Fiatallis 945-B 1989 Parts Catalog – OEM Factory Specs

Look, I’ve got a pile of aftermarket parts catalogs on my shelf that are wrong about half the time. That’s why when you’re ordering a hydraulic seal or a final drive bearing for a Fiatallis 945-B 1989 Parts Catalog, you pull the factory book. This manual is 384 pages of the only numbers that matter – the ones stamped on the part when it left the plant. If you’ve ever tried to match a transmission gasket off a third-party drawing, you know the sick feeling when it doesn’t fit. Save yourself that headache.

What’s in This Fiatallis 945-B 1989 Parts Catalog?

This isn’t some reprint from a copy shop. This is the original Fiatallis Parts Catalog for the 945-B wheel loader, serial numbers 15M01128-UP and 77S02101-UP. Published August 1989, form 73064395. It covers every assembly on the loader – engine, transmission, torque converter, axles, hydraulic system, electrical. Plus it includes the special supplement form 731448 for loaders equipped with the optional Cummins NTA-855-C-630 engine. That supplement adds and revises pages 33, 39A, 48, 49, 53A, 61, 63A, etc. You need that supplement if you’ve got the Cummins, or you’ll order the wrong injection parts.

Parts Breakdowns and Diagrams

Each section of this manual gives you an exploded-view drawing with callouts and a parts list. Not a vague sketch – a factory drawing. You get the exact part number, description, quantity, and sometimes a note about supersessions. Want to find the correct steering cylinder seal kit? You look up the assembly page, read the number, order it. No measuring, no guessing. This is how you keep a 945-B loader working without chasing obsolete numbers.

Safety First – The Warning You Can’t Skip

Flip to page 2 of this catalog and you’ll see the “AVOID ACCIDENTS” warning. It’s not just lawyer talk. Fiatallis spells it out: never clean, oil, or adjust a machine while it’s in motion. If you have to raise the bucket or boom to access parts, support it with stands – not hydraulic cylinders. I’ve seen a boom drop because a tech trusted a cylinder seal. That warning is there for a reason. Don’t skip it because you’re in a hurry.

384 Pages of Factory Specs

Three hundred and eighty-four pages. That’s the thickness you need to cover the entire 945-B. Each page is numbered and some are marked “Revised” or “Added” in the supplement – page 53A added, page 77 revised. That level of detail tells you the factory updated the catalog as they improved the machine. You get the latest part numbers as of 1989. Compare that to an aftermarket CD that gives you a generic PDF – no comparison.

Who Needs This Manual?

If you own a Fiatallis 945-B wheel loader, or you’re a shop that services them, this catalog is your parts bible. DIY mechanics who handle their own repairs need it to order the right parts from the dealer. Shop owners need it on the counter so technicians don’t waste time cross-referencing. And if you’re rebuilding a 945-B, you need the exploded diagrams to know what every bushing and seal looks like before you start.

This manual is part of a larger collection of Fiatallis literature. For other models, check out the Fiatallis HD-9 1989 Parts Catalog – OEM Factory Specs or the Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog. For a larger crawler, the Fiatallis HD-21 1990 Parts Catalog – Crawler Tractor Parts Manual covers that machine.

Factory parts catalogs like this have been the backbone of the automotive industry for decades. When you need to know which bearing goes where, OEM documentation is the gold standard. For more on why OEM data beats aftermarket, the heavy equipment documentation practices reinforce that lesson.

Is this a repair manual or parts catalog?

Parts catalog. It lists parts with diagrams, not repair steps.

Does it include the Cummins engine supplement?

Yes, this specific copy includes the special supplement Form 731448 for the optional Cummins NTA-855-C-630 engine. Pages 33, 34, 39A, 48, 49, 53A, 61, 63A, 65, 66, 67A, 77, 77A, 78, 79, 80, 81, 82, 82A, 109, 109A are either revised or added. That supplement is critical because many engine-specific parts – injectors, pistons, gaskets – differ from the base Cummins. Without it you’d be ordering components that don’t fit the 945-B installation. The supplement is integrated into the page sequence, so you have to use it alongside the main catalog every time you pull a part number for the engine.

I’ve been turning wrenches for twenty-eight years. I know the difference between a genuine OEM document and a scanned copy that lost its resolution. This Fiatallis 945-B 1989 Parts Catalog is the real thing – factory-original, 384 pages, with the supplement. If you need to buy parts for your loader, this is where you start. Access the Factory Manual directly from AutoRepairManuals and keep it on your bench. Your parts counter will thank you.
