Got a bad squeal on the SP-15. Can’t figure out where the noise is coming from. Suspect that the back roller core is defective and the bearer is not holding it correctly. I think we need a new roller/core. Anyway, in printing the oscillating roller squeals badly. Just started doing this today. Any thoughts? Thanks.

  1. Are the roller end screws chewing into the blocks? Vandercook used Nyliners with a flange only on one side on the SP-15. It is better to use a pair of Nyliners so you can have a flange on the inside and the outside to protect from metal on metal contact. This will protect your cores, blocks and end screws.
