Narrative:
When performing a cockpit door mod it is necessary to remove panels in the nose gear well. Sometimes it is also necessary to remove the right nose gear door retract rod to gain access to the area behind the panels. However, there is no step on the paperwork for the rod removal or install. During the process of putting the aircraft back to normal confign, I simply forgot to reinstall the gear door rod. The aircraft was taken to the gate where the flight crew found the disconnected rod during their preflight inspection. The rod was reconnected per the maintenance manual and no other problems occurred. I did not have a new cotter pin that was required to install in the rod end bolt. When I went to get the cotter pin, I was distraction by helping on another aircraft and never returned to finish my aircraft.

Title: A B737-700 WAS DISPATCHED IN NON COMPLIANCE WITH THE R NOSE GEAR DOOR RETRACT CYLINDER RECONNECTED, BUT THE REQUIRED COTTER PIN NOT INSTALLED.
Narrative: WHEN PERFORMING A COCKPIT DOOR MOD IT IS NECESSARY TO REMOVE PANELS IN THE NOSE GEAR WELL. SOMETIMES IT IS ALSO NECESSARY TO REMOVE THE R NOSE GEAR DOOR RETRACT ROD TO GAIN ACCESS TO THE AREA BEHIND THE PANELS. HOWEVER, THERE IS NO STEP ON THE PAPERWORK FOR THE ROD REMOVAL OR INSTALL. DURING THE PROCESS OF PUTTING THE ACFT BACK TO NORMAL CONFIGN, I SIMPLY FORGOT TO REINSTALL THE GEAR DOOR ROD. THE ACFT WAS TAKEN TO THE GATE WHERE THE FLC FOUND THE DISCONNECTED ROD DURING THEIR PREFLT INSPECTION. THE ROD WAS RECONNECTED PER THE MAINT MANUAL AND NO OTHER PROBS OCCURRED. I DID NOT HAVE A NEW COTTER PIN THAT WAS REQUIRED TO INSTALL IN THE ROD END BOLT. WHEN I WENT TO GET THE COTTER PIN, I WAS DISTR BY HELPING ON ANOTHER ACFT AND NEVER RETURNED TO FINISH MY ACFT.
