Lower Spray Arm

IT WAS EASY TO DISASSEMBLE EVERYTHING DOWN TO THE IMPELLER. THE BOLT THAT HOLDS THE IMPELLER TO THE MOTOR SHAFT WOULDN'T BUDGE. I TRIED TO SOAK IT WITH PENETRATING OIL AND ATTEMPTED TO LOOSEN IT BY HOLDING THE BROKEN IMPELLER WITH VICE GRIPS. EVERY TIME I TRIED TO LOOSEN IT MORE PIECES WOULD BREAK OFF THE IMPELLER UNTIL ALL THAT WAS LEFT WAS THE MOTOR SHAFT WHICH WAS HEX SHAPED.( A NICE SURPRISE) AT THAT POINT I COULD USE A BOX WRENCH TO HOLD THE SHAFT. THAT'S WHEN THE BOLT BROKE. WHAT TO DO NOW? I FOUND THAT A #14X 3/4 SHEET METAL SCREW THREADED DOWN INTO THE SHAFT NICELY. I INSTALLED THE NEW IMPELLER. PUT SOME SUPER GLUE DOWN IN THE HOLE AND RAN THE SCREW IN. HAVE USED THE WASHER 3 TIMES NOW AND IT STILL HASN'T COME APART. TO BE HONEST, I DON'T EXPECT IT TO LAST TOO LONG, BUT I DON'T FAULT OF THIS SITE. IT WAS JUST BAD LUCK THAT THE BOLT WAS BADLY RUSTED INTO THE SHAFT. I PROBABLY COULD HAVE SAVED THE PROJECT BY TAKING THE WASHER OUT OF THE CABINET AND PULLING THE MOTOR, BUT DECIDED IF I HAD TO GO THROUGH ALL THAT STUFF I'D JUST BUY A NEW WASHER. THANKS, YOUR DRAWINGS WERE GOOD AND THE VIDEOS WERE SOMEWHAT HELPFUL. DAVE
