Fiatallis 745, 745H 1990 Parts Catalog – No Guessing, Just Factory Numbers

If you’ve spent an afternoon digging through aftermarket parts catalogs only to find the wrong seal for a 745 wheel loader, you know what I’m talking about. That’s time you don’t get back. This Fiatallis 745, 745H 1990 Parts Catalog is the original factory document – 479 pages of part numbers, illustrations, and cross-references that the assemblers used themselves. No reprint, no third-party interpretation. It covers both the 745 (serial 1001 up, 96M02050 up, 87L02050 up) and the 745H (serial 23CO2248 up, 84U02248 up). If you’re ordering a bearing, bushing, or hose assembly, this is the only source I trust.

Parts Catalog Content: What You Get

Every section from the OEM catalog is here: axle components, brakes and air system, bucket and chassis, electrical system, engine, loader hydraulic system, and power steering system. That’s seven major systems, all split out with factory part numbers and exploded diagrams. Need the injection pump number for a Roosa or Robert Bosch? It’s in the catalog. The electrical system section includes alternators and starters with their own form numbers. You don’t guess – you look it up. Page numbers aren’t labeled in the PDF bookmarks beyond simple sequential pages, but the original pagination is intact from the 10/90 reprint (Form 73064203).

Safety First: The Manual’s Warning on Page 2

Flip to page 2 and you’ll see the factory safety warning in bold: “Never attempt to clean, oil or adjust a machine while in motion.” Also states that on hydraulically or cable-controlled equipment, you lower the load to the ground before servicing. If you need to raise it for access, support it with something other than the hydraulics. I’ve seen too many guys skip that step and end up with a loader bucket in the lap. This catalog doesn’t replace the service manual for torque specs, but it does list every part number you’ll need to order for a safe repair.

Why OEM Parts Catalog Beats Aftermarket

Aftermarket parts books often lump serial number breaks together or omit supersessions. The Fiatallis catalog gives you the exact part number for your 745 or 745H based on the serial number range. For example, the bucket and chassis section (form 73055458) is specific to the 745. If you have a 745H, you use form 73057885 for the O&M manual, but the parts catalog covers both models in one book. That’s how the factory did it. Don’t waste money on a generic parts list that says “fits many models.” This book tells you exactly which hardware fits your machine. Related manuals like the Fiatallis HD-9 1989 Parts Catalog – OEM Factory Specs and Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog follow the same OEM standard. The Fiatallis HD-21 1990 Parts Catalog – Crawler Tractor Parts Manual is another factory document you can pair with this for undercarriage cross-referencing.

Using the Catalog on a 745H Wheel Loader

Take the brake and air system. The factory form number for the brakes service manual is 73067178, but the parts catalog shows each brake shoe, seal, and air valve with its own number and quantity. When you’re doing a brake job on a 745H, you order from this catalog. The same applies to the loader hydraulic system – you’ll find the lift cylinder seals and hoses listed by section. If you’re sourcing components from suppliers who want a part number, give them the number from page 479 or wherever it’s listed. Without this catalog, you’re gambling. The Automotive Industry Overview might give you general context, but it won’t tell you the right O-ring for your 745. Only the OEM catalog will.

7 Systems Covered – Each With Factory Part Numbers

Here’s the breakdown from the additional publications page: Axle, Brakes & Air System, Bucket & Chassis, Electrical System, Engine, Loader Hydraulic System, Power Steering System. All seven are in this 479-page Parts Catalog. The engine section covers the full engine assembly (form 70645121 service manual reference) and the injection pumps (Roosa form 70685399, Robert Bosch forms 70690916 and 70698576). If you need a piston ring or a fuel line, you look up the part number here. No guessing, no cross-shipment returns. The Automotive Industry Overview is interesting but irrelevant when you have a loader down in a trench.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and illustrations. Torque values and repair procedures are in the separate service manuals listed on page 3.

What serial numbers does the 745H section cover?

The catalog covers 745H serial numbers from 23CO2248 up and 84U02248 up. If your machine falls in that range, the part numbers are correct. If earlier, you might need a different edition. Always verify with the serial number page at the front of the book.

After you’ve used an aftermarket list and ordered the wrong part, you’ll appreciate what 479 pages of factory data means. This catalog is a PDF format – searchable, printable, and exact. Access the Factory Manual from AutoRepairManuals and keep it in your shop tablet or phone. Next time you need a part for a 745 or 745H, you’ll have the number in ten seconds, not half an hour.
