I’m not a Millwright by any stretch of the imagination but sometimes I do that kind of work.
I have changed out 300 HP electric motors that run on 480 volts and weighed over 1600 pounds. The best part is that they were inside of a 3 foot across pipe 4 foot off the ground.
I couldn’t find an exact match but this is close enough. It’s inside that bell in the front there.

Loads of fun, trust me.
Of course I’ve swapped big electric motors on pumps and other things too.
Things like this,

The thing is, the alignment of the pump and motor shafts is a critical thing.
If they are not close to perfect, it will vibrate and very quickly eat up the coupler or bearings on the shafts.
I’m talking thousands of an inch .
They have a laser alignment tool where I work but I have had to do it the hard way too.
That’s why this little skit of Millwright Humor hits for me.
