2006 Ducati 999/999S Factory Service Manual (Edition 00)

• Covers the 2006 Ducati 999 and 999S (M.Y. 2006, Edition 00), with applicable Biposto/two-seater and Monoposto/single-seater differences, European and U.S. identification data, and 636 bilingual Italian/English PDF pages. The 999R is not included.
• Documents complete Testastretta engine removal and installation; oil-pump, oil-cooler, coolant-manifold, and water-pump service; valve-clearance, valve-lift, and cam-timing checks; timing-belt work; and overhaul of the heads, rocker arms, cylinders, pistons, crankcases, crankshaft, and connecting rods.
• Takes dry-clutch and six-speed gearbox repair beyond external adjustment, covering clutch-pack inspection, primary-drive meshing play, selector mechanism and shaft disassembly, fork and drum inspection, transmission overhaul, shaft shimming, and flywheel-generator service.
• Builds diagnostic work around the Ducati Diagnosis System (DDS), including timing-belt tension measurement, TPS reset, throttle-body balancing, engine-oil and fuel-pressure tests, cylinder compression testing, guided fault diagnosis, charging-current checks, immobilizer unlocking, and service-indicator reset.
• Separates key 999 and 999S chassis procedures for the Showa and Öhlins front forks, rear shocks, steering dampers, and front brakes, while also covering wheels, steering-head adjustment, swingarm and rear linkage overhaul, final drive, adjustable steering geometry, and frame inspection.
• Supplies injection-ignition and electrical fault-finding material, component checks, connector data, torque tables, fluid specifications, inspection and wear limits, clearances, adjustment data, and electrical test values for the covered assemblies.

Workshop Level and Variant Coverage

Ducati prepared this workshop manual for Authorized Service Centres and workshop personnel and states that its procedures are to be carried out by senior skilled technicians. It assumes the reader already has core trade knowledge and access to factory-type measuring equipment and special tools, making it a shop-level repair reference rather than an entry-level maintenance guide.

The variant detail is practical, not limited to a model-name note. The manual distinguishes the 999's Showa suspension and brake hardware from the 999S Öhlins fork, shock, and steering damper and 999S-specific front brake components. It also identifies two-seater and single-seater frame and rear-subframe arrangements, passenger-seat and seat-lock work, single-seat adjustment, and the U.S.-market 999S evaporative canister system. European and U.S. frame and engine marking formats are included to help confirm the motorcycle before repair data are selected.

Diagnostics, Diagrams, and Factory Tools

The I.A.W. 5AM2 section explains sequential injection, ignition control, ECU inputs, CAN communication, and how the stored mapping is used. It does not provide editable fuel or ignition maps; Ducati states that the factory calibration values are preset and cannot be changed. DDS coverage goes further than code reading by pairing self-diagnosis with actuator access, live parameters, component locations, system documentation, and guided diagnostic screens.

Named visual references include the injection-ignition system diagram, the sectioned Diagram A-Y electrical schematics, wiring-harness arrangement on the frame, instrument-panel connector pinout, starter safety-functions table, and exploded clutch/gearbox assembly views. The service-tool tables identify the DDS and cylinder-vacuum kit P/N 97900.0215, crankshaft TDC locking tool 88713.2011, timing degree wheel 98112.0002, cam-timing tools 88713.1791, and Showa fork-seal installation tool 88713.1096.

The timing chapter highlights a genuine repair trap: reused belts must remain assigned to their original cylinder and direction of rotation, while the timing-roller self-locking ring nuts are one-time-use parts because loosening can cause severe engine damage. Brake and clutch hydraulic coverage also has a firm boundary. Ducati limits internal service of the brake calipers, brake master cylinders, and clutch slave cylinder because incorrect overhaul of these safety-critical units can endanger the rider; the manual instead defines the permitted external parts and complete-assembly replacements.

This factory manual includes pre-delivery checks, scheduled service, major disassembly and reassembly, and final adjustment data, but it is not a spare-parts catalog. Ducati notes that some component-installation information must be taken from the separate parts catalog and that basic specialist knowledge is intentionally omitted.
