Fiat-Hitachi FD175 Common Problems This Manual Covers
Fiat-Hitachi FD 175 steering pulls hard or feels inconsistent, especially when turning on slopes
Inspect the steering clutch and brake troubleshooting chart on page 316 for oversteering or no-brake symptoms. Check the brake actuating spring on page 409; free length should read 425 mm and force to compress to 275 mm should fall between 668 and 738 daN. Replace worn brake bands and readjust linkage before returning to slope work.
Manual Section: Steering Clutches & Brakes - Troubleshooting p. 316Loss of power or inability to hold blade load under heavy digging conditions
Verify the hydraulic pump on page 473 is the correct Sundstrand Hydratec TAP 60-200/85S unit rated for 85 L/min at 1000 rpm no-load. Trace the hydraulic schematic and test selector valve flow. If output falls below spec, pull the pump per the repair procedures beginning on page 427 and check the gear-to-bushing clearance for wear.
Manual Section: Hdraulic System p. 427Engine runs hot and coolant level keeps dropping during extended operation
Check radiator coolant level per the Operations to Be Performed When Required section on page 65 and top off if low. Inspect the alternator/fan belt tension on page 127; a new belt should deflect under 60 to 80 N of force. Flush the radiator core of debris and replace any cracked or swollen coolant hoses before restarting.
Manual Section: Operations to Be Performed When Required p. 65Blade lift and dump cycles feel sluggish or delayed under load
Pull the dozer lift cylinder per the repair procedures on page 427 and inspect the head O-rings for swelling or hardening. Torque the cylinder head to cylinder tube fasteners on page 474 to 162 to 178 daNm (1195 to 1313 ft lbs) on reassembly. Bleed trapped air from the lines and confirm smooth lift and dump cycles before returning to service.
Manual Section: Hdraulic System p. 474Machine creeps forward or backward when transmission is shifted to neutral
Reference the transmission troubleshooting procedures for machine-creep and powershift lever complaints; check clutch pack pressure and the lube pump for blockage. If a clutch fails to fully release, inspect the modulating valve and clutch packs per the transmission repair section (pages 129 to 221), then verify the machine holds in neutral before returning it to work.
Frequently Asked Questions
How to reset Fiat Hitachi FD175 error codes?
The manual does not describe a specific procedure to 'reset' error codes. When the general fault indicator (k) flashes, the recommended actions are to stop the machine, turn off the engine, turn off the master switch, and take necessary actions to eliminate the fault. If the fault persists, contact an authorized Service Center. p. 22
What are the torque specifications for FD175 blade bolts?
The dozer blade fastening nuts should be tightened to a torque of 49 + 53 daNm. This specification is found in the section detailing dozer assembly. p. 467
How to reset steering calibration on FD175?
The manual does not provide an explicit procedure for resetting steering calibration. However, it mentions that 'Automatic adjustment is blocked' can be a probable cause for steering issues, suggesting that there is an automatic adjustment mechanism. p. 316
What do FD175 error codes mean?
The Electronic Data Monitor (E.D.M.) signals various conditions. For example, 'g. Battery charge indicator' glowing indicates a malfunction of the battery recharging system, and 'h. Engine coolant high temperature indicator' signals overheating of the coolant. p. 21
