Hello guys —Happy holidays! I installed a long lost taper pin for the rider rollers shaft on my no.4 and realized that the MR-113 Tie Rods where the M-123 Rider Rollers go, are definitely twisted or bent so they make the installation of the pin a very tight fit and makes the frame sit twisted […]

No. 4 grinding chatter
We have a No. 4 who is the work-horse of our print shop (at MCBA). In recent weeks, it has started an awful chattering noise, that continues to get worse. At first I thought it was the gear and the clutch on the form rollers that were rubbing together. But on closer inspection the gear […]
MoreRoller Change – Stiff Front Roller
I changed my rollers for my SP15 and I’m finding that the front roller is stiff, it doesn’t move as freely as before. It doesn’t seem to have a problem when it is inking. I didn’t notice this until I went to go and clean up the press.

Hi everyone, I recently acquired a Universal 1 and have a couple questions related to maintenance. I have been keeping the rollers raised by raising the lever for that purpose when the press is not in use, but wasn’t sure if I also needed to raise the oscillator and a single rider fully away from […]

MoreGummy SP-20 rollers
After acquiring, I did a thorough clean-up the ink rollers on my SP-20. That was months ago, and they have remained somewhat gummy, tacky to the touch. At first I thought it was due to the humidity, but that’s no longer an issue. They were pretty crudded up & I gave them a good scrubbing […]
