Bobcat 520 project

/ Bobcat 520 project #21  
Take a look at the parts diagrams for the 520 on Bobcat Parts Online for the hydraulic system, that will give an idea on how it's laid out. You can also get part numbers for seal kits and search; ebay often has seal kits under the OEM numbers. There might be a manual in the files section of the facebook Melroe group, not sure.
There is a component manual for the hydraulic valves in the manual thread on the skidsteer forum. It gets lost in the shuffle so I have a link to it in my sig, just find one of my posts, shouldn't be difficult.

All works and best part no leaks. Rebulit all the cylinders and spools etc. works very well.
Not the easiest project in the world especial with limited parts availability in relation to hydraulics but with some assistance I was able to rebuild everything with new seals etc.
Learned a great deal!
