Greetings! I’m looking for advice regarding a retaining screw that has partially worked its way out of the bearing block on the operator side of the front form roller on our SP-15. Any suggestions for best practices in terms of returning the screw to its proper location? It doesn’t seem to want to budge… in any direction! Many thanks in advance.
You should also get some Nyliners in there that have the flange on the outside. There should be one on the inside between the block and the roller core and one here between the block and the screw- they work in pairs. If you don’t, the head will slowly cut right through the side of the block as you use the press.
If the threads on the screw are too worn you can replace it with one from a hardware store. The head wont be the same and smaller. Use a round head with a washer behind it. Otherwise it’s available from NA Graphics.
Thanks, Paul! I’ll give the threads a good cleaning and go from there. Much appreciated!
The threads on the screw may be plugged with grime and a bit worn. The interior threads on the core may be clogged with rust, grime and/or rubber from manufacturing.
Clean the screw threads and inspect for wear. Lightly lubricate the threads and use a 1/4-28 thread cutting die if needed. If you don’t have a tap and die set, dies can be purchased individually and a hardware store.
The interior threads on the core may be clogged with rust, grime and/or rubber from manufacturing. Use a 1/4-28 thread chaser, lightly lubricated, to clear the threads of debris.
