IMM 8/97

Does anyone know how to retrofit older mechanical knockout machines to hydraulic ejection? How do you tie it in with the rest of the machines hydraulics and controls?

Yes, I just converted a 1967 Newbury with mechanical knockout to hydraulic knockout. You have to add a separate hydraulic circuit and a separate electrical circuit to the machine. The electrical has to be tied in with the safeties. A two-stage pump is added in place of a single-stage pump for the hydraulic ejection system.
