This 216-page Fiat 780-780 DT, 880-880 DT Workshop Manual (OEM #603.54.201) covers both tractor variants, from the 780 to the 880. Inside you get wiring diagrams for the electrical system, hydraulic schematics for the Lift Unit, plus torque figure tables and teardown procedures for the engine, gearbox, and final drives. No more guessing whether that clearance spec applies to your 780 or the 880 DT variant. This searchable, bookmarked PDF opens on your phone or tablet, so you can jump straight to Power Train or Front Axle - Steering and start turning wrenches instead of flipping through a stack of paper in the shop.
