![FiatAllis FL175 Repair Manual + Operation Maintenance Manual [Crawler Loader]](https://youfixthis.com/wp-content/uploads/2014/12/2019-12-01_15-31-51-300x300.jpg)
This 779-page FiatAllis FL145 Operation and Maintenance Instruction Manual, Service Manual (OEM #604.00.516, 73156192) covers the crawler loader from cab controls down to final drives. You get wiring diagrams for the full electrical system, hydraulic schematics covering the tank, pump, valve, and boom/bucket/ripper cylinders, plus a dedicated troubleshooting section for engine, transmission, and steering clutch faults. Inside you'll also find every maintenance interval laid out (250, 500, 1,000, and 2,000-hour services) alongside torque charts for bolts, screws, and nuts by material strength class. The attachment hydraulic system spec calls for oil filtered through two full-flow filters (metal gauze on suction, paper on return), and steering clutches run multi-disc oil-bath with hydraulic release control, exactly as your machine left the factory. No more guessing at fluid grades or chasing electrical gremlins with a test light. Bookmarked and searchable: jump straight to the section you need and get back to running the machine.

Quick Reference Specifications
| Specification | Value | Page |
|---|---|---|
| Hydraulic system performance loss (slow response or complete failure) | If controls or other hydraulic systems feel spongy have the machine checked for air in the systems. Presence of air in these systems could cause improper control and result in an accident. See the Operation and Maintenance Instruction Manual for corrective procedures. | p. 3 |

FiatAllis FL145 Common Problems This Manual Covers
FiatAllis FL145 machine will not move forward or backward despite engine running well
Test the transmission main pressure using a calibrated gauge. Verify the pressure reads 16.5-17.5 bar on page 147. If the pressure drops, inspect the converter and transmission pressure pump suction line. Clean the replaceable steel mesh elements and check the magnetic plug.
Manual Section: TransmissionLoader will not turn left or right and steering clutch does not modulate
Inspect the multi-disc oil-bath steering clutches for wear. Measure the bore for the release plunger clearance, ensuring it falls within 0.443-0.123 as specified on page 389. Torque the clutch pack assembly capscrews to 13 daNm and the hub to bevel shaft capscrew to 67 daNm.
Manual Section: Bevel Gear, Steering and Brakes p. 389Hydraulic system performance loss with slow response and boom cylinders moving slowly
Check the hydraulic tank level and verify the system holds its full 81 Liters capacity. Test the pump flow specification to ensure it outputs 57.5 Lit/min at 1000 RPM as shown on page 411. Clean or replace the 10 micron mesh suction filter to restore proper flow.
Manual Section: Hydraulics p. 411Track chain sags excessively and track sprockets slip during heavy bucket loading
Measure the track chain tension by checking the sag between the idler and carrier roller. Adjust the track release cylinder until the sag measures 30-40 mm as detailed on page 522. Inspect the sprocket ring gear and verify it has exactly 28 teeth with a 74 mm tooth width.
Manual Section: Undercarriage p. 522Frequently Asked Questions
What are the replacement specifications for Steering clutches?
The clutch pack thickness for steering clutches should be between 103-106 millimeters (4.055 - 4.173 inches). The maximum allowable disc wear (total) is 5.5 millimeters (0.217 inches). When checking the clutch stack height, the total thickness should be 83-86 mm (3.268-3.386 in.) under a load of 294-392 daN (659-879 lbs). p. 389
What are the replacement specifications for Hydraulic control valves?
For hydraulic control valves, the spools are matched to the valve body to achieve a fit clearance of 0.010 - 0.015mm (.0004 - .0006 inches). p. 452
What is the engine oil capacity?
The engine oil capacity is 12 liters (3.17 gallons) for refill. p. 68
What is the fuel tank capacity?
The fuel tank capacity is 260 liters (69 gallons). p. 68
