Yankee tissue machine w. 2nd press going bananas with cylinder speed also axially on both end of DC drive motor like 500%above normal, tacho shaft broke and it gets better, gbx have hi demod signature, at cylinder speed....
But the cylinder brg. levels are only 20% above normal.
Lift the press a bit, it getīs worse, lift of completely it drop 50+% to about
previous normal levels. Logging of applied hydraulic pressure also jumps up and down when full press is on. I suggested swapping cylinder, any other suggestions? Olov
