As the windings begin to cool down, the overload protector will automatically re - s t a rt the motor. The appropriate part number is listed in each illustration, just in case you need to order the complete wiring diagram or connection label sticker for your motor. If it’s accidentally flooded, have it inspected at a A.O. Smith authorized service center. L U B R I C A T I O N motors are double sealed, permanently lubricated. If it appears the bearings have failed, simply replace them. To prevent electrical shock when touching the motor, be sure windings and capacitor are securely grounded to the ground term i n a l which should be used in conformity with local codes. MOTOR FAILS TO STA RT (hums, tries to start, blows fuse or trips bre a k e r ) 1.Check the motor connections after TURNING OFF. If you hear a grinding sound, disassemble the motor and check: the conditions of bearings, a rotor rubbing the stator, c o rrosion, a cracked frame, clogged fan or o b s t ruction(s). Tighten loose nuts, bolts or set scre w s. 2.If a noticeable drag is present, check the bearings and bearing load spring. 3.Make sure motor fan moves freely and rotor isn’t rubbing stator. A bulged capacitor indicates failure on most motors. But with a Centurion, the only way to verify a failed capacitor is with the ohmmeter. Then remove the electrical cable or conduit from the end frame. D o n ’t reuse a bearing that is removed from the shaft. 7.Install the new shaft bearing(s). It is important to press only on the bearing inner race. When ordering part s, refer to the part number and serial number on the motor nameplate. The serial code on the nameplate is made up of thre e p a rts: serial letter (year), serial number (month), and manufacturing sequence number. Login to post Any suggestions? Either the spider gasket is bad or there is a rip or tear in one or more of the filter grids.Hope it helps. RobI shut if off but am wondering if it can be repaired or if it has to be replaced.

Page 22 MOTOR TROUBLESHOOTING capacitor using an ohmmeter (see “Troubleshooting A Capacitor” page 23). 5.Rotate the motor shaft. If you hear a grinding sound, disassemble the motor and check: the conditions of bearings, a rotor rubbing the stator, corrosion, a cracked frame, clogged fan or obstruction(s). Repair or replace any faulty part(s). 6.If the motor has a switch, disassemble the motor and check the contacts for dirt. Use brown Kraft paper to gently clean. If the motor still doesn’t work, replace the switch. Page 23 1.Mounting, motor coupling and brackets. Tighten loose nuts, bolts or set screws. 2.If a noticeable drag is present, check the bearings and bearing load spring. 3.Make sure motor fan moves freely and rotor isn’t rubbing stator. Look for loose or binding parts inside the motor or pump. 4.Check for malfunctioning motor start switch and governor. Page 24 MOTOR TROUBLESHOOTING 6.Check the start switch for broken contact welds or a broken spring. 7.Check the capacitor with an ohmmeter. A bulged capacitor indicates failure on most motors. But with a Centurion, the only way to verify a failed capacitor is with the ohmmeter.

Heat can damage a motor’s windings, insulation, bearing lubricant and run capacitor. In short, heat can quickly decrease the service life of a motor. Remember, proper ventilation is always a crucial consideration when installing a motor. If at all possible, install a motor in a location that is free of dirt, dust or airborne debris, such as leaves. Page 15 Century and Neptune motors have superior resistance to moisture, but you should avoid placing the motor where it can be splashed. Avoid installing the motor in low spots where it could collect water and be flooded. In fact, it’s probably a good idea to elevate the motor at least two inches off the ground. MOISTURE Before you turn the motor on, check to see that the line voltage, phase and frequency match the specifications shown on the motor nameplate. Page 16 The task of wiring your motor is fairly simple. The wiring diagrams shown on the following pages are color-coded for easy reading. The appropriate part number is listed in each illustration, just in case you need to order the complete wiring diagram or connection label sticker for your motor. Make sure the connections are tight to prevent failure or overheating. If you do find loose connections, check for excessive vibration. Page 17 WIRE SELECTION GUIDE THE SIZES SHOWN IN THE FOLLOWING WIRE SELECTION CHARTS ARE RECOMMENDATIONS ONLY.It should be located away from direct sunlight and other heat sources, such as laundry appliances and water heaters. Provide for ample air circulation around the motor. Clean the air inlets as required, making sure that the POWER IS OFF first. COOLING Whenever the motor must be shut down for extended periods, be sure all surfaces, vents and interiors are dry to prevent rust. Page 20 MOTOR TROUBLESHOOTING Before you even touch the motor, MAKE SURE THE POWER IS OFF. Always turn the power off at the electrical service entrance fuse or breaker box, to prevent possible electric shock.

When confirming a replacement motor's compatibility be certain that the Frame does match or it will not bolt on to your pump housing.Tip: Dual voltage motors are set to 230v from the factory so if you plan on using it for the lesser voltage is sure to switch this setting during installation or you may damage your motor. Amps - this is the power consumption of your motor, the higher the amps the higher the electric bill. Your specific pump may have an Energy Efficient motor available as a replacement. Check our Pump Motor section. Time - Pool pump motors are universally rated a CONT (continuous duty). Meaning they run constantly without needing to be shut off RPM - This stands for Revolutions Per Minute, single speed pumps run at 3450 rpm with dual speeds running at 3450 on high and 1725 on low.But I now need a new capacitor my B2853 century Something like 10-inch thru-bolts. Or the four bolts that connect the motor to the pump. For the latter, we would need to know the model number of the pump housing. Brother took apart off terminal he forgot how it was took pics but not clear view Cat: B855. Serial:31514CH. Part: O-177897-22What is the part, catalog, or model number from the motor label. See the above guide for examples. Are you sure, those are the Catalog, Part, or Model number and not part of the serial? Thanks in advance The part number 7-187554-01 does not cross-reference to any motor in our database or catalogs. On the HP and SF reading I have dashes. But then next to the label I have a smaller label that reads HP Can you see that info on the motor label? C48D48701 with a 1HP. Is this a valid number? Thanks! The same goes for the performance curve. It is matched to the pump and not to a motor. I need a replacement motor. Can someone guide me to the right part? The motor is a part of the pump, so if there is a motor there is a pump. When programming the Low Level configuration.level 1 is without circulation etc. 1 pump and 2 speed.

What i can't determine is if mine does indeed have circulation so i choose correct configuration If you search the part number in your original post 7-177781-02, it comes back as a two-speed motor. You may want to contact the manufacturer Nordic Spa if still are not sure what you have. How would you continue to troubleshoot this problem? A couple guides to check out first would be: How To Use a Multimeter to Test a Pool Pump Motor - Winding Resistance and How To Troubleshoot a Pool Pump Motor - Motor Shuts Down The B854 can be fitted to dozens of pump models, and those pump models have different flow rates. There are pumps for high head and medium head situations. Entry level pumps that can pump just enough and then premium high performance pumps for large pools. Essentially, there is more information needed to properly answer this question. To calculate the watts, multiply the voltage by amps. I'm planning to run the pump, using Solar energy, you know, panels, controller, battery, inverter an then the motor. Watts info. not on label, can anyone answer, this one. You will need to identify the Motor Part Number on the nameplate. This sample nameplate shows the location of the part number.

For Amperage Check 1.Remove the leads from the volt-ammeter if attached. Select lowest reading amperage scale according to motor nameplate rating. 2. Page 26 MOTOR TROUBLESHOOTING bearings because this could damage the motor and cause a return service call. 1.TURN THE POWER OFF 2.Remove the cover from the motor and disconnect the electrical supply leads from the terminal board. Then remove the electrical cable or conduit from the end frame. 3.Remove the motor from the pump unit. 4.Mark the brackets and frame of the motor, to assure correct alignment of these parts when reassembling them. 5. Page 27 6.Remove the bearing(s) from the motor shaft, following these steps as necessary: a)Remove shaft collars used to secure bearings. Don’t reuse a bearing that is removed from the shaft. 7.Install the new shaft bearing(s). It is important to press only on the bearing inner race. The bearing will be damaged if the outer race surface is pressed. a)Fan end. Place the short end of the shaft on a wood block. Place the bearing (and other parts used) over the long end of the shaft. Page 28 SERVICE f your pool or spa motor should need attention while still under warranty, we require that you have it serviced at a Authorized A.O. Smith Service Center to qualify for warranty coverage. When ordering parts, refer to the part number and serial number on the motor nameplate. For your convenience, a separate Century Stock Pool and Spa Motor Parts List is available.

Click Here to Find Your Replacement Pool Pump Motor Working seals and gaskets are vital to the health of your pool pump. A malfunctioning shaft seal will cause water from the pump to leak into your electrical motor causing it to fail prematurely. A GOKIT includes the complete set of your pumps gasket's and O-rings, including the shaft seal.These are the Catalog (CAT) or Part number. The catalog number is generally listed in the upper left of the label. Century’s CAT number format varies from pump to pump. For example a Pentair pump Century motor may contain a CAT number formatted like B2853 or BN24, where as a Sta-Rite pump motor is formatted as USQ1102R or SQ1202R. If your motor label contains any of these variations a simple search in Inyo's search engine will find the exact motor match.To make this a searchable number first, you must remove the first set and third set of numbers, this will leave the middle six digits. These six digits are worth their weight in gold. If you input them into Inyo's search engine an exact match can be found.The pump model number is located on a tag somewhere on the wet end of the pump usually near the outlet port.From there you could click the results and follow a link to the parts breakdown to show a complete parts listing of the pump. Click Here to Find Your Replacement Pool Pump Motor The information most necessary to confirm compatibility is Horsepower (HP), Service Factor (SF) and Frame (FR). Similar to your car engine the higher the horse power the more it can move.Service Factor is broken down into two categories Up Rated (1.27 and below) and Full Rated (1.30 and up). When selecting a replacement motor be sure that you are selecting a motor with the same HP in the same category of service factor.Most pool pumps have a frame of 48Y, 56Y, 56J or 56C.

This Capacitor together with the Start Windings provides an increase of 150 -175 % of torque to the motor shaft during its initial startup. The start capacitor will generally be rated at 50-400 MFD and 125 or 250 VAC. If your motor won't start and hums when you try to turn it on, you probably have a bad Start Capacitor. Please click here to view capacitors. If the contact points don't line up correctly, you may have to replace them.When the motor is off, springs on the arm of the governor cause the arm to come in contact with the bottom of the start switch causing the two contact points on the switch to come together and close the start winding circuit. When the motor is turned on, the rotational force of the shaft causes the weights on the ends of the governor to spin out. When that rotational force is greater than the force of the springs, the arm on the governor drops down and the contacts on the switch separate and disconnect the start capacitor circuit. With age, the governor will sometimes stick open so that when the motor shuts off, the start circuit will remain open and the motor will not restart.If this Board is damaged you may have to replace it. Please click here to view the pump motor parts. When the motor amperage exceeds max amps, the motor will overheat, and the Overload will shut the motor off until it cools. If the motor keeps cycling on and off, you either have a defective Overload or some other problem with the motor.With the right tools, you can replace these bearings yourself.The fan is mounted just behind the front motor bearing. Occasionally the blades of the fan will be damaged and will need to be replaced. Please click here to view pool pump motors.

My fan has a crack on the hub and the armature shaft is rusty. I know I'll have to remove the rust as step one. We hope to produce these guides in the offseason. I tried searching for that motor part number bu nothing cross-references to it. Can you provide me the microfarad rating on the capacitor's shell? Is that avalibale The format of those numbers do not match the part, catalog, or model numbers of a 1081 type. Click Here to view the pricing and part number. Hi there. I have a 2 speed motor by AO Smith - part 7-k56aa13a04-05. Which capacitor(s) would I need for this one? The motors part number is O-193987-24, SN30510CH. What bearings do I need? I need a capacitor for a 1hp so Smith motor For an example of these numbers, look at any of the previous comments. Butch I don't think that is a valid number any longer. The frame says p56y. It’s a single phase 1 hp motor. Part says 0-193985-04 and serial is 24811ch type cx. Not sure what bearing to get to replace mine. That motor would require two 6203 bearings. The motor number is K48M2P105B3. 5 After a few google searches, the only results I could find with that part number were for salvaged end bells from old motors.

Daniel Y. 5.0 out of 5 stars When you lose a pool pump motor, the first thing you check is to insure it is not locked up (still spins). If those are fine, your motor windings are probably shot. This motor was an original equipment motor at a great price and delivered in a timely manner. I generally always buy a new backing plate. The summer Texas heat and the motor heat causes the plastic of the backing plate to dry rot and you will find the brass knurls for the motor mount bolts falling out leaving you nothing to attach the motor to the plate.I would NEVER buy this motor again. Apparently AO Smith makes a lot of these motors and puts whatever name on them that the company buying it wants on it. My original motor lasted 15 years, (not an AO Smith motor) After talking to several pool repair guys I know, they tell me also to stay away from AO Smith motors. I plan on doing just that. They are cheap Chinese motors.I was nervous turning the power back on even though I was pretty sure I got it right. Here is a picture of my wiring so the next poor soul doesn't suffer like I did. There are many other variables, so follow my pic at your own risk.I just re-used all original O rings lubed with Magic Lube, all is good and no leaks. Received this order over night with Prime.Story: bought a motor and when installed motor wouldn’t run so I had to return it (also contacted vendor and Amazon).

I requested an immediate replacement due to defective item and I needed the motor urgently. They doubted my diagnosis and waited until received motor and tested (they said motor was fine). I’m electrical engineer working with motors all my life that I could troubleshoot pretty good. After several days they said motor was good but still refund my money. Ordered new motor again and this one work good with same wires and power.I had a problem occur that made my pool guy think the motor was defective, I contacted the seller to find out what the warranty was, the seller suggested we have the power checked for proper voltage and that was the problem. Turns out the timer box that turns on the motor was the issue. Goes to show that just because it has power doesn’t mean it’s bad, make sure you have 230 volts first before condemning the motor. Lesson learned and a potentially expensive lesson was avoided.Installation is easy, taking the old one out could be a Challenge. Also the routing of the cables through the pipe is time consuming. But still as saved hundreds soo g it myself. I hope is as reliable as my previous pump, it is a bit quieter.With Amazon Prime can be delivered within two days when you want to avoid your pool getting cloudy or worse. I have two big neighbor Oak trees on each side of my pool in Florida. No screen. I have inline leave catcher a big skimmer basket and big basket right before pool pump motor. I need to clean them twice a day to avoid pool pump straining especially in March and April. Because of the leaves and pollen I end up replacing my pool motor once a year on average. I think the reason for short life of pool motor is my pool setup. This motor did better than another that lasted only 10 months. I have not found a better motor. I bought this pump twice and will buy again. Commonly found on inground pool pumps such as Hayward Super Pump, Maxflo, Super II and many other pumps requiring a 56J frame motor.
