I'm assembling the rear suspension and need to get 185 ft-lbs on a few nuts and bolts. I don't have a torque wrench and the closest NAPA only stocks up to 150.

I have a 750 CH impact gun. Is there one of the settings 1 thru 4 that'll approximate the 185 ft-lbs.

I really need a quick reply please.

Thanks

 

Check a rental store??? I have no clue how tight an impact will go. Check Sears and get them as tight as you can for now.....????

 

Get it to 150 ft lbs, and keep going.

 

Home Depo 250 ft/lbs tourque wrench IIRC 80.00-100.00 bucks

Iv used it aslot on this truck everything bigger

husky pro was the brand Im shure theres lots better ones out there but

 

Thanks Blade. I'll put that on the wish list. Looks like a good combo of price & versatility.

For now I just went with the gun till it stopped moving. Done!!

 

Proper size socket on a one foot breaker bar and have someone weighing 185 lbs. stand on the end of the breaker bar.

 

I wouldnt worrey to hard sinc e just a leaf spring good and tight just fine

It was a must for my Ball Joints I didnt want to create a steering problem
Seams like that lower BJ was 168ft/lbs to

 

Somebody, knows about moment forces.

Pop quiz: Now how much torque would be exerted on the nut if that same 185lb person were to jump (fall) onto the 1' bar from 2 feet above the breaker bar?

 

I figure the amount I save on labor justifys a couple tools here and there

 

Enough so you'll have to buy a new socket......

 

I couldn't agree more. Doing your own work more than pays for some good tools!

Piolot: A lot of gear-heads have at least one torque wrench floating around, surely one of your friends/coworkers has one you could bum for a few minutes. Just a thought.

 

Or stud LOL

 

The money I saved doing this myself went towards a set of metric and sae deep impact sockets for the impact wrench, and will pay for an electrician to hook up the 6hp CH 60gal air compressor a relative gave us

The little pancake compressor earned its pay today I can tell you.

 

Studying on the pop quiz. doesn't seem too hard to figure speed of the person falling for 2ft (I havent done that yet either) but how long does it take them to stop?

 

Hint: Gravity's acceleration is 9.8m/s^2 or 32.2'/sec^2

Think of it this way instead: think of it as an instantaneous transfer of force, a dude is transferring 100% of his falling energy to the bar, so once that energy is transferred the dude is no longer part of the equation.


Does that help any?


Now in the real world you would never see 100% efficiency in the transfer of energy, the guys knees would bend and absorb some energy, and the bar would bend a little also absorbing some of the energy but that's really splitting hairs and incalculable requiring real world experimentation specific to the guy and the system as a whole. Theoretically though we can calculate this and get close enough.
