Twin Disc MG5061A Lubrication
I need help understanding exactly which lubrication is best for Twin Disc MG5061A gears. The manual has a notation to see the builders plate on the gears for specific lubrication. There is a handwritten notation in the book that says CF-4 30 wt. I know there are detergent and non-detergent oils, straight 30 wt, and so forth. I want to be sure I get the right lubrication. Can anyone help me, please?
