This repair started with fluid in the engine room close to the hydraulic pump for the davit. One would think the source was in the engine room, but after hours of ripping out hydraulic lines and pressure testing them, I figured out the source was in the crane itself. In fact it was in the solenoid block area and dripping all the way down 2 decks to the engine room!
After a call to Quicklift Inc. I soon learned there is no service rep in the NYC area. So with some help and no drawings, we disassembled the davit and replaced the bad 1/4″ line. I had to go to a commercial hydraulic shop to get the line made in stainless steel.
The line went bad because the designers made the area that holds the block and control board way too small and this line was forced to bend at a sharp angle. As a note, the control board just kind of sits there in this area also. I think a better solution would have been if they made the area bigger and placed the board in a watertight box. Then they could have thrown some protection around the wires and generally cleaned it up into one run of wires (like a wire harness on your BMW).
