SOURCE: Can I replace a 1 HP square flange pool pump motor that has a solenoid/capacitor on the outside of it with one that doesn't?

Yes. The one that doesn't have the capacitor on top has it inside.

2001 arctic spa is showing error code FLO

FLO is for not enough water flow
This is a filter issue or pump issue. Remove filters and see if it goes away. If it does get some new filters here: http://www.hottubworks.com/

If it does not go away call us and we will walk you through trouble shooting. Most likely a circ pump if not filters.

Hello, I am trying to replace the front bearing on

If you haven't got your answer yet, I can help you, but it seems very late to reply. I have a same model, I take apart it, I see 2 bearings, you probably need puller to get it out.

Where do you hook in the neutral wire (common) on 230 volt install

You do not...you only use three of the 4 wires if you have a neutral pulled out to the box. Both line wires go to the motor along with the ground, cap off the neutral.

My pump hums for a few minutes and then quits altogether.

This is a classic sign that it is miswired. Check to make sure wether you are using 110 or 220 wiring and then verify how the motor is wired. If this is an existing motor, you probably are getting moisture to the motor. Not a good thing. Replacing the pump shaft seal may do the trick, however you'll want to check the motor for any other obvious signs.

This is a Speck swimming pool 1.5kw pump I need to replace the motor stator bearings but don't know how to take the pump impeller off

This is the most popular pump frame. The motor will actually have a square flange as an integral part of the motor (not the pump) on the front of the motor with 4 holes (one hole in each corner of the flange). The pump body will be secured to this square flange with 4 bolts, which are outside the round barrel of the motor. Caution: Make certain the square flange is part of the motor; not the pump body. Many pumps are square and may appear to be part of the motor. Removing the motor from the pump will allow you to make certain how the pump is fastened to the motor. How the pump is fastened to the motor determines the basic type of frame.
Note: Also, some 48Y frame motors are actually thru-bolt style; therefore, check the mounting bolts to make certain they are not thru-bolt style as described below.
Not a square flange on your motor? If you do not see a square flange as described above for the square frame motor, then you have a pump body, which mounts to the motor with 4 bolts accessible inside the pump case. This non-square frame will be a thru-bolt style frame, 56J frame, or 56C frame. How to determine if you have a 56J or 56C frame: The pump body mounts to the face of the motor with 4 bolts just inside the circumference of the motor barrel. To see these mounting bolts, you must take apart the pump body and look inside the pump. The bolts will be fastened into the face of the motor with threaded holes. 56J frame: If your pump body mounts into the face of the motor as described in the previous paragraph, and the impeller is threaded onto the motor shaft, then you have a 56J frame. Additionally, the impeller may be secured with a small screw, which is threaded into the center of the motor shaft. If the outside of the shaft is not threaded, maybe you have a 56C frame. 56C frame: If your motor has a shaft with a key-way (small metal key slides into a groove machined along the length of the motor shaft), then it is a 56C frame. These are very rare in today's pumps. If your pump is 20 years old or older, it may have a keyed shaft (56C), but even then is unlikely. The keyed shaft may also have an internal tapped thread to help hold the impeller once it slides over the key-way. Thru-bolt style frame: The motor mounting bolts are the key with this style of motor. Like the name implies, if the pump fastens with nuts to the 4 bolts, which pass all the way thru the motor, then you have a thru-bolt frame. These extremely long bolts (8 inches or longer) will go through the motor. These motors are popular on spas and above ground swimming pool pumps. NOTE: Sometimes these motors are also labeled 48Y frames, but they are not square flanged 48Y frames. Once you determine the frame, click on the link and view some motors to help determine horse power by analyzing the amperage comparisons.
