved with taking this aircraft to the gate. Note: I am aware any time pins are installed that a log page must be opened. FYI: I would also like to note that during the time we were working this job; my immediate supervisor and manager entered the nosewheel well; both stating that they saw no gear pin present.
