Can anyone steer me in the right direction how to remove the ram from a vertical pillar stabiliser??
Welcome to HEF Priemsy ! That stabilizer arrangement is not found on 580's in North America very often. Mostly in Europe and Australia. There is an HEF member that has the user name Alrman. He is an expert with anything made by Case. He owns a repair business in Au. Send him an email and ask him to read this thread. I"m sure he will help you with any questions you have about those vertical outriggers. Here is a link to his website. http://www.alrearthrep.com.au/
