Part of the Case Repair Manuals.
The Case 9020 service manual PDF, OEM part 7-45980, tears this excavator down on paper: 542 pages of factory removal, rebuild, and pressure test procedures running from cylinder head to turntable bearing. Foldout hydraulic and electric schematics trace each circuit from the main pump through the pilot control valves to the swing motor and reduction gearbox. A dedicated troubleshooting section walks the track system, power train, and hydraulics through symptom, cause, and correction, with pressure check points called out. Set track deflection between 2.0 and 2.8 inches (51 to 70 mm), then measure your cylinder block bores against the 102.116 mm service limit before you commit to a reman. Guess at a travel motor and you buy it twice. Pay for this bookmarked, text searchable file once and it stays yours for the working life of the machine.
