Hayward pool pump capacitor question

[TexasBR]

Hello Friends,
I am looking for guidance about the correct capacitor for a Hayward SP3215X20 TriStar Single-speed Max Rated 2 HP Pool Pump.
When I opened up the "bump" on top of the motor, I found a 30uF 440VAC capacitor (made by Genteq).

However, the Hayward website (Capacitor, 35Uf, 440V | Hayward Residential and Commercial Pool Products) lists a 35uF, 440V capacitor (Item #SPX3200CAP4). Has the previous owner installed an incorrect/suboptimal capacitor?
Here is a screenshot.

Confirm that the original motor is still on the pump. If so then you should use the proper capacitor.

Post a pic of the motor data plate.

The correct capacitor should be listed on the motor data plate. Also, you don’t have to buy the capacitor through Hayward. You can get the same size from any HVAC supply store or Amazon.

Thank you so very much Gentlemen. Here is a picture of the motor plate.
I did not see any mention of the capacitor on it. I wish manufacturers were clear about stating routine maintenance items like capacitors.

Thank you Allen. By proper, did you mean 35UF or 30UF?
Much appreciated.

I have the exact same 2 HP motor with the exact same part number as yours. My motor has a 30X440 capacitor. See pics of mine. Ignore the +5 UF on the cap as I replaced my cap with a dual capacitor I had on my service truck and I’m not using the 5 UF side (I’m an HVAC service tech). I am the original owner of my pool and I replaced my cap with the exact size.

Thank you so very much johnw. I will order the 30uF 440 volt capacitor.
Best Wishes.

I agree you should use a 30 uf capacitor.

Gentlemen, When I opened up the "capacitor hump" on the motor, I found a white plastic sheet-like part, and some foam, in addition to the capacitor itself. I am curious about the purpose of these items, and the correct way to place them.
Thanks again for all your patience and generous help.

Show us a pic of what you found?

Foam is a filler to keep the capacitor from rattling. White plastic circular piece should be placed over the terminal end as an insulator to prevent arcing to the metal enclosure.

It's OK to use a capacitor with more capacity (higher microfarad / uf), but you don't want to go lower. Well, you also want to stay within 20% of the original - so 35uf is ok, but i wouldn't go to 40uf. Much of what i said here is for a run capacitor, you are likely looking at a start capacitor - in which case you can essentially throw out the 20% rule and put in what fits. (do not go lower on the voltage)
