Fiatallis 14C Parts Catalog – OEM Factory Specs for Engine & Transmission

If you’re wrenching on a Fiatallis 14C and need to track down the exact part number for a piston ring set or a transmission shaft seal, this is the file that keeps you from ordering three wrong parts before you get one that fits. I’ve seen too many mechanics trust an aftermarket parts list and end up with a clutch disc that’s two splines off. This Fiatallis 14C Parts Catalog is the original factory document – 96 pages of exploded diagrams and part numbers that match what came off the line in San Antonio and everywhere else these crawlers worked. No guesswork, no “close enough” dimensions.

Engine Parts Breakdown (Section A)

Section A covers the engine – MOTORE in Italian, MOTEUR in French, MOTOR in German. You get the full listing of cylinder head components, pistons, rings, bearings, gaskets, and all the internal hardware. If you need the part number for a valve spring retainer on a 14C, you flip to this section and find it indexed by subgroup. The alphabetically index starting on page 1-A15 lets you cross-reference by part name in five languages. That matters when the old part tag is worn off and you only have a vague description.

Mechanical Transmission and Clutch (Section B)

Section B spells out the mechanical transmission – clutch, transmission shafts, axles. The factory lists every gear, synchro, bearing, and seal. When a customer brings in a 14C with a grinding third gear, you don’t pull the transmission blind. You pull the catalog, find the part number for the gear set, and order exactly what you need. The diagrams show exploded views with callouts pointing to each part. Follow those numbers. Aftermarket catalogs often combine multiple variants into one generic part – this catalog separates by serial number range where applicable.

Brakes: Mechanical or Hydraulic (Section C)

Brakes on these crawlers can be mechanical linkages or hydraulic actuation. Section C lists both variants with separate part numbers for shoes, drums, cylinders, and linkage pins. If you’re converting a mechanical brake to hydraulic, you’ll need the correct master cylinder and line parts. The catalog gives you the OEM spec – not a “universal” replacement that requires bracket fabrication. I’ve done that route. It costs more time than buying the right part the first time.

Undercarriage and Frame (Section D)

Section D covers frame, steering, suspensions, wheels, undercarriage, and hydraulic transmission. For a crawler, the undercarriage is where the money lives – rollers, idlers, sprockets, track chains. The 14C undercarriage has specific track chain pitch and roller diameters. This catalog lists the OEM part numbers so you don’t end up with mismatched chain links. The frame section includes steering box parts and suspension bushings. Every bushing has a length and ID. Aftermarket listings rarely give you that level of detail. Page references in Section D – see the index to locate specific subgroup – let you zero in on the exact assembly.

7 Systems Covered: From Air to Electrical

Beyond the major assemblies, this catalog covers electrical system (Section F), air system (Section G), body panels (Section L), driver’s seat (Section M), tools (Section Z), and tables (Section T). The tables section (T) lists torque values? Actually, the catalog doesn’t provide repair torque specs – that’s a service manual job – but it does give you part numbers for hardware like bolts and nuts. If you need a specific grade 8 bolt for the transmission housing, look in the subgroup under “bolts” in the numerical list (page 1-C6). The air system section (G) includes compressor parts and valve assemblies. Electrical section (F) covers alternator, starter, wiring harness connectors. These are parts you cannot afford to guess on because a wrong starter motor might not mount up or the B+ terminal location could hit the frame. We sell the factory wiring diagram separately in related manuals if you need that level of detail.

Does This Manual Cover the Steering and Suspensions?

Yes. Section D specifically includes steering components and suspension parts. But note: this is a parts catalog, not a repair manual. You won’t find alignment procedures or adjustment specs. For that, you want the factory service manual. This catalog gives you the part numbers so you can order the correct steering cylinder seals or suspension arm bushings. If you’re rebuilding the steering system, grab this catalog alongside the service manual to make sure the seals you order match the bore dimensions of your specific 14C variant.

Source Validity: OEM Factory Print vs Aftermarket Copies

This file is a direct scan of the original Fiatallis publication – not a reprint from a third-party publisher that might have dropped pages or merged sections. It contains five-language headers (English, Italian, French, German, Spanish) because Fiatallis built these machines for global markets. The part numbers follow the original 14C production codes. Aftermarket catalogs often substitute “generic equivalent” numbers that cross-reference incorrectly. I’ve seen a track roller marked as “fits D6 and 14C” that had a different flange width – it would have thrown the track alignment off by 3/8 inch. Stick with the OEM source. The automotive industry runs on precision; construction equipment is no different.

Every section is subdivided by subgroup – for example, the alphabetical index (1-A15) lets you find “piston ring” and get the subgroup number. Then you go to the subgroup page in Section A and read the diagram callout. It’s systematic. The table of contents lists all major sections A through Z, plus the lists of cancelled and new parts from updates (Section X and Y). If you’re working on a later serial number, check Section Y for supersession numbers. That’s a feature aftermarket catalogs never include.

I keep a copy of this catalog on my tablet in the shop. When a customer brings in a 14C that needs a transmission overhaul, I pull up Section B, find the bearing numbers, order them, and the job goes smooth. No second-guessing. You can get the same result. Access the factory manual Automotive Industry Overview page for context if you want, but the manual itself is what you need on the workbench.

FAQ

Can I use this catalog to find torque specifications for the cylinder head?

No. This is a parts catalog, not a service manual. It lists part numbers and exploded views. Torque values appear in the factory service manual, which we sell separately.

How do I find a part number if I only have the old part in my hand?

Measure the part dimensions (length, diameter, thread pitch) and then use the alphabetical index (page 1-A15) to locate the subgroup. For example, a bearing with 2.5-inch OD and 1.0-inch ID – look under “bearing” in the index. The cross-reference will lead you to the correct subgroup in Section D or B. If the part has a stamped number, you can also search the numerical list (page 1-C6) which lists part numbers in ascending order. That’s the fastest method when the number is still legible.
