Part of the New Holland Repair Manuals.
New Holland's REPAIR MANUAL for the D75, D85 and D95 crawler dozers, publication 87364107-NA dated 4/12/2007, printed by CNH America. It is one 1318-page PDF. It covers both the earlier and later serial series for each model, the N6DC and N7DC prefixes.
A dozer that sits with a slow blade or a stored fault code loses you working days. This book gives you the test numbers: 76.8 L/min pump output at 207 bar and 2000 RPM, 203 - 214 bar main relief, and oil at 52 - 79 C before any gauge goes on. Engine overhaul is in a separate Engine Repair Manual, which is not included here.
The chapters are lettered by system, from A Distribution Systems through J Tools and Couplers. The electrical and hydraulic schematics are grouped at the back, so you can go straight to the chapter that matches the fault.
