• Engine repair: Covers engine removal, cylinder-head work, timing-drive replacement, full bench overhaul, crankshaft/piston/valve inspection, turbocharger service, cooling and lubrication work, mechanical injection-pump service, and Bosch Common Rail diagnosis.
• Clutch, transmission, and final drive: Documents clutch repair; overhaul of the 5 S 200/270/300, 6 S 300, and 6 S 380 O.D.; 6 AS 300 VD actuator/ECU work and calibration; PTO service; propeller-shaft checks; and rear-axle overhaul.
• Axle, suspension, and steering systems: Breaks out front axles 5817, 5818, 5819, and 5823; leaf-spring and torsion-bar suspensions; WABCO ECAS and VB-Techniek rear air suspension; wheel geometry; and ZF/TRW power-steering tests and repair.
• Brake and climate-control work: Provides brake circuit layouts, ABS/EBD/ABD and ABS 8/ESP 8 diagnosis, programming, calibration, bleeding, and brake repair, plus R134a recovery, evacuation, charging, leak detection, and pressure checks for Marelli and Denso HVAC equipment.
• Electrical and diagnostic coverage: Maps harnesses, connectors, pinouts, grounds, and circuits for MS6.3/EDC 16, 6 AS 300 VD, ABS/ESP, ECAS, airbags, immobilizer, cruise control, PTO, Telma retarder, and fitted options.

Match the Vehicle by Its Installed Assemblies

The May 2004 and February 2005 dates identify the publication and revision, not a blanket vehicle model-year range. The manual organizes fitment by Daily model code and installed assemblies, so the vehicle's engine, transmission, axle, suspension, and electrical configuration should be matched before purchase. It is expressly written for qualified, specialized personnel and assumes access to the specified Iveco tools and diagnostic equipment, including MODUS, IT 2000, and E.A.SY. It is not a beginner-level maintenance guide.

Engine and Drivetrain Detail

The 8140 material separates the 8140.43R/B/S/N electronic high-pressure injection engines from the 8140.43C and 8140.63C rotary mechanical-pump versions. The F1A and F1C chapters carry the repair coverage through complete engine overhaul, Common Rail component testing, ECU-controlled injection, EGR, fixed- and variable-geometry turbocharging, and fault isolation by stored code or symptom.

For the 8140.43S, engine No. 3089322 marks the rail configuration without flow limiters and a pressure-relief valve. The MS6.3 section identifies the onboard blink-code procedure for vehicles up to chassis No. 5383302/D187233.

The transmission chapters go beyond removal. They cover shaft, gear, bearing, synchronizer, selector, and end-float work on the manual units. For the electro-mechanical 6 AS 300 VD, the publication adds control-unit, clutch-actuator, gearbox-actuator, and harness work, followed by the required diagnostic calibration. Rear-axle sections cover types 450210, 450311/1, 450511, 450517/2, and 450310, including hub repair, differential-lock adjustment, pinion depth, bearing rolling torque, backlash, and tooth-contact checks.

Diagrams, Tools, and Specifications

The electrical circuit-chart index runs from Chart 1A through Chart 58. Representative examples are the EDC 16 EGR/exhaust-gas control circuit, WABCO ECAS/VB-Techniek air-suspension schematics, airbag and pretensioner wiring, ABS 8/ESP 8 charts, and the 6 AS 300 VD automatic-transmission circuit. Mechanical illustrations add rear-axle section views with ring-and-pinion contact patterns.

Factory tool lists identify equipment by number, including timing tool 99360608, transmission support 99370629, brake/clutch bleeding equipment 99306010, and R134a recovery/refilling station 99305146. Related chapters supply torque tables, assembly clearances, wear limits, fluid capacities, pressure-test values, sensor/actuator specifications, pin data, and fault-code tables. Separate maintenance schedules cover 8140-, F1A-, and F1C-powered vehicles.

Scope Limits and Repair Cautions

This volume does not contain the full bodywork and chassis-frame repair material; Section 12 directs those subjects to separate publication 603.43.606. Its own Section 12 covers cab air conditioning and the related component procedures, while airbag and pretensioner information appears in the steering and electrical material.

The Common Rail chapters state that removed high-pressure pipes are not reused and that injector nozzle bodies and electromagnets are not to be dismantled; contamination or disturbed fittings can damage calibrated components or compromise high-pressure sealing. In the axle chapters, the ring gear and pinion are treated as a matched pair, and the specified shim positions, rolling torque, backlash, and tooth contact must be restored to avoid final-drive damage.

Engine, transmission, axle, brake, refrigerant, and high-pressure fuel work requires suitable lifting and test equipment. Follow the manual's isolation, cleanliness, support, and final-check procedures for the exact vehicle configuration.
