Ok, I just rebuilt my pumps with remanufactured impellers and wear rings from an aftermarket source. The wear rings were slightly out of round but you'd need a micrometer to tell. The only way I could tell was by hand-spinning the pumps. You could turn them, but it took a lot of work and it hung up about three times per revolution. I called the company that made them and they basically said just to run them and the impellers would cut the ring to fit. I finally got it all assembled today and they engines wouldn't turn over. They would turn, but then they would stall. It was just like when I was trying to turn them by hand only the starter couldn't overcome the part where it hangs up. So, based off an old tip from Dr. Honda, I sprayed them down with WD 40. The starboard one has a strong starter and was already cutting pretty sizable shavings out of the ring. Once I sprayed it down with WD-40, it took off. The port engine has a much weaker starter and I wasn't able to get the same trick to work. It feels like a bad idea to punch the starter 30-40 times in a row like that (it probably turns 1/3 of a revolution each time).
Should I replace these wear rings? Does it hurt them any to cut them down that much (there were literally white pencil shavings coming out of the back of the starboard engine)? Any advice is greatly appreciated.
