Ducati 748 & 916 Workshop Manual, 1994–2003

Covers Ducati 748 STR., 748 S.P., 748 BIP., 916 STR., 916 Senna (916 S), 916 S.P., and 916 BIP. Includes variant-specific engine, transmission, suspension, fuel-injection, and electrical information. Unless an exception is stated, operations and specifications apply across the covered versions.

Printable PDF, Languages and Chapter Navigation

Search, bookmarks and wiring detail: PDF text search is not available. Embedded German-language chapter bookmarks are partly usable: chapter entries provide navigation, while several parent entries return to the first page. Small wiring labels require zooming, and some dense wire-color markings remain difficult to read.

One printable, 484-page PDF with parallel Italian, English, French, German, and Spanish workshop text. The total includes nine pages of front matter and the chapter dividers.

Desmodromic Engine, Injection and Chassis Service

The following selected workshop topics show the manual’s repair coverage. Further material includes headlamp adjustment and speedometer-drive service.

• Engine overhaul: Step-by-step procedures for engine removal, disassembly, inspection, and reassembly, including crankcases, crankshaft, connecting rods, cylinders, pistons, and Desmodromic cylinder heads.

• Valve gear and maintenance: Valve-clearance adjustment, timing-belt tension checks, valve-timing verification, scheduled servicing, oil and filter changes, and chain adjustment.

• Injection and ignition diagnosis: Separate I.A.W. P8 and I.A.W. 1.6 M check-lamp procedures, error-code tables, sensor and actuator checks, throttle-body synchronization, and CO adjustment.

• Suspension and steering: Showa GD 051 fork overhaul, STRADA/BIP. Showa rear-shock service, swingarm and linkage work, and steering-bearing replacement.

• Brakes, clutch and cooling: Disc and pad inspection, brake and hydraulic-clutch fluid draining and bleeding, coolant replacement, and radiator and hose checks.

• Electrical reference: ’94 and ’95 wiring diagrams, charging-system tests, connector assignments, switch and relay checks, wire-color codes, harness-routing views, and electrical test specifications.

Written for Ducati workshop personnel, this publication supplements a mechanic’s professional training and assumes access to the specified measuring equipment and special tools.

Workshop Planning and Internal Engine Repair

The dismantling-sequence flowcharts help plan access to the component being repaired. General operations cover the fairing and body panels, seat, battery-box mount, fuel tank, airbox and filter housings, exhaust, rear brake master-cylinder mount, breather and auxiliary expansion tanks, electrical connections, shock linkage, final-drive chain, throttle body, and rear-cylinder intake manifold before engine removal.

Inspection and overhaul: The engine chapters provide checks for piston rings, connecting-rod and big-end bearings, crankshaft journals and crankpins, valve guides and seats, opening and closing rockers, camshafts, camshaft supports, bearings, and oil seals. Lubrication-system material includes the oil circuit, oil pump, oil cooler, and coolant-pump assembly.

Transmission and clutch: Internal repair extends to gearbox shafts and gears, selector drum and forks, shaft shimming, primary drive, clutch plates, springs, and rubber cush-drive components. Separate S.P. and STRADA/S/BIP. data address connecting-rod fasteners, crankcase sealing, and transmission shimming.

Reassembly covers the cylinder/piston/head groups, timing drive, flywheel, belt rollers, and timing and rpm sensors. Crankcase assembly checks identify the required seating of transmission-bearing inner races. The manual also warns that reused self-locking timing-pulley ring nuts can loosen and cause severe engine damage.

Special tools and reference data: Timing-belt tension gauge 88765.0999 is listed alongside dedicated P8 and 1.6 M pick-up-height gauges, a TDC gauge, camshaft-timing tools, valve-guide and valve-seat tools, bearing installers, a rocker-shaft puller, and clutch holding tools. Reference tables supply torque and staged-tightening data, fits, clearances, wear limits, capacities, and lubricant specifications.

Fuel Injection, Fault Codes and Throttle-Body Setup

The Weber Marelli chapter explains the fuel pump, injectors, pressure regulator, intake circuit, absolute-pressure sensor, air- and coolant-temperature sensors, throttle-position potentiometer, coils, power modules, and timing pick-ups. It describes normal running, starting, acceleration, and deceleration control.

Diagnostic limits: Check-lamp tables distinguish the P8 and 1.6 M systems, and the 1.6 M section includes stored-code clearing. The P8 check lamp does not identify injector or ignition-actuator faults; sensors stuck at a plausible output can also escape check-lamp detection. Separate component tests and wiring checks support further fault tracing.

Throttle-body adjustment uses voltage measurements, intake-vacuum balancing, and exhaust-gas analysis. The chapter presents a racing-oriented CO setting rather than a road-emissions calibration.

ECU handling instructions specify a key-off waiting period before disconnecting the 1.6 M connector and dedicated EPROM extraction and installation tools. The fuel-filter procedure also warns that excessive compressed air can damage the fuel-pump suction screen.

Electrical Diagrams and Circuit Testing

Electrical chapters distinguish the 916 STR./S.P. ’94 system from ’95 models. They cover battery charging, generator and regulator checks, starter connections, solenoid and fan relays, handlebar and key switches, warning-light circuits, and cable and hydraulic-line routing.

Illustrations include the engine dismantling flowchart, Desmodromic valve-timing diagram, engine lubrication circuit, P8 and 1.6 M injection schematics, ’94 and ’95 electrical diagrams, and frame-routing views. Component legends, connector numbering, wire-color codes, sensor-response graphs, and test diagrams support circuit diagnosis.

Chassis Repair and Component-Service Limits

Wheel procedures include bearing inspection, rim checks, balancing references, sprocket work, and rear eccentric-hub removal. The manual advises against overhauling or replacing the rear hub’s internal components; its service instructions include outer-seal replacement.

The rear-shock overhaul chapter specifically covers the Showa unit on STRADA/BIP. versions, rather than every S.P. suspension unit. Swingarm and linkage procedures include bearing and seal replacement, while geometry sections explain the relationship between chain adjustment, rear ride height, and steering-head settings.

Brake and hydraulic-clutch chapters cover external service and fluid work. The manual advises against internal overhaul of brake calipers, brake master cylinders, and the hydraulic-clutch master cylinder. Cooling coverage includes the circuit layout, coolant level, radiator condition, hoses, and connecting unions.

Because the publication addresses pressurized fuel, hot coolant, brake and clutch hydraulics, gas-charged suspension, engine removal, electrical testing, and rotating drivetrain parts, stable support, ventilation, fire precautions, electrical isolation, and suitable eye and skin protection are required for workshop use.

Clutch Wear Limits: Selected Inspection Data

The clutch inspection section specifies a minimum driving-plate thickness of 2.8 mm for STRADA/S/BIP. versions and 2.3 mm for S.P. versions, alongside checks for burning and distortion.

Clutch-spring inspection gives 36.5 mm as the minimum free length. These limits accompany the component inspection material used to assess clutch wear.
