Replace pool pump impeller

Emerson is the motor manufacturer. 1081 is the swimming pool duty motor designation. In other words all pool pump motor manufacturers have a 1081 motor. The mechanical shaft seal is going to be a part of the actual Pool pump itself. The seal is between the seal plate and the impeller. If motor is extremely noisy, then the leak allowed water to get into bearings and cause damage. If the motor is really noisy, or the shaft doesnt spin freely, then you may have damaged motor bearings. The pump manufacturer can usually be identified by markings on parts of pump ( in front of motor ).

Depending on the pump you have to separate the motor from the housing bust removing the bolts. Once the expelled is exposed, remove the cover and the back end of the motor housing the electrical wiring. You can access the shaft of the motor and hold it in place with a small box wrench. Than spin the expelled off counter clockwise. Replace the melchanical seal and reinstall the impeller. Replace the seal for the housing and reinstall the housing to the motor. Fill the pump with water again and turn the lower back on

The bearings are in the motor itself. You can separate the motor from the wet end by removing the wet end. You can then remove the cap or cover on the back of the motor to expose the shaft. It may be a hex tool, a slotted tool, or 7/16 wrench that you'll need to hold the shaft while you spin off the impeller (you may need an impeller tool as well).

Once the impeller is off, you can remove the seal plate and the motor will be isolated. You can then remove the through bolts and proceed to replacing the bearings. You will most likely need to replace the shaft seal as well.

There are many tricks associated with doing this invasive of repair. I cannot cover every scenario you might encounter. Personally, when the bearings go bad, I usually replace the motor as it's usually a number of years old and all of the components will start to go bad including the windings. These motors run at high temperature and unless you've encountered a bad shaft seal that allowed water into the bearings, it may be worth replacing the entire motor. Just my thoughts. Hope it helps a little.

YOU WILL NEED A NEW IMPELLER SPX3010C SUPER HAS 4 BOLTS OR A SPX261OC SUPER 2 HAS 6 BOLTS. JUST TAKE THESE BOLTS OUT AND THE IMPELLER SCREWS OFF TO THE LEFT, CLEAN UP THE TREADS. USE A NEW 201 SHAFT SEAL. AND ON THE MOTOR PICTURED THE SHAFT CAN BE HELD AT THE BACK OF THE MOTOR TO SCREW ON THE NEW IMPELLER.. PUT IT ALL BACK TOGETHER ,PRIME THE PUMP WITH ABOUT 4 GALLONS OF WATER. RUN IT AND WATCH FOR LEAKS .. NO LEAKS ? YOU GOOD TO GO ! ..

Thank you for posting your question here on Fixya.com.

Yes, the seal has been leaking and it needs to be replaced; probably the motor bearings too.

Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. To lock the impeller you will have to remove the motor end cover or a cap covering the shaft end depending on which version your particular motor has. Look at the end opposite the pump and imagine a shaft from one end to the other right in the center.

Once you remove the cover you will see a slot for a screwdriver, a flat for a wrench, a hex hole for a hex key or some combination of these. Lock the shaft and spin off the impeller. Some are so tight you will end up breaking them in the process. Simply replace it and the seal. Be sure the motor shaft is in good enough condition to allow the new seal to work properly. If too much shaft material has rotted away the new seal will leak soon after it is installed; you would need a new motor at that point.

Sounds like maybe your motor bearing are going bad, or have already seized up. When you say "rubber seal" are you referring to the rubber portion of the shaft seal? Either way, to remove the impeller you need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tailpiece and hold with a wrench, or remove a cap that covers the whole end and grab the shaft with a wrench (usually 7/16") by sliding it under one of the components (not sure exact part off top of my head have to look at it) and then turning impeller. If the impeller has a bolt or screw in the middle remove that first. It should be reverse thread so make sure you don't turn the wrong way and break or strip. If there is no screw, or after you've removed it, just spin the impeller off (it should be counter clockwise standard thread). If you can't do it by hand and assuming you don't have an impeller wrench, be very careful and use a large pliers, pipe wrench, or strap wrench to loosen it. After that you unbolt the motor from the seal plate, pull the seal plate away from motor (this removes half the seal), and then pop the other half of the seal from the seal plate. If the bearings are seized up then you'll have to replace the motor, or have it rebuilt.

Your pump motor or impeller is seized. Disassemble the pump housing and check the impeller to see if it spins freely. If not then check for debris, if impeller appears to be free of debris, then check the shaft seal and motor. If the shaft seal is leaking water, then the motor bearing is likely rusted and will need to be replaced. There are 2 bearings, replace them both along with the shaft seal

1 year mfgr warranty and a possible stuck impeller (from debris) or bad motor bearing(s)... You will need to disassemble the pump and inspect the impeller by rotating it and check the motor for a seized bearing and bad shaft seal. Replace both bearings and shaft seal may resolve the issue. If the motor and impeller spin freely, then you might have a bad motor start capacitor. Some motors have a mechanical governor that can get stuck on the high speed switch and the motor will not spin until that is repaired. These type of pumps require some knowledge and skill to overhaul. Seek professional assistance to prevent damage.

You will need to disassemble the pump and check the impeller. remove any debris and try turning the impeller by hand. If it does not move or is dragging, you will need to overhaul the pump. Possibly a shaft seal leak has damaged the motor bearing(s). Replace the shaft seal and motor bearings. If the motor is badly deteriorated, you might need to replace the motor. Note... the impeller turns counterclockwise to loosen. you may need special tools to grip and hold the motor shaft and the impeller to prevent damage to the impeller. If the impeller is seized on the shaft from rust, you may have to break it to get it off. reassemble with teflon lubricant on the shaft threads when reinstalling the impeller. This will prevent seizure later.

Check to see if the motor spins freely or appears to be dragging or stuck. If it does not spin freely, then you need to overhaul the pump and replace bearings and shaft seal or locate the source of the dragging in the pump housing
