The pump hardware parts are matched to the pump housing and not solely on the motor. What is the model number or make and model of the pump housing?

whats the difference between a st1072 and a ust1072
Reply
Hugh, The ST1072 if a full rated motor (high service factor) and the UST1072 is an up-rated motor (low service factor). You need to match the horse power and service factors among other specs to make sure you are buying the correct motor.

I have a leak on my Hayward booster 5060.. when I turn on the booster the leak appears to be a pressured stream coming from the seam of the volute. Will this leak compromise the pumping or suction action on my piping system even when not activated? (It does not leak when not in use)
Reply
Hi. If the leak is not resolved it will get worst causing a major issue with the pump, and or the performance of your cleaner. It may not be an issue when the pump is not running but it just depends on the severity of the leak.

I'm looking for the proper replacement booster pump for a Hayward Model 5060 series 8d07. The current motor has a SF of 1.85 and a HP of 3/4, totalling 1.3875 HP. According to your own info replacement motor HP should be equal to or greater then the original. But the motor you list as the replacement In another Q/A for the 5060, is the SPX2707Z1M with a square Flange. Also you list the ST1072 which has a round flange. Neither meet the HP requirment as my current motor. So which is it?
Reply
Hayward has part number SPX2707Z1M for the replacement motor for that booster pump, but you could also use part number SQ1072 for that booster pump. Also, that booster pump requires a square flange motor not a round flange motor. The shaft seal you will need for your motor install is part number 3260-105.

Does this motor have a starter capacitor under the motor housing? If "yes" what is the replacement part.
Reply
Yes this motor does have a start capacitor which is located underneath the motor cover on the back of the motor. The capacitor # for this motor is a 610807-002 Start Capacitor We also have a Video on How to Replace a Pool Motor Start Capacitor which you may find helpful.

Hello, Mike. The PART#BN24 3/4 HP 115V Thru Bolt Motor and the PART#BN36 3/4 HP 2 Speed 115V Thru Bolt Motor are the options for replacement motors. The Hydramax Shaft Seal Assembly will also require replacement anytime you replace your motor. The part numbers available for those are PART#5111-03 (Generic) and the PART#5111-03C (OEM).

I'm looking for a inground pool Hayward booster pump model C48K2N143B4, SER NO.8E06, Model 5060, is this pump? Thanks
Reply
Hi, The SPX2707Z1M motor is the correct replacement for the Hayward 5060 pump.
Reply
Hi, The replacement for my current motor is listed as UST1072. It seems the only difference from the ST1072 is the service factor. Can I use an ST1072 instead of a UST1072 or is the service factor a game breaker?
Reply
The ST1072 is a stronger motor so you may need to change the impeller if it was originally set up for the UST1072. Also the filter may not be able to handle the extra water pressure.

I'm trying to replace the motor on my pool pump but all these numbers and abbreviations on the motor label are really confusing me. What do they mean?
Reply
Replacing a pool pump motor is not as difficult as it seems. You can try looking here. If you need help figuring out what the information on your label means. If you are still having difficulty figuring it out you can call us at our toll free number or you can send us a photo of your motor label here.

I'm trying to find a replacement motor for my pool pump but my model number doesn't match what you have listed as the model number. My model number begins with a C48 and yours begins with an SP. Please help.
Reply
What we have listed on our chart pages is the pump model number. The model number you have will just identify the motor. If you look on the plastic housing on the pump there should be a sticker which will have the pump model number. You can usually find this by the discharge port on the pump. Once you locate it you can choose the correct replacement motor. Be certain to change the shaft seal and gaskets as needed. You can use our >How to guide if you need help.

Why should I purchase a Tune Up Kit?
Reply
A Tune Up Kit includes all of the essential replacement seals and gaskets for the pump. The seals and gaskets should be replaced when installing a new motor on your pump. New seals will prevent the pump from leaking water or losing the prime. A Tune Up Kit will protect your motor and ensure that the pump is working efficiently.
Reply
Why do I need to purchase a new shaft seal?
Reply
We strongly recommend replacing the shaft seal. The purpose of a shaft seal is to prevent water from running down the shaft of the motor and into the motor housing. Water will damage the bearings and cause the motor to fail. A new shaft seal should be installed whenever a motor is replaced. The motor manufacturer can deny the warranty if the motor fails to due to water damage from a faulty shaft seal. To find your shaft seal you will need to visit our Pool Pump Parts Page or the Spa Pump Parts Page and select your make and model.

What is Service Factor?
Reply
Service Factor(SF) is a multiplier that when multiplied by the horsepower of the motor indicates the total permissible horsepower loading that may be carried when the motor is operating at rated voltage and frequency. The most important thing to remember when replacing a motor is that the replacement motor's horsepower times its service factor must be equal to or greater than the original motor's horsepower times its service factor. The Service Factor rating can be found on the motor label. See Step 4 of our How to Read a Pool Motor Label guide.

(5 out of 5 stars) Excellent Pump Moter Replacement
Reviewed By: PoJo from Clarence, NY ()
Pros: Awesome fit - excellent replacement
Cons: none
Tip to get the impeller off the old pump moter: use a 7/16" open ended wrench - it slides in near the capacitor on the electrical side... rotate the impeller until the wrench slides into place at the end of the shaft and then one person holds the motor and the wrench while a 2nd person loosens the impeller off with bare hands by turning the impeller counter clock-wise.

(5 out of 5 stars) Jandy pump motor replacement
Reviewed By: Poolnozzle ()
The motor appears less bulky than the original motor. The fan blades are plastic while my original Jandy motor had aluminium fan blades. The capacitor is built in the end housing. The motor runs great. Good replacement. Taking the impeller off the original Jandy motor is easy. Use a small allen key in the hole opposite the capacitor housing and lock the shaft. Turn impeller counter clock wise. If your pump has been running 5+ years consider replacing the shaft seals when you have the impeller off. Check if the ceramic surface shows pitting or the edge shows some chipping and/or the teflon part shows some surface grooves. Open the end housing and loosen up the capacitor clamp. Move the capacitor and put a small wrench on the flat ends of the shaft end. This will lock the shaft. Tighten the impeller just hand-tight. Reposition the capacitor in its bracket and tighten the clamp. Put the end housing back before you start working on the pump part reassembly it will avoid damaging the electrical parts. Check the mains supply if it is 230 or 115Vac. Most pools have 230 but make sure before hooking up the motor. Remove the old bracket support insert. The rubber strip that comes with the motor will not easily stick on the old plastic Jandy Bracket. Clean the old bracket edges and use some superclue.
