I replaced my Challenger pump Mod: B2854 last summer. When I opened my pool this year the shaft seal was leaking so I replaced the seal. However, the shaft seal is leaking again? Does anyone know what causes this? I haven't run my pump since it started leaking, but want the kids to be able to use the pool. I just hate to replace the seal again only to have the same issue. 

When I did go to change out the shaft seal, I noticed that it was badly damaged. Also, there was some minor pitting on the pump shaft that I used emory cloth to smooth out. I followed all guidelines when replacing the seal, including watching numerous videos available for it.


Just don't understand it. I hope someone else has had this same issue and can point me in the right direction. 


Great forum! Thanks!
