Ferrari 550 Maranello 1996–2001 Workshop Manual Set

The two volumes bring together mechanical repair data and electronic-system diagnosis in Italian, English, French, and German. Individual factory sections carry revision dates from September 1996 through December 1997.

Coverage limits: The gearbox chapter stops at D.29; pages D.30–D.43 are absent. The European electrical section lacks pages L.3–L.22, and not every wiring sheet listed in the electrical indexes is included. Sections M, Chassis and Bodywork, and N, Maintenance Schedule, are also absent.

PDF Search, Bookmarks, and Wiring Detail

Search and diagram navigation: Text search is partial, with no searchable text in Section L. Embedded bookmarks cover both volumes, although some entries have missing or inaccurate destinations. Small wiring labels require magnification; the larger circuit drawings are divided into separate page quadrants.

One printable PDF contains 455 pages, including six cover and preliminary pages.

V12 Overhaul, Drivetrain Service, and Electronic Diagnosis

These are selected contents rather than a complete contents list. Further topics include instrument warning displays and electric-seat controls.

• Engine overhaul: Crankcase and cylinder-liner inspection, crankshaft refacing, piston and connecting-rod assembly, cylinder-head work, valve gear, camshafts, timing belts, lubrication, and cooling.

• Bosch Motronic M5.2: Sensor and actuator checks, catalytic-converter protection, secondary-air injection, evaporative-emission control, idle adjustment, cylinder-bank synchronization, fuel-pressure testing, and SD-1 diagnosis.

• Clutch and gearbox: Clutch removal and fitting, hydraulic bleeding, gearbox removal, synchronizer inspection, shaft end-float checks, and initial gearbox and differential setup.

• Steering and suspension: ZF Servotronic filling and electrical checks, wheel-bearing replacement, wheel alignment, Bilstein variable-damping diagnosis, and magnesium-wheel inspection and refinishing.

• Brakes and ABS/ASR: Brake-pad replacement, caliper checks, parking-brake adjustment, hydraulic bleeding, Bosch ABS/ASR fault diagnosis, and active SD-1 tests.

• Climate control: Refrigerant recovery and charging, pressure-switch and expansion-valve checks, compressor-belt adjustment, temperature-sensor diagnosis, and Diavia control-system testing.

• Electrical and body controls: European and U.S. electrical references, battery tests, lighting service, fuses and relays, wiring diagrams, connector keys, window-control diagnosis, alarm diagnosis, and airbag-system checks.

This material is suited to professional technicians and Ferrari specialists with precision measuring equipment, SD-1 access, and a properly equipped repair shop.

Engine Inspection, Assembly, and Special Tools

Overhaul planning: Factory clearances, wear limits, torque tables, and tool references support inspection and machining decisions before reassembly. The procedures extend to connecting-rod alignment and weight matching, valve-seat and guide work, engine hydraulic testing, and final cam-timing checks.

Tool identification: The engine tables identify the STAEGER FST 50 belt-tension gauge 95970135, AV 1639 liner remover 95971639, AV 2023 engine/gearbox overhaul trolley 95972023, AV 2595 cylinder-head nut wrench 95972595, and AV 2881 valve-guide seal punch 95972881.

The manual warns that grinding the aluminum cylinder liners removes their special surface treatment; their sealing faces are also vulnerable to chipping and marking.

SD-1 Tests and Drivetrain Setup

Diagnostic depth: Motronic coverage includes ECU parameter display, stored-fault interpretation, guided checks, injector and actuator tests, buffer graphing, and an automatic test cycle. The injection chapter also describes the diagnostic reset of learned values after actuator replacement.

Suspension diagnosis distinguishes locked or incorrectly fitted actuators from missing speed signals and sensor faults. ABS/ASR coverage adds wheel-speed, solenoid-valve, pump-motor, and warning-light tests.

Gearbox setup: The supplied pages explain synchronizer contact checks, pinion preload, adjustment spacers, and ring-and-pinion contact patterns. The missing continuation prevents this file from providing the complete internal reassembly sequence or the separately indexed differential, axle-shaft, and external shift-control chapters.

The shared clutch and brake reservoir receives a specific warning: mineral hydraulic fluid can irreparably damage the brake-system rubber seals.

Wiring References, Climate Control, and Wheel Care

Illustrations and circuits: Examples include engine cross-sections and longitudinal sections, the timing-control diagram, the Motronic M5.2 injection-ignition layout, the gearbox assembly view, the variable-setting suspension diagram, and ABS/ASR hydraulic and wiring diagrams.

The electrical material includes starting and charging circuit references, battery current-draw and load tests, lighting procedures, and component/connector keys. Supplied drawings cover injection circuits, front and rear harness locations, dashboard and tunnel wiring, engine services and air-conditioning connections, lighting, and the alarm system.

Climate and wheel service: Diavia diagnosis relates control inputs to heater-valve, compressor, fan, and sensor operation. The wheel material distinguishes corrosion and damage assessment from permitted magnesium-rim refinishing work.

Fuel-system, brake, refrigerant, airbag, and vehicle-lifting work requires the specified isolation, pressure-handling, and workshop equipment. Follow the manual’s safety notes and applicable Ferrari tool requirements.

Examples of Liner and Crankshaft Inspection Data

For cylinder-liner installation checks, the manual specifies protrusion above the crankcase of 0.03–0.08 mm and requires equal protrusion across each cylinder bank.

The crankshaft inspection procedure gives an end-float range of 0.100–0.289 mm, measured with the bearing halves and thrust shims in place. These examples show the dimensional inspection data accompanying the engine assembly procedures.
