We need a good 2nd source for Riso parts for Riso's we service. Today we need part # 61281602003 which is a gear for a RZ220 that Riso charges a $1.90 for it. We are a Riso dealer many mach's in the field but we have to make a min order when we order from Riso. Call us @ 716-832-4950 and speak to Ward and we may start getting odd parts from you.
