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.

SOURCE: Jacuzzi magnum pool pump impeller broke

The impeller on the Magnum pump unthreads counter clockwise as do other impellers. There is a shaft of the motor that runs the length of the motor, on the back of the motor when you take the bell housing off you will see a small silver spot with a **** in it for a standard screwdriver. Put the biggest one in there you can and then grab the impeller and turn it counter clock wise and it should unthread. Sometimes they won't if it has been on there a number of years. You will need to break it off if it doesn't unthread. Then just purchase a new Impeller for the Jacuzzi Magnum Pump.

SOURCE: We are having issues getting the impeller apart on

I believe the jacuzzi pump impeller has a locking screw directly in the middle of the impeller. You'll have to turn it clockwise to remove it. Then you'll need to remove the cover from the back of the motor using a 1/4" nut driver. Depending on the motor, you should be able to use a 7/16" open end wrench to hold the motor shaft from turning as you turn the impeller counter-clockwise to remove it. Some motors are different, some have a keyed shaft or require a special tool to hold the shaft while the impeller is removed. Hope this helps.

SOURCE: I'm looking for a replacement impeller for a 1 1/2

Hi, If you have removed the old impeller, the part number will be in the center. If wear has obliterated the part number, then the replacement impeller will be either spx1610-c for medium head or spx1611-c for a high head. Later models of super pumps will have a 2600 series of numbers for the upgraded drive train. However, the 1600 series drive train parts are still available.

How to change the seals on a jacuzzi magnun force 1 hp pool pump


Hi,
If you haven't already figured out how to change the seals on your Jacuzzi Magnum Force pump, I can help by supplying a diagram.
Here is the parts explosion for that pump.
Start by removing the case/basket assembly, then the diffuser to get to the impeller. Loosen the impeller to get to the seal plate.
When going to the trouble of changing the shaft seals one should change all the hosing seals at the same time because its a lot of work.

I am trying to replace the motor on a pool pump. How do you remove the front end or impeller to install a new motor?


it may have a left hand thread screw in the front of the impeller turn this screw clockwise to loosen, to loosen the impeler just use a 7/16 or a 9/16 wrench to hold the back of the motor shaft look close you will see a slot in the shaft for the 7/16 wrench just under the centrifugal switch , this will hold the rotor still so you can turn the impeller counter clockwise to remove it

How to dismantle a jacuzzi magnum pool filter pump 1228


When you go to loosten the lock ring you will need to find the lock tab that will keep it from comming off. This tab I think will pull out but it may push in and this will free the ring to turn. Once this is off if the motor runs turn it on for a second and let it push the front and back half apart. If it won't run you can use a flush bag to pressure it off. In worst case you can pry the halvs apart with a big screwdriver. If you do this be careful not to hurt the case of the pump it is just plastic.
When the pump is opener you remove the difusser and look inside the impeller. If you have a screw in the center of the impeller it will be a left hand thread so to remove you will turn it clockwise. Now just unscrew the impeller turning it counter clockwise and take the rear plate off the motor by removing the four bolts on the back. Good luck.

The impeller is threaded onto the end of the motor shaft and the housing (pump body) is attached to the motor with the same bolts that hold the rear cover on the motor they run all the way through on most pumps.

Pump does not turn on except for a humming sound and shuts off jumping the electric breaker


This could be anything from a stuck impeller to bad windings in motor. If you open the pump at the lock ring and remove the difusser from the impeller you can see if you can spin the impeller, If it won't move is it something holding the impeller up remove it. If notit is probally a bad bearing and you should replace the motor. If the Impeller turns try turning it on and caerfully try to spin before it kicks the breaker. If it is sort of stuck and does not want to turn the motor is bad and needs to be replaced. If it spins and won't start same thing, If it spins and starts it is probally a start capicator. Shut the power off at the breaker remove the back of the motor the capacitor will be a small black or silver cylinder with 2 or 3 wires clipped to it. Remove this and take it to a motor shop and get an exact duplicate. and that should fix it. When putting back together be sure to lube all "O"rings and refill with water. Hope this helps.
