1989–1995 Ferrari 348 / Mondial t Factory Workshop Manual (P/N 95990883)

• Reproduces the Ferrari Servizio Assistenza Tecnica 348 workshop manual, with 348 tb and ts references. Fuel and ignition coverage is divided between Bosch Motronic M2.5 for 1989–1993 and a 1994 Motronic M2.7 diagnosis-sheet insert expressly marked for the Mondial t–348 with the F119 D.040 engine.
• Documents major F119 engine repair work, including crankcase and Nikasil liner inspection, crankshaft and bearing checks, piston and connecting-rod assembly, cylinder-head and valve service, tappet-shim adjustment, cam timing, timing-belt installation, engine assembly, and hydraulic leak testing.
• Covers both clutch configurations and the transaxle: AP Racing dry twin-plate and Valeo dry single-plate units, the Voith damping flywheel, hydraulic release and bleeding, clutch fitting checks, gearbox removal and overhaul, synchronizers, oil pump, differential, selector shafts, and axle shafts.
• Provides chassis repair and setup procedures for suspension inspection, front and rear wheel-bearing replacement, third-generation bearing arrangements, damper adjustment, wheel geometry, brakes, and Teves ABS MK II hydraulic and electrical fault isolation.
• Includes factory diagnostic material for Motronic sensor and actuator signals, ABS self-diagnosis and interconnector testing, plus Ferrari Tester diagnosis of the electronic climate-control system.
• A 465-page PDF in Italian, English, French, and German, with wiring diagrams, torque data, clearances, wear limits, capacities, electrical test values, maintenance schedules, and numbered special-tool references.

348 System Coverage

This workshop publication moves from vehicle identification and capacities through the engine, clutch and transaxle, steering, suspension, brakes, driving controls, air conditioning, electrical equipment, and scheduled maintenance. The main chapters are organized around the Ferrari 348. The M2.7 diagnosis insert specifically identifies Mondial t–348 applications, rather than extending Mondial coverage across every mechanical section.

F119 Engine, Clutch, and Transaxle

The engine chapter distinguishes the F119 D catalyst and non-catalyst configurations from the U.S.-version F119 G 040. Its repair coverage includes liner classification and fit, main-bearing alignment, crankshaft journal and end-float inspection, connecting-rod weight matching, valve-seat and guide work, camshaft-seat machining, valve-clearance setup, cam timing, belt installation, and final engine assembly. Separate lubrication, crankcase-emission, and cooling chapters provide circuit layouts, pump checks, test specifications, and component service data.

Ferrari tool numbers are tied to the jobs they support. Examples include the AV 2023 engine stand with AM 104116 bracket, AS 4736 main-bearing alignment bar, AV 1639 liner puller, AS 6236 liner hold-down tools, AV 1499 valve tool, AS 9560/AS 9560A shim tools, and CS 7148 shim-measuring fixture.

The clutch section addresses both factory arrangements, along with installation checks, hydraulic release-system bleeding, and pedal setup. The transaxle material proceeds through removal, internal gearbox repair, synchronizer and oil-pump inspection, differential work, and assembly of the selector, clutch, transmission, and axle shafts.

Teves ABS, Chassis, and Electrical Diagnosis

The Teves ABS MK II section goes well past a system overview. It covers the main and auxiliary hydraulic units, pump and accumulator, wheel sensors, ECU operation, self-diagnosis, electrical checks through the interconnector, and solenoid-valve testing. It also distinguishes ECU numbers 131325 and 148838 and hydraulic units 139234 and 148839, an important detail when selecting repair information or replacement parts.

Suspension coverage includes arm and bushing inspection, Hyperblock and stabilizer checks, front and rear hub-bearing replacement, third-generation bearing layouts, damper adjustment, spring identification, wheel alignment, and balancing. The steering chapter is much narrower: it provides rack-and-pinion specifications and maintenance information, not a full steering-rack overhaul.

The air-conditioning chapter covers the original R12 electronic climate system, functional checks, maintenance, and Ferrari Tester diagnosis. It describes stored-fault reading, guided diagnosis, live-parameter display, data capture, on-board checks, and active tests of the flap motors, heater valve, blower, compressor clutch, and heater-water pump. Electrical schematics cover the alternator and starter, Motronic M2.5 with and without catalysts, exterior lighting and accessories, power windows and door locks, climate and engine cooling, and ABS.

Representative illustrations include transverse and longitudinal engine sections, the timing-gear diagram, lubrication-system layout, Teves ABS hydraulic layout, and Motronic M2.7 sensor charts with the associated wiring schematic.

Repair Cautions Called Out in the Manual

The liner chapter warns that the Nikasil running surfaces must not be ground because machining removes the hardened coating; it also requires the color-classified pistons and liners to remain correctly matched. The Voith flywheel and vibration damper are treated as a balanced assembly and are not to be separated.

The Teves hydraulic unit must be depressurized before its circuit is opened, and the air-conditioning chapter involves refrigerant service. Both repair areas are intended for trained handling with the specified equipment and safety procedures.
