2007–2015 Aprilia SL 750 Shiver OEM Service & Repair Manual (P/N 854146)

Aprilia’s Service Station Manual 854146 covers maintenance, repair, and electrical diagnosis for the 2007–2015 Aprilia SL 750 Shiver with the M551M engine.

• Engine repair: Engine removal and installation, cylinder-head and valve inspection, timing-chain replacement, camshaft timing, and crankcase disassembly.

• Clutch and gearbox: Multi-disc wet-clutch disassembly, plate and spring inspection, gearbox-shaft removal, and gear-selector checks.

• Ride by Wire: Marelli 5DM ECU and throttle-control diagnosis, throttle self-learning, grip-sensor autodetection, and intake-pressure fault tracing.

• Electrical troubleshooting: EFI and no-start diagnostic routines, CAN communication checks, wiring diagrams, connector pin-out charts, and component-location views.

• Suspension and brakes: Upside-down fork overhaul, steering-bearing adjustment, wheel-bearing checks, rear shock removal, brake-pad replacement, and hydraulic brake bleeding.

• Cooling and lubrication: Water-pump overhaul, radiator removal, coolant replacement, oil-pump inspection, and related service specifications.

This manual is suited to technicians familiar with internal engine work and electronic throttle systems; its diagnostic procedures use AXONE, and major mechanical work requires dedicated service tools.

Engine Overhaul and Maintenance

The maintenance section provides service schedules, fluid specifications, and valve-clearance adjustment procedures. Internal engine coverage extends to piston and cylinder inspection, crankshaft removal, bearing selection, and oil-pump service.

Component matching: Piston-to-cylinder grades and color-coded bearing-shell selection tables help identify the correct mating components during an overhaul. The gearbox-shaft diagram and clutch exploded view show the washers, circlips, spacers, and disc arrangements used during reassembly.

Camshaft handling: The timing section identifies left-hand threaded nuts on both rear-cylinder camshafts and warns that final tightening with the shafts installed can permanently damage the cylinder head. Tool references include timing pin 020719Y, timing tool 020720Y, and clutch-bell locking tool 9100896.

Use secure engine-support equipment during removal and follow the manual’s precautions for hazardous fluids and hot components.

Ride by Wire and Electrical Diagnosis

Component-specific fault codes link AXONE readings to connector, continuity, insulation, and supply checks. This helps distinguish wiring faults from sensor faults before replacing components.

The Marelli ECU, EFI throttle control unit, and instrument panel have separate pin-out references. CAN-line troubleshooting addresses communication between these modules, while sensor sections cover the throttle grip, intake pressure, temperature, lambda probe, and bank-angle sensor.

Replacement and initialization: ECU activation, throttle self-learning, and throttle-grip autodetection are documented. The grip-sensor connectors look alike but have different assignments identified by their markings. The throttle bodies are replacement assemblies; their internal motors and position sensors are not covered as rebuildable components.

The General wiring diagram includes a component key and wire-color legend. Relay-location references connect diagram numbers with installed positions and wire colors, supported by main and auxiliary fuse assignments and harness-routing illustrations.

Suspension and Brake Service

Fork overhaul distinguishes the different left- and right-side cartridges and covers bushing inspection, seal replacement, pumping-element bleeding, and oil filling. The front-fork diagram identifies the internal parts and their arrangement.

Chassis procedures include swingarm removal, steering-bearing preload adjustment, and drive-chain inspection. Brake coverage includes the radial front calipers, pad replacement, and separate front and rear hydraulic bleeding procedures.

Cooling System and Component Access

The cooling-circuit diagram shows the radiator, expansion tank, pump, and three-way thermostat connections. Water-pump overhaul includes rotor-shaft and seal installation, with hydraulic-press requirements identified.

Bodywork sections explain access through the fuel tank, airbox, side panels, and tail assembly. Exhaust-manifold and lambda-probe removal are also covered.

A Sample of Valve-Train and Fork Service Data

These figures are a small selection of the adjustment and assembly specifications included in the manual.

Valve-clearance specifications are 0.11–0.18 mm for the intake and 0.16–0.23 mm for the exhaust. For the M6 cam-cap-to-head screws, the timing section lists pre-tightening at 4.90–6.86 Nm and final tightening at 9.81–12.75 Nm.

The fork-refill section specifies 535 cm³ of oil per leg, alongside oil-level measurement conditions and pumping-element bleeding instructions.

Text Search, Diagram Detail, and PDF Contents

Search and drawing readability: Text search works across the service chapters, but labels embedded in diagram images are not searchable. There are no embedded PDF bookmarks. Small labels in the general wiring diagram remain partly unreadable when enlarged; the separate ECU connector views are clearer.

Delivered as one printable, English-language 303-page PDF. The total includes six front-matter pages, including two blank pages, plus seven additional pages containing only running headers and footers.
