Has anyone taken apart a SPAL fan?

I have two spal fans that are not working (not voltage dependant) and before I take them apart, I want to know if anyone has experience opening them.

Thanks

 

Are you opening the motors? I may have the instructions for them, I could look and post them if that will help.

 

YES. I just took it off the shroud today and took the blade off. The thing looks very well sealed so I am not sure how to get the motor apart yet. Any help would be appreciated!!
