Case 580C Construction King Loader Backhoe 1975–1980 Operation and Maintenance Manual (P/N 9-4977)

This official 185-page manual (P/N: 9-4977, Sept 1977) provides the definitive operational and service data needed to keep Mechanical Shuttle, Power Shuttle, and Extendahoe models running properly in the shop or on the job site. Delivered as a searchable PDF, it delivers precise specifications for daily operations and routine upkeep.

A common trap when servicing the Case 580C is overlooking the specific torque sequencing on the backhoe mount tension rods, which can quickly lead to structural fatigue. Additionally, failing to accurately maintain the mechanical shuttle linkage often results in premature gear wear. Having the exact factory clearances and routing paths ensures that shop mechanics can efficiently verify systems without relying on generic, inaccurate aftermarket data.

Crucial Shop Data & Specifications

• Fluid Capacities: Accurately service the 22-gallon fuel tank and the 21-quart coolant system (for standard models).
• Engine & Hydraulics: Verifies the 16.5:1 engine compression ratio for the G207D diesel build. Essential hydraulic system relief pressure is documented at a strict 2200 ± 50 psi (15168 ± 345 kPa).
• Torque Values: Includes vital multi-stage torque processes, such as securing backhoe mount tension rod nuts to 450–550 ft-lbs (610–745 Nm).
• Cockpit Controls: Complete layout mapping for instrument clusters, shuttle shifting, and standard/twin-lever/Extendahoe control patterns.
• Daily Operations: Detailed charts for loader bucket capacities, tire pressure configurations, PTO engagement, and precise drawbar settings.
• Core Machine Components: Covers the Case 580C Construction King, G207D diesel engine, four-speed transaxle, power steering system, and ROPS cab.
• In-House Procedures: Guides covering backhoe removal, 3-point hitch setup, parking brake adjustment, alternator service, fan belt alignment, and electrical system checks.

Step-by-step guides for complex tasks—such as backhoe removal and installation, three-point hitch setup, and precise PTO adjustments—allow owners to perform heavy labor directly in their own bays, bypassing expensive heavy equipment repair shop fees. To further assist with accurate troubleshooting, the document incorporates a Run-In Maintenance Chart, a Scheduled Maintenance Chart, a comprehensive Fuel and Lubricants Chart, and exact Backhoe Lift Capacity charts.

Safety & Proper Operation Working on heavy construction machinery poses severe high-pressure fluid and crushing hazards; always verify pressure relief and transport lock protocols before disconnecting hydraulic lines. Always review the 47 included safety warning illustrations before performing scheduled maintenance, adjusting return-to-dig settings, or handling cold/hot weather startups to protect yourself and your equipment.
