Cope did a 3 part series on a race 47re with a set of his race pump gears.

In all my years doing 727's I've only ever seen one set of pump gears break. Not sure of the cause. But it's not very common in my eyes.

Not common at all….. other than lucky me and the original poster I can’t even recall ever reading another thread here on the subject. BUT….. it must happen after all they make a “better” piece.

Over 50 years for me, same findings. One thing that changed was the cut in the converter impeller hub, that helped prevent edge loading on the rotor lugs.

Thanks guys. I have a set on the way.👍 hated to buy them because it sounds like a fluke thing. But I really hate working on small engine cavities with big headers, so I'm not playing roulette🤣
