Yes, just a little flat head screw drive to pop the black bit out of the white bit.
:eyebrow: I actually forgot to pop some grease in there. Got a little distracted by some meddling kids ripping my gutter downpipe off !! :spank:
Good job Adam, when I had mine off I thought I would destroy it popping it apart. I'm delighted that it has been proven that with some ingenuity it is completely serviceable. Thanks for posting in the relevant section and good luck with the job hunt.
