I shouldn't even be posting because of how upset I am by this situation. I just received my Gen2 magnet upgrade kit today and was really looking forward to "upgrading" my 10 day old Vortech MP40W. So I open the package and there it is my new magnet and shaft. I keep digging but absolutely no instructions whatsoever. At this point I'm thinking no problem how hard can it be...famous last words. My Brand new MP40W pump is not working at all now.....hmm must have been my "lack of knowledge" on how to do the upgrade, but wait I can't find any upgrade instructions ANYWHERE on the internet. I can't even get the wet side apart to reinstall the old parts. The biggest problem, THE NEW SHAFT IS TOO TIGHT ! Now every time I try to start my pump it immediately seperates. How was I supposed to know how to do this upgrade. I figured I had just spent over $400 for this thing and surely they would at least include instructions. I even tried to call customer support before I posted this....guess what ? They're closed. Oh and did I mention that the first time I started my upgraded pump the wet side shot off and landed right in the middle of my clam.....sweeeet. Not happy at all....can anyone help ?
