SOURCE: Removal and installation of diffuser and impeller kit

All jucuzzi pumps are some of the most difficult to repair.Pump front should seperate from body(volute) of pump by means of screws, or some kind of band. Diffuser should have ss screws, or
be held in plsce by notches or both. Impellor spins counter clockwise to come off. Can only remove impellor with impellor wrench, or very strong hand. Rear of motor must be held in place with normally a 7-16 wrench, allen head wrench or screwdriver. Depends on manufacturer of motor. Then impellor can be removed!
Should replace shaft seal under impellor. Can seperate body of pump from motor by turning four outer bolts on back of motor. Must mark rear cover of motor so lines up exact for reassebly. Ussually 1/4 inch socket wrench.Seal can be pushed out from back to front with the corrrect size socket and a very light hammer.
Try to factory Jacuzzi seal, they are better than aftermarket.
Coat rubber on seal with light silicone, and press back into place without touching or marring seal face. Best way is use other half of seal (spring piece) to gently but firmly reseat seal. Examine body from rear to make sure seal seats. Reassemble as taken apart, or just take to a qualified service tech at a well established pool/spa place. Kirk

When I changed Pentair Whiperflo motor with new Impeller & Diffuser seals the new motor shaft does not turn. Diffuser is pressing against Impellor not allowing it to rotate. What is wrong ?

Take the Diffuser off and run it if the impeller turns then might be tightening the Diffuser too much, it just needs to not move, doesnt really need a super waterproof seal or anything like that. If it still doesnt turn with the Diffuser off it might have locked up when replacing the Impeller, you can try to turn the impeller manually or remove the cover plate on the back of the moter and turn the shaft manually back there. OOoorr you broke it

I am rebuilding a Northstar pump. I thought I had an o-ring between the diffuser and the impeller ring when disasembling. I don't see the on the schematic however.

The impeller ring moves freely and does not use an o ring. The front of the diffuser does have one. It sounds like they gave you an extra. BTW I have found that Northstar pumps get about 4 years out of their motors. That is about half the average life. I hope you are getting longer than 4 years. If not, it may be worth changing to a different pump.
