2008 Ducati Superbike 848 Service & Repair Manual

The 2008 Ducati Superbike 848 service manual covers maintenance, diagnosis and repair of the L-twin engine, chassis and electrical systems, with European identification data and US-specific emissions-system coverage.

• Engine and valve timing: Engine removal, cylinder-head overhaul, Desmodromic valve-clearance adjustment, timing-belt replacement and camshaft timing checks.

• Clutch and gearbox: Wet-clutch troubleshooting and plate inspection, primary-drive backlash checks, gearbox disassembly, selector-fork inspection and shaft shimming.

• Fuel injection and ignition: Ducati Diagnostic System procedures, throttle-position sensor reset, throttle-body balancing, fuel-pressure testing and ignition-component checks.

• Cooling and lubrication: Water-pump bearing and seal replacement, oil-pump inspection, radiator and cooling-fan removal, coolant changes and lubrication-system testing.

• Suspension and brakes: Showa front-fork overhaul, rear-suspension linkage service, wheel and steering-bearing work, and Brembo brake maintenance and bleeding.

• Electrical systems: Wiring diagrams, harness-routing plates, charging and starting-system tests, instrument-panel fault displays and immobilizer service procedures.

Written for technical personnel at Ducati Authorized Service Centers, this manual assumes experienced, skilled technicians who can follow the factory procedures and use the specified workshop equipment.

Engine Overhaul and Desmodromic Timing

Engine coverage extends to valve guides and seats, cylinder/piston inspection, crankshaft and connecting-rod checks, crankcase separation and bearing shimming. Inspection data include crankshaft ovality limits, piston-to-bore clearances and component size-class matching.

Valve-timing diagrams accompany the camshaft checks. The DDS optical belt-tension procedure allows both belts to be checked with the engine installed in the frame, avoiding engine removal for that measurement. The tool references include crankshaft holder 88713.2011 and camshaft timing tools 88765.1524.

The timing-pulley instructions warn that reused self-locking nuts can loosen and cause serious engine damage. The connecting-rod section distinguishes SPS and LISI single-use cap bolts, their different tightening checks and the lubrication precautions needed to prevent component breakage.

Clutch exploded views support plate-pack inspection and reassembly. Troubleshooting separates failure to disengage, slipping and noise, while the gearbox chapters explain selector inspection and shim selection.

DDS Diagnosis, Fuel System and Electrical Checks

The Marelli 5AM2 engine-management coverage explains sensor inputs, injector and ignition control, and communication with the instrument panel over the CAN line. DDS procedures cover stored faults, actuator tests, oil-pressure and compression measurements, and service-indicator reset.

Throttle-body service: TPS reset is specified after replacement of the throttle body, ECU or wiring. The TPS is replaced with the throttle-body assembly rather than serviced separately. The idle-adjustment section also explains why correct idle speed takes priority over matching cylinder vacuum.

Fuel-system work includes tank-flange and filter service, injector removal and exhaust-valve cable positioning. A separate US-version EVAP section covers canister removal, installation and hose routing.

Electrical references: The main wiring diagram, fusebox key and harness-routing plates connect circuit information with component locations. Starter-interlock checks and instrument-panel error tables support fault isolation. Immobilizer override and reprogramming procedures require the electronic code from the Code Card.

Keep the workspace well ventilated during engine-running checks and wear protective gear when handling DOT 4 brake fluid.

Showa Suspension, Brembo Brakes and Chassis

The front-fork chapter includes disassembly, inspection and reassembly. Rear-suspension coverage addresses the rocker-arm bearings and tie-rod; the rear-shock section covers spring removal, inspection and replacement of the shock assembly.

Service limits: Brake caliper and master-cylinder work is limited to the specified service items; internal overhaul is discouraged. Similar restrictions apply to the hydraulic clutch master and slave cylinders. Internal overhaul of the rear eccentric hub is expressly prohibited; the hub is supplied as a complete assembly.

Frame dimensional checks, fairing removal, wheel inspection, steering-head service and final-drive replacement procedures complete the chassis coverage.

Water-Pump and Oil-System Repair

Water-pump sectional views show the bearing and mechanical-seal arrangement. Oil-pump bypass-valve inspection, oil-cooler removal and installation, and radiator/thermostat hose-routing illustrations provide detail beyond routine fluid changes.

A Preview of Belt, Fluid and Fastener Specifications

The belt-tension table specifies 110±5 Hz with the engine cold for both cylinders, for new-belt installation and used-belt resetting. The fluid table lists 3.7 liters for the engine lubrication circuit.

For fasteners lubricated with the specified GREASE B, the chassis torque tables list 186 Nm ±5% for the front sprocket retaining nut and 30 Nm ±10% for the steering stem nut. These entries accompany the component procedures and their assembly requirements.

Searchable Text, Bookmarks and Wiring Detail

Navigation and diagram limitations: Body text is searchable, and embedded bookmarks provide access to the manual’s sections. Labels within wiring illustrations are not searchable. The main wiring diagram spans two PDF pages; some small ECU pin and wire-color labels remain difficult to read even when enlarged.

Supplied as one printable English PDF with 774 pages, including one opening title/navigation page, 15 general contents pages and 19 section contents pages.
