Part of the Case IH Repair Manuals.
Book 2 is the hydraulic volume of the Patriot 3230 and 3330 manual. It covers hydrostatic pump tests, the neutral shunt valve, the park brake circuit, the PWM product pump control valve and troubleshooting charts for the drive, product pump and cylinder circuits. The job stalls when your gauge is teed into the Fa port and you have no spec to read it against. Page 350 gives it: 27 to 29 bar (400 to 420 PSI) at high idle, with the oil at 49 C.
Book 1 carries the specs, maintenance intervals, electrical diagnostics, CAN bus layouts and the Section 4000 engine fault code table. Book 3 covers A/C and ATC codes, the cab, hubs, brakes, booms up to 120 ft and the product pump. The hydraulic and electrical schematics are bound in as fold-outs.
Engine overhaul is not in this manual. It covers engine removal, installation and the isolator mount, and refers you to NEF 6.7L engine manual 84202702 for repairs. The weather sets the spray window, so it helps to have the numbers on the bench before the job starts.
