Fiatallis 300 Parts Catalog – OEM Factory Specs for Parts Identification

Every mechanic knows the feeling: you order a seal, wait three days, and it’s the wrong bore diameter. That stops here. The Fiatallis 300 Parts Catalog is 242 pages of factory-sourced part numbers and exploded diagrams. It’s not a service manual—it’s the parts bible.

This is a parts catalog, not a repair manual. If you need torque specs or overhaul steps, look for the service manual. For ordering the correct bearing, seal, or hose, this is your only source.

Parts Identification: Why OEM Catalog Data Matters

Aftermarket parts books skip details. Factory documentation includes every revision and variant. The Fiatallis 300 Parts Catalog lists parts by subgroup, with exploded views that show exactly how each piece fits. You get the factory part number—not a cross-reference that might be wrong.

For a mechanic, using OEM documentation means you order once. You don’t waste time returning mismatched components. That’s money in your pocket.

How to Use the Catalog: Page 9 Instructions

When you open this catalog, you’ll see instructions in five languages. Turn to page 9 for the English version. Read it. The numbering system and table layout are explained there. If you skip this, you’ll order wrong. I’ve seen it happen.

First, identify your machine from the model list on orange paper (page 11). Then check the variant list (page 13) for any differences. After that, the subgroup index on page 17/1 points you to the right section.

Fiatallis 300 Parts Catalog: Navigating the Subgroup Index

The subgroup index (page 17/1) is your roadmap. It breaks the machine into systems: engine, transmission, hydraulics, electrical, and more. Each subgroup leads to a table with an exploded diagram and a list of part numbers. The spare parts index starting on page 19/1 gives you an alphabetical and numerical cross-reference.

For example, if you need a hydraulic pump seal, you find the hydraulic subgroup, locate the pump assembly in the table, and read the part number. Then verify it in the index. That’s the process.

3 Reasons to Order OEM Parts from the Factory Catalog

There are three solid reasons to use the factory catalog for parts:

• Correct part numbers: Every number matches the factory build sheet. No aftermarket guesses.
• Fitment assurance: Exploded views show orientation and quantity. You see what you need.
• Availability information: Some parts are superseded; the catalog notes changes.

These are not promises from a third party. This is the original Fiatallis documentation.

Bearings, Cables, and Terminals – The Tables Section

Starting on page 1T, the catalog includes separate tables for bearings, electrical cables, terminals, and insulating tubing. These are often the parts that get ordered wrong. Bearing numbers from the factory are stamped on the race; the table confirms it with inner/outer diameters and load ratings. Electrical cables are listed by length and terminal type—no guessing which gauge fits which lug. If you’re rewiring a 300 series, these tables save hours of counting wires and measuring lengths. The terminal caps and insulating tubing tables include part numbers for every connector used on the machine. Each entry specifies the correct crimp tool and color code. Don’t trust a generic terminal from a local store; get the OEM part and sleep well. Cross-reference every number with the spare parts index on page 19/1 to confirm supersessions. That diligence is what separates a job done once from a redo. It’s the only way to ensure your machine runs like it left the factory.

For background on why OEM documentation matters in the Automotive Industry Overview, you can see how standardization and part traceability affect repair quality. The same principle applies to construction equipment.

Frequently Asked Questions

Is this a repair manual or a parts catalog?

It’s a parts catalog. For repair procedures, get the service manual.

How do I ensure I’m ordering the correct part for my Fiatallis 300?

First, consult the ‘Use of the Catalog’ on page 9 to understand the layout. Next, locate your model in the model list on orange paper starting at page 11. Then identify your machine’s variant from the variant list on page 13. With that info, turn to the subgroup index on page 17/1 to find the section covering your system—engine, transmission, hydraulics, etc. Each subgroup directs you to a specific table page where you’ll find an exploded diagram and a list of part numbers. Cross-check the numbers with the spare parts index starting at page 19/1. The tables for bearings, cables, and terminals start at page 1T. It’s a systematic process that eliminates guesswork.
