Have an older AFG burner with a centrifugal pump coupler on a model 68 boiler. I had to pull the pump off and when I put the pump back on everything seemed to go back together smoothly. Slid right in and whole assembly rotates freely. Tried to fire it up and the motor wouldn't run. If I loosen up the pump to the point that the pump is about 1/8" off the mount it will run, but obviously clatters a bit. Tighten up the pump bolts and the motor will stop rotating.
I can't see any interference anywhere and again everything rotates freely with the pump mounting bolts tightened. What the heck did I miss or mess up?
