Case 580 Super E Construction King Backhoe Loader Service & Repair Manual (P/N 8-41700, 8-41701, 8-41702, 8-24161)

• Covers 1985–1988 Case 580 Super E Construction King backhoe loaders, including the standard 14-foot backhoe and the 14- to 18-foot Extendahoe configuration.
• Documents Case 4-390 diesel engine repair, with cylinder-head service, valve-train maintenance, turbocharger failure analysis, injection-pump timing, and injector specifications.
• Provides hydraulic-pump maintenance, pump-output testing, system diagnosis, and engine stall-test procedures used to separate hydraulic faults from engine-performance problems.
• Details power-shuttle transmission removal and rebuild work, differential-lock operation, and four-wheel-drive front-axle service, including Super E torque data that differs from earlier models.
• Includes wiring diagrams, battery and alternator troubleshooting, electrical test information, and 123 illustrated procedural sequences covering component removal, testing, and fault isolation.
• Supplied as a 1,300-page PDF covering Case Form Nos. 8-41700, 8-41701, 8-41702, 8-24161, and 8-24621, revised July 1985.

Factory Repair Coverage

This factory service publication is written for full shop repair work on the 580 Super E rather than routine operator-level maintenance alone. The sections are organized around individual machine systems, giving technicians, independent repair shops, and experienced owners the reference material needed for removal, inspection, disassembly, repair, reassembly, adjustment, and final testing.

The engine coverage centers on the Case 4-390 diesel. It addresses cylinder-head assembly work, valve-train inspection and maintenance, and the checks used when diagnosing turbocharger problems. Fuel-system material covers injection-pump timing and injector specifications, while the related engine data provides component-specific torque information and cooling-system capacity references, including data for machines equipped with a heater.

These sections are useful during both complete engine repair and targeted diagnosis. A technician can follow the factory references for the affected assembly without relying on specifications carried over from a different Case engine or an earlier 580 model.

Hydraulics and Performance Testing

Hydraulic coverage goes beyond basic hose and cylinder service. The publication provides hydraulic-pump maintenance information, factory pump-output standards, system test data, and troubleshooting procedures for identifying performance loss. Engine stall testing is also documented, allowing engine output and hydraulic loading to be considered before a major component is removed.

That distinction matters when a machine shows weak digging performance or slow hydraulic response. Pump-output checks and stall-test results help prevent an engine-related problem from being treated as a pump failure—or a hydraulic fault from being blamed on the engine. The manual supplies the associated pressure-test specifications and adjustment data needed to evaluate the system under the correct test conditions.

Power Shuttle, Axles, and Drivetrain

The drivetrain chapters cover the power-shuttle transmission, including internal repair and rebuild references rather than only external adjustments. Differential-lock operation and four-wheel-drive front-axle service are also addressed, along with the applicable inspection and assembly information.

Super E power-shuttle torque requirements should not be replaced with specifications from an earlier Case 580 publication. The supplied material identifies torque data that changed for this model generation, which is particularly important during transmission reassembly and related drivetrain repair.

The front-axle material includes service procedures and load-rating information for the covered four-wheel-drive assembly. Before beginning backhoe or drivetrain work, the machine configuration should be matched to the correct section. Procedures and component arrangements for the standard 14-foot backhoe should not automatically be applied to the 14- to 18-foot Extendahoe version.

Electrical Diagnosis and Illustrated Procedures

Electrical chapters provide wiring diagrams together with battery and alternator troubleshooting information. The diagnostic material supports circuit tracing, charging-system testing, and fault isolation rather than limiting the coverage to component replacement.

Across the publication, 123 illustrated procedural sequences support component removal, engine stall testing, and electrical-system diagnosis. These illustrations give the reader visual reference points for assembly locations and service access while the surrounding text supplies the applicable inspection, repair, and test information.

Specifications and Shop Reference Data

The manual set contains component-specific torque tables, hydraulic performance standards, cooling-system capacities, drivetrain assembly data, front-axle ratings, and electrical test specifications. These references are tied to the covered systems and are intended to be used alongside the applicable repair procedure.

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.
