[QUOTE="paull390, post: 65855, member: 8195"] I was successful replacing this bottom hydraulic hose. I wrapped-up the project in January and have been meaning to post details on this site. Here is what I learned. I removed the engine when first starting this project thinking we would have better access. This provided little visibility but ended up being helpful. The access by unbolting the cab and lifting it up was where most of the work was accomplished. We started by removing all the rubber hydraulic lines possible to get to the rubber line we suspected was leaking. We removed the front steel lines on the tilt-lift box. This rubber hydraulic line referred throughout this post (which I call the nightmare line) is at the bottom of the tilt lift box. We had to unbolt the tilt lift box (two bolt go through the box and nuts secure it on the outside body of the skid loader near the rear wheel. At this point we had removed half the metal lines from the tilt lift box (they were all directly above the nightmare line). From the engine compartment(since the engine was removed) we were able to raise the tilt lift box 1 inch or so off the bottom of the skidloader using a long pry bar and a wood block as a fulcrum. Without raising the tilt lift box the nightmare hose will not turn because it comes in contact with the bottom plate of the skidloader. The access panel between the rear and front tires was removed as well as the rear tire. The lines running the hydrostatic motor were removed and a 1/2 ratchet with extensions, a knuckle socket, downsized to 3/8’ was threaded up toward the tilt lift box to a 1-inch crows foot on the nightmare line. After breaking loose the line we used the crows foot and kept the tilt lift box slightly elevated to remove the line. This was a slow painfully process and only turning a little bit each time before sliding the crowsfoot off and repositioning. The line fit so tightly that appeared to me to bind as it was removed. I think the hex end on the nighmare hose rubbed on the housing of the tilt lift box. The new line went on easier and did not seem to bind. It was tighten using the 1-in crows foot and 1/2” ratchet extension, knuckle mentioned above. Everything was reassembled and no leaks to date. [/QUOTE]
