Whenever you need Vandercook parts contact NA Graphic first., and if they don’t have it contact me (via the contact form in the menu top right). The Vandercook part number for the ink drum bearings is F-760.

The part is called the ink drum. The sound is probably coming from the drum’s bushings, which rotate on the drum’s shaft. The bushings are wood and may have dried out.*

Check the balance of the drum with a spirit level. If level, spray penetrating oil on the bushings. To do this:
1. Unfasten the Drum Box, if present, drum the top shelf of the cabinet.
2. Support the underside of the drum with phone books and/or stacked cardboard.
3. Remove the shaft nut and lock screw on one end.
4. Spray penetrating oil.
5. Replacement bushings are made of Delrin or Oilite.

*Original bushings are made of the wood lignum vitae, also called guayacan or guaiacum, a now endangered tree species indigenous to the Caribbean and the northern coast of South America. It was widely used in manufacturing before the development of polymers, alloys, and composite materials.
