Questions keep popping up for me about torque, torquing etc.and such questions are always on the edge I being tool questions or procedure questions , so I put it here. 1. Does using a modest drive adaptor such as 1/4 to 3/8 affect the torque process and results... if so.. Higher or lower results than intended. 2. I hear that the middle 60% of a wrench range is where it is most accurate? True? 3. I know that oil on threads significantly affects torque unless accounted for by and directed by the engineers. But are the engineers know that some things such as oil filters and drain plugs WILL always be wet when they creat torque specs? 4. About rotating tires... Is this procedure (I have hand tools only) ok? Or where is it going wrong? A. With car on ground break nuts just loose with breaker bar and socket. B. Lift car, spin off nuts C. Rotate tires to new positions D. Start nuts onto threads a few turns by hand, then using my four way tire iron, spin them snug just to hold rim flat. E. Lower car slightly to put enough weight in tires that the cant spin freely. F. Use torque wrench set to half the final torque To then tighten nuts in star pattern jumping across from each other. G. Lower car fully, set torque wrench to total spec'd torque and do final tighten to spec. Again cossin over to opposite but each time thereby creating a star pattern. I ask because I specifically don't like the idea of spinning on the nuts by hand and then lowering full weight onto tires BEFORE doing ANY real tighten of any kind. It just seems like it would create a gap that then has to be pull against to 'correct' by torquing. Thus my steps E-F a pre torque of sorts....is that A good idea? 5. My Camry says that the transmission over flow tube (which is covered by an overflow plug at a higher torque but not of importance here) needs to be tightened to 7 inch pounds. Yes. 7 INCH pounds. Isn't that LESS than even finger tight? Where do I get a 6mm hex drive Allen socket and torque wrench that low of strengnth?! 6. In general is pre torquing I half torque a good thing before final torque. I am thinking of things besides rims such as oil pans etc. ?
