I have done the search thing for a while and I am left with only one question. I understand that when you tap the side of the box you get high pressure to both hoses (only one at a time ofcourse) Is the same thing happening when you tap the front cover and top cover? (Saginaw box) Any info on how it works this way would be great. It would save some trouble.:) :D

The two ways net the same thing. You turn one way and get fluid to flow to one side of the piston(in the box), turn the other way and it flows the other way. I like to use the front and top cover, this allows you to replace the box, if it should fail. With out having to go thru the tapping of the box. You can just replace the covers with your already taped ones. Tapping into the box it's self is a cleaner look.

Thanks a lot. That is exactly what I was looking for. I figured that is how it would have to work but wanted to make sure before I did it. I know what next weekends project will be now!!:D
