twin disc MG506

[jmencel]

I'm about to change the transmission oil on my twin disc transmissions (Cat 3208). I am unable to read the amount of oil and the oil viscosity on the transmission plates. I believe the oil viscosity is straight 40 weight. Can anyone confirm as indicate likely amount required as well? Thanks. John

40 weight straight grade is what you run. You may be able to find the fill capacity on boatdiesel.com, or someone may know it there. They have a lot of specs posted for all kinds of diesel and marine gears.

3-4 quarts if I remember right. Depending on the cooler setup. You check the level with it running in neutral.
