Component and Systems Overview

The model matrix is especially useful because these machines are not all built the same. It 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. The 695SR is the 4WS configuration and is covered in both sideshift and center-pivot form.

Engine identification data helps match the machine configuration before repair work begins. The 580SR uses the 72 kW / 97 HP F4GE9484C601 mechanical diesel, rated at 400 Nm at 1400 rpm. The 580SR+ uses the 72 kW / 97 HP F4HE0484GJ102 electronic common-rail engine with EDC7 control and 453 Nm at 1400 rpm. The 590SR F4HE9484CJ102 and 695SR F4HE9484CJ103 are 82 kW / 110 HP electronic common-rail builds rated at 516 Nm at 1400 rpm.

Transmission coverage goes far beyond removal notes. The Turner COM-T4-2025 powershuttle has four forward and four reverse ratios, while 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, oil flow, pressure test points, power flow, cooler circuits, solenoids, valve bodies, gear and clutch layouts, teardown, assembly, and fault finding.

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, shimming, and axle-specific tooling are addressed separately.

Hydraulic, Electrical, and Diagnostic Coverage

Five machine hydraulic schematics distinguish 2WS/4WS, sideshift/center-pivot, and mechanical/pilot-control layouts. 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, hydraulic control levers, and the loader, backhoe, telescopic-dipper, stabilizer, sideshift, and swing cylinders. Steering system pressure is 177 ± 3 bar, with separate data for the Danfoss OSPC 125 LS and OSPC 160 LS steering units.

Electrical sections include wiring diagrams for the major cab, ROPS, powershuttle, powershift, and 695SR 4WS combinations. The 580SR+/590SR/695SR diagnostic display coverage includes setup, self-test, on-board error-code retrieval, warning logic, maintenance messages, and component testing. Starter, alternator, battery, transmission, 4WD, brake-switch, steering-selector, 4WS steering-control-unit, axle steering-sensor, loader, and backhoe circuits receive dedicated test coverage.

Representative named diagrams and views include Transmission Hydraulic Valves and Pressure Test Points, Dana T16000 Hydraulic Diagram, Torque Converter and Cooler System, Servo Control Pressure System, Hydraulic Diagram – 4WS Center Pivot Pilot Models, and Electrical Diagrams – 4WS Powershift Cab (695SR).

Specification Highlights

The test values are configuration-specific. Turner powershuttle hydraulic checks use an 80–85°C oil temperature, with system, forward-clutch, reverse-clutch, and 4WD supply pressures at 13.7–15.2 bar and torque-converter pressure at 7–11 bar. Dana T16000 pressure and flow checks are referenced at 82–93°C; regulator pressure is 19.6–23.1 bar at 2200 rpm, activated clutch pressure is 18.1–21.5 bar, and maximum allowed transmission temperature is 120°C.

Powershuttle oil capacity is 18 L and powershift capacity is 14 L. The main hydraulic system holds 140 L on 2WS machines or 118 L on 4WS machines. Wheel-nut torque is 330 Nm front / 540 Nm rear on 2WS, versus 700 Nm front and rear on 4WS. The air-conditioning section specifies HFC 134a with a 1.2 kg refrigerant charge and PAG SP20 compressor oil.

Factory Procedures and Repair Detail

Factory procedures include torque-converter stall testing; Turner and Dana transmission removal, clutch and shaft repair, and pressure diagnosis; differential and pinion preload/backlash setup; parking-brake adjustment and brake bleeding; hydraulic pump, control-valve, and cylinder repair; steering-unit overhaul; A/C flushing, evacuation, charging, and compressor repair; electrical self-tests and error-code retrieval; loader removal; center-pivot and sideshift backhoe removal; and telescopic-dipper guide-pad inspection, adjustment, and replacement.

Special-tool references are tied to specific jobs. Examples include CNH 380002693 shimming adapter, 380002689 input-shaft spring compressor, 380002672 pinion-bearing preload measuring tool, 380000721 hydraulic-cylinder head wrench, and 380000315 HFC 134a recovery/recharge system.

The repair notes also flag mistakes that can turn an overhaul into another teardown. On the Turner transmission, bearing cones and shim packs can come free with the rear case, so mixing their original locations compromises the shaft end-float setup. Shaft sealing rings are installed only after shimming is complete to prevent them from being damaged during repeated case fitting. On the telescopic dipper, guide-pad retaining screws are specified at 29–31 Nm; over-tightening 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. A/C work is based on HFC 134a recovery/recharge equipment rather than releasing refrigerant.

Scope of This Volume

Print No. 87643852B is the loader-backhoe machine volume. It contains engine identification and operating specifications, but CNH lists the dedicated Engine service manual separately as Print No. 87659057A. This distinction is important when selecting documentation for machine-system repair versus dedicated engine service.
