So my waterfall pump didnt run the last time I tried to turn it on...I dont really like running it as it just drops dirt into my pool. Anyway it wouldnt come on so I figured the capacitor was out.

I replaced the capacitor while working on my other pump motor and now the pump runs but it wouldnt prime...so I poured water into the where the basket was and the water just ran out from under the motor...so I am sure I needed a shaft seal.

Once I took the motor apart, the impeller was sitting off to the side...some of the internal screws had corroded apart. Where do I get these screws and what are they called? I am going to order a seal kit and these screws which hopefully solves my problem.

As far as the capacitor, the one I bought is the same voltage but the housing is bigger and will not fit into the cover.....Does anyone know where to get the right size housing or should I just buy a bigger shell to put on this motor?

Check if this one fits. This capacitor measures approximately 3" in height (including spade terminals) by 1 3/4" in diameter.

 
@ajw22 thanks

I think this one works..it says 3.5" total height..when i measure the old one its close to that...the other in the pic is over 4.25"

I think this what matches when I search the part number of the original and the part listed here on amazon gives that link above.


Do these look like the screws I need?

Amazon.com: Pentair 071660 18-8 Stainless Steel Socket Cap Set Screw 4-40 x 1-1/8: Garden & Outdoor 2 of these

Amazon.com : Pentair WhisperFlo Pump Impeller Screw 071652 : Swimming Pool And Spa Supplies : Garden & Outdoor one of these
 
I don't have any experience with the screws but they look correct. Let's see if @JamesW concurs.
