215 Vibrator Issues

The vibrator has been pausing and jumping, so last night I took it apart to see if anything was broken on the crescent or worm gear. Didn’t find any problems, but I cleaned everything and greased it thoroughly before reassembly. Tried it this morning with no ink and it still hesitates at some points in its travel. I checked the form rollers and blocks and all seems to be normal. Any ideas what I need to look for to fix?

As Fritz commented in a previous post. The extra diameter is already factored in. https://vandercookpress.info/vanderblog/2011/02/recasting-rollers/

If it’s not wear on your worm or crescent, then it’s the rollers. You may recall that I checked the diameter which averaged 2.43” (the spec is 2.5” +/- .015”). Also the durometer read A35, too hard (the spec is A20).
