Pitman arm install
I just purchased a brand new steering box for my 1971 Corvette. When I tighten (110 ft/lbs) the pitman arm nut, the nut sits flush with the shaft. On the old one, I can get about 1/4 of the shaft to stick through the nut. Is my new box ok or am I doing something wrong?
Thanks in advance

My Haynes shop manual (1968-1982) says to tighten the pitman shaft nut to 140 lb-ft.
My older Corvette shop manual 1966-1982 (Automotive Resesarch Div., Carbooks, inc., 1982) says to tighten it to 185 lb-ft
My assembly manual (for 1976) says 160 lb-ft Dynamic, 210 lb-ft hand inspection.
Hope that helps

It could just be the tolerance of the rolled splines on the pitman shaft and the broached splines on the pitman arm. If you are drawing the pitman arm onto the pitman shaft splines with 140 to 185 ft-lbs it is not coming off.
