The quickest and cheapest way to fix a stripped mid shaft.
Let me tell you, this WORKS! This lasted a whole season and its right now sitting in my garage still together. I had to cut the shaft to get the pump out...
Might not be the best long term fix (except for your setup that is still running ) but this proves you could bring some JB weld to a freeride event rather than a backup pump incase you strip a pump
