Fiatallis 345B Parts Catalog

Ordering parts for a Fiatallis 345B without the factory part numbers is a fast way to stack up wrong boxes and burn through your budget. I’ve watched guys pull a hydraulic line, eyeball the length, and order something close — then spend a whole afternoon fighting a fitting that doesn’t match. This Fiatallis 345B Parts Catalog is the OEM document that tells you exactly which part goes where, by serial number, with all the changes Fiatallis published. 271 pages, factory print, no aftermarket guesswork. FIATALLIS 345B Parts Catalog is the foundation for keeping that loader in the dirt and out of the shop.

Engine Assembly: Finding the Correct Part Number

Page 2 of this catalog lists a change for the engine assembly: the original part number 74024448 was superseded by 73141998. If you order by the old number, you’ll get a part that may not match your loader’s build date. The supplement included in this book, dated 4-77, shows those part number shifts in underlined text. That’s the kind of detail you don’t get from third-party reprints. Match your serial number — 76L01895 through 76L01901 for this supplement — and order the right block the first time.

Hydraulic Cylinder Design Change – Know Your Serial Number

The OEM catalog explicitly states on page 2 that the cylinder design listed on pages 15 and 16 of the base catalog (Form 73067179) is replaced by the design on pages 2 and 3 of this supplement. That means the old cylinder assembly won’t bolt up to loaders after a certain break point. If you’re rebuilding a 345B and you skip checking the supplement, you might end up with a cylinder that has different port locations or rod diameters. The catalog gives you the exact new part numbers: shaft 74009186, tube 74008354, and housing 74008289. Don’t guess – use the serial number range to verify.

Attaching Parts: Why the Indentation Matters

Page 5 of the catalog has a note I wish every parts guy would read aloud: “Attaching parts such as bolts, nuts, rivets, screws, washers, etc., are indented immediately following the parts which they attach.” That indentation tells you what fasteners go with what assembly. When you’re rebuilding a final drive or a pump, you need those washers and bolts listed in the right sequence. This catalog lays it out so you can grab the correct capscrew or washer without flipping back and forth through a messy index.

Supplement No. 1: What Changed Between Printings

Page 3 of this document states that Supplement No. 1 (4-77) is included, along with all changes issued on microfiche through June 1979. That means this catalog captures years of field revisions. For example, the gauge assembly changed from part number 74024704 to 74023934. The adaptor assembly went from 74023877 to 74024181. These are not trivial swaps — thread pitches and port sizes can differ. If you’re using a copied manual from a third-party site, you likely don’t have these updates. This factory version has them, bound in the same book.

Using the Parts Catalog with Service Publications

Page 4 directs you to the Service Publications Index Form 73150687, available free from Fiatallis. That index lists all the technical manuals for this model — service, repair, operation, and more. If you’re serious about maintaining a 345B, you’ll want that index alongside this parts catalog. The catalog gives you the numbers, but the service manual gives you the procedures. Together they’re the whole picture. For background on the Automotive Industry Overview, you can see how factory documentation prevents costly missteps on heavy equipment. Automotive Industry Overview also underscores why OEM data is non-negotiable.

Page Count and Structure: 271 Pages of Factory Data

This is a 271-page document, paginated from cover to cover. Every page has a part illustration and a list of part numbers with quantities and descriptions. The table of contents is built into the page numbers — you navigate by the section breaks for engine, transmission, hydraulics, and attachments. If you need a part, you find the group, read the indentation, and write down the factory number. No cross-referencing with aftermarket catalogs that might use a different numbering scheme.

Does this catalog include part numbers for the engine?

Yes. Page 2 lists the engine assembly change with the new part number 73141998. You’ll need the base catalog (Form 73067179) for the full engine section.

How do I know which supplement applies to my loader?

Each supplement in this catalog is tied to a serial number range. For example, the special supplement on page 2 applies only to loaders serial 76L01895 through 76L01901. To identify which supplement covers your machine, locate your loader’s serial number plate, then compare it against the ranges printed on each supplement title page. If your serial falls outside the listed ranges, you must refer to the base catalog without supplements for that section. Missing this step is the number one reason guys order parts that don’t bolt up. The catalog also includes Supplement No. 1 (4-77) and all microfiche changes through June 1979, so even if your serial is not in the special supplement, you still have the later revisions.
