Part of the Case Repair Manuals.
The 580 Super L and its 580L and 590 Super L stablemates are workhorses, and when a loader backhoe goes down it usually takes the whole job with it. This is the real factory service manual, part 7-48694, 1,468 pages covering the 4-390 diesel engine, fuel, electrical, steering, power train, brakes, hydraulics and mounted equipment, plus dedicated hydraulic and electrical schematic foldouts. Whether you are chasing a total loss of hydraulic power, an engine that stalls under load, or an overheat that shuts the machine down, it is here in factory order with the stall speeds and torque values to test against.

Case 580L, 580 Super L, 590 Super L Common Problems This Manual Covers
Complete loss of loader or backhoe hydraulic power
Loss of all hydraulic power usually traces to a failed hydraulic pump worn internally or damaged by contamination. Confirm it with the hydraulic stall speed test against the model spec, check the relief valve settings and the suction side for restriction, then service or replace the pump. The hydraulics section gives the pressures, stall values and pump procedure.
Manual Section: HydraulicsEngine stalls under load with no warning
A sudden stall under load is most often fuel starvation, a clogged fuel filter or a defective injection pump. Change the filters and check fuel supply and pump delivery, then confirm the low idle and full throttle speeds against spec. The fuel system and engine sections cover the injection pump service and the speed settings.
Manual Section: Fuel SystemEngine overheats and forces a shutdown
Overheating that forces a shutdown points to a blocked radiator or a failing water pump. Clean and check the radiator and cooling package airflow, test the water pump and thermostat, and verify coolant condition and level. The engine and general sections cover the cooling system service and the removal procedure if the radiator must come out.
Manual Section: EnginesFrequently Asked Questions
What does Case part number 7-48694 cover?
It is the full factory service manual for the Case 580L, 580 Super L and 590 Super L loader backhoes, 1,468 pages covering the 4-390 diesel engine, fuel, electrical, steering, power train, brakes, hydraulics and mounted equipment, plus full hydraulic and electrical schematic foldouts.
My 580 Super L lost all loader and backhoe power, where do I start?
Complete loss of hydraulic power usually points to a worn or contaminated hydraulic pump. The hydraulics section covers the pump, the relief settings and the stall speed tests to confirm it before you pull the pump.
What are the engine head bolt torque values?
The General section carries the standard torque specifications, including the 4-390 (Cummins 4T-390) cylinder head, along with the fluids and lubricants and the stall test values.
How do I read and clear an error code like E04?
The electrical section covers the instrument and error code display, what the fault codes mean, and the reset and diagnostic procedure.
Does it include the wiring and hydraulic schematics?
Yes. It has dedicated full schematic foldout sections, one for the 580L and one for the 580 Super L and 590 Super L, covering both the hydraulic and the electrical circuits.
