I'm pretty sure that chassis has a cover over the bottom. There is a good chance that the parts will be laying loose in the bottom.

It's a pretty close tolerance between the inner and outer knob but I don't think you can get to from the backside as the dial is in the way. I suppose if you were able to lay the cabinet on it's back (knobs facing up) you could get some lub between the two dial knobs. If you are curious about how they come off your 630 have the same knob set up. As Ron eluded to the knobs can be a little difficult to get off as you are remove two at once, pull twice as hard. If you have trouble getting a good grip some use a loop of twine around the outer knob (between the knob and cabinet) to pull on. You'll want to be careful not to get any thing on the dial material as it could remove the print from it. There are replacements available @ $30 or so.
