One part at a time...
I have a berk 12-jg-a pump with an intake. The bowl is shot, impeller shot, and the driveshaft is worn out at the end. I would like to fix the drive shaft. I've heard you can put a sleeve on the end to fix it. Can i make my own sleeve? What is it made out of on a stock berk? I want to fix the intake as well, but the fins on the bottom are corroded a bit. Can I cut them down a bit? I would also like to machine for a shoe and rideplate. Anyone with instructions on how to do this? Thanks in advance.
