2007 Moto Guzzi Bellagio 940 Repair Manual (P/N 854366)

This 403-page PDF set covers the 2007 Moto Guzzi Bellagio 940, identified as GU08700 in the parts catalog and by model code LY in the factory chassis-number format. It combines the 209-page English Service Station Manual (factory document no. 854366), a 136-page Spanish/English owner's booklet (Ed. 04/2007), and a 58-page illustrated parts list. The workshop manual was written for Moto Guzzi dealers and qualified mechanics and assumes baseline mechanical knowledge; the owner's booklet handles operation, pre-ride checks, scheduled maintenance, and simple repairs.

• Engine repair coverage runs from complete power-unit removal and installation through flywheel, twin-disc dry clutch, cylinder heads and valves, timing chain and cam timing, pistons and cylinders, crankshaft and connecting rods, oil pump, oil sump, alternator, and starter work.

• Gearbox and shaft-drive procedures include transmission removal and internal disassembly, primary, secondary, and clutch shaft service, selector drum and fork inspection, reassembly, swingarm and universal-joint work, and bevel-drive, pinion, axle, seal, and final-drive casing repair and troubleshooting.

• Magneti Marelli IAW 5AM fuel-injection diagnostics cover throttle-body removal, cylinder synchronization, CO adjustment, Axone 2000 self-diagnosis, ECU parameters, device status and activation, stored-error handling, and adjustable parameters.

• Electrical-system material provides component locations, a general wiring diagram, ECU and dashboard pin assignments, charging and starter tests, fuse and lamp data, sensor and coil test specifications, immobilizer and instrument-panel error charts, and diagnostic connector locations.

• Chassis and suspension service covers fork-leg and wheel removal, fork disassembly, inspection, oil filling, steering-bearing adjustment, rear-shock removal, brake caliper and pad service, and removal of the exhaust, air box, fuel tank, and battery.

• Fifty-three numbered exploded-view parts plates supply OEM codes and quantities for assemblies including the gearbox, bevel drive, swingarm, crankcase, cylinder heads and valves, timing system, clutch, throttle body, electrical system, and factory tools.

Factory Repair Detail

The repair sections carry component-specific torque tables, approved-product and fluid charts, valve-clearance data, cylinder-to-piston and crankshaft-to-bearing limits, transmission-shaft runout checks, clutch spring specifications, fork oil data, and electrical resistance and output values. Inspection criteria are included for gears, shafts, selector forks, clutch parts, valves and guides, connecting rods, fork components, universal joints, bearings, seals, and final-drive components.

Factory tool callouts identify the 05.90.25.30 gearbox support, 12.91.18.01 flywheel/starter-ring gear locking tool, 30.90.65.10 clutch fitting tool, and 10.90.72.00 valve removal/refitting tool, along with seal drivers, a piston-ring clamp, timing dial equipment, a pinion ring-nut wrench, and bevel-gear support tooling. Named visual references include the gearbox exploded diagram, general wiring diagram and electrical component-location sheets, ECU and dashboard connector pinouts, fuel-supply circuit diagram, front-fork exploded diagram, and final-drive troubleshooting charts.

Controls, Maintenance, and Parts Identification

The owner's booklet explains the digital LCD dashboard, TRIP 1/TRIP 2 data, current fuel consumption, chronometer storage, clock and backlight settings, temperature and time formats, immobilizer LED setting, and five display languages. It also distinguishes high- and low-priority alerts, explains the service-threshold display, and covers pre-ride checks, suspension settings, engine, gearbox, and final-drive oil service, outer spark plugs, brake and clutch fluid checks, battery charging, fuses, bulbs, brake-pad inspection, storage, and the scheduled maintenance chart.

The parts catalog pairs each exploded plate with item descriptions, quantities, and ordering codes, making it useful for confirming assembly order and identifying repair parts before disassembly. Coverage is specific to the 2007 Bellagio 940 configuration shown in the catalog.

Factory Cautions and Scope

The manual warns that reversing the rocker supports or cylinder-base gasket can compromise lubrication, while incorrect timing-chain shim placement can allow the chain to wear the crankcase. It also cautions against pulling electrical connectors by their cables because this can irreparably damage both the connector and wiring harness.

Securely support the motorcycle for engine, wheel, fork, swingarm, and final-drive work, and follow the factory precautions for fuel, brake and clutch fluid, battery electrolyte, hot exhaust components, and pressurized fork oil. The owner-level booklet is limited to operation, routine maintenance, and simple repair tasks; the Service Station Manual supplies the deeper mechanical and diagnostic procedures. Several reassembly instructions refer back to the removal sequence in reverse and assume technician judgment, while the braking chapter is focused on caliper and pad removal rather than hydraulic-component overhaul.
