Broke the thread off the water pump impeller shaft. How do you get it out to replace it. The part looks like it has a thread but I locked up the engine and tried getting it of with a spanner clockwise but it just turned without undoing.Puzzled ? Thanks.

    Thanks ollie. The impeller broke off the shaft while doing a little slide down the road. Wore a hole in the water pump cover and alloy must have jammed the propellor and snapped the threaded shaft end.
    Its the shaft comming out of the engine I need to replace.Not sure if it screws out or if you have to split the engine. My manual does'nt cover this and our bike shop doesnt know.Sorry I should have explaind it better. What do you think.
    Many thanks.

    Hey Ollie. Have got the pump cover off. The clutch cover not that easy . Loosened off the cable at the bars,undid the 11 bolts as per the manual but the cover is held with something behind. Dont want to force it to much.
    What you think.

    Cheers Phil.

    ok buddy you dont need to split the engine but take the right side cover off watching the gasket as you do this the water pump is driven by a gear inside which may have wore as it jammed up or the shaft snapped inside so do this first and get back to me again buddy

How do you remove the impeller on a mission magnum centrifugal pump?


Open up the pump housing, by separating it into 2. Reveal the impeller. If there is a center screw in the middle of the opening of the impeller, it will normally be backwards threads. Remove that.
know if the impeller should unscrew off of the motors shaft, that will be normal threads. But, to do that, you will have to lock the shaft from spinning. Remove opposite side Cap on the motor, to reveal the shaft. Either use a wrench or flat blade screwdriver to lock the shaft. Now unthread the impeller from the motors shaft.

How to replace impeller on guolds j10


What is the make and model of the "pump"?
Gould is a motor manufacturer.
The manufacturer of a pump, will use a third-party vendor like Gould, to provide them a motor for their pump. Gould is Century/Magnetek, which is now AO Smith.

BUT...
remove pump housing/volute covered, and access the impeller. Then on the back of the motor you should be able to access the shaft. Lock up the shaft so it does not spin, and then unthread the impeller. Some pumps, especially two speed pumps, will have a locking screw in the center of the impeller. That screw will be counter threaded or backwards thread. It keeps the impeller from spinning off the shaft during normal operation between high and low speeds.

again if we had more specific information, we would be able to assist you better.

Removing impeller from OJ800 water pump


The impeller has a reverse thread locking screw through the center. You can secure the motor shaft by putting a 9/16 open end wrench on the other end of the shaft, which is under a cap in the middle of the rear of the motor.
Check your seal plate carefully. Whisperflo is a great pump but they don't take heat very well. It is very common for the seal plate to also be damaged when the pump runs hot, particularly the lower inserts where the bolts screw into.

Hi, I have a waterway executive 48 spa pump and need to replace the seal on the pump shaft. How do I get the impeller off the shaft to access the seal.


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


Removing the impeller requires you lock the shaft as you turn the impeller off counter-clockwise. You will also need to check for an impeller screw in the center of the impeller inlet. If a screw is present they are usually left hand thread. Back out the screw first, then proceed to remove the impeller.


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.

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.

How do I get to the pump seal on my hi-flo water


The impeller threads off the shaft and most likely is right hand threads. You will have to lock or hold the motor to remove the impeller. If you remove the motor cover you might find that the motor has a slot in the end of the shaft or two flat sides so you can hold it with a flat wrench.

The impeller is probably plastic and could break. Get a strap wrench to remove the impellor.

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.
