Hey Folks, I'm working on a Grove 2530D LX Mobile Crane. This picture show the Hydraulic Manifold that powers the hoist' wire rope drum. It was leaking so I cracked it open, it opened in four pieces like four slices of bread and had O-rings for each port meeting the adjacent piece. So I replaced all of the O-Rings and put it back together. When I went to use the hoist the hoist wouldn't work. All of the other functions on the Crane worked. Helpful advice is welcomed!
