1991–1997 Case 580 Super K / 580SK Construction King Backhoe Loader Tractor Service Manual (P/N 8-17560)

• Coverage is tied to the machine serial range: Case 580 Super K Construction King loader backhoes, P.I.N. JJG0160001 and after. The 1,195-page PDF is a compiled set of Case factory service sections; Form 8-17560 identifies the Engine Removal and Installation section, not the complete manual.
• Engine and fuel-system repair covers radiator and engine removal, torque-converter removal and installation, stall testing, cylinder-head and valve-train work, cylinder-block overhaul, lubrication and cooling systems, turbocharger service and failure analysis, injector testing, and injection-pump timing.
• Configuration-specific procedures separate the CAV and Bosch injection-pump sections; the factory TOC identifies them as 4-390 and 4T-390 applications. Other splits include naturally aspirated versus turbocharged test data, Eaton versus Danfoss steering control valves, and 2WD versus 4WD front-axle service.
• Powertrain and brake sections cover transaxle and converter-housing removal, hydraulic PTO repair, rear axles and planetaries, transfer gearbox, differential lock, forward/reverse valve, charging pump, output shaft, and internal transmission service. Brake coverage adds the parking brake, disc brakes, master cylinder repair, and bleeding.
• Hydraulic diagnosis and component repair covers all-circuit and single-circuit fault isolation, relief-valve and pump flow tests, plus hydraulic-system cleaning and water flushing. Repair sections address the pump, loader/backhoe/three-point-hitch control valves, cylinders, swing sequence valve, and double selector valve.
• Electrical, A/C, and mounted-equipment coverage provides circuit test charts, cab/canopy harness data, starter, alternator, and instrument-cluster repair, plus A/C pressure diagnosis, system evacuation and charging, and component replacement. Mounted-equipment sections add return-to-dig and antirollback setup, loader-frame and backhoe-structure service, ROPS, three-point hitch, and standard and suspension seats.

What the Factory Sections Actually Cover

The engine material goes well beyond tune-up data. Cylinder-head procedures cover removal, disassembly, resurfacing checks, valve-guide and valve-seat replacement, valve refacing, rocker-arm service, installation, top-center location, valve-clearance adjustment, and thermostat work. The block chapter adds front and rear oil seals and wear sleeves, piston and rod inspection, cylinder-block reconditioning, main-bearing replacement without removing the crankshaft, crankshaft and camshaft service, flywheel and ring-gear work, and a crankcase-pressure test.

Variant control is explicit. The cylinder-head specifications distinguish U.S.-built, Darlington-built, and Neuss-built engines by engine serial break and injector-nozzle configuration. Electrical coverage separates the standard and optional battery arrangements and the 65-amp and 95-amp alternator systems. Steering repair is divided between Eaton and Danfoss units, while axle procedures are split between two-wheel-drive and four-wheel-drive machines. PTO-equipped machines also receive their own clutch, valve, shaft, pressure-test, and removal information.

The powertrain section combines internal repair with operational diagnosis. Its transmission troubleshooting charts address a machine that will not move, loss of power, overheated transmission oil, rapid clutch or brake-disc wear, and pinion-shaft failure. Related chapters cover clutch-pressure checks, charging-pump output, converter inlet and outlet flow, brake-cooling flow, lubrication flow, gear-contact checks, bearing preload, end play, and shift-linkage adjustment. Hydraulic diagnosis is organized the same way, separating problems that affect every circuit from faults isolated to one cylinder or control-valve section.

Drawings, Tools, and Service Reference Data

Electrical examples include Starting, Charging, and Instrument Cluster Circuits plus Cab Harness and Canopy Harness layouts; steering has its own schematic with component views. Powertrain and hydraulic examples include the Schematic of Transmission Hydraulic System, Loader Backhoe Schematic, and Loader Three Point Hitch Schematic. Exploded views and cross sections support the PTO clutch and valve, loader and backhoe control valves, hydraulic pump, swing sequence valve, cylinders, loader frame, backhoe structures, and three-point hitch.

Factory-tool callouts are specific to the work. Engine removal uses the CAS-1690 rotation tool and CAS-2081 alignment tool. Hydraulic tests call for the CAS-1804/CAS-10111 pressure fitting kit and CAS-10280 flowmeter, while PTO and transmission work uses the CAS-1992 clutch spring compressor. The hydraulic-cleaning section also identifies the CAS-10162A portable filter and CAS-10508 fitting kit. Reference pages provide standard and component-specific torque tables, approved fluids and capacities, pressure and flow specifications, wear limits, clearances, preload and end-play data, electrical test values, adjustment dimensions, and special tightening sequences.

Several cautions are easy to miss during repair. The cylinder-head chapter warns that allowing an injector to rotate in its bore can damage the head, and its identification marks determine the correct head-gasket specification after resurfacing. The turbocharger section calls for lubrication before operation; a dry start or immediate loading can damage the bearings. The loader-control-valve chapter requires each section to be numbered, the inter-section O-rings held in place, and the original shim sequence restored. Losing that order during teardown risks leakage and incorrect valve alignment.

Support raised loader or backhoe structures, relieve stored hydraulic pressure, keep clear of injector test spray, and follow the refrigerant-handling instructions before opening an A/C circuit. The ROPS chapter treats a damaged cab or canopy as a replacement item rather than a weld-or-straighten repair. The content is factory service information for diagnosis and repair; it is not a parts catalog or operator's manual.
