Covers the New Holland T8.275, T8.300, T8.330, T8.360, T8.390 and T8.420 with the CVT (Auto Command) transmission, PIN ZCRC02586 and above. This is part number 47533595, in English, dated May 2013, for the 9.0 l engine. The same file carries the December 2013 supplement 47533595S1 for tractors with transmission serial AJB0606248 and after.
The book starts with torque tables and fluid capacities. It then works through the engine, CVT, front axle, PTO, brakes, hydraulics, three-point hitch, steering and cab climate. The electrical and fault code section is the biggest part, about 2360 of 4800 pages.
