Piaggio Beverly 300 ie E3 2010–2012 Workshop & Parts Manual Set (P/N 665358(EN))

The repair manual explains diagnosis and service procedures, while the parts catalog identifies assemblies and original Piaggio component codes. Verify the chassis prefix, engine prefix, and full chassis number before ordering parts or applying a service procedure.

Searchable PDFs and Diagram Readability

Text search, bookmarks and diagrams: Both PDFs have searchable text and embedded bookmarks. Workshop bookmark navigation is partly limited: some chapter headings have no jump destination, and several subsection links land a page early. Small labels in several wiring diagrams remain faint or pixelated when enlarged; text legends and connector tables are more readable.

The ZIP download contains two unencrypted, printable PDFs totaling 399 pages, including their covers, introductory pages and indexes. Technical content is predominantly English, with some Italian introductory text and parts descriptions.

Engine Overhaul, MIU Diagnosis and Parts Identification

These selected coverage highlights are not a complete contents list. Other topics include headlight adjustment and pre-delivery inspections.

• Engine and CVT repair: Engine removal and refitting, variator and clutch disassembly, final-drive bearing service, cylinder-head repair, timing-system assembly, and internal engine inspection.

• MIU injection diagnosis: No-start, unstable-idle, poor full-throttle performance, and deceleration-backfire troubleshooting, with fuel-pressure tests, injector checks, sensor testing, active diagnosis, and TPS reset.

• Suspension, steering and brakes: Fork and wheel-hub overhaul, steering-bearing and swing-arm service, caliper/disc/pad replacement, and front and combined-rear brake bleeding.

• Cooling system: Electric-fan diagnosis, thermostat testing, radiator removal, and cooling-system bleeding, supported by a circuit diagram.

• Electrical references: Ignition, charging/starting, lighting and accessory diagrams, component locations, ground points, connector pinouts, immobilizer fault codes, and continuity tests.

• OEM parts identification: Exploded plates and an alphanumeric index connect engine, bodywork, controls, suspension, brakes, cooling, and wiring assemblies to component codes.

• Service references: Maintenance schedule, service-warning reset, torque tables, fluid specifications, wear limits, clearances, electrical test data, and coded special-tool listings.

Piaggio identifies the workshop volume as a publication for dealer and sub-dealer workshops; it assumes basic mechanical and vehicle-repair knowledge, suitable facilities, and access to the specified equipment.

Engine, CVT and Internal Rebuild Detail

The drivetrain chapters cover the liquid-cooled four-valve engine, dry centrifugal clutch, and oil-bath final reduction. CVT inspection extends to clutch-bell runout, driven-pulley bearings, rollers and drive-belt condition, alongside reduction-gear, flywheel and starter-drive service.

Step-by-step procedures cover cylinder-head and valve work, camshaft inspection, timing installation, piston and ring checks, and crankcase splitting. Crankshaft alignment, lubrication-pressure testing, and oil-pump inspection and refitting extend the coverage into internal engine repair.

Crankcase and crankshaft category matching, color-coded main-bearing selection, and cylinder base-gasket shimming guide component matching during a measured rebuild.

Injection and Immobilizer Fault Tracing

General troubleshooting tables connect engine-performance, starting, lubrication, clutch, braking, steering and suspension symptoms with component checks. The injection chapter separates fuel-pump circuit diagnosis from injector electrical and hydraulic testing.

Further fault paths address the engine-speed signal, HV coil, coolant-temperature sensor and lambda probe. Immobilizer coverage includes virgin-control-unit key storage and one-, two- and three-flash diagnostic codes.

TPS reset coverage includes initial installation and ECU replacement, with an explicit restriction against performing the reset on a used throttle body.

Circuit Diagrams and Chassis Variants

Representative references include the EMS circuit, ignition circuit, battery recharge and starting circuit, lights and turn indicators circuit, and cooling-system circuit. Connector tables provide terminal assignments and wire colors alongside component-location and ground-point views.

The brake chapter distinguishes rear wheels with an integrated hub from those with a hub independent of the wheel. Match the illustrated arrangement to the vehicle before selecting the procedure.

Parts Lookup and Workshop Equipment

The catalog includes plates for the throttle body/injector, Kayaba fork, brake plumbing, switches, ECU, lamps and main harness, alongside engine and bodywork assemblies. Finished-product entries identify factory color variants, which helps when matching painted body parts.

Specified equipment includes Diagnosis Tool 020680Y, control-unit interface wiring 020481Y, fuel-pressure check kit 020480Y, and driven-pulley clutch tool 020444Y. The listings also identify Mity-Vac pump 020329Y and engine support 005095Y.

The TIME chapter lists coded repair operations, but its duration columns are blank.

CVT and Oil-Seal Cautions

Incorrect installation of the transmission-side crankshaft oil seal can mis-tension the oil-pump drive chain and cause serious engine damage. The clutch section also warns that prying the shoes open can alter return-spring load, while excessive tool insertion beneath the driven-pulley pin collar can damage its O-ring seal.

Follow the manual's precautions for fuel handling, battery service, hot coolant, brake fluid, and engine-running ventilation.

Examples of Injection-System Test Specifications

The injector-circuit section specifies injector resistance of 14.5 Ω ±5%. Its injection-load relay check gives an energizing-coil resistance range of 40–80 Ω.

For coolant-temperature diagnosis, the sensor check lists 2,500 ±100 Ω at 20°C and 308 ±6 Ω at 80°C. These temperature-dependent reference points accompany the sensor circuit and connector checks.
