Narrative:
Tire change (nosewheel). Air carrier maintenance manual does not reflect to make entry in the logbook, 'ground pin installed.' that reference is in general procedures maintenance manual. This should be incorporated in maintenance manual. I failed to remove the pin and make logbook entry that pins were installed. Pushback crew failed to notice landing gear pin streamer, pilot failed to see landing gear pin streamer on his walkaround. I have submitted request to change the maintenance manual to add a note: make entry in logbook that pins are installed per general procedures maintenance manual.
