Milwaukee Tools New 3/8 Stubby Impact Wrench – How to Best Use in an Automotive Repair Shop


well everybody I’m Brian Esther from how to automotive and today I’m excited to do a review on the new Milwaukee Tools stubby impacts that just came out so they sent me to the new tool symposium a couple months ago and I got to see these these were the highlight of the show by far the most buzz on it so this particular model is the 3/8 model in this video I’m gonna do the demonstration on the 3/8 in other future videos I’ll do the 1/2 inch in the quarter inch drive but for this one what I’m gonna do is I’m gonna do a major repair on this vehicle right we’re here in front of me so I’m gonna do a spark plugs or Radiator timing belt valve covers cam seals crank seals and I’m gonna try this use this solely to remove as many fasteners as I possibly can to show you guys what this tool can do how this tool could be a beneficial for you and also show you some of the limitations that it may run across as we do this major job so stay tuned for that so before we put this tool to work I thought I’d do a little unboxing show you what you get for your money go through some of the specs on it so you can get these in bear tool or kit form this is the kit form the part number is twenty five fifty four slash twenty two and once you get it out of the box it comes in this embroider carrying bag inside is going to be the bear tool a two amp hour battery a four amp hour battery and a charger so when operating the tool it has four separate modes that you can put it in just by pushing the button on top the first setting is power level one which is twelve hundred rpms power level number two it’s 1800 rpms and power level number three is twenty seven hundred rpms and the fourth level on the tool is the auto stop feature meaning that you can run a faster in and soon as it hits ten pounds it automatically stops so now I’m going to show you those features in action we’re gonna take this little stubby impact and we’re gonna disassemble this this large job that are doing here like I said I’m doing a spark plugs timing belt water pump cam seal cranks seal thermostat housing valve cover gaskets so I have to pull off the intake manifold so on the tool I have a two hour amp battery that’s fully charged and we’re gonna start disassembling this engine so one of my first task was to remove the right front wheel on this vehicle so I went ahead and used it to take off the lug nut it had no problem the first thing I noticed it has super smooth feeling there was very little vibration in my hands and it took the lug nuts off with no problem so now I’m taking off some inner shield here I got a ten millimeter socket on here and it took these off off obviously no problem now we’re back up top and we’re gonna remove the support brackets here for the radiator this is a twelve millimeter sockets that I’m using that’s underneath here I was removing some of the skid plates and plastic shields so I made quick work of all those type of tasks I got the radiator out in no time I talked it took the air cleaner assembly out with no problem now I’m here I’m using it on the throttle body I’m using to take off these twelve millimeter bolts on fasteners on the throttle body and as you can see the compact size allows me to get in there now I would classify this as a light to medium duty tool which makes it perfect for disassembling engines so now I’m taking off some 14 millimeter nuts they’re holding the intake manifold on I got a little extension on it and it took the 14 millimeter nuts off with no problem but the two Center nuts on this or an 8 millimeter allen sockets with the extension and when I went to go take those off with the Allen socket it it didn’t want to take it off with the with the extension so it struggled a little bit so what I did was I took the extension off and then once I took the extension off I tried it again and it took the fasteners off so using extensions with any impact tool will reduce or Rob the amount of torque that it can produce so every now and then you’re gonna come across a fastener if you need to crack free by hand first and then use the tool to finish removing the bolt Here I am using it to remove the valve cover bolts here and they had no problem removing those pretty much any 10 and 12 millimeter fasteners so you can run across this kind of rip those right out with no problem you get some of the bigger bolts and you may have to loosen it up a little bit with a hand ratchet first this is a 12-volt tool it does have 250 foot pounds of breakaway torque and also 250 foot pounds of tightening torque on it which is a lot for our 12-volt tool so I just took out the ignition coil now I’m using it to remove the fasteners for the valve cover here and there’s about eight or nine bolts on this cover and you can see how fast it was to rip these bolts out so that’s the name of the game is speed and this tool is definitely going to help you make more time so in this clip here I’m using it to remove some motor mounts and it has a couple 12 millimeter bolts on it which they took out those with no problem but then when I switched over to the 14 millimeter socket to remove the 14 millimeter ones it gave me a little bit of challenge on a couple of them but these are extremely long bolts some of these bolts are really long that this particular one was short but the the next two are long they’re about about a foot long and that excess these fasteners twist they lose a lot of their torque em so it took a little bit of a hammering on it but it eventually did knocking bolts loose so as you can see this little stubby tool is helping me make quick work of this pretty large job here I’m getting it tore down pretty fast and this next clip is where it really shines though so I’m taking it to loosen up this belt on this alternator here and I’m sticking it down in this very confined area to loosen up the fastener and it it was easily fit in there and it allowed me to get in there and loosen that up now back underneath the car I’m in a confined area again and I’m using it to loosen up the fastener for the power steering belt here and having that small compact size allowed me to get in there now I’m trying to use it to take off the crank pulley on it and I was hammering on it good I even reversed it and tried to go back the other way and and it would not take the crank pulley bolt off to be fair I had to use the high torque on that to get that bolt off now I’m using it with a crank pulley puller to pull the crank pulley off and it takes quite a bit of torque to pull these off so I’m using it in forward mode and it’s pulled the crank pulley off with no problem now I’m going to switch it to mode four and demonstrate what that does for you so mode four as you screw a fastener in as soon as he hits ten foot-pounds it stops torquing and stops the tool so I’m running this crank bolt back in because I wanted to use it to rotate the engine but I don’t want to tighten it up too tight so as you can see it ran in and stopped all by itself that was the tool doing that now I was able to put a hand ratchet on this and rotate this engine around so I can line up the timing marks on it so if I had ran that bolt in and slammed it in there it could damage the end of the crank so you don’t want to do that so that’s where that mode comes in handy so here I’m using it to try to remove the cam bolts on this particular car and I was hammering on this and it just did not want to come off so the head of this fault was 17 millimeter it probably would have taken the mid torque or maybe even the high torque if you could fit it in there to get that fastener loose so after hammering on it for quite a while I had to switch over to a half inch ratchet and a and a pretty large wrench to crack this free eye it took quite a bit of effort to crack that bolt free so here I’m using it to remove the timing belt tensioner I’m using a quite a long extension here it’s about 18 inches long if a 12 millimeter socket and sliding it up from underneath the the frame here to get to the fasteners and with these long extensions it could Rob a lot of torque but it took these bolts out pretty much with no problem so after taking the timing belt tensioner off and I switched over and cooked off the timing belt roller there the cam pulleys and it had no problem removing these fasteners either so my first impressions of the tool are very good I thoroughly enjoyed using it it did everything I asked for it to do and everything that it couldn’t do it was because those fasteners were extremely tight or on there for a really long time so as you can see it helped me tear this engine down in no time flat I made really good time with using this tool now I’m gonna go back together and I’m gonna use power mode number four here to run these fasteners down on this valve cover here and as you can see I’m just running them down until they hits at ten pound mark which is pretty close to the actual speck of torque on these valve covers so it ran down until I hit ten foot pounds and stopped on every one of the fasteners so it just ran the fasteners down stop right at ten foot-pounds then I went back over all these fasteners with a with a ratchet and torque them down by hand so that’s pretty common when reassembling engines you run them down till they’re snug and then you go back over the bolts with a or if I torque wrench to torque them down to their final torque so having that mode four on the stubby impact is a pretty cool feature that you’ll probably use that a lot when you’re reassembling engines here I’m using that mode four to tighten down the timing belt tensioner pulley here so you definitely want to talk that suspect so you just want to run it into it snug and you go back over it and torque it down and here I’m using the mode four to run these coil pack bolts in you don’t want to smash those in you could damage the coil pack so mode four is a super handy handy convenient thing to have especially working them with automotive use it also has a variable trigger on it that allows you to use that trigger to fine-tune the torque as you’re going over these particular fasteners tightening them down here I’m using it in power mode 3 which is the most powerful mode to tighten down these motor mount fasteners and make quick work of that and got these nice and tight the longer you hammer on the trigger the more torque it gets so you have to hammer on it quite a while for it to get to that 2,250 foot-pounds of torque so using this stubby impact took this engine apart and put it back together with no problems at all I even got to try it out on some brake jobs and it made quick work of all these fasteners I had no problems doing a brake job on it I had no problems removing wheels and I did this all on one battery card so this all this work you see done is still the original battery charge when I was done doing this particular this bridge job here after I was finished with this I still had two bars left on the on the fuel gauge I’m bright acid from house autumn up and I like to thank you guys for watching my videos and if you’re interested in helping me how to automotive YouTube channel out the best way you can do that is by purchasing t-shirts stickers and coffee mugs I’ll leave a link for that in the description of the video so if you like this tool I will leave links for it in the description of the video that way you can pick it up for yourself i’m brian desta from how to automotive i like to thank you guys for watching my videos encourage you to subscribe invite you to head over to the how to automotive comm website for more valuable videos like this thank you
