I am trying to finish out my Chevy 10 blt rear and need some help in converting foot lbs. to inch lbs and to Newton meters. It says tighten pinion nut until it takes 15-25 inch pounds to move it. I do not have an inch pound torque wrench. Can any one convert?
If you divide inch pounds by 12 and you get foot pounds. Foot pounds times 12 gives inch pounds. Never metered my newton so you are on your own on that one.
You need a little inch-pound torque wrench to measure that small of torque. No conversion needed...just the correct tool.
Hmmm... one newton-meter = .736 foot-pounds. So a force of 1 newton, hanging on the end of a 39.37" stick, equals the torque, of .736 pounds applied to a foot long breaker-bar.
I bought an inch pound torque wrench a year ago or so. I could never imagine why youd need such a small measurement and felt I could, as I'd always done in the past, do it by "feel". I'v used it a quite a few times now. You can be much more percise using it and that makes you a better mechanic. Plus inch pounds are so cute....
You want a small scale beam style inch-pound torque wrench. A foot-pounds torque wrench isn't particularly accurate at very low torque settings. The inch-pound click style torque wrenches are pretty much the same. A small scale beam style inch-pound torque wrench is easy to use and a good quality one is quite accurate.
are you sure you want to rely on a harbor freight torque wrench to not ruin your rear end in more ways than one
Just a reminder. You need 15-25 in/lbs rotational torque, not just to move the pinion. You will find it takes more to get it turning than it does to keep it turning. In other words, you need to stay in this range while continually rotating the pinion through several turns. Below this range, too loose. Above, too tight. Also, this is without the ring gear.
Download this, install it, and keep it on your desktop. I use it all the time for lots of different stuff. http://joshmadison.com/software/convert/
I suppose this is inconsequential since no one has mentioned it but isn't the correct term pound-foot instead of foot-pound? I know foot-pound rolls off the tongue easier but it's a little like saying hours-per-mile instead of miles-per-hour. Just being a pest I guess. Everyone knows what everyone is talking about anyway.
Pound-feet or foot-pounds are interchangable. The two terms are multiplied, and the ever-popular commutative property of multiplication tells us order doesn't matter. Damn, I love that math talk......
the two terms mean different things in the world of engineering...but it doesn't really matter how you say it when you're working on cars, we all know what you're talking about
