Gah! getting ready for big front end rebuild and I find my torque wrench only goes to 150ft-lbs and I need 174+ for the axle nut.

Now I weight 175-185lbs. If I was to stand exactly at 1ft on my breaker bar would that be good enough for torquing the nut back on or does this need to be super-accurate? How about guessing the last 25lbs?

Anyone have a trick for extending the range of a cheap torque wrench?

dont over tighten with the torque wrench. if it goes to 150 then torque it to 150 and get a breaker bar and tighten it a little more with that, dont use your torque wrench to over tighten, they are very delicate and will function incorrectly if abused. also, you must always put a torque wrench back to zero when you are done using it or the calibration will be off, and dont ever loosen anything with it either... as for the axle nut, you will be fine, ive removed my axles a dozen times and i never use a torque wrench, well, unless my appendages have that function built into them by now...?

Cheers. I'll take it to 150 and then a little bit more w/ the breaker bar.

you'll be good, just make sure you have someone press firmly on the brakes to make sure nothing spins slighty to absorb the force.

I don't think thats how it really works tho. standing on the bar. 175ft lbs isn't all too much. But yea just get 150lb and a maybe a 1/4 turn more with a breaker bar.

Don't forget one of those locking castle tops that you stick the pin through and prevent the nut from backing out.

there must be some auto store with a loaner program. That will be much easier and better than trying to guess how much you tq'ing a bolt down. Especially when over tighning the axle nut could do damage to your wheel bearings.

or make a thread in the regional, certainly someone close to you has a tq wrench you could borrow for 5 mintues

They do. There's 1 down the street from me. Just went there last night to recycle motor oil.

I wouldn't guess using your weight. Torque = force (your weight) x lever arm (distance ), so unless you got all your weight in exactly the right spot, you could overtighten it.

not to mention that gravity (or force normal) exists perpindicular to the earth, thus your distance would vary depending on the angle of your personal force vector in relation to the pivot and F-sub N.

edit: we have exactly the same number of posts.

174-231 lb/ft. Since when did everybody get **** about being accurate? What about those tire fools who use impact guns on your lugs? There are some people who believe you should be lubricating threads before tq'ing them for more accurate readings. Well, If you don't have the proper tool, get the right tool, or make do with whatcha got, knowing that you won't be factory spec.

Exactly! Same number of posts plus we agree that gravity could be a major component in the calculation! http://forums.maxima.org/images/smilies/jump.gif
