Military doesn't have the U500 in its inventory. The -20 reference came from my maintenance officer (S4) days in the 82nd.

I have the owner's manual but its German to English translation leaves a lot to be desired. It really doesn't offer me any info but I do have an excellent bodybuilder CD with CAD drawings and location layout of all hydraulic lines, etc.
Thanks for the leads on locating shop manuals.
