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

This Case 580C Construction King Operator's Manual (P/N 9-4977) covers loader-backhoe operation and maintenance for Mechanical Shuttle, Power Shuttle, and Extendahoe configurations.

• Controls and operation: 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: Backhoe removal and installation, cab/canopy differences, mounting tension rods, boom lock, three-point hitch removal and installation, and drawbar use.

• 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: Equipment-pump removal for drive-spline lubrication, hydraulic-filter service, Power Shuttle suction-screen cleaning, and mechanical-shuttle and four-speed transaxle fluid service.

• 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 replacement, alternator charging-system precautions, battery maintenance, and starter-connection illustrations divided by machine serial number.

• Specifications and charts: Fluid capacities, tire pressures, bucket data, ROPS mounting torques, maintenance charts, and standard backhoe and Extendahoe lifting-capacity charts.

Owners and operators can use the daily service guidance, while attachment removal and mounting work assumes familiarity with lifting equipment and torque wrenches.

Shuttle Service, Steering, and Repair Scope

Mechanical Shuttle/Dual Range and Power Shuttle models have separate oil-service instructions alongside the four-speed transaxle section. Power Shuttle coverage includes the torque converter and suction screen; steering coverage includes reservoir-filter replacement and air removal.

Front wheel bearing repair includes removal, inspection, and seal replacement. Internal engine and transmission overhaul requires separate service documentation.

The mechanical-shuttle operating instructions warn that forcing direction changes causes gear clash and shortens synchronizer life.

Loader Settings and Rear Attachments

Backhoe removal and installation distinguish cab and canopy machines. Mounting instructions separate tension rods with a single self-locking nut from those with two lock nuts, with different tightening procedures and follow-up checks.

The Return-To-Dig sections distinguish the earlier switch-bracket arrangement from the later actuating-rod system and relate both to anti-rollback adjustment. The illustrations help match the fitted mechanism to the appropriate adjustment procedure.

Three-point hitch coverage explains lift, pitch, tilt, and implement controls. Swinging and rigid drawbars, counterweight installation, PTO operation, and PTO tachometer-sensor adjustment are also covered.

Engine Maintenance and Lubrication References

The fuel-system drawing traces the primary and final filters, transfer pump, injection pump, and return line. The air-removal section explains how air remaining after filter service or fuel starvation can cause power loss and stalling under load.

The Run-In Maintenance Chart, Scheduled Maintenance Chart, and Fuel, Fluids and Lubricants chart organize service points and fluid selection. Drive-shaft lubrication calls for needle-nozzle fitting D51765.

The parking-brake cable lubrication notes warn that a high-pressure grease gun can damage the cable covering.

Electrical Care and Operating Limits

Electrical coverage includes bulb identification, alternator handling precautions, and battery specific-gravity checks with temperature correction. Starter-connection photos distinguish the configurations before and after the documented serial-number change.

Standard backhoe lift-capacity charts distinguish boom-lock configurations. Extendahoe craning charts separate retracted and extended dipper positions, with the applicable equipment and loading conditions.

Loader bucket data, ROPS inspection, seat-belt care, and cold- and hot-weather operation support machine setup and use. Working on heavy construction machinery poses high-pressure fluid and crushing hazards; follow the manual's pressure-relief, raised-loader support, and transport-lock precautions before service.

A Preview of Cooling and Belt-Service Data

The following figures are a small selection of the maintenance specifications in this manual.

Cooling-system capacity is 21 U.S. quarts without a heater.

The fan-belt section specifies 120 pounds of tension for a new belt and 80 pounds for a used belt when checked with a belt tension gauge.

PDF Search, Readability, and Page Count

Search, navigation, and legibility: PDF text search and embedded bookmarks are not available. Small labels in the fuel-system diagram are readable when enlarged. Some specification and warning lines are visibly stretched or blurred and remain difficult to read.

Supplied as one printable, English-language, 185-page PDF. The total includes the front cover, two After Delivery Check forms, and two otherwise blank numbered pages.
