What could cause a leak in a Polaris pump other than the seal?
Had small leak, replaced the seal. Am still getting small leak from the where the motor shaft enters the rear of the seal assy. I replaced the small o ring on the motor shaft when I replaced the seal. The motor is around 10 yrs old. Can the shaft itself actually wear to the point there is play between shaft and seal and that is why it leaks? Or have I just replaced a bad seal with another bad seal? One thing I noticed on the replacement seal was that the white ceramic piece was not flat. It looked to me like it had a very small chamfer on one side.
