How do I change the needle wheel?

[jmckdvm]

I just received the mesh needle wheel for the Orca 250. I'm not sure how the old one comes off. Do you pry it off? (I won't try that until I learn the proper way to remove it). Can somebody please help?
Thank you!

I know this is an old post, but I have the same question?

Ok, you place a slotted screwdriver in the back end of the motor (there is a screw there) and then just unscrew the needle wheel from the shaft. Screw the new needle wheel on while holding the shaft screw with the screw driver.
