I'm trying to replace the motor for my Pentair LA01N booster pump.  Unfortunately the two lower bolts holding the seal bracket and pump stand to the old motor in place are frozen in place.  I've tried WD-50, and Blaster;  tried muriatic acid hoping it would dissolve any calcium deposits.  I've tapped on the bolts, I've tapped on the socket wrench, but nothing has worked.  Anything else I can try?

Thanks,

Harry

Harry, you can also try to heat the bolts using a hand torch. Sometimes by expanded the metal the bolts will break loose. Other than that the only other thing I can think of is cutting the bolts off and using new ones.
