Case 580 D Backhoe Loader 1981 Service & Maintenance Manual (P/N 9-69270, 9-69271, 9-69272)

• Covers naturally aspirated and turbocharged 207 diesel engines in the Case 580D, with separate specifications and internal engine repair sections.
• Details engine-to-drivetrain removal and installation, including front engine support alignment and torque converter flex plate positioning with tool CAS-1153.
• Provides power shuttle troubleshooting, clutch and cooling circuit pressure tests, and torque converter and hydraulic stall tests.
• Explains hydraulic pump diagnosis and overhaul, with separate repair procedures for Parker-Hannifin and Hydreco loader control valves.
• Includes conventional front axle service and four-wheel-drive axle repair, covering planetary hubs, swivel housings, the differential, axle shafts, and transfer gearbox.
• Documents loader and backhoe removal, swing tower service, pivot bushing replacement, and work on standard and extendable dippers.

This 1,732-page PDF reproduces J.I. Case service information, comprising 1,726 service pages and six cover and navigation pages. It includes January 1981 sections and later revisions through August 1983; printed Case document references include 9-69270, 9-69271, and 9-69272. The manual is suited to experienced service technicians equipped for precision measurement, hydraulic testing, and lifting major assemblies.

Engine Diagnostics and Everyday Maintenance

Systematic engine diagnostics address hard starting, persistent misfires, overheating, and power loss. Separate troubleshooting coverage deals with excessive oil consumption and low oil pressure. Maintenance information includes lubricant recommendations, filter service, and capacity data for engine oil, coolant, and hydraulic systems.

The tune-up sections cover compression testing, injector spray checks, valve adjustment, injection timing, and governed-speed adjustment. Engine accessory coverage distinguishes the air cleaners used with turbocharged and naturally aspirated engines and addresses the ether injection system, radiator, and turbocharger failure analysis.

Roosa Master Model DB injection pump coverage includes removal and installation, drive shaft service, pump gear backlash checks, inlet filter replacement, and speed adjustments. The injector section goes further into nozzle identification, test-stand checks, disassembly, cleaning, and adjustment. It identifies the M20322 test stand and M20520 injector tool kit.

Precision Data and Engine Repair Procedures

Internal engine repair covers the cylinder head, valve train, camshaft, crankshaft, cylinder sleeves, pistons, connecting rods, and lubrication system. The turbocharged engine sections also address the oil filter heat exchanger.

Inspection data includes piston ring end gaps, main bearing oil clearances, camshaft tolerances, sleeve protrusion, and component-specific torque tables, including oil pan drain plug and manifold fastener specifications.

The shared 188/207 engine material identifies an engine serial break at 2072089 affecting rocker arm lubrication and rear camshaft bushing installation. This is an engine component distinction, not a machine serial-number coverage range.

One important installation warning concerns front engine support alignment: the manual explains how misalignment can damage the hydraulic pump or its coupling.

Power Shuttle, Transaxle, and Brake Service

The drivetrain sections cover forward and reverse clutch components, the shuttle charging pump, control valve, and clutch cutout controls. Pressure-test interpretation helps distinguish clutch circuit leakage from charging or cooling circuit faults.

Separate transaxle and differential lock sections apply to naturally aspirated and turbocharged machines. They document shaft and gear work, shifter assembly repair, differential bearing preload, and ring gear-to-pinion backlash adjustment. The self-adjusting differential brakes are likewise separated by engine configuration, with hydraulic brake cylinder service and pedal-to-transaxle linkage coverage.

Torque converter service is limited to diagnosis, removal, and replacement. The manual specifies replacement of a defective converter rather than internal overhaul.

Hydraulic Testing and Backhoe Configuration Differences

Six flowmeter tests cover loader and steering pump output, circuit leakage, and backhoe flow. Related procedures address main and secondary relief valves, neutral pressure, and the unloading valve. Test equipment references include the CAS-10280 flowmeter and CAS-1205 relief-valve test block.

The hydraulic sections distinguish standard and Super D backhoe valves, hand-swing and foot-swing controls, and machines with or without an extendable dipper. They also identify different boom and swing restrictor applications. Named references include the Backhoe Hydraulic Circuit on Machines with Hand Swing and Steering System Diagram for Loader Backhoe Machines.

Cylinder service covers glands, pistons, seals, and bushings. Attachment repair extends to dipper extension wear strips and guide blocks, bucket cutting edges, and tooth replacement, supported by the Extendable Dipper illustration. Optional three-point-hitch coverage includes one-spool and four-spool control valves.

Wiring, Instruments, and Cab Equipment

Electrical troubleshooting covers starting-circuit voltage loss, charging-system checks, starter and solenoid testing, alternator component tests, and instrument diagnosis. The Basic Wiring Diagram for Chassis and Cab and Air Conditioner Wiring Diagram accompany canopy lighting diagrams and instrument-cluster printed-circuit information.

Cab coverage includes air-conditioning fault diagnosis, pressure testing, compressor service, and refrigerant-system evacuation and charging procedures. ROPS cab and canopy, seat, seat belt, and noise-control sections round out the mounted-equipment coverage.

Review the factory safety procedures and torque standards before teardown, particularly where raised loader arms, hydraulic pressure, or heavy components are involved.
