Part of the New Holland Repair Manuals.
On the New Holland EH215 crawler excavator, pump control, boom and arm flow merging, recirculation, travel straight and swing priority all depend on sensors and proportional valves. This book covers self diagnosis and service diagnosis for that system, plus sensor and proportional valve checks.
The rest of the book has the colour-coded hydraulic circuit diagram and three electrical circuit diagram sheets. It also has the performance inspection chart and the removal and teardown of the attachments, cylinders, upper structure and travel system. The Mitsubishi 6D34-T engine shop manual is in there too. This is CNH America Form Number 6-75780NA, issued January 2004.
