My 11 year old1/2 hp Pentair pump runs a water feature 12 hours a day. It had difficulty starting a couple of years ago so I replaced the start/run cap and it ran flawlessly for a year. Now it hums but won't start so I replaced the run cap again. This time it didn't fix it, still hums and gets hot. I used to be able to help it start by twisting the shaft with my fingers but not any more. It seems to be binding but I can start it with a crescent wrench and it'll run all day but won't restart. Not sure if it's the bearings since it sounds normal when running. I replaced the bearing seal about five years ago. No apparent leaking.
Do I need a motor replacement? Information from the motor label: Pentair Part 7-177449-03, FR R56Y, Type CX, RPM 3450, 60 Hz , PH 1, 208-230 v, amps 6.0-5.6/11.2, mount horizontal w vent holes down.
If I need a replacement motor, can you recommend something that will fit? Thanks.
