NLG steering tiller installation: Not too tight! 737-3/4/500

When installing a nose wheel steering wheel (tiller),  you must tighten the nut 50-75 lbs/in above the running torque of the nut, with a max of 375 lbs/in, acc AMM.  Sometimes this is can be too high, which can result in a complaint that the nosewheel steering will not return to neutral exactly. The wheel may be running against the sidewall and the wheel turning force could be too high. Try to tighten the nut just that way that the wheel is really free to move, and that is comes back to neutral very easy. Even a very little axial play of the wheel is the ideal way to make sure the system operates smoothly!  But remember always follow the AMM first. You can use this tip at your own risk if you still have problems afterwards.
