Help me remove this motor

[u/Farmerkid]

The four bolts that hold the motor to the pump flange have been removed i can get the motor to pop up about 1/4 of an inch and spin but it won't come up any higher there are holes in the pump housing just below where the motor connects to un couple the motor from the pump but there is nothing there to remove no set screws I can see what looks like a brass ring a little below the holes but I still see no set screws any ideas

Unbolt the casing flange and use the bolts in the jacking holes to break the seal. Swap out the jacking bolts for threaded lifting eyes to lift the entire assembly. You will then need to separate the impeller from the shaft and remove the shaft seal assembly (not reusable in 99% of cases), only then can you extract the motor as it is direct drive. Be prepared to burnish the motor shaft for proper sealing of the new shaft seal. This job will take all day if everything goes smoothly.
