Piaggio Beverly Cruiser 500/500ie – 2005 Service Manual Set (P/N 664646-664653)

The main workshop manual covers vehicle service and repair. The supplement adds in-vehicle water-pump integral-seal replacement, while the additional wiring sheet provides the overall electrical circuit.

Match the chassis and engine prefixes before selecting this set; the repair coverage should not be extended to every Beverly 500 variant.

PDF Search, Bookmarks, and Diagram Legibility

Text and diagram access: The service text supports PDF text search, but many labels within embedded diagrams do not. Embedded bookmarks cover chapters and procedures, although several chapter links return to the cover. Some small labels in the embedded electrical schematics remain difficult to read when enlarged; the additional wiring sheet has labels that are readable with zooming.

The ZIP contains one printable, 373-page PDF: the 364-page main manual, including its cover, front matter, and blank page, plus the eight-page bilingual supplement and one-page wiring sheet. These nine supplementary pages are included in the total.

Engine Overhaul, CVT Service, and MIU Diagnosis

The following selected coverage highlights outline the major workshop areas rather than reproduce the full contents. Additional topics include headlight adjustment and turn-signal circuit checks.

• Engine repair: Step-by-step procedures for engine removal and installation, cylinder-head and valve service, timing-system setup, crankcase splitting, crankshaft and countershaft work, and oil-pump overhaul.

• CVT and final drive: Variator and drive-pulley service, belt and roller inspection, driven-pulley and clutch disassembly, transmission-cover bearing replacement, and final-reduction overhaul.

• MIU injection and immobilizer: Diagnostic-tester routines, fuel-pump and injector checks, ignition verification, sensor and lambda-probe testing, TPS reset, key programming, and immobilizer fault diagnosis.

• Suspension and steering: Front-wheel bearing replacement, fork overhaul, steering-head bearing service, swing-arm bearing work, shock-absorber replacement, and center- and side-stand service.

• Brakes and chassis access: Front and rear caliper overhaul, pad and disc inspection, combined-brake bleeding, master-cylinder removal, and body-panel and fuel-tank removal.

• Cooling-system repair: Fan diagnosis, sealing checks, coolant replacement and venting, thermostat testing, water-pump inspection, and integral-seal replacement using the included supplement.

• Workshop reference material: Component-specific torque tables, capacities, assembly clearances, wear limits, electrical test specifications, fault charts, wiring diagrams, coded special tools, pre-delivery checks, and operation-code tables.

Written for Piaggio-Gilera dealer workshops, the manual assumes knowledge of mechanical principles and vehicle repair procedures, along with access to the specified equipment and special tools.

Engine Internals and Lubrication

The SOHC, dual-spark engine material extends beyond scheduled maintenance. Cylinder-head work includes valve and guide inspection, camshaft and rocker-arm checks, timing-chain installation, and piston, ring, and cylinder inspection. Engine removal also addresses exhaust and lambda-probe disconnection.

Crankcase procedures cover splitting and rejoining the case halves, bearing and bushing selection, crankshaft alignment, axial-clearance checks, countershaft timing, and oil-seal installation. Piston-position measurement and base-gasket selection help restore the correct compression-ratio category during reassembly.

Flywheel and starter-system sections include freewheel and torque-limiter inspection, starter electrical tests, and component replacement. Lubrication material combines oil-pump inspection with pressure-based fault charts for low pressure, leakage, and excessive oil consumption.

The manual cautions against ceramic-magnet damage from stator/rotor contact, main-bearing damage from the crankshaft’s threaded ends, and disrupted lubrication from incorrect oil-seal positioning.

CVT, Clutch, and Reduction Gears

The transmission procedures distinguish variator roller and guide-shoe wear from driven-pulley bearing, seal, and clutch faults. Clutch inspection includes friction material and spring checks, with final assembly using the specified fixture.

Final-reduction coverage adds wheel-axle, countershaft, and driven-pulley shaft inspection, hub-bearing and oil-seal replacement, and hub-cover repair.

Injection, Ignition, and Electrical Fault Tracing

MIU/EMS material supplies terminal assignments, diagnostic-tester connections, and symptom-based fault charts for starting difficulty, unstable idle, backfiring, and poor performance. Fuel-system checks distinguish pump supply, pressure and flow, injector circuitry, delivery, and leakage.

Ignition-coil and rpm-sensor tests, coolant-sensor resistance checks, lambda-probe diagnosis, and ignition-advance verification support fault isolation before components are replaced. The throttle-body section explains factory pre-calibration and the conditions and restrictions for TPS resetting.

Immobilizer coverage includes key storage, programming, LED codes, aerial and decoder checks, and control-unit replacement. A separate note addresses the MIU power-supply stabilizer fitted to an initial production lot, including its connection and diode-test checks.

The cautions also address control-unit damage from improper MIU connector handling and in-tank pump damage from start testing with insufficient fuel.

Suspension, Combined Brakes, and Cooling

Chassis procedures include fork disassembly and reassembly, steering-bearing replacement and adjustment, swing-arm bearing overhaul, and shock-absorber removal and refitting. Body sections show access through the seat, fairings, instrument panel, leg shield, ignition lock, helmet compartment, fuel tank, and radiator area.

Brake coverage distinguishes front and rear calipers, pad orientation, disc inspection, and master-cylinder removal. Combined-circuit bleeding addresses the rear caliper, regulating valve, and front-left caliper.

Cooling diagnosis covers excessive pressure, coolant loss, and oil contamination. The included MASTER-engine supplement describes water-pump integral-seal replacement without engine removal and identifies tool kit 020661Y.

The fuel circuit is pressurized, and brake and cooling-system work should follow the manual’s handling, bleeding, and final-check procedures with calibrated tools.

Workshop Tools and Circuit References

The Tooling chapter lists more than 60 coded items. Examples include the 020460Y scooter diagnosis tester, 020481Y control-unit interface wiring, 020480Y fuel-pressure check set, 020444Y driven-pulley clutch tool, 020475Y piston-position checking tool, and 020471Y countershaft timing pin.

The overall electrical schematic, front and rear wiring-installation views, ignition conceptual diagram, battery-recharge and starting diagram, EMS circuit diagram, and cooling-system circuit diagram support mechanical and electrical fault tracing. Connector layouts, component-location views, injection-load circuits, lubrication-flow diagrams, exploded service views, and fault charts connect the procedures to their related systems.

Reference tables cover cylinder/piston coupling categories, ring and valve limits, crankshaft/crankcase selection, bearing fits, suspension settings, brake limits, lubrication pressures, and electrical test values. Maintenance schedules, pre-delivery checks, and factory operation-code tables provide additional workshop references.

A Preview of Belt Wear and Sensor Test Values

Drive-belt inspection lists an overall width of 28.7 mm and a minimum width of 27.5 mm, giving the CVT section a specific wear-check reference.

For the coolant-temperature sensor, the electrical checks specify 2,500 ± 100 Ω at 20°C and 308 ± 6 Ω at 80°C. These temperature-dependent resistance values accompany the sensor’s connector and wiring checks.
