I sent my form rollers to be recovered and got them back without the MR-110 pin that goes into the end of the shaft, the one with the rounded head that connects to the gear clutch. The roller company says they never saw them. When I prepped the rollers for shipping, I stripped off the gears and springs, but didn’t think to remove the pins; I assumed they were part of the roller shaft and not removable. New ones are available from NA Graphics, but are expensive. Is there some kind of substitute? Are these pins easy to get out, ie, could they have fallen out during transport somewhere? Thanks.
