When I bought my first new air tools, I bought all IR, mostly because the older mechanic who was kind enough to mentor me had a full set of IR tools that he bought when he first got started decades ago and they all still worked. The company has been around forever and all the parts to rebuild them are still available. The only time I've had to crack any of them open is because an old shop that I used to work at used line oilers and filled them with Marvel Mystery Oil. The ingredients are a mystery to me, but they made all the seals in all my air tools swell to the point of no air getting past the triggers, so I had to replace the gaskets and o-rings in all of them. But that was about 13 years ago now, and they all still work beautifully after receiving daily beatings.
Great video. Good for you for rebuilding a great gun. I just rebuilt an ir 231 model a. Trick to getting the motor in and out smoothly is to heat the housing with a simple propane torch. Then it goes in and out much easier.
One of the beauties of creating a video of the disassembly is if something doesn't go right, meaning I forgot, I can quickly replay it and figure out where I went wrong! Another great video and narration by Eric at South Main Auto Repair!! Thanks Again!
Starting at about 7:40 I'm relieved that I'm not the only one, (1) who tears stuff apart not being 100% sure how to do it, (2) uses a pair of pliers as a hammer. Great video as always!
Why do I have that odd feeling, THAT IMPACT DRIVERS, EVERYWHERE, ARE BEING DISMANTLED AT THIS VERY SECOND?? And in other news, AMAZON was overwhelmed with new orders for impact driver repair parts, just as the new year approached!! A spokesperson for AMAZON said that there has never been anything like this before, and the company has no explanation for this odd event! ;-)
This was an interesting change of pace for the SMA channel! Love it. BTW, I did just recent switch my patreon contributions over from another creator to you on account of not being a corporate puppet and not trying to do stuff with your channel that takes it away from what it started as. Keep being you.
My dad always used I.R. When I went to work that's what I bought. Still have my first impact. Only thing I changed has been the anvil. did it about like you did. i never had good luck with air ratchets. Once worn out toss and buy a new I.R. Thanks for sharing.
I absolutely love it! You are one of us for sure. I especially liked how you had to select the proper size pliers to use as a mallet on the screwdriver drift.
Really enjoy you taking us all along for the ride. Especially like the way you think out loud, helps us understand your logic and way of looking at problems.
I still have my 1972 CP 1/2" , and a 3/8" butterfly (offa the ole Mac truck) they still work great, I'm 70 yrs. Old, I'm thinking I might have gotten my $$$$ worth, here soon, wweeelll sseee. Thanks Eric, love all your stuff. "GARY IN OREGON"
Over 3000 views in a couple hours. That's a good return on investment for marketing. All viewers have some sort of mechanical interest. Better return than investing in NASCAR sponsorship.
Just starting wrenching and I just bought a ingersoll rand 231G from tractor supply for 129.99$ on sale and I hope it lasts as long as yours Erick I’m loving it so far
I was going to comment about how brave you are to go beyond pulling out the things with the notch up, then you picked up the pliers and my hopes died and I doubted you for the very first time. Then there was all the unrestrained twisting and banging and the "beauty marks" as you called them. I asked myself if maybe Astro or whomever might restore the thing to impress us, your subs. The rest of your struggle with that armature(?) added nothing to our hopes until you were able to reinsert those fin thingies. Then, despite that captioned warning. It all went together and you restored my faith in South Main Auto and your unfailing auto-mechanical genius! I just wish I could afford to drive the thousand miles or so to have you attend to my new/old F-150. Life just isn't fair. Happy New Year and thanks for every time we see a video.
Rebuilt many of those! Worked for a company that used those impacts on their production plastic molding machines to pull the molds apart. 48 1” bolts every 7 minutes! But that was 40 years ago, and they look the same! Great tool!
"..to the shop. Today, a treat especial" I literally had to finish the line to restore order in my personal comfort. I could not let the video run without that. Also, the "errrr click!" was a literal click.
I have one just like it. I took mine apart once due to being locked up. Part of the cage where the hammers run was broken. I removed the offending piece and it still works. They’re tough guns. Oh and I paid $50 for it used 20 something years ago.
Wonderful video!! Thank you so much for sharing your love for a first impact and taking the time to correctly place the gaskets and pack the bearings!!
Have rebuilt this platform since the early 90s . That 3 piece gasket is starts as one pinched between the hammer housing and spacer that is pressed fit into the housing. The air vane cylinder is best left in when removing the rotor to keep the lower end plate aligned to the housing bore and will assist on reassembly. If you really wanted to wake this thing up remove the e clip from the rotor end plate remove the bearing lap both end plates with 300 grit on a flat surface to remove any grooves finish with a 600 grit. Then use a wheel cylinder hone to clean up the vane cylinder take the vanes to the 300 grit and lightly clean the seal surface. A couple drops of 10w30 on the bearings reassemble dry. Now you have to seat in the vanes WD40 with a straw applicator a light squirt into the air inlet. Hook up a regulated air line or or one with a tap. Plastic tie the trigger full open put it in a vice or lay it on the floor 40 psi or mid throttle let it rip 5 min in fwd then in reverse. Now the vanes are seated give a light dose of air tool oil 3 to 4 drops and continue to do that over oiling the tool will degrade the performance then grease the hammer push the drive into the tool grease the tool until the drive pushes forward then stop you can actually over do it and tool performance will suffer.Now your IR is better than new. 300 ft lbs now 400 ft lbs.
Love the get in there and give it a go and explore how the tool works and can be disassembled ... just awesome! I'll look this one up when I need to service mine.
If this had been a Binford, they would've sent you the C6 Turbo Hydromatic Torque-flite turbo encabulated anvil, guaranteed to flip the vehicle right off the rack .....
LOL I buried an AIRCAT in the backyard out by the fence(with full Honors)....It perished after 3 operations. Finally called it{time of death} and let the poor beast RIP!
And all these years I thought I was the only guy took stuff apart to "fix" it and well just kept going. And was amazed when it worked after I got it back together. The thrill of those oh crap why did I do that moments.
For many years I had the IR 244 which is similar, runs a little slower but has a little more hitting power I believe, my anvil twisted off one day which rather proved the point that stuffing lots of air pressure into it gave it a lot of magic beans !. I ordered a new anvil and that portion of the tool is very easy to work with as I found out. Some years later the three case screws backed off with the vibration ( probably never get them out if loctite was put on them ) and air leaked past and lost power, figured out the issue but it had blown the gasket. Had to buy a rebuild kit just to get the gaskets but when I used the whole kit and took the motor apart to replace bearings and the motor vanes I discovered that the motor case was worn badly as in out of round in the area where the ports are and the only fix was a new motor case, up here in Canada that one part cost as much as you replacing your whole gun Eric. Needless to say I retired that gun as it was not worth pouring the money into and bought the composite IR and have been extremely happy with it in the few years I have owned it. I see a lot of comments about being so surprised about greasing these guns, well they are designed to be greased as the grease goes into the hammer/anvil end for that action through the hollow motor shaft passage way, the oil into the air tool opening lubricates the motor vanes. I had even bought the mini grease gun and the special grease from IR way back with that IR 244 and greased and oiled it often, seems the only way to give those tools enough oil for the motor to live the longest life is by having an oil injector/mister into the air line but then that shops air line is no good for blowing straight air or inflating tires but that. Excellent real life tear down video of a well used/abused tool !
Good video mr. O. I used hf parts to fix a ir 1/4 drive air rachet years ago. It was before the internet, still works today. I guess most air tools are copies of ir.
I still have my Campbell-Hausfield impact I bought at Walmart for $65 back in '01. NEVER oiled or greased the thing until just recently - never knew you were supposed to HAHAHA! Didn't know what that strange fitting was on the side until about 9 years ago, lol. Thing never let me down though! Can't believe it lived as long as it did with zero grease in it. Guess the factory actually put some in, and it was actual quality grease. It now lives in the back seat of my truck in case I ever get a flat - I've got a set of Viair air compressors in the bed. I used that impact daily for close to 10 years before I bought my IR 2135 TiMax - that one is now almost 9 years old, but I've kept up on the maintenance - she cost me just a bit more money than the CH unit. Haven't had either one apart yet - figure I've got another 10 years before that needs to happen. 😁 Ahh who cares where the gaskets go - it worked! 👍👍😊 Nice job! Set for another 20 years, at least. 😜
My IR 231 is somewhere around 50years old! Put in one anvil and one set of vanes. Still use it ,still working fine. Oil it occasionally is all it gets.wish I had a dollar for every wheel it's taken off ,not to mention the on told amount of other bolts and nuts it has hammered off and on. 40 years as mechanic at Chevy store followed by ten years mechanic in at auto auction.
If you ever need to do this again, put the shaft of the air motor in the vise and pull the housing off. works way more betterer... I have done literaly thousands of these. Good job tho, it woorks!!!! Thanks and happy new year!
@South Main Auto Repair LLC just don't understand; he KNOWS that Robert is his mother's brother, he KNOWS the close-ups don't work without telling them to "enhance", how could he forget "Tappy Tap Tap"? That end of the impact would have literally fallen apart if he'd used the magic words! I wonder if he's getting enough sleep at night? Maybe Mrs O should make him some soothing brakecleen and fluid film tea before bedtime?
This style impact is bulletproof, oil it often, give it a shot of grease now & then to pad the hammer parts and it will last a long time. I use the 231C and its hard to beat the price (125) and it has a decent amount of power.. My first air gun was a worn out CP 741/749 before getting IR 231/261. The vane kit is fairly inexpensive, the hammer kit seems to cost as much as a new tool LOL The new tool is imported but still quite reliable.
great job for 1st time .i have one when i fist starter too overhaul couple years ago still working but i now bought a nitro cat i will not go back so much power & so light i'm a gm tech for 33 years
Those holes in the housing that the drum with the fins spins inside of is the air escape, they affect the torque(?) that is applied when spinning in each direction. If the holes are closer to the clockwise direction, it would be less spinning in that direction than counter clockwise, and vice versa.
I've had my IR 231 for 23 years now, only had to replace the anvil. I had replaced the hog ring but the sockets still kept falling off so I changed the anvil and all was good, still works to this day. I think IR makes the best pneumatic impacts. I heard a lot of techs now are switching to the cordless impacts now. I just don't know if they have the power of the air powered ones.
i could be wrong but--- i believe there is a pin missing that aligns the front and rear of the motor assembly and the barrel of the motor. the offset on the barrel is so it has more torque in the reverse direction. so if you put it in backwards you can put things on that wont come off lol. and that grease fitting in the back- it goes through the motor through the anvil to grease where the hammers hit. ive wore out a couple of guns in my lifetime always had the 231's every time the thing needed fixed they would break off the lower right cover screw. not sure why. always had extras on hand. anyways thanx for bringing us along
At 24:25 if you close your eyes you can imagine the ricer with the extreme negative camber going by. Nice work Eric that should totally last at 20 years or 5 Honda crank bolts
Great video! The hammer pliers were awesome. Where the pliers from Astro? Seriously, thanks for the tool break down since I have never seen the inside of an impact gun.
And it still worked with the two rings in the wrong place lol, i bet you have swapped them back now :-D Thankyou for all your videos, clever, funny, and mad all at the same time :-D
Nice. I had a Black and DEcker model from the 70s. Couple years ago, a plastic piece broke in the air control side. Didn't seem to be any parts available or any guns found on eBay to cannibalize. I tried to rig up a replacement part , but no go. The housing sits now in a pile of stuff my grandsons play with ( has a good handgun profile), and I now own a Harbor Freight replacement. I'm an old DIYer so I expect I won't need another new one.
I wanted to get the thunder gun when I bought my IR...but I went with the cheap 231C for around $110. It’s a good gun for the price. I have had different brands and this is the best yet.
I worked for IR in Athens, PA back in the late 1980s to early 1990s. We shipped thousands of impacts every year and I always wondered, where the heck were they all going. Surely every mechanic and DIYer in the world already had one but we kept shipping. By the way...Eric, free running the tool doesn't tell you it is back together correctly; need to run a torque test as your final test. Enjoy your videos man!
5:10 That looks very familiar to me as at one time I serviced vacuum pumps. Rebuilding is a new set of vanes and polishing the rotor on a lathe with wet / dry 600 grit.
Hey, if it fits and runs....get it back together....you can always play back the video to see how it came apart......LOVE IT!!!.......Mrs. O might have been able to help ya out?
I gotta try and get away from you tube but your videos are so damned informative and addictive!! I wish you much continued success for SMA through 2019 and health and happiness for you, the boss Vanessa and your kids :-). Ford Diy'er- across the pond in Southampton. England
My IR impact gun looks exactly like that one, except with a rubber cover over the handle. Often wondered what it looked like on the inside. It's been a great gun over the past 15 years of my intermittent DIY auto repair uses. My only beef with it is the torque adjustment that's built into the reverse switch. I like having the reverse torque up high and the forward torque down low (breaking lug nuts free vs. installing them lightly before using a torque wrench), and when I adjust the setting for one direction, it seems to change the setting for the other direction as well.
Okay after 30 some odd years I think ill take my IR apart and clean it. Never even had the boot of to notice if there was a grease fitting. Thanks for the video tutorial
There is method to his madness. By captivating us with his videos, he also has a video record of the steps and placement of the parts - yes, Eric is far from crazy.
Ive put together motors that are a similar fit, its nearly a line to line fit and you need to be very straight to get it to slide together..I use to play with the pneumatic die grinders the same way. My kinda mechanic.
great video Eric! i have one of those same impacts mine fell apart so was laughing at you trying to knock the rotor out! i do oil mine everyday i had no rust in mine! Cheers!
Reminds me when I took apart a windstar power steering pump with those fins, assuming astro affiliated with IR -didnt know that but I have both on my shelf..nice to see some fiddling without having to be frustrated, torque still 👌??
Good Video Eric, I have to say you definitely have an adventurous spirit. Air tools for me are a love hate thing, I love it when they are working and hate them when trying to fix one. All strange components for sure.
I don't use that Lucas air tool oil. I took a piece of scrap metal and polished it to shiny bare metal. In three different areas I placed one drop of Lucas air tool oil, one drop of Ingersol rand air tool oil and one drop of Top Ring air tool oil. I did not distribute the oil depending on the wicking action. I then set the metal in the weather for several months through the Canadian fall. On examination, the Ingersoll rand area which had expanded to an area about 4 inches in diamater was shiny. The Top Ring was a close second. The Lucas patch had a large accumulation of surface rust to the entire area.
IR 231. The god of the impacts Repaired these for yr’s. You must heat the shell slightly to get it out. Freezer the cylinder and bits & heat up case to reassemble.
You forgot to throw a little oil on the cross bolt (direction change bolt/part/piece) to help free it's motion. Made a big difference when I did mine, don't shove grease in there, it'll find it's way in eventually but, some tool oil on either side while it's all apart will make you happy. 😀 The secret is to not remove the vane housing/motor in the first place. 😆 Just flush it with brake cleaner/solvent until it runs clear, spin it around, etc. until it's reasonably clean because, when you re-lube everything after disassembly and cleaning, you just shoot some grease in the back fitting with a mini grease gun, as that rear grease port's whole job is making sure that bearing gets greased, since you can't grease it from "the front" when you disassemble the tool for its routine maintenance (every 48hrs of run time), as you're doing here, sans beating the tool to death to remove a part that only comes out if that bearing goes bad, which only happens if you don't grease it regularly through that rear grease port. 😆 The way that part comes out is with a special puller that reaches in, like a bearing puller, hooks under the vane housing and you pull straight out. There's a small slide hammer type tool for little jobs like that. Finding one is another matter. 😀
Nice. Interesting how they work. You improvise very well, lol. Would have been nice to see you try it out. Just hope the new piece holds up like the old one. Thanks for sharing.
Excellent video this is something we really need it goes along with working on cars you must have a great tool in working order to do the job correctly. Thanks for the great videos...
Those plastic parts are called Vanes. Just like a air/vacuum pump. usually made out of carbon and expensive, they wear kind of like brushes on a motor. But that is for pumps, I'm not sure about an air motor. cool video, never took one of my impacts apart.
Very cool I've done that on a few of the old IR231'S though one of them didn't work after and the other I just changed the anvil which was no problem. If you bought a Mac 3/8 impact for $100. that was a heck of a deal I've priced them out here and they're over $200
The exhaust ports in the bottom of the cylinder looked like they were offset to one side a bit, if so I’d imagine the cylinder is in fact directional as the timing of the exhaust ports would affect power in one direction or the other.

@@TractorWrangler01 it's funny...the only reason one might prefer to have someone else do it is for the Warranty on work and parts.
just think if you had a lathe you could of made the part yourself cheaper
@glyn watkins cheaper than free...

When I bought my first new air tools, I bought all IR, mostly because the older mechanic who was kind enough to mentor me had a full set of IR tools that he bought when he first got started decades ago and they all still worked.

16:07 Hole offset does matter. It biases the power output on the rotor rotation. Hence why it has higher reverse torque.

Another great video and narration by Eric at South Main Auto Repair!!
Thanks Again!
"There's your problem lady, some ding-dong's put the gasket in wrong"

Had my IR for 20 some years. My foreman said buy a good one first up. Never missed a beat. Love it.
I was gonna post an AvE reference.. but I see that's already been done a few 100x

i would have to agree watched Eric for so long i broke down an bought the 1/2 impact and 3/8 impact
Yep, he's the reason I bought the Onyx 3/8" impact and use it constantly.
Agreed. Can't wait to get a 3/8" drive nano for work
I've got the exact same impact gun....... Now, I can confidently take it apart and clean it thanks to your highly detailed tutorial!!! :D

"gentlemen, welcome back. (slams tool onto bench)" AVE fan maybe? or just coincidence?
AvE is the best(or worst) thing that came to RUclips in recent years
SMAvE
Eric's version of a video ender could be "Keep your ding dong in a vice little fella". lol
"..to the shop. Today, a treat especial"
I literally had to finish the line to restore order in my personal comfort. I could not let the video run without that.
Also, the "errrr click!" was a literal click.
I almost thought it was AvE for the first couple of seconds...
If we "...really didn't know what we were doing.." but did it anyway, that's called learning. Good job Eric. Thanks.
I expected it to be full of beans
that's was the sales department.....
Qusin111 - Would those be... FULL beans?? (Runs for cover).
It’s the mechanical version of the ‘magic smoke’ in electronics 😂😂😂
Maybe the black goo was what happens to the beans when fully given
Nice to see maintenance on old tools. Astro are heroes for finding the correct anvil!
I noticed that when your needle nose hammer wasn't getting it done, you switched to the channel lock hammer...best invention ever.
I have one just like it. I took mine apart once due to being locked up. Part of the cage where the hammers run was broken. I removed the offending piece and it still works. They’re tough guns. Oh and I paid $50 for it used 20 something years ago.
Have the same impact gun had it sense 1992 and still going strong as always great video
Oh yeah, she's good as new now! That was fun sir. Thanks Dr.O!
Nothing wrong with a little rebuild action. IR's are one of the best guns I have ever used.
Wonderful video!! Thank you so much for sharing your love for a first impact and taking the time to correctly place the gaskets and pack the bearings!!

Didn't know what that strange fitting was on the side until about 9 years ago, lol. Thing never let me down though! Can't believe it lived as long as it did with zero grease in it. Guess the factory actually put some in, and it was actual quality grease. It now lives in the back seat of my truck in case I ever get a flat - I've got a set of Viair air compressors in the bed.
I used that impact daily for close to 10 years before I bought my IR 2135 TiMax - that one is now almost 9 years old, but I've kept up on the maintenance - she cost me just a bit more money than the CH unit. Haven't had either one apart yet - figure I've got another 10 years before that needs to happen. 😁
Ahh who cares where the gaskets go - it worked! 👍👍😊 Nice job! Set for another 20 years, at least. 😜
My IR 231 is somewhere around 50years old! Put in one anvil and one set of vanes. Still use it ,still working fine. Oil it occasionally is all it gets.wish I had a dollar for every wheel it's taken off ,not to mention the on told amount of other bolts and nuts it has hammered off and on. 40 years as mechanic at Chevy store followed by ten years mechanic in at auto auction.
If you ever need to do this again, put the shaft of the air motor in the vise and pull the housing off. works way more betterer... I have done literaly thousands of these. Good job tho, it woorks!!!! Thanks and happy new year!
NO doubt, you are already a valued member of the Astro team! Hope you and the family had a great Christmas! James
That part would have come out a lot easier if you said "tappy tap tap" while pounding on it! Merry Christmas and Happy New Year to everyone at SMA!
վհգհ. պճթ. ատ
@South Main Auto Repair LLC just don't understand; he KNOWS that Robert is his mother's brother, he KNOWS the close-ups don't work without telling them to "enhance", how could he forget "Tappy Tap Tap"? That end of the impact would have literally fallen apart if he'd used the magic words! I wonder if he's getting enough sleep at night? Maybe Mrs O should make him some soothing brakecleen and fluid film tea before bedtime?
Love these "On the side" fix it vids...Pls do more...
This style impact is bulletproof, oil it often, give it a shot of grease now & then to pad the hammer parts and it will last a long time. I use the 231C and its hard to beat the price (125) and it has a decent amount of power.. My first air gun was a worn out CP 741/749 before getting IR 231/261. The vane kit is fairly inexpensive, the hammer kit seems to cost as much as a new tool LOL The new tool is imported but still quite reliable.
I have allways had and still have a IR 231 in my box I have them with a 2 inch anvil and use it for tire work. Best gun for tires.
You're the best. Click torque to spec. And then you went through all four gears and floored it..lol...
great job for 1st time .i have one when i fist starter too overhaul couple years ago still working but i now bought a nitro cat i will not go back so much power & so light i'm a gm tech for 33 years
Those holes in the housing that the drum with the fins spins inside of is the air escape, they affect the torque(?) that is applied when spinning in each direction. If the holes are closer to the clockwise direction, it would be less spinning in that direction than counter clockwise, and vice versa.
I've had my IR 231 for 23 years now, only had to replace the anvil. I had replaced the hog ring but the sockets still kept falling off so I changed the anvil and all was good, still works to this day. I think IR makes the best pneumatic impacts. I heard a lot of techs now are switching to the cordless impacts now. I just don't know if they have the power of the air powered ones.
obviosly Mrs O didnt have anything for Eric to do, He was having way too much fun playing with the impact. Great vid and keep em coming
i could be wrong but--- i believe there is a pin missing that aligns the front and rear of the motor assembly and the barrel of the motor. the offset on the barrel is so it has more torque in the reverse direction. so if you put it in backwards you can put things on that wont come off lol. and that grease fitting in the back- it goes through the motor through the anvil to grease where the hammers hit. ive wore out a couple of guns in my lifetime always had the 231's every time the thing needed fixed they would break off the lower right cover screw. not sure why. always had extras on hand. anyways thanx for bringing us along
richard cranium pretty sure the pin your talking about went back in to align the gasket at the bottom before he put any of the motor back in.
I used to love my IR231
At 24:25 if you close your eyes you can imagine the ricer with the extreme negative camber going by. Nice work Eric that should totally last at 20 years or 5 Honda crank bolts
Rejuvenating that will have a positive 'impact' on the environment, rather than end up in landfill 👌
Sometimes the best way to learn is to just jump in... Awesome video Mr. O!
Great video! The hammer pliers were awesome. Where the pliers from Astro? Seriously, thanks for the tool break down since I have never seen the inside of an impact gun.
And it still worked with the two rings in the wrong place lol, i bet you have swapped them back now :-D
Thankyou for all your videos, clever, funny, and mad all at the same time :-D
Of course :)
zx8401ztv saw that too. Eric the the greatest!!!
Not
You can bet that ring has a new home forever!
it lives on to ugga-dugga another day!
Actually, the offset of the exhaust holes is what causes higher torque in CCW versus CW direction.
Good thing we put it back where it was then haha. I assumed there must be some sort of reason other wise they would be in the middle right?
@@SouthMainAuto exactly! By the way, Happy Boxing Day.
Nice. I had a Black and DEcker model from the 70s. Couple years ago, a plastic piece broke in the air control side. Didn't seem to be any parts available or any guns found on eBay to cannibalize. I tried to rig up a replacement part , but no go. The housing sits now in a pile of stuff my grandsons play with ( has a good handgun profile), and I now own a Harbor Freight replacement. I'm an old DIYer so I expect I won't need another new one.
I wanted to get the thunder gun when I bought my IR...but I went with the cheap 231C for around $110. It’s a good gun for the price. I have had different brands and this is the best yet.
I worked for IR in Athens, PA back in the late 1980s to early 1990s. We shipped thousands of impacts every year and I always wondered, where the heck were they all going. Surely every mechanic and DIYer in the world already had one but we kept shipping. By the way...Eric, free running the tool doesn't tell you it is back together correctly; need to run a torque test as your final test. Enjoy your videos man!
Eric O
Nice Vijeo :) I feel a competition coming on with Ave. Sawsall some new boxes open...lol.
5:10 That looks very familiar to me as at one time I serviced vacuum pumps. Rebuilding is a new set of vanes and polishing the rotor on a lathe with wet / dry 600 grit.
Something beautiful about worn metal parts.
I have owned Ingersoll Rand impact since early 70s only replaced Pat's in it once. Still working.
Hey, if it fits and runs....get it back together....you can always play back the video to see how it came apart......LOVE IT!!!.......Mrs. O might have been able to help ya out?
I gotta try and get away from you tube but your videos are so damned informative and addictive!! I wish you much continued success for SMA through 2019 and health and happiness for you, the boss Vanessa and your kids :-). Ford Diy'er- across the pond in Southampton. England
My IR impact gun looks exactly like that one, except with a rubber cover over the handle. Often wondered what it looked like on the inside. It's been a great gun over the past 15 years of my intermittent DIY auto repair uses. My only beef with it is the torque adjustment that's built into the reverse switch. I like having the reverse torque up high and the forward torque down low (breaking lug nuts free vs. installing them lightly before using a torque wrench), and when I adjust the setting for one direction, it seems to change the setting for the other direction as well.
Had my old girl OR for 17 years no oil or grease best guns ever Eric
Okay after 30 some odd years I think ill take my IR apart and clean it. Never even had the boot of to notice if there was a grease fitting. Thanks for the video tutorial
There is method to his madness. By captivating us with his videos, he also has a video record of the steps and placement of the parts - yes, Eric is far from crazy.
A little rusty in there from all that bad shop air.
hahaha
Rumor is customers that come in for free air get the bad stuff, while the paying customers get the good stuff.
MrGardman yeah the paying customers get nitrogen
Haha
Ive put together motors that are a similar fit, its nearly a line to line fit and you need to be very straight to get it to slide together..I use to play with the pneumatic die grinders the same way. My kinda mechanic.
great video Eric! i have one of those same impacts mine fell apart so was laughing at you trying to knock the rotor out! i do oil mine everyday i had no rust in mine! Cheers!
Gentlemeeeeeeeeen! Welcome back to the shop!
Reminds me when I took apart a windstar power steering pump with those fins, assuming astro affiliated with IR -didnt know that but I have both on my shelf..nice to see some fiddling without having to be frustrated, torque still 👌??
Good Video Eric, I have to say you definitely have an adventurous spirit. Air tools for me are a love hate thing, I love it when they are working and hate them when trying to fix one. All strange components for sure.
I don't use that Lucas air tool oil. I took a piece of scrap metal and polished it to shiny bare metal. In three different areas I placed one drop of Lucas air tool oil, one drop of Ingersol rand air tool oil and one drop of Top Ring air tool oil. I did not distribute the oil depending on the wicking action. I then set the metal in the weather for several months through the Canadian fall. On examination, the Ingersoll rand area which had expanded to an area about 4 inches in diamater was shiny. The Top Ring was a close second. The Lucas patch had a large accumulation of surface rust to the entire area.
And remember people. Any tool can be used as a hammer and most tools can be used as a pry bar! Lol great video. The fluid film on the JK worked great!
What a brilliant mind.... Can rebuild a " non serviceable" Kia diff coupling, and also his own air tools. Good job Eric!
IR 231. The god of the impacts
Repaired these for yr’s. You must heat the shell slightly to get it out. Freezer the cylinder and bits & heat up case to reassemble.
Thank you Dr. Eric , very enjoyable video.
Dude right after you said maybe they'll give me a job, you struggled so bad it was hilarious. Entertainment for sure man I love your content. SMA!
You forgot to throw a little oil on the cross bolt (direction change bolt/part/piece) to help free it's motion. Made a big difference when I did mine, don't shove grease in there, it'll find it's way in eventually but, some tool oil on either side while it's all apart will make you happy. 😀
The secret is to not remove the vane housing/motor in the first place. 😆 Just flush it with brake cleaner/solvent until it runs clear, spin it around, etc. until it's reasonably clean because, when you re-lube everything after disassembly and cleaning, you just shoot some grease in the back fitting with a mini grease gun, as that rear grease port's whole job is making sure that bearing gets greased, since you can't grease it from "the front" when you disassemble the tool for its routine maintenance (every 48hrs of run time), as you're doing here, sans beating the tool to death to remove a part that only comes out if that bearing goes bad, which only happens if you don't grease it regularly through that rear grease port. 😆
The way that part comes out is with a special puller that reaches in, like a bearing puller, hooks under the vane housing and you pull straight out. There's a small slide hammer type tool for little jobs like that. Finding one is another matter. 😀
Nice. Interesting how they work. You improvise very well, lol. Would have been nice to see you try it out. Just hope the new piece holds up like the old one. Thanks for sharing.
I own pretty much the same gun but from Mac tools. This thing is awesome! Never let me down
Ahhh yes the Mac 434C or M were great guns!
Excellent video this is something we really need it goes along with working on cars you must have a great tool in working order to do the job correctly. Thanks for the great videos...
Those plastic parts are called Vanes. Just like a air/vacuum pump. usually made out of carbon and expensive, they wear kind of like brushes on a motor. But that is for pumps, I'm not sure about an air motor. cool video, never took one of my impacts apart.
So does the IR earn a "skookum as frig" rating? Astro sure does for giving you a new anvil!
MrGordozzzz or an AvE subscriber
My favourite mechanics tip... The tool in the hand is the tool for the job.
I enjoyed that even though I have only ever reconditioned nail guns.
That's exactly how I fix or service anything. With a whole lotta pucker factor, regret, relief then victory!
Very cool I've done that on a few of the old IR231'S though one of them didn't work after and the other I just changed the anvil which was no problem. If you bought a Mac 3/8 impact for $100. that was a heck of a deal I've priced them out here and they're over $200
The exhaust ports in the bottom of the cylinder looked like they were offset to one side a bit, if so I’d imagine the cylinder is in fact directional as the timing of the exhaust ports would affect power in one direction or the other.
Yet again another great video brought to you from Eric and S.M.A. keep up the good work and Happy New year to you and your family.
