I am rebuilding the outdrive on my OMC Cobra. The tapered roller bearing went bad on the pinion gear. I replaced the bearings and now ready to re-install but I can't a spec on the bearing pre-load. I have it set at about .004" right now but I need to know the spec before assembling. I marked the spanner nut before removing it to have a reference but it's too tight if I move it back to the original position. Any help is greatly appreciated. Robert
