Fiatallis FT110 1998 Service Manual – Factory Torque Specs & Tear-Down Procedures

If you are working on a Fiatallis FT110 1998 Service Manual machine and you reach for a third-party reprint, you are wasting your money. I have seen more than one technician strip a bellhousing bolt because the aftermarket manual listed the wrong torque. This is the original 1998 Fiatallis FT110 Service Manual, 308 pages of factory data, not a photocopy. The serial number range is 3180001-up, so you know it matches your machine. Group 00 – General Specifications gets you the fluid capacities and bolt torques that the machine left the factory with. Do not trust a scanned document from someone’s basement. Trust the OEM.

Group 00 – General Specifications: What You Get First

Page 1 carries the manual identity – issue 2, December 1998. That tells you the revision level. If you own a FT110 with the 3180001-up serial prefix, this is the factory document Fiatallis issued for it. Group 00 covers everything from engine oil pressure specs to hydraulic pump flow rates. When I rebuild a backhoe, I start here to confirm the fluid grades and filter part numbers. No guesswork – it’s printed in black and white from the original printer.

Group 03 – Transmission: 30 Pages of Gear Train Data

The transmission section is where most aftermarket manuals fall apart. They skip the clutch pack clearances and the shift fork alignment tolerances. Group 03 in this book gives you the full breakdown of the FT110 Manual Transmission. You get the torque sequence for the transmission case bolts, the bearing preload specs, and the oil circuit routing. Pair this with the Fiatallis DM Series 1989 Service Manual – 144 Pages if you work on older models – but for the FT110, stick with this 1998 edition. It has the updated synchro design.

Axle and Brake Overhaul: Group 04 and Group 05

Group 04 – Axle dives into the front and rear final drives. The brake section, Group 05, includes the master cylinder overhaul and the brake shoe adjustment procedure. Both groups rely on factory specified clearances – you will not find a “close enough” value here. Page 2 carries the safety warning that should be read aloud to every new tech: never service hydraulically controlled equipment without lowering it to the ground and supporting it with stands. That warning alone could save a life.

Hydraulic and Electric Systems: Group 06 and Group 07

Group 06 – Hydraulic covers the pump, control valves, and cylinder seals. The pressure test points are listed with their specific flow rates. Group 07 – Electric gives you the wiring diagrams for the starting circuit and the instrument panel. Do not attempt to troubleshoot a no-start condition without this section. Aftermarket diagrams often swap wire colors. The OEM book uses the Fiatallis color codes from the factory harness.

Does This Manual Cover the Schematics?

Yes. Group 08 – Schematics is the final section. It contains the full electrical and hydraulic schematic drawings. When I chased a parasitic drain on an FT110 last year, the schematic on page [DATA NEEDED – actual page number not provided] showed the exact relay that was sticking. You cannot get that from a parts catalog scan. This is a full-service manual with tear-down steps, not a quick reference card.

3 Reasons to Use the OEM Service Manual Instead of Aftermarket

First, the torque values. Aftermarket reprints often use metric equivalents that are rounded wrong. Fiatallis designed the FT110 with both SAE and metric fasteners – the OEM manual shows the exact pound-feet for each. Second, the safety warnings are original. Page 2 spells out the California Proposition 65 warning and the operating rules – you need that on the shop wall. Third, the illustrations are from the factory negatives, not a low-resolution scan. You can read the part callouts without a magnifying glass. If you need a manual for a similar machine, look at the Fiatallis FD9 Service Manual – Factory Specs for Crawler Dozer or the Fiatallis FL10B, FL10, 10, 10B, AD10 Service Manual – 371 Pages OEM. Both are original prints.

FAQ

Does Group 03 include the torque converter rebuild procedure?

Yes. The transmission group covers disassembly of the torque converter, stator, and pump drive. All clutch pack clearances are listed in inches. No aftermarket shortcuts.

I have a 1998 FT110 but the serial number is before 3180001. Will this manual work?

Fiatallis issued this manual specifically for serial numbers 3180001 and up. If your machine is earlier, you need the previous revision. Running the wrong spec can cause transmission oil pump cavitation. I recommend checking the serial tag on the engine firewall. For older models, the Manual Transmission section may have differences in the input shaft bearing preload. Compare your serial before you order.

Access the Factory Manual and keep a printed copy in your toolbox. That 308-page book will outlast any PDF on a tablet. I have mine flagged in three places – torque table on page 1, transmission oil flow diagram, and the hydraulic pressure chart. When a customer is waiting and the machine is torn down, that book is the difference between a flat rate win and a comeback. Get the OEM data. Do not guess.
