Hydrolics Help

[NYHowie]

Hi Guys,

I know it has been some time since I have posted but I haven't needed any assistance until now. I have a stahil (spelling) excavator and had a line blow that goes to a piston on the boom. There are rectangle pieces that hold four lines along the boom and I can not figure out how they are mounted. Is there a way to separate it from the boom? Does the line just pass thru this piece or does it come apart somehow?

I am not sure how to post pictures since the photobucket happenings.

Thanks so much in advance.

Denis
