Removing BX hydro pedal

[Jay4200]

The hydro pedal on my BX2200 is a little sticky. The grease fitting isn't working, though I removed and cleared the fitting, so I suspect that it was neglected and grease is hardened up inside the pedal housing. I need to pull the pedal and clean up / regrease the shaft n' collar. That looks easier said than done, however - the pedal doesn't appear to come off easily. I couldn't find anything in the service manual. Any hints?
