CASE 580M 590M Backhoe Loader Service Manual PDF — Complete Workshop Guide

If you service CASE backhoe loaders in a production shop, you already know that guessing torque specs or hunting for hydraulic pressure test points through forum posts costs real money per job. The CASE 580M and 590M service manuals fix that problem permanently — every specification, every circuit, every procedure is documented to factory standard.

This guide walks through what the official service manual covers, which subsystems are fully documented with schematics, and why workshops running multiple CASE backhoe models keep the complete collection on hand.

What the CASE 580M / 590M Service Manual Covers

The official CNH service manual for the 580M, 580 Super M, 580 Super M+, 590 Super M, and 590 Super M+ is organized into discrete sections, each covering a complete system:

• Engine — Tier 3 Compliance: The 4T-390 turbocharged diesel produces 95 hp. The manual covers injection timing, valve clearance (intake 0.30 mm / exhaust 0.30 mm cold), and fuel system bleeding procedures step by step.
• Powershift Transmission: The 580M runs a 4-speed powershift. The manual includes clutch pack clearance specifications, solenoid valve test procedures, and the full hydraulic circuit for the transmission control valve.
• Loader Hydraulics: Boom, bucket, and auxiliary circuit schematics with all pressure test points identified. Main relief valve setting: 220 bar (3,190 psi). Auxiliary relief: 207 bar (3,000 psi).
• Backhoe Hydraulics: Dipper, bucket, swing, and stabilizer circuits — each with the test port location and correct pressure specification for troubleshooting no-dig or slow-dig complaints.
• Electrical System: Full wiring harness diagrams by circuit — charging, starting, instrument cluster, HVAC, lights, and the SAHR park brake control. Connector locations identified on the machine.
• Axles & Brakes: Front axle disassembly with bearing preload specs, rear axle differential service, and wet disc brake adjustment procedures.

Hydraulic System Pressure Specifications (580M)

These are the values you verify at the test ports documented in the manual:

• Main system relief: 220 bar / 3,190 psi
• Pilot circuit relief: 35 bar / 508 psi
• Transmission charge pressure: 13–17 bar at operating temperature
• Steering circuit relief: 172 bar / 2,500 psi
• Backhoe swing circuit: 193 bar / 2,800 psi

Which Models Are Covered in the Full Collection?

The CASE CNH Backhoe Loader collection includes 249 PDFs spanning every series produced under the Case, Fiat-Allis, and New Holland badges:

• Case K Series — 580K Phase 1, Phase 3, Super K

• Case M Series — 580M, 580SM, 580SM+, 590SM, Series 1 through 3, Tier 2 and Tier 3
• Case N Series — 580N, 580SN, 580SN WT, 590SN (current production)
• Case R Series — 580 Super R, 590 Super R
• Case T Series — 580T (Tier 4 Final)
• Fiat-Allis — FBL series with hydraulic schematics

Electrical and hydraulic schematics for all N-series and T-series machines are included via the CASE CE Electrical Schematics bundle that accompanies every purchase.

Who Needs This Manual Set?

Independent service shops running CASE backhoes benefit most — dealer access to CNH Service Information (SI) requires an active subscription that costs more per year than this entire collection. Rental fleet operators with mixed CASE/New Holland fleets use it to standardize workshop documentation across machine brands. OEM component rebuilders working on transmission, axle, or hydraulic cylinder exchanges rely on the exploded-view parts diagrams and clearance specs that are not published anywhere else.

Download and Access

After purchase you receive an instant access link to a browseable folder containing all 249 PDFs. You can navigate by series (K, L, M, N, R, T), by brand (Case, Fiat-Allis, New Holland), and by document type. Every PDF is searchable — type a fault code, component name, or part number and find the relevant procedure in seconds.

Frequently Asked Questions

Does the 580N manual include the Tier 4 Final engine?
Yes. The N-series manual covers both the Tier 4 Interim and Tier 4 Final engine variants. The 580T manual provides the updated fuel system and DPF regeneration procedures for Tier 4 Final machines.

Is the electrical schematic a separate file or inside the service manual?
The main service manuals contain the wiring diagrams for their generation. The dedicated CASE CE Electrical Schematics PDFs (included in this collection) provide the full-page A3-format schematics used for harness-level diagnosis on N-series and later machines.

Can I print individual diagrams?
All files are standard PDF — print any page at any scale using any PDF reader. No activation, no DRM, no page-print limits.
