Good afternoon, i hope the thread is in the right place 
I've got an issue with my bennet flap pump.
When the boat was stopped 5 years ago flaps were working properly.
Now that i'm rebuilding the boat i noted that flap is not working anymore , it seams that motor shaft is blocked.
Does enyone know how to take in part this motor? Between motor and pump it seams there is a white glue and i can not open it.
Thanks everyone will help
