its not the pump itself thats leaking, its the "can".
More to the point, the,,,"can",,, is a seperate critter all together.
it is a discontinued item.
Ohhh, you can buy the innerds new, but you're down to boneyards for the can.
we've tossed around the JB weld or solderin' ideas, but the "can wall" is worn thin from the crank housing rubbin into it and the p/s fluid weakening the surrounding area.
we have also found that there is 3 different style "cans". today we are to disassemble the pump and can, to get the cans part number. Then we shall see if Spaulding actually has our fix.
ill post more about it, once the dust settles
great suggestion about the oven cleaner. a couple squirts around the work area & and wipe with a rag made for a quick clean.
