It's really easy to remove the type wheel from a Model 33, just use a socket wrench to loosen the little nut on the top and it comes right off.

Getting it back on and correctly aligned requires that same socket wrench to repace the nut, but then you have to hold the wheel in the right alignment while you tighten it.  To do this, you need a special tool.  I guess it's technically a 2-pin spanner that reaches in from the side with a split to straddle the socket wrench and two nubs that engage with the two holes in the top of the type wheel, one on each side of the nut.  I didn't have this tool, so I made it from mild steel wire.
