So my 2017 vintage 2.7hp E Pump has started making what sounds like a dry bearing noise from the motor. I'll link to a YouTube of the noise.
Do y'all agree it sounds like a bearing? Are they available? Schematics I'm looking at on Inyopools don't list them.
Also appears of course the motor on my pump isn't even available any more.
 
Sounds like bearings to me but I still like to eliminate any other possibilities that might be easier to fix.

It seems to get louder in the back of the motor. You can take off the shroud and see if there is any debris that might be causing interference.

Bearings can be replaced at a motor shop or if you have the skill set, you can do it yourself. There are many videos on YT that can show you how to do that.

Have you seen any water below the pump right where the motor attaches to the pump body? The video doesn't seem to show evidence of a leaking shaft seal. Motor bearings are sealed and it usually takes a leaking seal to wash the lubrication from them. If not, likely not a damaged bearing but a cold one that has shrunk a bit and the tolerances are a little loose.

I have never seen water leaking from the pump/motor connection. The bearing noise is coming from the rear bearing anyway.
Inyo Pools doesn't have a listing for bearings for this motor.
I have reached out to both Centry and Jandy for at least bearing specs or part numbers. Am not holding my breath since apparently this motor isn't even available any more!
Why sell someone a motor when you can make them buy a whole new pump!!

Sounds more like interference in the fan than bearing noise. Sometimes the fan shroud gets bumped/kicked and is now lightly touching the fan. While I'm sure it has happened, in 34+ years I have only seen one rear motor bearing go out, and that was on a pump with a severe seal leak that was flooding the entire motor.
Those motors were the Century V-Green 2.7SQU but with slightly different software to work directly with a Jandy control.

So yesterday I removed the rear shroud. No evidence of the fan rubbing on the shroud or any debris in there. I took new videos of pump running at the same speed as before and with/without shroud on. The noise is very much less loud as the day before. Yesterday was also 20+ degrees warmer than on Wednesday. Colder again today so will see if it is loud again today.
So yes, does seem that my luck, it is the rear bearing on its way out.

Generally, we do not recommend replacing the bearings yourself in a variable-speed motor. The magnets in them are pretty strong and you can damage the motor (or yourself) when replacing the bearings without a jig to safely hold everything. A local motor repair shop should be able to take care of that for you.
