Case 580C Construction King Backhoe Loader Operator’s Manual, 1975–1980 (P/N 9-4977)

This Case 580C Construction King Backhoe Loader Operator’s Manual (P/N 9-4977) covers operation and routine maintenance for Mechanical Shuttle (Dual Range) and Power Shuttle machines. It includes instructions for the standard backhoe and Extendahoe, with separate procedures where cab and canopy configurations differ.

PDF Search, Readability, and Page Count

Search, navigation, and legibility: The PDF has no embedded text search or bookmarks. Zooming in helps with the small labels in the fuel-system diagram and starter connection photos. Some specification and warning lines remain hard to read because the text is distorted.

The download contains one printable, English-language PDF with 185 pages. That total includes the front cover, two After Delivery Check forms, and two otherwise blank numbered pages.

Loader and Backhoe Operation, Adjustments, and Maintenance

Selected topics are listed below. The manual also covers trailer loading and preparing the machine for storage and return to service.

• Machine controls: Instrument cluster, shuttle shifting, differential lock, loader bucket controls, and foot-swing or twin-lever backhoe controls for standard and Extendahoe machines.
• Backhoe and attachments: Boom lock and transport position, backhoe removal and installation, three-point hitch setup and removal, drawbar use, and PTO operation.
• Engine, fuel, and cooling: G207D diesel maintenance, air-cleaner service, fuel-filter replacement and bleeding, thermostat testing and replacement, and fan-belt tension adjustment.
• Hydraulics and drivetrain: Hydraulic-filter service, equipment-pump removal for drive-spline lubrication, and separate oil-service instructions for the two shuttle systems and four-speed transaxle.
• Steering, wheels, and brakes: Power-steering filter replacement and air removal, front wheel bearing service, parking-brake adjustment, and clutch-pedal free-travel adjustment.
• Electrical system: Lamp identification and replacement, alternator charging-system precautions, battery maintenance, and starter connection photos keyed to a machine serial-number break.
• Specifications and charts: Fluid capacities, tire pressures, bucket capacities, ROPS mounting torques, maintenance intervals, and lift capacities for the standard backhoe and Extendahoe.

Case addresses the manual to the machine owner. Owners and operators can use it for daily checks and routine service. Backhoe mounting work calls for controlled positioning of the attachment and use of a torque wrench.

Shuttle Service and Front Wheel Bearings

The Power Shuttle oil-change procedure covers the torque converter and suction screen. The operating instructions warn that forcing the mechanical shuttle lever can clash the gears and shorten synchronizer life. For internal engine or transmission overhaul, use the separate service manual.

Front wheel bearing coverage goes through removal, inspection of the bearings and cups, hub and spindle seal replacement, and bearing adjustment.

Loader Settings and Rear Attachments

The mounting instructions give different tightening and follow-up checks for tension rods with one self-locking nut or two lock nuts. The Return-To-Dig illustrations help you match the fitted mechanism to the correct adjustment procedure. Both procedures call for checking the anti-rollback linkage first.

The three-point hitch section explains lift, pitch, and tilt. The manual also covers swinging and rigid drawbars, counterweight installation, and PTO tachometer-sensor adjustment. The standard backhoe lift charts distinguish boom-lock configurations, while the Extendahoe craning charts distinguish retracted and extended dipper positions.

Follow the manual’s hydraulic pressure-relief, raised-loader support, and backhoe transport-lock precautions before working around these components.

Fuel, Lubrication, and Electrical References

The fuel-system drawing traces the primary and final filters, transfer pump, injection pump, and return line. The bleeding section helps explain why the engine can restart after running out of fuel and still lose power or stall under load.

The Run-In Maintenance Chart, Scheduled Maintenance Chart, and Fuel, Fluids and Lubricants chart identify service points, intervals, and fluid requirements. Drive-shaft lubrication calls for needle-nozzle fitting D51765. The manual warns that a high-pressure grease gun can damage the parking-brake cable covering.

The battery section explains how to correct specific-gravity readings for electrolyte temperature. The starter photos identify the solenoid battery terminal and engine ground on the two starter configurations.

A Preview of Cooling and Belt-Service Data

The capacity table lists 21 U.S. quarts for the cooling system without a heater.

The fan-belt section gives gauge readings of 120 pounds of tension for a new belt and 80 pounds for a used belt.
