I've been saying for years that the stainless shafts are too soft. I'm the sort of guy who would rather have an ordinary looking car going reliably than a pretty one stopped.
I have been toying with the idea of making new pumps with ball races front and back and a ceramic seal so NOTHING rubs the shaft. (Even a stainless shaft would last that way.) Not sure it can be done economically though as new bodies would have to be cast. Henry didn't use quite enough metal to retro fit an original. Sand casting is slow and prone to variances while using a die means a big expense to make the die. I'd have so much money in the die that I'd have to make (and sell) many thousands of them to break even, then there is the problem of marketing etc in the US - so far away. I've made 3 for myself and no failures yet after lots of miles.
