Modifying an Impact wrench for more torque (1st attempt)
HTML-код
- Опубликовано: 24 фев 2016
- I've wanted to experiment with improving the performance of this cheap Harbor Freight impact for a while now. In this first stage I improved the air flow from the inlet to the motor. Although there was a noticeable improvement in power, it isn't enough. I'm now working on improving flow through the motor, hopefully there will be enough of an improvement to remove lugs that were installed by a more powerful twin hammer Impact.
Here are some links to good impacts:

*Great **MyBest.Tools** tool, lots of power😄😄 and very smooth*
I used ruclips.net/user/postUgkx4ynqaujg7rZKFapA8s29kTpRszJGa3-K this for the first time today to replace the front wheel bearing on my rwd 98 dodge dakota. This had absolutely no issue removing or reinstalling the lug nuts and it took off the axle nut without any struggle. Sounds like it's got some muscle to it. Time will tell
Man puts a video out about a impact gun thst was cheap n ppl bash him saying you get what you pay for n 1 person talking about a dermatologist. How many of the ppl that bashed him have did did this!? I appreciate you taking youre time to do then even to video up! Some mat not know how to even take one apart also. Its funny how ppl can be cruel or judge just by watching a video. He even told it was a cheap gun n ppl sayin get what you pay for n well some ppl may cant afford a better one n for this guy to get on here n at least try n help i will appauld him n appreciate it 100%. Thanks buddy for the video!!
Dale justice ...Thanks for the kind words.
@@SteveStoltz You're welcome buddy. Keep posting youre videos n i will be sure to watch!!
Dale justice I reread your post and now I remember the guy who was concerned about my dry hands 😂😂 I had totally forgotten about that one. That cracked me up.
@@SteveStoltz Ya i was like this man is working on a impact gun full of oil n more worried bout him goin to the dermatologist than what he is doin. I was like well he may go to a dermatologist like me cause i have severe phoriasis n some times it gets on my arms when i get sick, upset, eat something. I mean i say he meant it in a kind way but you think he would know or at least think you know what to do. Esp n you posting a video. Idk why some ppl comment on a video when it hadnt got nothing to do with it or like the ones saying you get what you pay for. I mean there has been sometimes when i wish i had a cheap torque n hadnt had 2 pennys to rub together.
Thanks for the video, it propelled me to mod some of the other air tools. The pneumatic file worked well, works better now.
Just did similar mods to an identical wrench. Drilled out the screen, drilled the exhaust ports in the motor out to 3/8, drilled two 3/8 holes in the housing directly over the motor exhaust ports, and drilled the number 4 port out to 5/16. I also oiled all the internals with motor oil. Even on standard 1/4 inch hoses and fittings it really rips at 100psi. It's also much louder. I put a 1/2 inch nut in the vise and it ran a grade 2 bolt all the way down to the head, unthreaded shank and all, without any trouble at all.
Don’t know if you’re still reading these comments from the video that’s four years old but you helped me out immensely today! Big thanks!
Glad it helped.
That's my first impact. Still have it, got in a 1995yr set with the CH compressor and 1/4&3/8 ratchets. I don't know why I still have it, other than no one else will want it and still works. Kind of a nostalgia thing i guess. Never did have any great torque, but was better than nothing and did work well on less than 150ft/lb nuts. I have many other impacts now. A lot of great memories fixing cars with it. Now just a tool box decoration.
great video man
Great video. Nobody tries anything anymore. I've never learned more from anything than trying and failing. Keep it up!!
Yeah, there's usually a few failures to every success lol
It seems to be a growing thing that everyone is looking for more and more from there air compressor and air tools, especially the renown impact wrench. I for one have been using the same air compressor and impact wrench since 1998. The only changes to my compressor, is I had to replace the pressure gauge 2 times until I figured out that if I made sure it was positioned correctly so as to not allow moisture to collect due to facing 'down hill' so to speak. I replaced the pressure regulator switch once. Also I learned to use quality connectors. I prefer Milton, not to imply that there are not other quality types out there. Just that they don't sell them at HF. I've had no issues dealing with lug nuts on all my vehicles and my grown children's vehicles. Just so you know, I have a Campbell Hausfeld compressor VS501000 13 gallon 125 psi max SCFM 5.6 @ 90 psi and a Campbell Hausfeld 1/2 impact wrench which I do not know the model number but I purchased it the same day I purchased the compressor. My compressor does not have an out pressure regulator, so I have one attached to a bracket that's hung on the wall so if I have a reason the set the out pressure below what the 125 max, then I connect it to the outline and connect air hose on stored on the reel. I have 100 feet standard 3/8 rubber hose using Milton Hi-Flo connectors. It has served me well and I do not see any need to change anything until it is worn out. I was able to remove all the lugs on a friends 2010 GMC 2500 HD with no problem. I would suspect that if someone threw a 1 ton at me, I may not be able to handle that unless I pickup a higher torque impact, like an Earthquake. Not a mechanic like many of you are and you very well need all you can get out of your tools after all they're your livelihood.
Can't stop staring at the misaligned case halves. Harbor Freight, oh you.
Tnks for the video, can you help me im try to fix the reverse valve bushing they lost and spiring on the pin to pres the valve of can send me a picture disarm tnks
i wonder if drilling the passages in the housing itself would help. also, maybe somehow adding weight to the hammer, maybe migging beads across the back? just throwing ideas out. the forward/reverse switch is pretty restrictive too.
I considered drilling holes in the case, the exhaust seemed to be the most restrictive bottleneck on the outlet side, but since I didn't got to the extreme on the inlet I just settled for opening up the existing ports and machining the outside of the cylinder a bit. I machined the forward/reverse mechanism quite a bit, but the ports that were cast into the housing were hard to reach with anything that I had available.
I am enjoying your video, and I had the same impact for many years. It died, but it was my fault. It took a spill off a ladder onto cement. Anyway, I replaced it with a much more powerful unit. While I like my new impact a lot, I *really* miss the old one as you could not snap off a fastener with it. The new one will snap things at the drop of a hat. Every tool has it's place. It surprises me how much I miss that old impact. BTW, she will crack lugnuts, it will just take it like 10 minutes of banging on each one.
I have to repair twin hammer gun can u show how I can improve my tool
I am repair the penumatics it's very intrested task so I want to know can we improve our wrench
Very interesting. The pneumatic motor may be way undersized for the hammer weights.
Someone mentioned that they bored out the cylinder and did some work to the vanes and it improved quite a bit, so your probably on to something. Unfortunately on mine I have already machined the outer part of the cylinder to the point that there isn't much material left to remove.
You get what you pay for. You can get the Earthquake XT with coupon for $99. Instead I upgraded to the Aircat 1150 and I expect to have a quality product for a long period of time that can actually do the job. You should also upgrade to high flow connectors and couplers and that will provide more power.
It does the job. Excellent product.
Interesting tinkering.
Great video though. I will try the same thing with my gun.
You need a CLECO CWC 500R. 1200 ft/lbs, 2 year warranty and reasonably priced.
I have that impact and its junk. I bought the next model up. The heavy duty twin hammer for about $50. Much better with the bigger fittings.
Excellent video... I have that same impact gun that I bought at Big Lots a long time ago. Cheap and dang near worthless. Thanks for doing the video. I've decided to just invest in a better impact gun.
I have the exact same one looking one as you do, but mine is branded "Air Mounty"...I have found it to be kind of weak too, even though it claims to be rated at 312 Nm / TQ. I might try something like you have done here..
Thank you for sharing the tips
Your welcome, The mods definitely make it usable as a light duty impact for lawnmower blades and bolts you don't want to snap off etc. But for larger jobs there's no substitute for a better impact.
Steve Stoltz - it worked on getting the pulley off my alternator, but for wheel nuts; it feels completely gutless
Steve Stoltz - if you don’t mind me asking; how did you get the buttom fitting out, and the part where you adjust the power?
@@socialghost4400 on mine, the air fitting just unscrewed and the spring and ball just came out. For the adjustment knob on mine, there is an Allen set screw on the front of the grip down from the trigger. Once you back that set screw out you should be able to wiggle the knob out.
I have the same gun, and the same problem. It would have been interesting if you had torqued those lug nuts to a value (say 100 lb ft and 120 lb ft) and note the before and after results.
Yeah I thought about that after the fact, It would have been more helpful to people with something to compare to. It is a useful impact now though, I use it all of the time for lighter nuts and bolts, I don't have to worry about snapping things off with this one.
don't fail to consider how much a quick connect can impact your torque, too. You could try to ream the the wholes in the quick connect like you did the gun, or screw the tool straight into your airline. Alternatively, it could just suck :p I've been relatively happy with the HF "professional" model (earthquake) for working on my little nissan sentra, so I don't think you got pop out near 500+ bucks for a great impact
first thing to do is go to compressor and check the gauge shows 90 psi with the wrench working.. not with wrench sitting idle.... and then make sure you go good air line 3/8th minimum and put the gun to the hose with just a single quick release. quick releasefitting slow down the air so you need to make sure the air line can give the power... put airline direct to tank not through any fittings. go direct or you lose the power... only drill out the one large hole in the setting.. the idea is not for speed but for power. so you can dial it down and not strip out weak bolts/nuts.
OK. I have a 2015 GMC Sierra 1/2 ton 4WD. The torque specs on the lugs are around 140 ft lbs. I can remove my lugs with my Kobalt 1/2 brushless impact that only has 200 ft lbs break away torque. Those lugs nut on that truck are tightened way beyond what is required. So who ever is slamming those lugs on that truck is a jerk.
instead of oil in the nose, use grease.
There's A Recommended Air Setting For Every Gun According To Manufacturers. Too Low Or Too High Can Be Problematic... Not To Mention Rocking Dog Clutches Have Relatively Low Torque Outputs, Which Is Probably Why It Won't Remove Lug Nuts
.
Wtf
You can get a IR TI 1/2" impact used on Ebay for a reasonable price and rebuild it for cheap if it needs rebuilding. IR are the industry standard.
Or at least get the HF Earthquake models. They are supposed to be very decent and modern in design and performance.
Those steel case impacts (whatever brand) are very ancient in design and should not waste time on those. Time is money. And wasted time is stressful. Seriously, just give it to a metal recycler.
I have other impacts, I actually compared this one to an Earthquake in the video. This was just something I did for fun in my spare time. This impact has become my go to for light duty things though, like removing stubborn bolts from lawnmower engines etc. The 700 ft lb gun will just snap the heads right off of the bolts, where this one will gently work at them.
my old ir 231 still going strong after 15 years
and its not a ti I wont get a polymer one either when my 231 dies I think ill get another 231 if they still make them by then
@@MrShaun1578 gay. Get a 2235 timax, run 150 psi, and power the power switch on low when in reverse. It’ll give you enough power to break every socket you own. Keep spare sockets and anvils handy
Cheap air impact wrench has limited hammer power and air motor torque cannot fix. Just push up the compressor PSI to increase a little bit torque. Can't do much to raise the ft-lb torque.
" i got filters and stuff on my line"
Ive never considered myself to be the most eloquent. lol
Nah, just pointing out a potential CFM loss. But, the Impact is obviously crappy, its not your system. i saw that when you busted out the earthquake.
Most impacts use 60cfm
I spent about 600$ on a new snap on impact and it was hit or miss on lug nuts about a week later snap on took the gun back gave me a refund and discontinued the gun
Snap on air tools are mostly trash. Ingersoll for longevity and air cat for cheap power
Don't use a quick disconnect
poor air impact guns you had . air impact wrench Ingersoll Rand 2235TiMAX you need
250 lb ft advertised torque rating is bunch of bologna.
Did you eat any food before you made this video ??? half of the video we cannot hear your words ,
Vg
Hum! I bought a husky air wrench like this and is like shit doesn't work I waste money n´ time
I hear ya
Não mostra como montar nem desmontar
I think yr first and wisest move would be to deal with the Dermatitis problem you have that's on yr hands! Look after your health first, everything else can wait.
Ill ask the manicurist for suggestions on my next visit to the salon. lol
You sure are a wiseacre but I reckon a "manicurist" would likely give you similar advice! lol
Amateurs fix things 3 different ways then give up.
Professionals toss em in the dumpster the first time.
Buy junk waste money.
I have to repair twin hammer gun can u show how I can improve my tool
