Case 580B Construction King Backhoe Loader Service Manual (Part No. 8-90721)

• Factory-standard 600-page technical reference for the 1970s Case 580B Construction King series, covering the complete build spectrum.
• Details both Diesel and Spark Ignition configurations alongside Hydrostatic and Shuttle drivetrain architectures.
• Features 47 exploded-view diagrams mapping out cylinder heads, rocker arms, fuel delivery setups, and timing gear assemblies.
• Defines exacting adjustment parameters for the 148, 159, 188, and 201 cubic-inch engine line.
• Official OEM publication (Form 9-80721) detailing comprehensive tractor specifications.

System Architecture and Component Data

Turning wrenches on a 580B requires accurate baseline data, not guesswork. This manual breaks down the operational framework for both engine configurations. You get the hard numbers on camshaft profiles, valve spring pressure thresholds, and valve guide dimensions tailored to specific engine displacements. For fuel delivery, the documentation zeroes in on Roosa-Master injection pump calibration and Zenith updraft carburetor baselines, including idle mixture and float adjustments. The hydraulic chapters map out the power steering circuits, control valves, and lift cylinders to streamline diagnostic work in the shop. Power train sections break down clutch pack specs and hydrostatic drive components. Note that working on pressurized hydraulic circuits and heavy driveline components carries inherent risks, so always verify system pressure relief procedures and use proper staging equipment before beginning heavy tear-downs.

Engine and Torque Specifications

Precision matters during a rebuild. The specification tables define absolute wear limits for cylinder sleeves, piston ring end gaps, and crankshaft bearing clearances specifically for the 188D and 188G blocks. Torque values are non-negotiable. You will find comprehensive charts detailing foot-pound requirements for main bearing caps, connecting rods, and flywheel mounting bolts. Intake valve clearance is firmly documented at 0.014 inches. The manual also outlines critical fluid parameters, such as the 2.5-quart hydraulic reservoir capacity. For diesel setups, it specifies a baseline fuel injection pump pressure of 2750 to 2850 PSI for new injectors.
