another ? about my 1st 741 build

I am using a digital torque wrench that vibrates at set torque. When the job is done do I leave the pin nut at 15-20" lbs and use red loctite or do I tighten to 120ft lb or so. It looks like my backlash is to tight. I orderd the dvd I saw going around in here, maybe that can shed some light on my issue. Maybe i can get some pics of the pattern. Thanks
