Replacing a motor on a pump, and getting the correct size for your pool?

According to the label on the current pump, it's a USQ1102 equivalent, with a SF of 1.25.

Thanks for all the help! I think I'm going to get or order the SQS1072 after checking with my local pool warehouse.

Am I understanding this right... could this be used to program when the pump is on while also putting a timer on when the pump is switched to a certain speed? Would the main on/off timer feed the switch that determines when the pump is on full speed? That's the sort of thing I'd find handy to have, with manual overrides (if possible.)

Never mind the previous post. I found the wiring diagram on how it works.

Thanks for the help! I ordered up the SQS1072R pump and the T10604 yesterday, and they should arrive tomorrow evening. Since everything was down, I went ahead and replaced the faulty pressure gauge on the filter too.

I just hope I can piece everything back together with the motor when it arrives. Any videos/tips on putting a motor back together? Anything that I need to be aware of?

Fired it up for about a half hour late tonight. Found I had a multiport valve leak and still haven't finished rebuilding the filter yet, so I'm leaving it off until tomorrow when I'll have time to monitor it to make sure everything is working.

Been running for a while, and it's fairly hot to the touch, and I'm only seeing 12 psi at the filter. However, the skimmer is sucking things in at a rate like I've never seen before, so I guess the suction seems to be working well there. Should I be worried about the pump being too hot, or is that pretty normal?

Pump motors can get pretty hot but unless it is shutting off, it is probably ok. One reason to run on low most of time.

After being down for a week, I wanted to get it going. I have an Intermatic T10604R timer to control it, but it's not hooked up yet. Probably should have the electrical ready for it by tomorrow (there was NO timer control whatsoever prior to this whole ordeal.)

I'll probably have it on low most of the time, shutting it down for about 6-10 hours a day at first, until I figure out how much I actually need to run it to keep it clean. Our yard has arbor vitae trees as a privacy fence around our whole yard, so the debris from them lands in the pool all the time. Probably can't shut the pump off completely for very long.

...and the SQS1072 is smoking. Could this still be too large of a pump, or not large enough? The pump is having problems priming, and is overheating right about where it's getting close to being fully primed. Im at a loss as to what's going on...

The motor is the same size as the old motor so should be fine.

But make sure everything was installed properly (impeller ring, diffuser, seal, etc). Any misalignment can cause overloading in the motor. Otherwise, you might just have a bad motor. I can happen sometimes.
