CASE 580E Super Loader Backhoe Factory Service Manual (P/N 8-41701)

• Coverage and document identity: J.I. Case factory service manual for the CASE 580 Super E (580E) Loader Backhoe, supplied as a 1,357-page PDF. Main Form No. 8-41701, including revisions 8-41701-R1 and 8-41701-R2.
• Engine repair sections cover the 4-390 and turbocharged 4T-390, including engine and power-shuttle removal, cylinder-head and valve-train work, block, crankshaft and camshaft service, lubrication and cooling systems, injection-pump timing, injector testing, and turbocharger overhaul and failure analysis.
• Powertrain coverage follows the power shuttle and torque converter through pressure testing, removal, internal disassembly, clutch and pump inspection, reassembly, and operational checks, then continues into the transaxle, differential lock, transfer gearbox, driveshaft, and separate 2WD and 4WD front axles.
• Hydraulic repair content includes system diagrams, flowmeter tests, main and circuit relief-valve checks, pump failure diagnosis, system cleaning, separate J.I. Case and Parker Hannifin loader-control-valve procedures, backhoe and stabilizer valves, three-point-hitch controls, and cylinder service.
• Electrical and steering sections provide voltage-drop testing, charging and starting troubleshooting, chassis and ROPS wiring for magnetic-switch and relay configurations, instrument-cluster circuits, steering-valve and steering-column overhaul, steering-cylinder repair, and relief-valve testing.
• Brake and chassis chapters distinguish pre- and post-transmission serial 16270319 self-adjusting differential brake hardware, then cover loader and backhoe removal, swing-tower and extendable-dipper service, antirollback and return-to-dig linkage, ROPS cab and canopy work, air conditioning, seats, and optional three-point-hitch equipment.

Factory Repair Coverage

This is the shop service manual for the 580 Super E, not a general operating handbook. It combines machine-identification and maintenance data with factory repair procedures for removal, teardown, inspection, assembly, adjustment, pressure testing, and final checks. The identification page maps the PIN and component serial locations for the engine, transaxle, power shuttle, front drive axle, backhoe, ROPS, and buckets. That information matters whenever a repair procedure changes by component build.

The engine chapters center on the four-cylinder, 3.92-liter Case diesel in naturally aspirated 4-390 and turbocharged 4T-390 form. Coverage goes well beyond tune-up data: torque-converter and hydraulic stall tests, engine and power-shuttle removal, front-engine-support centering, cylinder-head removal and disassembly, valve-guide and valve-seat replacement, dye-pattern diagnosis, rocker-arm adjustment, block reconditioning, crankshaft and main-bearing work, camshaft service, oil-pump repair, cooling-system repair, fuel-injection timing, injector spray testing, and turbocharger inspection are all treated as factory shop operations. The specification material also distinguishes engine builds before and at or after engine serial 44117591.

Drivetrain depth is equally specific. Pressure-gauge check sheets isolate power-shuttle clutch and cooling circuits before teardown. The manual then covers torque-converter and flex-plate service, forward-clutch and charging-pump work, pinion-cage and output-shaft assemblies, transaxle removal, differential bearing preload, ring-and-pinion backlash, differential-lock repair, the 4WD transfer gearbox, and both front-axle designs. Brake repair is divided around transmission serial 16270319, with separate hydraulic-cylinder, actuator, housing, and 2WD/4WD hand-brake procedures to keep early and later hardware from being mixed.

Hydraulic diagnosis is organized around the actual 580 Super E circuits. Named test sections cover the loader side of the pump, loader circuits and the main relief valve, backhoe circuits, the steering side of the pump, hand-pump testing of circuit relief valves, and main-relief pressure checks. The system-cleaning chapter identifies the CAS-10162A portable filter and CAS-10508 fitting kit, while the fuel and engine sections show tools such as the CAS-1745 dial indicator, CAS-1690 engine turn-over tool, CAS-1691 gear puller, and CAS-10240 valve spring compressor.

Schematics, Specifications, and Shop References

The diagram set is broader than a few engine illustrations. Useful examples include the Product Identification Number and Serial Numbers locator, chassis wiring diagrams for magnetic-switch and relay machines, ROPS cab wiring, the Diagram of Instrument Cluster, the Hydraulic Diagram for Loader, backhoe hydraulic diagrams for foot-swing and hand-swing controls, three-point-hitch hydraulic diagrams, and the air-conditioning system diagram with pressure-temperature troubleshooting charts. Exploded views support the air cleaner, radiator, power shuttle, front axle, driveshaft, loader, seat suspension, three-point hitch, and backhoe assemblies.

Reference data covers maintenance intervals, approved fluids, heater and non-heater capacities, component-specific torque tables, hydraulic pressure and flow tests, clutch and gear clearances, bearing preload and backlash, wear limits, valve and injection settings, electrical specifications, and tire and wheel data. Routine service charts sometimes refer to the operator's manual for basic owner-level tasks; repair, overhaul, test, and adjustment procedures remain the focus of this publication.

A few cautions show why the factory sequence matters. The injector section warns that allowing an injector to rotate in the cylinder-head bore can damage the head. During power-shuttle installation, the torque-converter splines and hub tangs must engage correctly before the assembly is seated; misalignment puts the converter hub and pump-drive components at risk. Turbocharger failure-analysis plates connect coked housings and scored bearings with dirty oil, restricted oil return, excessive heat, or loose compressor hardware. Replacing a failed turbo without correcting the cause risks another failure.

Before hydraulic, loader, or backhoe repair, lower the attachment or install the specified lift-cylinder support, shut the engine down, and relieve trapped pressure before opening a line.
