Disassembling the pool pump to change the seals

You probably overheated the pump bearing. No offense but if it was a cheap pump on a plastic pool, the shaft seal might be damaged also. If it was mine and if the seal isn't completely destroyed, I would try to disassemble the pump to expose the seal. Then I would take a can of Pam or other pan spray, start the pump and spray the shaft where it comes out of the seal. This is food grade vegetable oil and won't pollute your pool water. If you don't soak it in spray, there will be so little that it shouldn't affect you filter either. In the cheap pumps, the seal and bearings are usually molded into the housing and not repairable. If this doesn't quiet it down, live with it until it lock up, (just don't let it run unattended), or replace the pump. Good luck.

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.

Question:

What do I do if my pool/spa pump is loosing suction or prime?

Answer: by Osko Pool n Spa Pool Pump Losing Suction or Prime If your Swimming Pools Filter system looses Prime, it is caused by one of the following conditions.
Note: The lost of suction/prime is caused a leak which in turn sucks air into the system. The lost of suction/prime will be anywhere from the Main Pool Skimmer(s) to the Pool Pump. It will NOT be from the Pool Pump to the Pools Main Return(s).
1) First make sure that your water level is high enough so that the skimmer is not sucking air.
2) Check the Pump Pot Housing Lid Seal and be certain that its completely sealing and is not
Sucking air into the system. Check the lid for cracks. If either condition is true, replace the Pump Pot Lid Seal and/or entire lid
3) Check all fittings, clamps and hoses from the pools skimmer to the Pools Pump Pot Housing for wear, tightness and leaks.
4) Check Pool Pump Pot Housing for cracks.
If everything aforementioned in good working order, the next thing to check is the Pump Pot Housing Main Seal and the Pumps Impeller and finally the pump.

5) While the Pool Pump Motor is running, carefully inspect the area where the Pump Pot Housing attaches to the Pump Motor. See if there is any water leaking. Next, spray the area with water and see if the water is sucked into the Housing. If so, your Main Seal is damaged.
6) Disassemble the front half of the Pump Pot Housing from the back half and inspect the Pump Motor Impeller. (This is a high suspect part). See if there is any sign of wear or breakage. (This happens over time from debris in the water passing over the impeller). If so, your Impeller is damaged.
7) Re-inspect the Pump Pot Housing Main Seal by standing the partially disassembled upright, with the Pump Motor towards the ground. Pour water over the impeller and into the cavity. See if the water leaks thru to the outside of the Pump Pot Housing. If so, your Main Seal is damaged.
8) Remove the cover from the rear of the Pump Motor. Using a large standard blade, (straight), screwdriver or wrench... turn the main motor shaft. Listen for grinding and/or rumbling and feel for any restrictions while turning. If you hear or feel either, your bearings and/or brushes are damaged.
If everything seems to be in good working order, then you need a new pump... not just replacement parts

Disassemble the pump to the point where you can see the whole impeller. Then turn the power back on to verify that it is the bearings, and not trapped debris causing the noise. If it is the bearings the short answer is to replace the motor.

Bearing failure is usually related to a leak at the pump seal. This results from either a faulty seal installation, or the pump running excessively hot (from running w/o water).

When replacing the motor carefully examine the seal plate (where the seal is set) front and back for any cracks or deformity. If the new seal doesn't set exactly, it will leak.

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.

There are four through bolts. The heads to these are on the far end (capacitor/wiring side of the motor). Use a 1/4" socket to remove the long skinny bolts. It took me a while to find them because it looks like there are holders for screws on the back side of the seal plate, but these serve no purpose.

I think you have spun the center out of your impeller. Disassemble your pump and replace the impeller if necessary. Also replace all seals while you are at it.

You have to completely disassemble the pump and motor to replace a seal and the bearing(s). It is better to take it to a local electric motor repair shop if you are not sure how to complete these repairs. We charge about $60 total for the job and guarantee it a year. Most shops should be about the same.

You need a 201 seal for the pump. Most electric motor shops that work on pumps and of course pool store carry these. If you are unfamiliar with how to change the seal, the charges to have it done are usually low. We charge $15 - $30 depending on how much of the pump is brought in and therefore remains to be taken apart to replace the seal. The seal is about a $5 item.

If trying yourself, you will need to completely disassemble the pump, lock the motor shaft at the rear of the unit, spin off the impeller, and replace both halfs of the seal.

The pump seal is bad on the unit. This requires disassemble of the pump unit. Remove power to the unit, dissasemble pump housing, remove the impeller from the shaft of the motor by removing the allen screw with an allen wrench. Seperate pump housing from motor remove the old seal replace seal. Lube motor shaft with a little clean oil or wd40 to facilitate easy install thru new seal,reassemble in reverse.
