Speedometer tips?

In my recently acquired '55 400, the speedometer cable was broken at the trans and as it turns out it's due to the speedometer head turning very stiffly. It doesn't make noise, just takes considerable effort to turn, but does turn and operate, at least until the next cable breaks. I would think it should turn freely.

Any tips on speedometer clean and lube, which I assume requires removal?
