Checked with Octavio regarding the solenoid. When the solenoid on the Puma CNC was broken, in order to keep the production,the one on the Hyundai CNC was move to the Puma CNC (cannibalized). Now, Octavio received the solenoid for the Puma CNC and will be able to put the solenoid back on the Hyundai CNC. After the current threading job is done, Octavio will install the solelnoids.

However, the two solenoids are not identical on physical shape.
