local resource: deluxe coffee and pasta of sun valley seems to have inherited to abc inventory from the carpiac family. that is a spares trove that is huge and goes back many years. there may be something there to help you. the parts man is sergio.

sidenote: once handled a carton of thirty-six replacement groups for these machines. they were packed in a continuous belt of corrugated cardboard like an ammo belt for a machine gun. it was part of the inventory from the closure of coffee imports.

good luck with the machine,
