Part of the Case Repair Manuals.
The D-179 won't fire after a filter change, or the hydraulic oil level keeps dropping and you can't see where it's going. This factory Case service manual covers the 380B industrial tractor. Many sections are shared with the Case 85 Series ag tractors.
It covers the engine, the fuel system with the Bosch VE and VA injection pumps, electrical, steering and front axle, power train, brakes and hydraulics. Separate chapters explain how the hydrostatic steering and the tractor hydraulic system work.
Most jobs don't stall on the wrenching. They stall with the head torqued to the second stage and nobody sure of the final figure. The specs are in the book, down to injector opening pressure and pump timing. Look up the number, finish the job and get back in the field.
