Case 580SR, 580SR+, 590SR, 695SR Series 3 Backhoe Loader Service & Repair Manual (P/N 87643852B)

This CNH Italia S.p.A. service manual, Print No. 87643852B, covers the Case 580SR, 580SR+, 590SR, and 695SR Series 3 loader backhoes.

Supplied as one 1,068-page PDF containing the loader-backhoe machine volume.

• Transmission repair: Turner powershuttle and Dana powershift removal, clutch and shaft overhaul, hydraulic pressure diagnosis, torque-converter stall testing, and fault-finding charts.

• Axles and brakes: Front and rear axle disassembly, differential and pinion setup, bearing preload, backlash adjustment, parking-brake adjustment, and brake bleeding.

• Hydraulics and steering: Pump, control-valve, cylinder, and steering-unit repair, with mechanical/pilot-control schematics, pressure-test data, and component views.

• Electrical diagnosis: Configuration-specific wiring diagrams, diagnostic-display self-tests, on-board error-code retrieval, and transmission, steering, loader, and backhoe component testing.

• Loader and backhoe: Attachment removal, loader bucket self-leveling, return-to-dig sensor adjustment, and telescopic-dipper guide-pad inspection, adjustment, and replacement.

• Cab heating and A/C: Heater diagnosis, refrigerant-system testing, flushing, evacuation, charging, and compressor repair, with dedicated service-equipment references.

Written for skilled service engineers, this manual assumes the workshop equipment and technical knowledge needed for machine-system diagnosis and overhaul.

Model Configurations and Engine-Service Scope

The model matrix distinguishes powershuttle and powershift versions, 2WD and 4WD layouts, 2WS and 4WS steering, sideshift and center-pivot backhoes, cab/ROPS equipment, and pilot versus mechanical attachment controls.

These distinctions help match the machine to the correct circuit diagrams before fault tracing. The 695SR is the 4WS configuration and is covered in both sideshift and center-pivot form.

Engine identification: The 580SR uses the 72 kW / 97 HP F4GE9484C*601 mechanical diesel. The 580SR+ uses the 72 kW / 97 HP F4HE0484G*J102 electronic common-rail engine with EDC7 control. The 590SR F4HE9484C*J102 and 695SR F4HE9484C*J103 are 82 kW / 110 HP electronic common-rail builds.

This volume contains engine identification and operating specifications, plus engine/transmission removal coverage. The dedicated engine service volume, Print No. 87659057A, is separate and is not included.

Turner and Dana Transmission Repair

The Turner COM-T4-2025 powershuttle has four forward and four reverse ratios. The Dana T16000 powershift has four forward and two reverse ratios, with electronic gear selection, clutch modulation, speed-sensor input, self-test functions, and fault diagnostics.

Coverage includes torque converters, clutch packs, shafts, oil and power flow, cooler circuits, solenoids, and valve bodies. Drawings include Transmission Hydraulic Valves and Pressure Test Points, the Dana T16000 Hydraulic Diagram, Torque Converter and Cooler System, and Servo Control Pressure System.

Factory data separates the two transmissions' pressure-test conditions, regulator and clutch pressures, cooler-flow checks, oil capacities, and temperature limits. CNH 380002693 is the shimming adapter; 380002689 is the input-shaft spring compressor.

The Turner repair notes flag displaced bearing cones and shim packs as a threat to correct shaft end float, and warn of shaft-sealing-ring damage during case fitting.

Carraro and CNH Axles, Brakes, and Steering

Axle sections cover the Carraro 26.00, 26.16, and 26.28 front-axle families, the CNH D46 2WS rear axle, and the Carraro 26.32M 4WS rear axle. Differential and pinion setup, wheel ends, wet-disc brakes, differential locks, bearing preload, backlash, and shimming are addressed separately.

Axle-specific tooling includes CNH 380002672 for pinion-bearing preload measurement. Steering coverage distinguishes the Danfoss OSPC 125 LS and OSPC 160 LS units, with overhaul procedures and test specifications. Fluid-capacity tables and wheel-nut torque specifications distinguish 2WS from 4WS machines.

Hydraulic Circuits and Attachment Service

Five machine hydraulic schematics distinguish 2WS/4WS, sideshift/center-pivot, and mechanical/pilot-control layouts, including Hydraulic Diagram - 4WS Center Pivot Pilot Models.

Component coverage includes the two-element hydraulic pump, load-sensing steering priority valve, Rexroth mechanical and pilot control valves, Parker "Glide Ride" accumulator, swing circuit, and hydraulic control levers. Accumulator coverage includes precharge checking and adjustment.

Cylinder repair covers the loader, backhoe, telescopic dipper, stabilizers, sideshift, and swing systems. CNH 380000721 is specified for telescopic-dipper and sideshift-stabilizer cylinder heads.

Attachment procedures distinguish center-pivot and sideshift backhoe removal. The telescopic-dipper repair notes warn that overtightening guide-pad retaining screws can damage the threaded inserts.

Before hydraulic repair, the manual requires attachments to be lowered or independently supported, the engine stopped, and residual circuit pressure relieved before lines, valves, or covers are opened.

Wiring Diagrams and On-Board Diagnostics

Electrical diagrams distinguish cab, ROPS, powershuttle, powershift, and 695SR 4WS combinations, including Electrical Diagrams - 4WS Powershift Cab (695SR). The 580SR+/590SR/695SR diagnostic-display section covers setup, self-tests, stored error codes, warning logic, and maintenance messages.

Starter, alternator, battery, transmission, 4WD, brake-switch, steering-selector, loader, and backhoe circuits receive dedicated test coverage. The 4WS steering-control-unit and axle steering-sensor sections include connector pinouts and electrical test values.

Cab Heating and HFC 134a Service

The A/C section contains performance-test diagnosis charts, manifold-gauge interpretations, and compressor overhaul procedures. Refrigerant-charge specifications identify HFC 134a, with PAG SP20 compressor oil.

A/C work is based on recovery/recharge equipment, including CNH 380000315, rather than releasing refrigerant.

PDF Search, Navigation, and Diagram Detail

The total includes 12 preliminary pages (cover, reader/safety information, model matrix, contents, and two blank pages) plus 1,056 section pages, including their divider and notes pages. Service text is searchable, but some hydraulic and electrical diagram labels are not; there are no embedded PDF bookmarks. Small wiring labels require zooming.
