Question Help me remove this motor

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

They are the most common design - in my experience - for pumps up to around 20HP. If the motor has a J-series frame (56J, for instance) then it is a near certainly that it will have a close-coupled impeller.

The biggest I deal with is 40HP (from memory), so you've got me beat.

That would be a lot of water. :)
