Electric motor bearing replacement

How to disassemble an electric motor to check and replace the bearings.
Note: the dimension at 14:32 should read 1.1816 inches not 0.1816 inches.

    Good except it's actually helpful to see you remove the first bearing rather than cut away during footage of the "heavy lifting." It's honestly really great to get a sense what physical stress is needed and what, if any, challenges there can be with realignment etc.

    Very impressive presentation. One thing that I do when installing bearings is to always have the shaft vertical, neverseeze or oil the shaft and always have the proper bearing drive device and hammer ready in case the bearing doesn't just drop in place. To prevent metal to metal locking, finish install while hot.

I was also looking for the comments and Is hard to believe that someone is here to comment about very accurate details, the professional guys don't need to watch KZread video to replace the bearings so is pointless anyway ! This videos are made for the people that need a basic way way to fix there problems not to learn a job! Anyway compliments

    Very impressive indeed. I had a hard time figuring out how theyd fit the bearings on a motor I got. Using a special Bearing remover . Afterward a tight fit, even heating up the bearing to make the hole bigger. its amazing. I am working on a shaft here and I was all wrong, I was going to use a threaded axel and fasten the bearings with nuts. Im going tight fit from now on !

    I think there are better ways of describing one of the sides of a motor. Most professionals I have spoken with about motors refer to the inboard or outboard side. Inboard refers to the shaft/ coupling side. If I had to say which side is the "front", I think it would be the shaft side, but that is my opinion only.

    This video is full of mistakes!1. The only times bearing orientation matters is when the two sides have dissimilar shields or one side is open, or when the bearing has a flange or an offset. 2. The diameter of that shaft is .1816?? Not likely. 3. Modern bearings are metric sizes.4. You NEVER drive a bearing on a shaft with a tool that is in contact with the outer race. That bearing is ruined!You're making other millwrights (as I am) look bad with dumb crap like this-

    Sorry you feel so negatively about this video. 1.To respond to your concerns, I mention the orientation of the bearing in this case to make the code easy to read if the bearing needs to be replaced. A deep groove ball bearing has no correct orientation as you said. 2. Yes I did make a mistake on the dimension of the bearing/ shaft. It should read 1.1816". I will make a note of that in the description. 3. Most bearings are produced to metric sizes as you said. The SKF charts I used to check the fit of the bearing give measurements in inches and millimeters and being that I am in Canada, we uses both systems of measurements. The tools I used were all in inches so that is the dimensions I used. 4. The final point about the tool I used to install the bearing. The tool is manufactured by SKF (as seen at 19:34) which is one of the leading bearing manufacturers of precision bearings and the instructions say to use the tool as I have done. You are also correct that driving a bearing onto a shaft by the outer ring only, when being installed onto a shaft, would cause brinelling and damage the bearing. However, the tool I used has a feature that contacts both inner and outer rings at the same time. In this application it would be acceptable to press or drive the bearing on by pushing on the inner ring only, but in other cases where the bearing is being installed into a housing and onto a shaft at the same time it would be unacceptable to press on the inner ring only and would need to be pressed on by contacting both rings at the same time. You can clearly see the shape of the tool I used at 19:34 and that it does contact both rings at the same time. For the future, please be constructive with your comments instead of destructive and i would be happy to make corrections where needed.
