The way it shows in the manual is correct based on what I can find on this pump. The shaft seal will be snug, but it shouldn't be extremely tight though. The 2 pieces you replaced should have taken care of any leak between the pump housing and the motor. It could be the seal plate has warped some and now allowing the seal to do its job.

Some of the shafts seals have a particular direction they have to go on the shaft. For this one, I do not have any installation notes to know for sure but that is a possibility.

Thank you for using Manage My Life!

Q:

How do I remove shaft seal (ceramic) from seal plate?

A:

Getting good directions makes any repair go so much easier. While you wait for the expert to review your model and respond I attached two links below that may help. The first is the owner's manual and the second is the link to the schematics at Sears Parts Direct for your pump. Hope some of this information proves helpful.

Thank you for your question.

I can understand the difficultly of trying to remove the ceramic half of the shaft seal from the housing.

If you are replacing the seal with a new one do not worry about damaging the seal.

If you want to remove the seal to put it in a new housing you can use a very small thin flat bladed screw driver and work it in along the rubber boot of the seal and slide the tip of the screw driver around the edge to remove any rust build up and then carefully begin to gently pry the seal out, with out breaking the ceramic surface of the seal and working around and around until you can get it worked up and out.

I hope this process will work for you like it works for me.

Thank you for using Manage My Life.
