Hey, I just wanna say, these basic videos, and their commentary, are really valuable in a contemporary era where I fucking forgot half of that millwright class, but suddenly need to explain precision motor alignment to a suit in the morning. Thanks, gents!
Thanks! I hope this was a good resource. I have a lot of students that have to do this alignment and its always frustrating for them. It only gets easier with more experience. Just keep trying, you'll get it.
First thing you should do is establish length of rod to achieve distance needed to obtain measurements! Then confirm sag of chain jig!of Especially with those
@@rajeshkumar-ge2tu what do u mean? Edit. I think you mean it's going to shake so bad it'll shake off the rust.... I used to build turbofan airplane engines and pro mod drag racing engines. Dial indicators are not foreign to me. I got the alignment withing 0.004" in all directions. It's been running over a year now and the wind tunnel operator who runs it says it's quite than it's ever been. So thanks for the comment 👍
When doing an alignment, you should install the coupling element and turn both shafts together. This factors out any runout or surface deformities in the coupling hub.
Thats an interesting tip. I have to follow the text book and other resources for these videos. If you have a resource that suggests that, I'd love to get my hands on it.
Exactly. The angular alignment for example is based on an assumption that the flat surface the wiggler is resting on (pump coupling) is flat and perpendicular to the shaft. A way to not have to rotate both shafts would be to first rotate the coupling on the pump side and confirm the flat face is indeed flat, i.e. the wiggler stayed at the same position. Then you know that face is flat and perpendicular to the pump shaft and there's no need to rotate it. However, keep the tip of the wiggler in the same place on the flat surface for both tests.
There are many factors for alignment two shafts, firts, the Rod SAG compensated measurement, them both shafts must be coupling for eliminate any runout condition, don't forget it the soft foot, saludos desde Sinaloa, México.
Great video mate, but it would be helpful if you showed a bit more of the actual moving of the motor. I would have like to see how your dealt with moving the motor over toward you without ruining the angular adjustment while you were at it. I am talking about the 90 a d 270 degrees points here. I always struggled with that, I would get the angular adjustment correct and go to adjust the side to side and ruin my angular adjustment while I was doing that. Very frustrating. G'day from South Australia by the way.
Thanks! I'm glad this helped you. I plan to re do this video with better cameras and more explanation....and better acting haha. Thanks for the comment and the suggestion
Never indicate on a painted surface... get your chain under control ..... theres a reason why that wiggler has a "ball " end... laying it on the side of the coupling isnt getting you a true reading regardless.....you should honestly pull your couplings and work off the shaft in this situation.... as its the shaft you are aligning... the coupling isnt as important as the shaft in this circumstance as its a flex coupling
You had 50 at 12:00 not 0 but other than that you have me totally confused... thanks for the refresher!You do realize that the long pointy end of the finger is the indicator?
I was thinking the same thing and on the second go around, he was still zeroing to the short end of the dial. But, I still appreciate the video and look forward to finding more of them as I continue down my Mechatronics training at Valencia College, Kissimmee, FL.
with the proper tools make easy but some employeers does not want to invest in it I work for canfor sawmill most of the bases are home made with torch and grinder if the bolts dont fit make bigger with the torch is annoying
not the way i do it. looks like it may be a woods size 6. .015 parallel, .070 angular max. you can align this with the right light, with a straight edge
It`s called the Millwrights & mechanics guide 5th edition. by Thomas Bieber Davis & Carl A. Nelson. Its a pretty good all round book and it`s one of the few books that actually has shaft alignment. I think you can pick up a cheap copy off amazon, good luck.
OMG you did the alignment turn it just the motor shaft, that's it's wrong,you need to turn bouth shaft from 0 till 180 and better two have 2 axial dial set up and 1 for radial...And also when you touch the shims it's good to do just in one side (left or right) and make other side like that on horizontally your motor remain in position without not moving..I hope you understand what i say...
If float of shaft is less then no need to 2 axial dials. It is mostly use when float of shaft is more and normal axial misalignment avoid for flexible coupling spacer .!! also no need to moving both shaft here
We have been having problems aligning our pumps in the boiler room & recently our manger purchase the same type of indicator but it has two dials , to chain vises, swivel joints, & variety of tubing to mount the indicator. Well, my question is , is it still possible to get proper alignment if I already had the coupling come together or do I need to start back over , & go through each steps as you instructed . Of course the manual tells you to do it one way but being a visual learner , I would prefer to do it your way.
Hello! I think I understand your question and yes you can leave the coupler together. I think if you read a few comments below mccoy 1968 tells me that`s what I should have done for a better alignment. I`ve worked with people who swear by leaving the coupler out and other people that swear by leaving it in. This video is based on the textbook we use and it says to leave it out. I`ve never used your style of alignment tool so I hope this helps! good luck with your alignment!
I go over soft foot and cleaning/ inspection in my step 3 video. But honestly, I would search it on youtube because there are tons of videos on soft foot. I think vibralign has a very good one if I remember right
Its`s called the Millwrights & mechanics guide 5th edition. by Thomas Bieber Davis & Carl A. Nelson. Its a pretty good all round book and its one of the few books that actually has shaft alignment. I think you can pick up a cheap copy off amazon, good luck.
In short, yes this is very important but that might not answer your question. Below is link to a study on bearing life. about 3/4 of the way down the page is a chart showing that if a shaft is 20mil out it can have 50% decrease in life. This might be an extreme but the article has other levels of misalignment. www.efficientplantmag.com/1999/04/study-shows-shaft-misalignment-reduces-bearing-life/ hope this answers your question.
Tooele Tech Automation Manufacturing Technician thank you! That was very helpful. Is there any information on how to couple small external gear pumps with motors? Small as in ~.5gpm

The reason they sent 2 dial incisors is to use reverse dial method a reading value of 0 in the horizontal plane is almost never the correct final result you need to alow for themral growth a simple rule of thumb .00083 per inch at 100 degrees of temp rise all the people i have taught Lazer alignment to all benefit from learning rim and face dial indicator first.that is the method you showing on your video
I have been a millwright for a number of years and I haven’t used this method in a long time. With the advancements in laser alignment over the last 5 to 10 years why would anyone use this method?
I personally only know of a few places still doing this method but it is on a few pre-employment tests and I believe it is on the NCCER test for millwrights (Don`t quote me on that I`ve never taken the test). I think it also helps student visuals types of alignment but yes most of our curriculum is centered around laser alignment. Hope this helps you!
Tom Kane the vast majority of companies can afford laser alignment tools. As close to perfect as they do the job companies can’t afford to not have them. Also I’m not knocking this method at all. Just noting that laser alignment is so much better.
I'm a construction millwright aswell I recently worked on a project installing a gas turbine.The contractor supplied us with inside micrometers and dials for all alignments. It's still a viable method
when "shimming" your motor whether adding or subtracting NEVER loosen all 4 bolts at same time.. good way to lose your work... do 1 side at a time.. if you dont you will be chasing your alignment alot of times...

VIBRALIGN will show you that you NEED to tape it or put the coupling first
This is correct.
I was wondering the same thing I always do it with the coupling installed

Good information thank you. However the longer side of dial indicator is used to read zero or any other number.
You always set the plunger to half its travel range, so he is calling the 50thou mark on the dial 0
هل يممكنني الحصول على هذا الكتاب؟
why not use the long needle for your zeroing on the dial indicator
Thank you for this video
4th and final step, just don't forget. Good luck.
Great video - You mention book - where can I get a copy?
Both shafts need to turned as one unit (at the same time) and your reading the dial with the Wrong end of the needle!
Also where can i purchase that alignment tool you specifically have in your video?
Good stuff man 😎
Thank you!

The face of the mating surface of the 2 part hub would have been a much better surface for your angular reading!
What starrett set is this? Where was it purchased from? What is the range needed?
Up and down is called vertical and side to side is called horizontal sir
You had 50 at 12:00 not 0 but other than that you have me totally confused... thanks for the refresher!You do realize that the long pointy end of the finger is the indicator?

👍thank u sir
Please name the book u used
thanks sir
You can place both indicators at once with a little maneuvering! You must do a solid pre alignment!
If everyone comments it can be 1001 ideas how to do alignment
Do you have a publisher or your own manual? Great vid
We used the millwrights handbook for this
Thank you
No problem!
What is the name of that book,I need it
BEFORE YOU ALIGN THE HORIZONTAL MAKE ITS SURE ALSO ALIGN THE VERTICAL
Vertical always first
What book did you use?
not the way i do it. looks like it may be a woods size 6. .015 parallel, .070 angular max. you can align this with the right light, with a straight edge
how did you do the horizontal move, without fucking up the horizontal angular alignment?
Hi, Do you share me about double reverse alignment formular?
Great video. Unless these are stainless steel shafts, could you just use a mag base to hold your dial indicator?
I wouldn't because of rigidity. I am not sure of a scenario when a magnet base would be better.
What book are you referring to in the beginning? And can I purchase it?

Lose the wiggler with that kind of gap!
Is it important to be that accurate? What happens if youre are off by hundreths of a mm?
In short, yes this is very important but that might not answer your question.
