Service Bulletin: SB 016.1
Subject: Folding Wing Connecting Arms
Folding wing connecting arms on G-1000 cup machines manufactured between 1961 and 1968 were superseded by a more rugged design. This newer design can be retrofitted to these machines to markedly lengthen the service life of this assembly.
The accompanying sketch shows all the parts required to make the conversion. A slot must be filed in the rod bushings at points marked “X” to allow.clearance for 17471-A and 17472-A connecting arms.
