Bleed air from Wagner hydraulic steering system?

I'm having difficulty - loss of full operation with my hydrualic steering system. It is comprised of two wagner pumps upper at upper and lower helms, with an old Benmar AP. (Boat is a 34' CHB trawler)

All has worked fine,usually 5-6 full turns of play on wheel; now no reponse - doesn't tighten up...? Only moves cyclinder at rudder (single) 1/2 of its full extension.

I'm thinking air in system; tried turning left to get it out; tried to break some fittings to see if air would escape... noluck

Is there a prescribed method for flushing or bleeding this system? Any suggestions would be helpful

Thanks
