Hoping for a quick answer as I'm in the middle of this and it's too hot to do in the afternoon.

I'm replacing my booster pump motor. When putting the spring portion of the seal on, it compressed when I pressed it on and I'm not sure if that's the trouble. See pic.

But when I screw the impeller on, it doesn't turn freely and makes a grinding noise at part of the revolution. The impeller has some wear as shown in the other pic.

How to get the spring uncompressed is my first question? And do I need a new impeller is my next?

Thank you, good people!

There are two different impellers depending on the serial number.

There is an older model PB4-60 and a newer model PB4-60. The newer model (PB4-60s after serial number PB120111001) uses part number R0445500 (Polaris Mechanical Seal) whereas the older model (PB4-60s prior to serial number M120111001) use part number P55 (Polaris Seal, Stainless Steel Cup and Spring).

For the older model, the stainless steel cup goes in the bracket/seal plate with the black graphite part pointing out. The rubber part goes in the impeller with the ceramic sticking out. A 1" PVC coupling fits perfectly over the cup to help insert the stainless cup into the bracket/seal plate.

For the newer model, the rubber part goes in the backplate/sealplate/bracket with the ceramic sticking out, while the spring part goes on the impeller with the black graphite part sticking out.

You can quickly tell by looking at the bracket. That's the part that bolts onto the motor.
From the side, if you see the motor shaft through a single large hole in the bracket (one on each side), that's the old style.
The new style has 4 wavy slots in each side.
It's profoundly aggravating whenever there's a design change but the same model name/model number is continued.
The PB4-60 is probably the worst offender, in that it is one of the most common pumps out there.

@JamesW thank you. I found that but PS-4231 on some sites pulled up the 5/8" and then the whole 13/16" completely confused me.

@Mayorb thank you as well!

Turns out it was crappy seals from Amazon. Sigh. They were the only ones who could get me the part quickly and I was desperate. But then I found a genuine Polaris one at Leslie's (even though their website said it wasn't in stock!!) and it worked like a charm.

I had two different ones from Amazon and one fell apart when I was installing it (the spring side) and the other compressed and wouldn't uncompress at all.

The Polaris one went in so easily and perfectly and appears to have solved my issue. (Fingers crossed I don't go back out to a drip!)

Thank you again. Lesson learned. Use real parts not crappy ones from amazon!!!
