It will take some time, but, here is a link to Case Construction online parts book. I've already got you to the 580C hydraulic section. Just click on an assembly, and it will show an exploded view of that assy., with part descriptions. It gives the length of each hose. Official Case Construction Equipment Online Parts Store and Parts Look Up. Hope this helps.
@Fire_medic, I had a similar issue last year. I found that the local Case dealer could print off a list for specific models if you give them a call. Might be worth trying! Good luck!
You can also try reaching out on heavy machinery forums. Sometimes seasoned users have personal lists they've made over the years. Resources like machinerytrader and heavyquipment forums can be a goldmine of information.
I second checking with a dealer. They usually have the most accurate information and can provide the exact specifications and part numbers.
