I am a graduate student at Ohio University, having issues with our Vandercook 223. Serial no. 8160. I do not have the vocabulary to accurately describe the parts of the press involved, so I have included several videos and pictures to illustrate.
As the cylinder gets to the end of the track – where the registration clamps [gripper bar] disengage [releases]e – it becomes very difficult to move it forward. After the registration clamps [gripper bar] disengage [releases], it moves smoothly, but has the same problem on the return. This problem arose during normal use. Over the course of 2-3 prints, it became increasingly difficult to move past this point. I have checked the track/ gears thoroughly for any obstruction.
One issue which may be related is some slack in the handle/chain inside of the cylinder. I have included a video of this.
Any input would be greatly appreciated! Thanks!

Glad to hear this. Here is your basic care regime:
Before each work day: use a clean rag slightly oiled with SAE 20 to wipe the cylinder bearers, bed bearers,under rails and the circumference of the carriage bearings.
End of session: Make sure that the rollers are disengaged from the oscillator (steel rollers) when not in use.
Weekly: oil the eccentrics with SAE 20 at the hinged-lid cups or beveled holes on the carriage. Use SAE 20.
You can find easily find SAE 20 in the blue and white “3-in-One” brand bottles at most hardware and big box stores.
Paul,
Thanks for your edits, and for your comment. I followed your advice, cleaned and oiled the machine, and it is back up and running. The problem arose so abruptly, I assumed it had to be a more serious issue.
While this is not a common model, which makes more difficult to diagnose online, my experience tells me that cleaning the bearings (wheels) bearers (rails), and oiling at the eccentric holes or cups will make a tremendous difference.
