Part of the Case Repair Manuals.
The 650L Tier 3 runs left and right hydrostatic pumps and motors under a drivetrain controller that talks CAN with the engine controller. When that link drops, the crawler will not move. This Case service manual, part number 84276960, works through the fault codes one controller at a time. It also covers hydraulic tests, final drives, brakes, tracks, cab, A/C, blade and ripper.
When the machine is down on a job and there is nobody to call, you need the numbers in front of you. That means relief pressures, pump flow at 2000 RPM, final drive and track torques, fill capacities, and fold-out electrical and hydraulic schematics. This is the October 2009 CNH issue, and it replaces 84260831.
