Hello all.

I have a us motors asb674 1.5hp motor connected to an aqua haven pump. I just replaced the bearings and one thru bolt with allthread. I checked the motor to make sure it spun free before I reinstalled it. I am stumped. This ia my first pool. Any suggestions on what i should checl next?

Is it heading up to the point of the thermal cutoff safety switch turning off the motor?

The motors tend to get pretty warm, but you should be able to leave your hand on it.
 
Usually that happens due to bearing issues, but I think it can also be cause by degradation of the insulation on the windings which would require a new motor.
Unless you did not put something back together correctly.
Does the shaft spin freely while it is installed in the pump?
 
The thru bolts are the 4 bolts that go from the back plate to the front plate that kind of "squeeze" all the parts together (front plate, body, and back plate)

The one bolt I replaced went thru the magnet. This particular motor has 2 that go thru the magnet and 2 that go on the outside of the magnet

Would be a good time to upgrade to a two speed motor to save $$ on electricity.

Just be sure the motor mates up to your wet end and matches your impeller rating.

Inyopools is a great resource for motors and advice.
