Re: rebuilding Oberdorfer Pump
Stu - I see that you have the "old-style" impeller cover. As the pump wears, it will score the cover. One of the benefits of the newer style, is that you can flip the cover over, and reinstall the cover...
Again - my last point is that the savings of $20 and having to pull the pump apart (I did the major overhaul and replaced the carbon bearings/bushings), and reassemble, simply wasn't worth it for me to do this again. YMMV.
