Impeller screw

Long time lurker first time post.

Forums are awesome but have encountered an issue that has me perplexed.

Went on vacation, neighbor sent me a video message pool pump was very loud. Looked like bearings to me. Ordered bearings and were scheduled for arrival later this week.

Came home and when checking the pump found circuit breaker had tripped. After reseting it, the pump turned on (very loud) and no pressure or suction. Opened skimmer basket to inspect and found the impeller screw had came off. Took motor side off (max e glass II) and reinserted screw. Turned pump back on, pump worked for 5 seconds very loudly and then screw popped off again.

Again Took motor side off to reinsert pool screw but thus time spent more time inspecting and found the impeller free spins when holding shaft with a wrench but will have tension if I use screw driver on back of screw of shaft.

Are the threads in impeller stripped? Are the threads in shaft stripped? What are best option? Buy new motor and impeller or are the threads on the impeller and just need new impeller?

Any help would be appreciated.
 
Remove the impeller and look at the threads inside. May need a flashlight to see. If there are brass shavings, the impeller is stripped. The screw is a "left-hand" thread. It is hard to strip the threads on a motor shaft, either internal or external.
How did the screw end up in the skimmer basket? It would first have had to get past the pump basket and water would have had to reverse through the plumbing.

Thanks I'll try this.

Very difficult to remove impeller. I tried to hold the shaft with a wrench and it still spins freely. It's only when I put a screwdriver onto the bolt on the shaft does it actually hold. But I just can't get enough leverage to remove the impeller.

Sorry I wrote that incorrectly. The impeller screw was not in the basket but in the shaft just on the other side of it.

Thanks for the advice. I will retry and you gave me confidence I don't need a new motor.
 
What bolt are you putting a screwdriver on? Are you holding the shaft with a 7/16" wrench in the back of the motor? If so, and the impeller just spins freely, it may have to be broken off the motor. It can be done, but its not the easiest thing to do. A large pliers can be use to break it up until you get to the brass insert. That can be held with a pliers while a wrench hold the other end of the motor. Don't us a hammer (even when you get frustrated). You will, obviously, need a new impeller. Try to get the number off the back of the existing one.

Just wanted to say thanks guys but it looks like it's going to be a new motor and new impeller. When I disassembled the pump and motor today I found the impeller stripped, a broken governor and a broken single speed switch, in addition to the already identified bearings. While replacing all these components would still be slightly cheaper, at this point it's not worth all the labor.

Might still rebuild it with due time but need to get the pool blue again for the family.

Thanks again
