1995 Fiatallis / Fiat-Hitachi FX250 Excavator Service, Parts, Operation and Maintenance Manuals (P/N 60406757)

The 1995 Fiatallis FX250 hydraulic excavator collection covers Monobloc and Triple Articulation configurations. It combines the Operation and Maintenance Instruction Manual, Publication No. 60417028, the Service Manual, Print No. 60406757, and a Fiat-Hitachi parts catalog.

Supplied as a single 1,307-page PDF containing three publications. The engine-overhaul section and several closing sections of the operating manual are not included.

• Hydraulic repair: Main-pump removal, internal inspection, bearing adjustment, regulator overhaul, and control-valve and pilot-valve disassembly and assembly.

• Travel and swing drives: Hydrostatic travel-motor repair, planetary reduction-unit rebuilding, swing-motor service, center-joint overhaul, and undercarriage inspection limits.

• Front-end attachments: Boom, arm, bucket, and positioning-cylinder removal and installation, cylinder seal replacement, and pin-and-bushing clearance specifications.

• Electrical diagnosis: Electronic Data Monitor checks, E-P control troubleshooting, wiring diagrams, connector layouts, and auto-idle device adjustment.

• Performance testing: Pump-flow measurements, relief-valve checks, motor leakage tests, cylinder-drift measurements, and travel and swing performance standards.

• Routine maintenance: Fuel-system bleeding, cooling-system flushing, track-tension adjustment, bucket-linkage shimming, filter replacement, and scheduled lubrication.

• Parts identification: Exploded assembly views, part numbers, kit references, optional-equipment listings, and modification tables with serial-number applicability.

Qualified operators can use the operating guidance, while the service manual is written for technician training and as a reference for experienced service technicians.

Model Variants and Parts Selection

The parts catalog identifies the one-piece boom as product code 26SM, version 02, and Triple Articulation as 26ST, version 01. Its engine listings distinguish the Cummins 6BTA 5.9C through S/N 123 from the 6BTA 5.9 ELITE from S/N 124, using modification codes C3700 and D3700.

These distinctions help match replacement parts to the installed engine before ordering. Separate illustrations cover the Monobloc boom, positioning arm, variant-specific piping, and optional hydraulic-hammer equipment.

Machine Systems and Maintenance

The ETS Electronic Total Control System description covers E-P Computer Aided Engine-Pump Control, OHS Optimum Hydraulic System, and FPS Fuel Saving Pump System. Operating guidance explains bucket, swing, and track controls alongside the Electronic Data Monitor's warning lamps and level checks.

Daily walk-around inspections and pre-shift checks accompany guidance on inclines, overhead power lines, and confined workspaces. FOPS/FGPS cab protection, instrument-panel illustrations, lifting-capacity charts, and Monobloc/Triple Articulation digging-data views are included.

Service references distinguish swing-drive oil-level checks from oil changes. They also cover hydraulic-pump reduction-unit servicing and return-filter components, including the spring, valve, and O-ring. Thread sizes and tightening torques are provided for bull-gear, hydraulic-tank, and other mounting fasteners.

Hydraulic and Undercarriage Repair

Pump overhaul includes internal clearance measurements, wear limits, and bearing-preload adjustment. The special-tool list identifies bearing holder 75298340 and rotor-positioning guide 75298332.

Control-valve inspection explains that spools are selectively fitted to their housing bores and are not supplied separately for field replacement. The hydraulic maintenance instructions also warn that an unprimed pump can seize at the next start.

Track-chain, idler, roller, and swing-bearing sections extend beyond tension adjustment to removal, installation, and wear assessment. Swing-bearing installation addresses the orientation of the races' soft zones to avoid concentrating load on those areas.

Fault Diagnosis and Circuit Diagrams

Symptom-based troubleshooting covers weak digging power, cylinder drift, loss of swing, slow travel, and uneven tracking. The electrical section includes volt-ohm meter checks and MECHATRO CHECKER procedures for controller inputs and outputs, helping distinguish wiring, sensor, and control faults before repair.

The reference drawings include main hydraulic circuits, the Positioner Control Circuit for Triple Articulation, electrical wiring and connector diagrams, and a travel-reduction-unit cutaway. Pump pressure/flow charts support the component performance tests.

Follow the manual's precautions for raised attachments, stored hydraulic pressure, and electrical isolation before service work.

Engine and Operating-Manual Coverage Limits

Engine material includes specifications, routine maintenance, and performance checks. Section 11, Engine, appears in the service contents but is absent from this PDF; internal engine overhaul requires separate documentation.

The operating manual ends at printed page 78. Its listed hydraulic-line and coupling assembly rules, fluid-capacity table, and hydraulic-breaker section are not included.

File Format and Readability

The total includes 105 operating-manual pages, 500 parts-catalog pages, 701 service-manual pages, and one DealerNation introductory page. Covers, indexes, and inserted schematic sheets are already included in those counts. English operating and service text is accompanied by multilingual parts-catalog material.

Text search: No embedded searchable text or OCR layer.

Navigation: Bookmarks cover the three publications and major service sections. Three “MAIN MENU” entries point to an external menu file that is not included.

Diagram readability: Zooming is needed for small labels; some fine wire codes remain difficult to read in dense electrical schematics.
