Case 580 Super E Construction King Backhoe Loader Manual Collection (1985–1988)

The service manual provides workshop repair procedures. The separate brochure adds equipment specifications, working dimensions, and Dig Depth and Lift Capacity charts.

Drivetrain coverage limits: The transaxle/differential-lock and self-adjusting differential-brake sections are explicitly labeled for machines with turbocharged engines. For naturally aspirated engines, the transfer-gearbox chapter refers mainshaft adjustment to Section 6214, which is not included. Torque-converter coverage addresses removal and replacement; the converter itself is not repairable.

PDF Search, Bookmarks and Diagram Detail

Search and diagram access: The service PDF is partly searchable, with an OCR text layer and 67 embedded bookmarks. Wiring pages and some illustrated pages lack searchable text. The brochure has neither text search nor bookmarks. Small wiring labels require zooming, and watermarks cross some diagram areas.

The ZIP download contains 2 printable PDFs totaling 1,365 pages. This total already includes one added cover page and two front contents pages in the service PDF.

Engine, Power Shuttle and Hydraulic Repair

The following selected coverage highlights outline the repair content rather than reproduce the full contents list; additional topics include seat assemblies and decal placement.

• Engine repair: Step-by-step procedures for engine removal, cylinder-head service, valve-train inspection, cylinder-block repair, and crankshaft, piston, bearing, and seal work.

• Fuel system: Injection-pump removal, installation and timing, drive-gear service, fuel-system air removal, and injector testing, cleaning and adjustment.

• Hydraulic diagnosis: Engine stall tests, flowmeter checks, relief-valve pressure tests, pump inspection, cylinder repair, and control-valve disassembly and assembly.

• Power train: Power-shuttle removal and rebuild, clutch and charging-pump service, transaxle removal, differential-lock procedures, and four-wheel-drive transfer-gearbox repair.

• Steering and brakes: Steering-control-valve overhaul, steering-cylinder service, two- and four-wheel-drive front-axle work, master-cylinder repair, and configuration-specific differential-brake procedures.

• Electrical systems: Starting- and charging-circuit troubleshooting, battery tests, starter and alternator repair, instrument checks, and chassis, cab and canopy wiring diagrams.

• Mounted equipment: Loader linkage adjustment, backhoe and Extendahoe disassembly, dipper-extension wear-strip replacement, ROPS cab/canopy removal, and air-conditioning diagnosis and service.

This manual suits service technicians equipped for pressure testing, injector testing, precision measurement, and handling heavy machine assemblies.

Engine Inspection and Fuel-System Work

The engine coverage centers on the Case 4-390 diesel, with cylinder measurements, valve-seat contact-pattern charts, bearing inspection limits, and component-specific tightening references. Lubrication and cooling chapters cover oil-pump inspection, water-pump service and thermostat testing.

Shared engine sections also contain 4T-390 procedures, turbocharger service and turbocharger failure analysis; these do not establish a turbocharged engine option for every listed machine.

Injector-removal cautions identify cylinder-head damage caused by allowing an injector to rotate in its bore.

Hydraulic Fault Isolation and Valve Variants

Stall-test results help distinguish engine, torque-converter/power-shuttle and hydraulic causes of poor performance before a major component is removed. Flowmeter check sheets then support comparison of pump output with individual circuit performance.

Separate chapters address J I Case and Parker Hannifin loader control valves, along with backhoe and stabilizer valves. Hydraulic diagrams distinguish loader circuits and backhoes with foot-swing or hand-swing controls.

The hydraulic test cautions explain how a test connection that bypasses the steering relief valve can expose steering components to damage.

Power-Shuttle Rebuild and Component Identification

Internal shuttle procedures cover forward and reverse clutch components, the charging pump, control valve and output-shaft assembly. The flex-plate installation section specifies centering tool CAS-1153A.

Serial-break illustrations distinguish component arrangements in the included transaxle, transfer-gearbox and brake sections. Match those sections to the engine configuration and transmission serial number before selecting a procedure.

Backhoe, Loader and Electrical Details

Backhoe instructions extend to swing-tower bushings, bearing washers, boom and dipper removal, extension guide blocks, and bucket cutting edges. Loader material includes return-to-dig and antirollback adjustments.

Chassis and ROPS cab wiring diagrams distinguish magnetic-switch and relay-equipped machines. The Instrument Cluster diagram and wire-number/color tables support circuit tracing.

Working on a backhoe loader involves raised equipment, pressurized hydraulic circuits, rotating machinery, and heavy assemblies. Review the publication’s introductory safety information before beginning repair work, and secure the machine appropriately before disconnecting hydraulic, drivetrain, or electrical components.

Examples of Valve-Clearance and Oil-Pressure Data

For the Case 4-390, cold rocker-arm-to-valve clearance is specified as 0.010 inch (0.254 mm) for intake valves and 0.020 inch (0.508 mm) for exhaust valves. Cylinder-position diagrams accompany the adjustment procedure.

Engine lubrication specifications give an oil-pressure range of 42–54 psi with the engine warm and running at rated speed.
