Ducati Multistrada 620 & Dark Workshop Manual — 2006

Ducati factory workshop manual for the 2006 Multistrada 620 and Multistrada 620 Dark, edition 00. Covers maintenance, diagnosis, and engine and chassis repair, with English and Italian text.

PDF Search, Navigation, and Diagram Detail

Search and wiring detail: PDF text search and embedded bookmarks are not available. Small wiring labels require zooming; some closely packed ECU labels remain soft or faint when enlarged.

The ZIP contains one printable, 549-page PDF: 522 pages of workshop sections and their dividers, one front cover, 10 pages of opening contents, a 10-page subject index section, and six blank pages. All are already included in the total.

Engine, APTC Clutch, Chassis, and Electrical Coverage

The following selected topics show the manual’s scope rather than reproduce its full contents. Other subjects include pre-delivery checks and resetting the instrument-panel maintenance indicator.

• Engine repair: Engine removal and installation, oil-pump overhaul, cylinder-head and cylinder/piston service, crankcase separation, main-bearing setup, and connecting-rod repair.

• Desmodromic valvetrain: Valve-clearance inspection and adjustment, shim measurement, camshaft service, engine-timing verification, and timing-belt and pulley removal and installation.

• Clutch and gearbox: APTC wet-clutch disassembly and inspection, primary-drive service, selector-linkage adjustment, gearbox-shaft overhaul, and shift-fork and drum checks.

• Chassis and hydraulics: Wheel, front-fork, and swingarm overhaul; rear-shock removal and installation; suspension-rocker service; steering adjustment; and brake and clutch bleeding.

• Mathesis diagnostics: Tester connection, stored faults, live parameters, active component tests, throttle-body setup, timing-belt frequency measurement, oil-pressure testing, and cylinder-compression checks.

• Electrical and service references: Injection–ignition schematics, frame wiring layout and plates A–Y, torque tables, fluid capacities, wear limits, electrical test data, and illustrated special-tool lists.

Ducati wrote this manual for authorized service-center and workshop personnel. Its procedures require skilled technicians with established trade knowledge, rather than readers learning mechanical repair from the beginning.

Cylinder Heads, Timing, and Internal Engine Work

The engine chapters provide step-by-step procedures supported by inspection criteria. Cylinder-head work includes valves, guides, seats, rocker arms, and opening and closing shims. Camshaft coverage adds bearing and seal inspection, valve-lift checks, and timing verification.

Cylinder and piston sections distinguish selection classes and explain matching components. Crankcase work continues through main-bearing replacement and crankshaft shimming, with connecting-rod inspection, bearing-clearance measurement, and reassembly.

Timing-system cautions: The manual identifies pulley and flange timing-mark alignment and specifies new self-locking roller ring nuts. It warns that accidental loosening of reused ring nuts can damage the engine.

APTC Clutch and Gearbox Setup

The APTC section explains clutch operation and lists possible causes of slipping, failure to disengage, and noise before covering component inspection. Measurements address the plates, housing, pressure plate, and springs.

Gearbox coverage includes the selector interlock and pawl, primary and secondary shafts, selector forks, and drum. Shaft and drum shimming procedures lead into checks of gear engagement and coupling-dog alignment. Flywheel/generator work includes starter-clutch inspection and engine-sensor gap checks.

Standard and Dark Brakes, Suspension, and Frame

The DARK MONODISCO version uses a single front disc and left-hand caliper; the standard model uses the twin-disc arrangement. These distinctions help identify the appropriate brake components and procedures. Technical tables also distinguish the restricted-output engine specification.

Chassis chapters cover bodywork and fuel-tank access, steering components, wheel bearings, the upside-down front fork, rear swingarm, shock absorber, suspension rocker arm, and chain final drive. Frame checks include dimensional drawings for the frame and front subframe.

Hydraulic-service limits: Brake and clutch coverage includes removal, installation, hose routing, external maintenance, and bleeding. The component manufacturers advise against internal overhaul of the master cylinders, clutch slave cylinder, and brake calipers; the manual identifies the permitted replacement work.

Use the manual with the motorcycle securely supported, the electrical system isolated where specified, and proper protection when handling brake fluid and loaded mechanical assemblies.

Fuel Injection, Instrumentation, and Electrical Diagnosis

Fuel-system chapters cover the tank flange, throttle body, airbox, exhaust, catalytic converter, and U.S.-version evaporative canister. Throttle-body setup includes potentiometer reset, airflow balancing, and CO adjustment using Mathesis, a vacuum gauge, and an exhaust-gas analyzer.

The manual links throttle-cable work to throttle-body adjustment because cable work can disturb the setting. That connection helps keep related adjustments together during service.

Electrical sections cover charging and starting tests, lighting and signaling, fuses, safety switches, and multimeter checks. Instrument-panel information includes EFI fault identification and connector pinouts; immobilizer coverage includes key programming and verification.

Assembly Drawings and Ducati Tools

Illustrations include injection–ignition schematics, wiring locations on the frame, and timing-system, front-fork, APTC-clutch, gearbox, and crankcase assembly views.

Factory tool references include timing-pulley tools 88700.5644 and 88713.2107, crankshaft lock 88713.2011, valve and rocker tools, pullers, bearing drivers, fork tools, and Mathesis pressure and belt-tension kits.

Some installation details are referenced to the separate parts catalog. Later Ducati Technical Bulletins can supersede individual procedures.

A Preview of Oil-Pressure and Compression Data

With engine oil at least 80°C, the oil-pressure specifications call for more than 0.8 bar at 1,100–1,300 rpm and more than 4 bar at 3,500–4,000 rpm.

For cylinder-compression testing, the standard range is 9–11 bar with the engine warm, the throttles fully open, and battery voltage at least 12.5 V measured with no load.
