After solving some logistics issues I finally got my air compressor up
and running again.

I want to purchase an impact wrench and am not sure what I really need
for use on my car. Seems like you get what you pay for. My current
need is to remove the bolts holding the crossmember brace under the
oil pan. Just can't break them loose with elbow grease. Without
going overboard what kind of ft lbs of torque do we need to remove
some of these 40 year stuck bolts.

I've got a 60 gal 5hp 2 stage upright 240v compressor so I've got
plenty of air.

If that's the hardest thing you'll have to break free, I wouldn't invest too
terribly much in an impact wrench. I used a 3/4" breaker bar & socket with
about 3' of pipe slid on the breaker bar and broke my crossmember bolts
free with only a little elbow grease.

Actually, knee grease to be exact. I drove the car up on my ramps and laid
on my back under it. I put my feet against the pipe and pushed with my legs
until the bolt(s) broke free.

Other than that, an impact wrench with enough torque to break lugnuts free
is about all I've ever needed, and even the $15-$25 cheap harbor freight
impact wrenches work fine for that.

Lance.

I never thought I'd need an Impact Wrench, but now that I have a good
one--sears model about $75--I use the hell out of it! From loosening rusted
bolts on my lawn mower deck to all sorts of items on the Mustang, I love
mine. I'd say to pay attention to the torque they advertise. The cheap
ones have about 240. I'd try to get one with more ooomph than that.

You don't need one of those Thunder Guns that they use in NASCAR, but a good
one is really nice to have when you need it.

I bought one like this on sale on Black Friday
sears.com/shc/s/p_10153_12605_00919983000P?keyword=impact+wrench

It may not be this exact model, but the ft/lbs and price are close. Good
gun, use it a lot. 100 times better than a cheap Campbell-Hausfeld.

I wouldn't do this. A long cheater bar _will_ break these bolts. Ask me how
I know. Once broken off in the frame, they are a major problem. Buy, beg,
borrow or steal an impact wrench, but resist the temptation to use leverage.
Later,
Dennis

Harbor Freight sells a cheapish Ingersoll Rand impact wrench. It's still like $80, but that's pretty cheap for IR stuff. That's the one I always thought I'd spend my money on if I needed another one. They sure are handy when you need them, although I have to say, the import ones do have a decent amount of torque as well.

I guess a lot of it depends on how much you'll use it. I don't really use mine a lot. I torgue all my wheel lugs off by hand, although I wouldn't have to, but if you're not careful and impact wrench will do a great job of messing up your wheels in a hurry.

If you only need strength, the import ones will probably do fine. If you need strength and long term dependability, the IR one is a good way to go.

I agree with Dennis, there are a lot of things that leverage will not work well with, and can break bolts much easier.

Now that I look, I can't find the cheapish IR wrench, the cheapest one there is $129. Use a coupon or go with one of the HF ones. Some of those composite ones look pretty nice.

That's one great thing about compressors, the ability to use cheap tools that are pretty reliable.

Speaking of air tools, check out the new poly hoses. They're light, small, and durable. I just got a 50' that almost looks and feels like an extension cord it's so light and small (just 3/8" O.D.!). Home depot sells a roll of 100' Amflo poly hose for $37 (and it's only like 5 lbs total!). It's more expensive, but worth it! The old hose feels like a lead weight attached to all the air tools compared to this.

What's the difference? Torque is torque, isn't it?

Not exactly. A torque wrench is a pulsed torque.

For example, if I have a wheel off the ground and need to loosen the lug nuts (a situation I've done stupidly many times), I have two choices. I can use a lug wrench, but I'll need to have someone really large to hold the wheel, or perhaps I can jamb something under the wheel to stop it from turning. The other choice is an impact wrench.

An impact wrench will apply the torque quickly and let off, meaning the average torque is something much less than 400 ft/lbs, or whatever. In fact, it's usually so low that I can hold the tire myself with my other hand while the impact wrench is torqueing.

Why is an impact sometimes able to take bolts off that would otherwise twist off with a leverage bar? I think it's partially because of the way it works. They call it an "impact" wrench because internally the wrench has rapidly spinning hammers that occasionally hit the output shaft to hammer the torque out. This means the peak torque (in the milliseconds) can be much higher than the rated torque. It's like hammering on a nut or bolt, but in a circle. It shocks the nut instead of progressively applying a smooth turning torque.

I was amazed years ago when I was told to use an impact wrench to remove
the big nut on the front of an alternator .... the one holding the fan & pulley on.
This was out of the car, sitting gently in a vice.... it just spun the nut
right off
with out having to hold the pulley from turning

Top nuts on McPherson struts in a Fox Mustang are also a breeze....

Does any one have a site that will explain how to correctly remove a right or left fender from a 66 Mustang?
Thanks
