Pentair LA MS05 booster pump bearing question

[Talahasseemark]

Hi Guys,
I have a pentair booster running a Polaris in a 28 ft fiberglass pool. This was a new build <2 years ago.....
Suddenly, the booster motor became very loud. It still drives the Polaris easily.
I’m fairly handy and think I can replace the bearings if that is what it ends up being...
However, I’m struggling to find the bearing and seal part numbers. Who can I contact to get the part numbers and parts.
I will try to attach a video of the sounds and the motor ID plate.
Any advice appreciated.
Mark

Try InyoPools. Though they may just have new motors and seal kits. Otherwise a motor shop should have the parts.

I just had mine quit about a month ago. It was three years old. I couldn't seem to find the parts either. I looked for the, "fan kit" ( #P ZBR43810 FAN KIT )locally with no luck. I pulled the fan grill off and noted the winding was hard to turn. So I just replaced the pump. You can actually stick a regular screw driver in and try and turn the shaft to see how stiff it is.

Pentair gave me the seal part number , but said they don’t make the motor (even though it carrier their decal) so couldn’t give me the bearing size or part number.
Advice?

Most motors are AO Smith or Century.

I suppose I can pull the bearings and check the sizes?
