On my protostar I got it with the bearing and spacers all stuck together. I need a way to get them apart. Also wondering if this has happened to other people?
Take a look around here. I believe there was some recent posts about this as well as some highlighted items in the List of useful modification and maintenance guides section stickied here.
Look before you post… 
Note: When the OP posted this, bcmaddog’s “how to” was like 4 items below his post, thus my answer.
A push-pin always worked for me!
