Pool pump motor leaking

[coolinthepool]

Hi, all—I installed a new pool pump motor this past fall and it’s been working great. Today I went out and noticed the water had dropped significantly. Upon inspecting the equipment, sure enough, the motor housing was dumping water out. I’ve refilled the pool.
I’ve taken the motor off of the housing and inspected the o ring and ensure the impeller is spinning. Those seem to be fine. Honestly, I’m not sure what it is. The impeller/diffuser weren’t replaced when I replaced the motor, so it could be those. And if I replace those, I may as well replace al of the o-rings again. Thoughts?

Here’s the model:

Probably a bad seal. What is the pump model number?

That’d be great if I can find out which seal it is. Model is c48k2pa105c5

That's the motor model number, we need the pump model number.

Found it! Impeller tension spring is broken.

And sorry, to answer the question you actually asked, pump model number is usq1102

You're reading the motor label. That's not going to help. We need the information from the pump. What numbers can you see anywhere?

What is the part number that is visible in the picture?

I appreciate your help, I posted a picture of the problem. The shaft seal spring was broken. I’ve already ordered the replacement. Thanks again!

I finally got this fixed. The impeller ended up being broken as well—a hairline crack that wasn’t immediately apparent. I’m a pro at disassembling this thing now, btw.
