Magnum Force Jacuzzi Pump stopped working

How long from the last working of that pump?
Was the Pump stored? unused?
Disassembly and try to make turns the shaft and see if it is Blocked.maybe the bearings are with water and it is rusted.
If the bearings are rusted, the mechanic seal is damaged,you need to change it and the bearings.

the pump is pumping and circulating hot water into jacuzzi, it will get hot. I think it is ok

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.

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.

This is not possible as it completely depends on the amount of total dynamic head the pump is connected to as well as the voltage level that is being applied.

most likely the bearings are starting to go.

you need to replace the shaft seal.

The number one problem is air leaks.......check all connections to see that they are tight, and rubber seals. The intake side would give you trouble with air leaks. If you dont find any leaks then I would pull the pump cover and check the impellor. Pool stores have parts and lots of knowledge.

sounds like it needs new bearings, take it to a pool professional.

Good luck...Jacuzzi went out of business. The best source I have had for their parts is CCO:
