They are not dramatically complex. Take good pictures and disassemble the stack of valves.
Be careful to find the Orings to use new where ever they are. CaseIH will have the Orings.
If the lever is frozen it will not move at all. If thespool valve is frozen the lever may move a tiny bit. If the spool is stuck it may be rusted in the bore such that even if freed, it would leak. Taking it apart is the only way to do it as force will break the lever. Jim
