hi i just installed a new ust1102 motor to replace my old hayward super 2 pump , 115v , 1hp, sf 1.5, but motor is still making rattling noise, could i possibly have a bad impeller, it looked fine when i installed it, also replaced all motor seals and gaskets in housing, if so what is the replacement impeller # because the descriptions on your parts page are confusing me with the full hp and the up hp difference, the model # of my old motor is
K48L2N104 if this helps
