- Review of Harbor Freight’s Earthquake 3/8 air impact ratchet (68426) along with torque test.
Link to my previous video reviewing the Harbor Freight Central Pneumatic mini air ratchet: • Review of Harbor Freig...
Moral of the story. Don't use a air ratchet for lug nuts. They make a thing called a impact wrench and works better with 1/2 impact. Use the right tool for the job and it's amazing what can be accomplished.
I think he's just having a bit of fun seeing what the tool is capable of, but good point
Well he was able to use it on lug nuts and but took time though, well practically just need the stock lug nut wrench and use the good old pipes its easy
Yeah I have a 800 ft lb impact wrench just wanted to see what it can do and try to put some rough numbers behind it.
Yes I drop some air tool oil into the tool’s air inlet before and after each use.
Real 😂😂
Your air inlet is 1/4, change to a 3/8 fitting to get the advertised numbers
That’s a good point. I will take a look at it. I’ve heard that the hose diameter is the largest driver, but every bit counts so a larger fitting would help.
@@homehackshowtos That guy was correct, so you should do a revised video showing the difference between the 2.
@@Hipsters_N_Hippies bigger hose = more cfm to the tool and makes huge difference.
I appreciate all your effort, but as others below have mentioned, your "test" is full of (significant) compromises (in order of significance): hose diameter, air couple diameter, 3/8 to 1/2 adapter (Any adapters and extensions will absorb impact dramatically ), thin wall chrome socket (impact sockets are heavier- better physics - see the Honda crank bolt videos for the visual), and your air volume.
With these changes, this impact will do 70 ft/lbs. all day! You don't have much air capacity, but those first three mentioned here will amaze you. I'm a cordless guy, but recently I did make those changes to my air set up...... I've started purchasing air tools again! (including this impact ratchet).
Roughly speaking, its not the tool, its the air running through it! OR regarding cordless, ...... its the battery.
Thanks for the feedback
Thank you for being very polite, respectful and nice when you disagreed with the test.
You are using an air ratchet for things you should be using an impact gun(wrench)
It's an impacting air ratchet. It's not for lugnuts but it's just something to test the torque specs on
Decent test but those are jobs I wouldn't expect of any air ratchet! Air pressure could play a role.
That's all they use in tire shops...

I did that back in the 90's, many things have changed since then. I work on aircraft, power tools are a good way to really trash very expensive parts.
This compressor is not big enough to run an air ratchet effectively. A 4 gallon compressor is good for brad nailers
Agree for continuous use. The one I am using has a 225 tank psi so it is equivalent to an 8.5 gallon compressor at 120 tank psi.
Psi is irrelevant when it comes to working with air when using air it requires volume to be able to maintain the working psi needed for the tool so if it requires 90 working psi for full potential you need high flow couplers a 3/8 hose and you'll need to set your regulator to like 110 115 psi cause the 90 working psi is the psi that you need at a constant when you have the took maxed out with the trigger wide open and yes any distance that you put from the head of the tool to the nut or bolt is going to lower the amount of torque that you deliver to it
I use an air ratchet all day long no issues using the pancakes. Both busting lug nuts of f150s from other shops dropping the hammer on their guns and swapping over to the ratchet on location. Mine runs it's tank to around 150psi and refills again around 100 where I have it set. Despite it cuts on more, I don't have any issues with mine even when I stay on the hammer it eventually gets it off before it shuts on again. a 4 gallon compressor is good enough for those not only in construction too. Just have to know how to use your tools efficiently to be just as effective.
Please use impact sockets with impact wrench. Also...a tip... Replace your air connections with the largest you can find. Try to use a 1/2 hose. You will see a night and day difference
Yes I need to pick up a pack of deep impact sockets. Right now I’m using a 3/8 line. I will look at getting a 1/2 line. Thanks
Totally unnecessary been using chromes on my 3/8 gun at work for 6 years and have yet to wear out or break one. Also the recommended psi is working psi, not static. This means you should be at 90 with the ratchet running. Sometimes regulators on small compressors just don’t move enough air. Also breaking torque is not always equal to tightening torque. On lug nuts unless your tires get removed frequently it will almost always be higher. The great thing about air ratchets is you can crank on them to break things loose. That is often the better option to loosen nuts and bolts. Most of the advantage is in the speed of removal.
@@TheDannymarine90 yes, that is good info. I'm needing to get some tight bolts loose. 😁👍
Was your compressor set to 90 pounds static pressure or working pressure?
Excellent review!!
Man my 20 year old snap on air ratchet would break those loose like nothing ! But you have to be really strong otherwise it will smash your hand .Keith
Appreciate the comparison. I’ve never had the privilege of using snap on tools.
Break the fastener free with the wrench before pulling the trigger.
I find it strange...I went to Home Depot and Lowes, but none of them have any air ratchets.
My local Home Depot carries Husky 50 ftlbs air ratchets and 80 ftlbs impact air ratchets.
Your testing is scientific other than the fact that you used an insufficient air compressor (CFM) and did not use impact sockets on the lug nuts. Impact sockets actually matter.
Can you regulate speed from handle or is it just one speed from the go???
Yes it’s a variable trigger
when trying to see how much its tightened the nuts to. have your socket marked and a mark on the wheel.. then see what torque it can take before you move it more... undoing a nut does not take the same. i. e a 50ft lbs torqued nut will not need anywhere near 50ft pounds to undo it. normally takes about 35 to 40 will undo it...... air ratchets are not meant to be used as impact guns. 2 totally different tools... air ratchet is to speedily do the nut up ready for the torque wrench .. and dont use normal sockets with air tools....
Good idea on the marks. Yeah I was just trying to put rough numbers behind it’s strength. I have an impact and impact sockets but this was just a quick comparison.
Use the right tool for the job.
The unseating torque will always be lower than the tightening torque for most screws. Loosening the lug nut at 30 ft-lbs doesn't mean that the air ratchet was only able to tighten it to 30 ft-lbs. Try the same with your torque wrench. Try tightening it to 65 ft-lbs and see how much it takes to loosen it.
Yes I’ve heard it takes 20% more torque to loosen a nut vs tighten it.
@@homehackshowtos Its the other way.
It will only be lower if you take the bolt off right away. Just waiting a day and a half. it takes 10% more torque to loosen the bolt. And this can increase to over 50% to even 100% depending on the length of time the bolt has been seated and the thermal conditions.
@@BeastOx213 But he _does_ take the nuts off right away. So the whole test is deemed to fail. No matter what else is wrong with the test (air and whatnot).
@@Tetraden-a Exactly my point. 👌
You got a little compressor too small for this air ratchet
Isn’t the proper way to use a ratchet is to use it like a normal ratchet and the air part to assist after breaking free the bolt or nut?
This just feels wrong. I’ve never been a paid auto mechanic but always used non-air tools to break loose or for final torque and just used air for speed in between.
Most of us use electric or air tools for almost everything, time is money and if we break something with it we usually have a backup to fix our mess up lol. We do use torque wrench's in critical areas though (head bolts, driveline bolts etc) and long breaker bars and heat for things that just wont budge with power tools.
Why do you say gallon, pound, and fahrenheit, but you also say tons?
Müller Volker Ton is also an empirical unit of measure
gallon pound ton and ft lbs is imperial.. and the best system to use.. it was the first system used in mass engineering..... remember the majority of proper industrial engineering was middle england. not europe and definitely not usa... industrial revolution was ENGLAND and Scotland..
lol you have to break the nut loose these are not made to break it free, I heard about reviews like this but this is the first I have come across
WELL NO SHIT youre using a 3/8 to 1/2 adapter thats gonna rob alot of torque
Air tool oil?
Another guy just trying to throw off on Harbor Freight tools. Their stuff is cheap. Most of the time you get what you pay for. This guy has no idea what he’s doing.
Do you know how to do it better?
Just trying to put rough numbers behind the tool rather than just talking about the tool.
@@homehackshowtos I loved the video. Great job. I now own the same tool.
@John Cameron, don't be a hater!
Everyone got to hate on a guy... Just keep scrolling if you're so much better! Good hell you a$$hole mechanics would rather kick the guy, than appreciate what he's trying to do... Sure, there are better ways, I'm sure he is well aware. Good job man. I hope you take some of the nicer things said into consideration, and just let the others go! People always gotta 1 up... "My D!ck is way bigger than that". Says the guy packing 3"!
the small extension rob you of power
Not accurate at all. It can take as much as double the torque to remove as it takes to install.
yeah I bought a much stronger air ratchet and now I tighten all the bolts to hard and my coworkers cant get them out. I think they are going to start beat me up because it was a a$$hole move.
What size air compressor do you have?
Rodolfo Villa Outdoors a Dewalt. Here is a video of it ruclips.net/video/qbfQh_IMaPQ/видео.html
Diyer trying to be mechanics kill me
What’s your point? Are you implying that non-mechanics shouldn’t work on things themselves? Not sure what your point is.
Takes more force to loosing a number t than tighten it
