Need the factory numbers for your Fiatallis FD80? This 387-page Crawler Dozer Operation and Maintenance Instruction Manual PDF (OEM #604.03.394.00) is the same book Fiatallis put in the dealer's hands. You get the complete electrical system diagram with fuse locations and the MC7 microprocessor, hydraulic schematics for the dozer equipment, and page after page of exploded views covering the final drives, sprocket, and undercarriage. A full maintenance section with greasing charts, plus troubleshooting trees for engine and travel system faults, rounds out the operator side. Confirm the engine's 35.8 daNm net torque at 1400 rev/min, then check final drive output against the 3500 daNm maximum before you button it up. Your dozer is down and the dealer is closed. Bookmarked PDF: pull it up on your phone in the shop and get back to work.

FiatAllis FD80 Common Problems This Manual Covers
Engine turns over slowly in cold mornings and will not start without a boost
Load-test the battery first; the machine runs a single 180 Ah battery, listed with the specs on page 54. Clean and tighten both battery terminals and the engine ground strap, then check cranking speed again. If cranking is strong but the engine still won't fire, work through the engine troubleshooting chart on page 140.
Manual Section: Engine Troubles (General) p. 140Frequently Asked Questions
How do you fix fiatallis FD80 won't move, engine runs and blade works but travel joystick does nothing?
Check the travel system troubleshooting chart on page 140 first. Test hydrostatic drive pressure; the transmission should develop 420 bar (42000 kPa) operating pressure. If pressure is good, inspect the joystick linkage for disconnection and verify lever effort stays under the 8 daNm maximum; a detached linkage feels completely dead at the stick. p. 140
How do you fix machine will not steer left or right, both steering levers feel normal?
Test the brake release circuit before condemning the clutches: minimum release pressure is 13 bar (1300 kPa) and maximum operating pressure is 50 bar (5000 kPa), both on page 308. If pressures check out, pull the steering clutch covers and inspect friction plates for wear and glazing, then replace hardened seals. p. 308
How do you fix blade tilt and lift bleed off at idle, pressure returns only at high throttle?
Check hydraulic oil level first; the system holds 80 l (21.1 gal) per page 55. Inspect the suction line and pump inlet fittings for air leaks, then cut open the return filter and look for metal shavings. Weak functions at idle that recover with throttle usually mean internal pump wear; plan an overhaul. p. 331
How do you fix right track loses drive under load and steering clutch slips during turns?
Inspect the right steering clutch friction plates and seals; a leaking seal soaks the plates and kills drive under load. Verify holding capability against the 60 daNm braking torque spec on page 308. If the final drive must come off for access, support it properly: the assembly weighs 350 kg (771.6 pounds). p. 270
