Part of the Case IH Repair Manuals.
Common rail and EGR diagnostics are the hardest work on a Farmall 35C or 40C. The fault code chapters here go circuit by circuit through rail pressure, injectors, crank and cam signals, DPF overload and water in fuel.
The rest of the book covers the 3-cylinder turbo diesel, clutch, 12x12 mechanical transmission and HST, four-wheel drive, both axles, rear and mid PTO, and brakes. It also covers open-center hydraulics, the three-point hitch, power steering and cab climate control. Electrical schematic sheets for the 40C Cab and the 35C ROPS come with connector face diagrams and pin tables.
Pin down the failed part first, and you order the right one the first time and get back in the field before the weather turns.
