Welcome to the Forum!

Please listen to Mark!!

The Northstar is something of a "lemon" However, I've changed out a few dozen motors and will help you with the 'nuts and bolts' of the changeout.

Pick up a new shaft seal assembly (SPX4000SA2), trying to reuse one, no matter it's age is a very BAD idea.

My participation here is lower than I'd like, due to a computer hacker and a job I just started which has 'grueling' hours. I'll check in at least on the weekends and will assist you with the motor swap.
