Air in Hydraulic Fluid

[MD83driver]

I replaced all the hoses on my P337H and tried to find any reference to bleeding the hydraulic system and found none in the Service manual. I called Cessna and talked with one of their engineers. His only suggestion that was safe was to cycle the gear until all air was out. So that is what I did, I lost track how many times I cycled it, way more than the 7 times I used a stop watch to check the times. Those I wrote down in the service manual. The problem with the system is that all the lines are dead ended in the actuating cylinders. I guess one has to mix the air with the fluid to get it back to the reservoir so that it can get out. Not like bleeding the brake system. If anyone has any other info, I would be glad to here from them on this subject.
