How to Remove the Lever from Houdaille Shocks?

[rogeroadster]

I'm hoping soneone out there can tell me how to remove the lever from my Houdaille shocks. They are unknown year but probably 42-48 fronts and rears with the external adjuster. It looks like the are simply pressed on to a splined shaft but for once I thought I'd ask before I ruined the first one figuring out how to do the rest of them.
