Vandercook 4 form rollers wont turn

After much successful use, I had to move my Vandercook 4 proof press. In putting everything back where it is supposed to be, I have encountered a problem (actually several problems, but I fixed the sheared drift pin on the gripper foot lever as well as the sticking and bent grippers). After much scouring, I didn’t see a reference to the newest problem. The form roller that makes contact with the ink drum will not move. When the ink drum is rotating, the roller makes contact, but stays stationery. Thus, no ink can be distributed. I am not sure if this is a consequence of my having removed the cylinder to make the press lighter for moving. Is it possible that I did not index the cylinder properly, so that he gear teeth are misaligned? In general, the press does not look out of alignment, but I could be one or even two teeth off without knowing it. The other possible culprit seems to be the clutch assembly. I had problems inserting the bottom frame form rollers, they did not want to seat properly. The roller clutch trip was engaged, and in the way. I cranked the press a bit, the clutch disengaged and the frame dropped into place, but still no movement as it contacted the ink drum.

Any suggestions would be gratefully accepted, I want to get printing again soon.
