This is the factory repair manual for the Cat 299D and 299D XHP compact track loaders and the 272D and 272D XHP skid steers, 2015-2023, all in one bundle. It covers the machine end to end: hydrostatic drive and final drives, load-sensing hydraulic system with full pressure testing and adjusting procedures, the electrohydraulic joystick controls, engine teardown, undercarriage, and complete electrical and hydraulic schematics. These D-series machines are electronic, so the manual pairs monitor diagnostics with real gauge work - actual relief settings, charge pressures, cycle times, and drift limits with tolerances. If you run a standard-flow machine or a High Flow XPS/XHP unit, both spec sets are in here. This is what the dealer tech reads before quoting you a repair.
