hey guys in this video we're gonna go over the precision alignment step I believe it's step number four depending on what type of equipment you are working with that will depend on how this step goes down how it works in this class is I'm gonna teach dial indicator right now and then later I'm gonna have another video on laser alignment they're interchangeable this step is the one that can be done multiple different ways depending on the type of equipment you own or your company owns I should say dial indicator is just kind of a kind of a basic old-school way laser alignment is kind of a new way so like I said in this video we're gonna go over dial indicator and we're gonna start with setting it up on the machine notice that I have I've already completed my rough alignment my soft foot check it's all tightened down and I'm gonna go over how to install the dial indicator on to the motor shaft I believe and then we'll just take it from there I'm not kidding the hardest part of this whole process is getting the dial indicator installed on the shafts in the correct way but we're gonna go over in this video that way there's no confusion alright guys first thing I want to point out is I'm gonna have my book out the whole time I'm gonna start on well because we finished all the rough alignment and things like that we're going to start on like 397 this has already should have been done in your required reading you should have already read over this but we're gonna go over it as we're putting this thing together so it's always good to have your book out with you so first thing we're going to do is we're going to need to set up the wiggler to do a face face indicator or face or you can also do this back face over here depending on what you like the most I personally tend to go off the back just because the this style of coupler is pretty rough so the tools you're going to need and I'm going to install them as we go along here the first tool is just our chain vise or chain clamp we call it and we're going to put it on to the motor side sometimes CIO to spin around sometimes you can prop up the back end of the fan which I'll try to get a picture of to show you next we're going to start installing all of our parts for our final indicator the first thing I'm going to do is depending on the look of what we're working on we're gonna grab this shorter bar I think we're gonna give this one a shot in here sometimes necessary to just put a little bit of a cinch down on it nothing crazy just want to make sure it's locked in there pretty good next we're going to go ahead and install the actual wiggler so this is if you wanted to read off in the face we could you do it this way all right so hopefully you guys can see how this is supposed to be looking right now so for this if we were gonna use it in this location we're gonna start in the zero or the top topmost area of the coupling right about here and we're going to go all the way down to the bottom end so this would be considered zero and this would be considered 180 and we're going to check we're gonna start here at the top see what the reading is go to the bottom and see what our reading is then okay okay so I apologize for the shaky miss of the camera here but I want to show you that I have the dial indicator set to zero and I'm gonna rotate it around and I'm gonna show you that see the dolls moving see that and then it's gonna end around 15,000 from zero so I'm gonna talk about that for a second so this is where it gets kind of tricky for people because our dial indicator actually showed a negative down on the bottom end when it was when we started at zero up here so what is that telling us that's telling us that the actual dial indicator went out instead of getting pushed in so let's go ahead and zoom in on that dial indicator so like I said this actually the plunger here down here on the bottom of you can see my pointing actually came out instead of getting pushed in so what is that telling us that's telling us that off this wiggler here that the wiggler the top end went in while the bottom one and a bottom end went out so that's telling us that our coupler is actually slightly further out on the bottom side than the top side so let's go take a look at that so to fix that we're gonna need to bring the back end of that that motor out so I was actually wrong that the rear feet need to go down when I said they need to go up so in this video you're gonna see me put shims under there realize that I was wrong and and decide to but go back to where it was check it again drop it down big thing I wanted to point out is just rechecking a tree doing a tree looking at it because like I said it's very simple - or very easy I guess to get confused like I did so after repeated attempts that I'm too embarrassed to actually show you I went ahead and decided that it must have been the you know dial indicator so I went ahead and started indicating off the back side and this is the process that I'm doing right now I'm just gonna I'm setting up with the longer rod and I'm just going to use the backside of it to indicate [Applause] and I hope that you can see how I've got this thing set up if not I'll try to take some pictures of it have it posted here so that way you guys can see it on canvas let me go ahead and I'll even get some close-ups of it right now so all I really did is I have the indicator down here and then I had to flip around the dial indicator so that it was actually just indicating off of this space rather than this interface if you go wherever you can find the flat spot you can pretty much indicate off of so there's nothing wrong with doing in here you could I could have won I could have pulled this coupling face off and indicated on the scene or on the edge of the of this piece right here or I could have even flipped it around on the back of this one if necessary that would not have been ideal just because of the space and because when we have to put back together got some problems okay so I'm gonna go ahead and show you how the dial indicator looks now right here I got it at the top you can see that it's zeroed and we're going to slowly rotate it around here oops and you can see that it's still at zero sorry if I didn't say this before but the purpose of the purpose of setting up our dial indicator this way is to get the motor in there front to back we're trying to make sure it doesn't have any angular misalignment at this point try to make sure it's perfectly level with that pump alright so we're gonna go ahead and move on to the next step and get that set up for you and I'm specially how that is okay so I'm gonna pull this off and I'm going to install the dial indicator a little bit different this time and it's gonna gonna it's gonna ride along this outer edge and what this is going to tell us is if we have parallel misalignment and we're going to start in I believe at the zero point and go to the bottom so then we'll know again if we need to add any shims we're getting all that done before we start working on our side to side all right see how much easier that one is to to look at or to set up I guess so again we're going to start zero up here we're gonna go ahead and I'm gonna remove my folder there oops a little bit faster than I wanted to go and then we're going to drop it down and we wanna take a look now we don't care what the measurement reads over here we only care about zero here I'm gonna try to make this one zero down here too I'm not gonna use I'm not gonna show you this with the camera because typically you have to use a a mirror of some sort to look at that okay all right so I I if you can see I use my phone instead of a mirror I just flipped it on so that the camera was looking up here and from from here I started I got 0 here and I'm gonna go ahead and I'm gonna move it down and I have about 11,000 to 11th ow we'll go ahead and say it's just 10 so that means this pump needs to move all right depending on if it's a positive number or negative numbers is gonna tell us a lot so let's go ahead and figure out if it's a positive number negative so it looks like looks like a negative 10,000 so a negative 10,000 that we need to it would mean if it's negative it would mean that we need to move this up okay now this is the tricky thing when you're working on a round object you don't take off we don't move it the full amount we move it half of them out so we're going to put a 5,000 shim under all four of these feet to bring it up to the correct alignment and then we're going to see what it looks like we're going to recheck it at that point see what it looks like okay so I added my 5,000 Shem now I'm gonna recheck this so when I start at the top Reesie row it right there already come down we're going to see all right so let's take me about 30 minutes of just swapping shims out put them in changing the back rechecking it over and over again and now I'm within about a thousandth of an inch so I'm going to go ahead and move on to the next step the lucky thing for us is now with those first two steps what they did is we figured out our whole shim pack so everything else we're going to do from this point on is all side-to-side angular or side to side parallel misalignment so we've kind of we've kind of completed the hard part now let me go a lot faster the cool thing is all of the setup for the dial indicator is exactly the same so this we're going on to the third measurement which will be we're going to be checking for angular side-to-side misalignment and we're going to set up the the dial indicator as if we were at the very beginning where we did angularity for the pump in the horizontal position so let me go ahead and I'm going to set that up for you and then we'll go over [Applause] so like I said we're going to set it up in the exact same way hopefully you can see this I'm going to zoom in right now all we've done is we've set a dial indicator in the exact same way we did in the first step so now I'm going to do it for this time we're going to do it from the ninety position our 90 degrees to 270 so we're going to go over that okay so my 90 is over here so I'm going to go ahead and take the move my zip tie there we go ahead and zero it out and then I'm going to go ahead and I'm gonna move over and it looks like I've got about 10,000 stare so what I would do is we can kind of do a little bit of this it's not quite as easy going in this direction but you can loosen up the bolts and we can try tapping it over this is a very fine adjustments that we need to be doing so I'm not loosening these bolts a lot I'm just doing like a little half turn maybe 3/4 of a turn [Music] what I did is I actually loosened my bolts a little bit not a lot of time and just kind of tapped it around while I was moving back and forth retighten it down then I actually did the reading again just seemed like there's a lot of movement this took me about 10 to 15 minutes just to do this step I'm gonna go ahead and we're gonna grab the camera and I'm going to quickly show you what the dial indicator looks like I'm about out right now and that's that's pretty dang good so I'm always shoot to be within 1000 by the end you're gonna be you're looking pretty good so we'll go ahead and do that really quick yeah so we're gonna start at zero you can see that even at the top well within 1015 1/2 pound so you can see that it's right now all of angular alignment should be removed from this home all right so now that I've checked my angular misalignment what I'm going to do is I'm going to take and set up the dial indicator just to set up for checking my parallel misalignment if you've noticed the steps break down you check for angular parallel angular parallel so first you're gonna do it in the top the up and down position and then you're doing the side-to-side all right so let me go ahead and I'm gonna set that up really quick we will continue on [Music] all right so now I got that set up I'll pull up my zip tie that I hold things down for I'm gonna go no I'm gonna go again from the 90 over to the the to 270 mark all right so looks like you're about 20,000 South so we can go ahead and put this over here and try to do the same thing I did before now with the parallel misalignment we need to bring the whole motor towards me pretty much so if you have a positive number yep we got a positive number so it's got to comfort me [Music] okay so that's a pretty quick step right there and I'm going to go ahead and we're going to show you the but I'm going to show you the dial indicator view here in a second but I got 0 I go up to here I'm still at 0 because now I've taken all the parallel misalignment and then all the way over the other side I'm still at 0 I'm gonna go ahead and show you that right now so as I was saying so I'm at 0 this is in the 90 position I'm gonna come up and this is in the zero position I'm looking about 1/2 pal and then I'm gonna try to show you this guy he's in the zero position too and this is at the 270 now because I have all three measurements I know that the fourth measurement would be correct all right so now that I've completed all of those those steps in order in correct order I now know that I'm perfectly aligned so all I need to do is put in the coupler and I'm done or I guess is before we put in the coupler I should actually go back and double-check all all of those measurements okay so I'm going to go ahead and do that really fast and then I'm going to install that coupler and we're all done with this project I got lucky when I went to reinstall this I was able to just slide the couplers back on the shaft and slip that little Center coupling back in there worked out great now I want to show you I want to point out one last thing for precision alignment here you want to make sure that your coupling is balanced by standby balance I mean that the key waves are a hundred and eighty degrees out from each other and you'll notice that I tighten down the one and then I go ahead and I spin it 180 degrees and tighten that other one down so just make sure you always do that and you'll be good to go and that concludes the fourth and final step the precision alignment wish the dial indicator make sure you can have your tools and should be good to go
