How to replace bearings


Must disassemble the pump from the motor. The impeller has RH threads so hold motor armature (do not damage it) and turn impeller CCW to remove it from end of shaft. Hold armature in left hand and rotate impeller with right hand, turning hand on impeller back toward your body, or top of impeller toward you. Don't know how else to describe it. Once you have the impeller off everything should come apart pretty easily.
If impeller is really stuck, you will need to figure out how to hold it evenly all the way around without putting pressure on blades. Strap wrench, home made jig, something that can put more pressure on it than your hand.
You may want to remove the motor field so that you can grasp the armature while removing the impeller, do this by removing the long screws from the end of the motor.

Gently pry, tap, slide, however you can, get the bearings off the armature shaft without damaging any parts attached to it like fans, or starter centrifugal weights. Those things can be removed if needed.


Put new bearings on by sliding over shaft and seating in place by driving against the center race only. Do not drive bearing on by striking the outer race to move the inner race, this will damage the bearing.

I have a Sta Rite Model ANC 30L Code 1F93C and I need to remove the impeller to clean accumulated manganese build up- I pulled the 4 mounting bolts and am afraid to pry for fear of breaking something- any...


When you open the pump up look to see if you have a set screw in the center of the impeller. This is a left hand screw, start by removing it. Remove the diffuser from the front of the impeller. Quite often you can just take a screwdriver and wedge it into the left side of the impeller and hit it a good shot with a hammer straight down to break the impeller free. Then just screw it off.
If that dosn't work then you have to open the back of the motor and get to the end of the motor shaft. The end will be squared off so you can get a wrench on it. Then take a big pair of water pump pliers and get the front impeller and unscrew it.
The metal in the impeller and the steel shaft will stick to each other so you will have to break it free. At that point the seal plate will come off.
When your done and putting it back together be sure to replace the seal and all the "O" rings.
Good luck.

I have a whisperflo. I've ran the motor without water and it's quiet. Add water and it makes a pretty good racket (not a bearing whine). I've even tested without my filters to eliminate head pressure) ...


Yes the impeller is screwed on right handed normal thread. *** Info below pasted form one of my other posts *** You need to lock the motor and unscrew impeller. Depending on the motor, you remove a cap in the middle of the tail piece and hold with a wrench, (usually 9/16") 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. (you already did this.) 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.

Have already disassembled down to impellar. how does the impellar come off


Check to see if you have a center screw in the impeller. If you do then it will be a left handed screw. You will turn it clockwise to get it out. Then I will usually take a screwdriver and insert it on the left side of the impeller. Then give the screwdriver a good sharp hit downward to break the impeller free, then just unscrew it. The brass center on the impeller will stick to the stainless steel on the motor shaft and you just have to break it free.
If this dosn't work then remove the back of the motor and get a wrench on the back of the shaft, then find a way to grab the impeller and unscrew. Good luck

How do you remove the motor from a Flotec FPS5172, 1-1/2 HP.


The impeller screws on the motor shaft. First replace the through bolts in the motor. These are the long bolts, they will just cause headachs. On the back of the motor their will be a place to hold the shaft from turning, If you hold the shaft the impeller just unscrews. If you look in the center of the impeller it may have a set screw holding it to the shaft. If you have one of these it will be a left hand screw. Then you will need to break the impeller free as the brass that holds the impeller on will stick to the stainless steel of the shaft. Don't let how tight this is fool you when you put this back together it just goes on hand tight. Good luck

LG Steam washer will not pump out. Displays "OE" error signal. I have followed the instructions and cleaned the outlet filter, but it still will not complete a cycle.


OE is really DE (drain error). If the filter is not blocked, then check that nothing made it past the filter and into the pump impeller. Also, if the pump impeller has come loose from the pump shaft, you will have to change the pump motor. Just pushing the impeller back on will only result in it coming off again. I don't know if any adhesive on the shaft would solve that issue. I've never tried that as I didn't want a call back.
Pop the rectangular recess out from around the filter area. (putty knife at the right and left edges).
Remove phillips screws.
Tilt washer back.
Reach under washer and remove pump. (there is a tab on the bottom which locks pump onto washer base. If you break the tab, don't worry about it, the screws will hold the pump in place just fine)
Impeller does not just spin freely. It turns a third of a revolution at a time as you turn it by hand.
Remove any object or replace motor as needed. Motor held onto pump housing by three screws also. If you would have posted model number I would have listed part number.

Pump disassembly


I removed the impeller on my DW761UQB. The instructions were molded into the plastic pump housing. This is how I DID MINE: Remove motor mount screws. Remove the chopper screw (screw only goes into impeller, not motor shaft). Remove chopper and rotate/remove strainer. Place socket or wrench on impeller tip and place another wrench on rear of motor's plastic fan. Unscrew fan from impeller shaft ( threads are LEFT handed, turn CW). Once fan is 'backed off' of the impeller, CAREFULLY pry the motor/fan from pump housing (impeller is attached to motor shaft via splines). Don't crack the delicate plastic pump housing. Mine was stuck, but separated with moderate force. Now remove the impeller/seals from the pump housing. This worked for MY above mentioned model, I don't know what other models it applies to. I am not a pro.

LG LE Error


The broken wire would be where the wires pass from the bottom of the door into the dishwasher body. A more likely cause may be a motor problem. A number of main motors have had problems with the magnets coming loose or breaking up, resulting in the LE code. You can remove the phillips head screws around the sump cover to gain assess to the impeller, which is attached to the end of the motor shaft. (via a LEFT HAND THREAD screw.) Turn the impeller by hand and listed for noise. Shaft should turn freely, smoothly, and quietly. If it does not, remove the impeller and the cutter bar, remove dishwasher from cabinet, lay it on it's side, and remove four phillips mounting screws from motor and wiring. There is a two year warranty on all parts.
