Can my shaft spin and not my impellor. how can i check

the impeller is usually screw onto the shaft or the shaft has a D (flatspot on one side to lock impeller) so no, the shaft cannot spin without the impeller moving unless the shaft is snapped or impeller is totally stripped (ive never seen either)
if the pump is running but not pushing water, take the wet end off and make sure there is no debris (leaves, worms etc) caught in the impeller fins. you will be amazed at how much that will reduce the performance of a pump

Replace pool pump impeller

NO, should have just a little resistance, you might have a hayward and the o-ring sticks to the impeller shaft and must be removed. OR you have the rotor bearings installed wrong, this too will cause improper shaft clearance.. should be a easy fix. good luck and vote if'n I was of help.. jay the pool pump motor repair guy longwood florida

I have a Pentair 2.0 pump that I am trying to remove from the impellar. The shaft turns allowing me to turn the pump part itself but I can not pull it loose from the rest of the housing. How exactly do I...

The impeller is threaded onto the motor shaft. On 2hp motors and above, there is usually a screw with reverse threads to help secure impeller to shaft. To remove impeller, first remove screw(reverse threads) Next, remove back cover off motor. The shaft either has a slot for a screwdriver or flats for a wrench. Hold shaft and unscrew impeller.

How to strip pool pump, pantera bearing has pack up

You are probably wondering how to remove the impeller - generally, these are screwed on to tha motor shaft - motors normally run clockwise when viewed from the rear, so thread is normal right hand. remove fan cowl and fan from motor in order to be able to restrain the shaft while you unscrew the impeller - it should be straightforward from there.

Bearing failure is more often than not brought on by leakaege from the mechanical seal - when you reassemble the pump you should replace the seal assembl - also make sure that there is no damage in the form of melted plastic around the seal stationary seat area; replace parts as necessary.

Pool sweep pump stuck and will not turn.Binding on impeller to rubber seal.How to disassemble remove impeller and seal.

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.

My Hayward just hums when I turn it on and after a few seconds the breaker pops.

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.

How to get impeller off hayward power flo sp1525

Once you have the housing apart, 6 screws/nuts I believe, make sure you have the power completely shut off at the breaker. Remove the rear housing on the motor to expose the armature (shaft). Depending on the motor, you will need a 7/16" open end wrench to hold the shaft, be careful not to damage any components, you may have to remove the capacitor or switch to access the shaft. Once the shaft is being held, try to remove the impeller by turning counter-clockwise facing the impeller. If it will not move, you may have to use an impeller removal tool. c85eef7.gifMost pool supply places have them. Be sure to install a new shaft seal, its best to replace the seal anytime you mess with the impeller. Having a good shaft seal will save your motor bearings.

This video helps, although its not the same pump..

I hope this helps....

This is a sign of a faulty drain pump impeller. the drive shaft that is connected to the impeller is stripping the impeller. you will eventually need to replace the entire pump soon.

I disassembled the pump but I can't get the impeller off. It's stripped and needs replacing. I don't want to force it and break something else. What is the best way to remove the impeller? It's the No

I broke the outer circle of the impeller off with a screw driver and then used a Dremel tool to cut the plastic down to the shaft so I could break if off the threaded shaft.
