sounds like it ran dry and burned up the seals between the pump and the motor

There is no lubrication required for the Jacuzzi motor. There is lube required on the o-rings. Silicone based is the best for those.RodUS Parts Center

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.

the impeller you need is 05-3818-01 for a 2 hp full rate pump model 2MF-S2
it will be 05-3819-00 if your modle number is 2UMFS-S2

you can find them at US Parts Center

Jacuzzi (Carvin) Magnum, Force & Plus pump parts are hard to find.Here is a link to our site which has a parts explosion/diagram for those pumps.Jacuzzi Magnum, Magnum Plus, and Magnum Force Pumps

Probably 1.5 HP but if you can read any of the nameplate data on the motor it would be helpful to confirm. A better approach might be to size the new pump to the volume of water in the pool.

If all you are going to replace is the pumps motor then can you provide at least the amp ratings off the motor? Those should help verify what your old unit's horsepower really is.

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.

the o ring usually would not fit if it were the wrong size. What seals is a ceramic seal, did you change that? If run without water, the ceramic seal will be damaged....

There are none; the large diameter plastic ring catches on the motor adapter plate and secures the motor assembly into the pump housing. You may still have the yellow locking tab in the ring as well. If so, one end of it will lift out of a hole; do so. Spin the tab out of the way then use a blunted paint scrapper, chisel or block of wood and a hammer to tap the ring loose in a standard CCW direction. Once the ring spins free you will need to work the pump end loose. They often stick in the housing so rock it back and forth to eventually break it free.

Sounds like a problem with the impeller, take off the lid, take out the pump basket and reach down and feel past the opening in the bottom, should feel a smooth and clean series of plastic blades, it is possible the blades a chewed up or its loaded up with hair.

most likely the bearings are starting to go.

the pump housing is available through your local pool dealer. It is broken down into 3 sections the pump, housing and Pod.

The Pool Tech

If you have any clamp on amperage meters, you need to see what the amperage draw on the circuit is when it is running. This will tell you if something is wrong with the pump circuit. It could be anything from a bad capacitor to an impeller obstruction.

rollout switch on lower inside cover by burn rack and gas valve possible down draft pushed flames into cabinet and tripped it if keeps happening might need chimney if ok check gas pressure if low unit overheated or burner tube clogged

Impeller may be broken or clogged. Turn the pump off and remove the basket. Reach back into the pump with your fingers and see if you feel debris. If you can't reach or if there is debris you will need to open the back of the pump, take off the diffuser, and clean out the impeller.

Without knowing the code it could mean anything. Consult your owners manual or online manual for error codes and remedies.
